Do-it-yourself dion geyser repair. Why does the gas column go out? Repair of geysers. Flowing gas water heater

Flowing water heaters on gas, or in other words - gas water heaters, allow you to living conditions receive hot water and use it for its intended purpose. Despite all the amenities delivered, these units are not without weaknesses because they break from time to time.

If it doesn't light up geyser, then to eliminate the consequences of the malfunction, you must call the wizard or try to fix the device yourself. But before you do something, you should deal with the causes of the breakdown.

Causes of malfunctions

Since most models of gas water heaters have the same device (they work on a similar principle), the impossibility of starting them is due to the following typical reasons:

• no ignition (no normal spark);
• normal draft in the air outlet is broken;
• water is supplied with low pressure;
• the pressure of the coolant (gas) is weakened;
• accumulation of scale and blockages;
• problems with the electronic protection module.

In cases where the column was not in use long time, the cause of its malfunction may be the accumulation of a large amount of air in the gas pipeline. For removing air locks a short-term bleeding of them (for a minute or a little more) is enough.

Let's deal with each of the above reasons, explaining why the geyser goes out in more detail.

No ignition

If for some reason the column does not ignite at all, the first thing to check is the battery that powers all electronics (including the piezo ignition system).

When the water heater is powered by a built-in generator, you should make sure that the piezoelectric element is in good condition, as well as that there is no break in the supply wires. In addition, it is necessary to inspect the electrode (wick) for damage.

The same actions are performed when the power supply is working. If it turns out that the battery has run down or leaked, you just need to replace it. In the absence of clearly visible external damage, check the condition of the ignition elements with a multimeter. With it, you should ring the lead wires and the start button. In case of their serviceability, it will be distributed sound signal, in the presence of an open circuit, the device will show an infinitely large resistance.

The same device, included in the voltage measurement mode, checks its presence at the input contacts of the ignition element. The presence of a certain potential on them indicates that all parts are in good order, except for the piezoelectric element.

Bad traction

The reason that the column does not ignite, or ignites, but suddenly goes out, happens bad traction. You can detect the loss of normal draft by simply lighting a candle or match and bringing them to the junction of the outlet channel of the gas column with the chimney. With a normal thrust value, the flame will deviate towards the gap, and in its absence, no changes are observed. Usually in this situation heating device begins to make sounds resembling clapping.

If this effect is detected, due to which the column stops working normally, it is necessary to urgently take measures to eliminate it, for which the following steps must be taken:

• check the chimney for clogging with foreign objects or debris;
• determine the level natural ventilation in the apartment (special attention is paid to plastic windows);
• deal with what is available at the column exhaust device capable of taking on some of the thrust.

To eliminate blockage in the chimney (unless it is associated with accidental entry into the channel foreign object) it is best to contact the public utility, whose representative will clean it of accumulated soot and dirt.

To restore normal air pressure in the room, simply open the sash of the plastic window. Well, if an excessive outflow of air into the hood is detected, it is best to turn off the latter for the duration of the ignition of the gas column.

Weak outlet water pressure

Despite the presence of a special machine that regulates the water pressure, many users complain about the inconstancy of this indicator. With a changing supply force, it is almost impossible to wash in the shower - the gas goes out, the column does not ignite well, and the water does not heat up. Surgery is required to determine the cause of this instability. The main reasons for the formation of such differences in water pressure are the following three factors.

The declared power of the device does not correspond to the real need for water resource, the power is not enough to meet normal daily needs.

Important! In order to avoid similar situation, you need to worry about purchasing a column for 8-10 kilowatts (at least).

The presence of contamination in the water entering the column is due to the fact that small particles of debris, lime and pieces of rust have accumulated in the supply system.

The formation of scale on the walls of the column radiator, due to which it can also turn off. The last two causes of problems are worth considering in more detail.

Fight against blockages and scale

A thick layer of scale can cause the column to stop igniting. To trap debris even before water enters the gas heater, it is necessary to install at the inlet to it strainer, which must be periodically cleared of the resulting accumulations. Before cleaning this element, shut off the gas and water supply, and then disconnect the flexible hose suitable for the receiving unit. After that, it remains only to remove the filter and rinse in running water.

Advice! If the filter is heavily soiled, it is recommended to use a hard metal brush to clean it. If this does not help, you can try soaking it in an acid solution.

Scale formation is explained by the features of the device gas unit working on the principle instantaneous water heater. Here the water also passes through the heat exchanger and is also heated by the burner. With this heating method, processes occur that are accompanied by the formation of magnesium and potassium salts, deposited on the radiator elements in the form of a layer limescale. Over time, it expands so much that water passes through the radiator with great difficulty, which is the reason for the decrease in pressure.

Water supply problems

If the blockage in the heater has spread all the way to the inlet mixer, the pressure will drop so much that the column will not ignite, and urgent measures cannot be dispensed with. In this case, you must immediately clean the inlet assembly by completely disassembling it and washing running water from a rubber hose. The gas column filter itself and the parts adjacent to it are subject to the same cleaning.

It follows that the reason low pressure water and one of the reasons that the column began to turn off is the lack of timely care for home appliances. That is why experts recommend periodically carrying out its prevention (at least once a year).

Problems with the water supply can also arise due to low pressure in the line. But in this case, the consumer decides practically nothing, and all he can change is to try to include in the system additional pump. However, this technique is acceptable only for owners of private houses. In apartment buildings, you can complain to the maintenance company.

Problems with electronics and gas block

There are frequent situations when the wick does not light up due to the fact that the feed is constantly blocked gas fuel. This is explained by the fact that, most likely, the protection system that is equipped with equipment with electronic ignition is triggered.

This system includes a thermocouple heated by a special igniter and generating voltage, which, in turn, turns on an electric valve that starts the working mixture into the burner, after which the gas starts to burn.

Note! After the entire system is put into operation, the thermocouple is heated from a burning wick.

Any professional will tell you: "the gas water heater is potentially dangerous equipment, so you can only trust its maintenance and repair to a qualified specialist." However, the ability to understand exactly which element has failed and what it can lead to definitely does not hurt.

In addition, you can deal with the elimination of some malfunctions that do not specifically affect gas equipment on your own. Read the description of typical breakdowns and recommendations for action in case of their discovery.

Equipment can stop igniting for several reasons.

First of all, you must make sure that the igniter is working. If it does not light up, contact the gas service. The specialist will clean or replace the failed element. You can't touch it yourself - it's dangerous.

In modern ones with electronic ignition, in the absence of ignition, the gas stops supplying - the valve cuts it off. The user learns about it by means of the corresponding indicator. In some situations, this problem is solved by simply replacing the battery. Check this point in the instructions. If the manufacturer does not give such recommendations, it is better to immediately contact the gas service or a third-party repair service.

The column will not ignite in the absence of traction. To check the level of thrust, we bring a strip of paper to the ventilation grille. If the leaf does not change its position, or if it does not change it sufficiently, there are obvious problems with traction. In apartment buildings, public utilities are engaged in cleaning ventilation wells - contact them. You can do it yourself with a metal brush tied to a suitable length. flexible wire(hose, etc.), however, such unauthorized actions are usually not approved by utilities.

Often the burners do not work due to the wear of the membrane. This structural element deforms quite quickly, the burner start mechanism becomes less sensitive and does not work when the water is turned on. Even in expensive heaters, membranes wear out in 5-8 years - unfortunately, nothing can be done about this.

To check, turn the water on to the maximum. If the column turns on with strong pressure, the problem is definitely in the membrane. You can replace this element on your own.

To do this, do the following:

• unscrew the fastening nuts from the water unit (usually there are 2 of them);
• unscrew the fixing screws, due to which the water unit is held in the gas unit (usually 3 screws);
• separate the halves of the assembly and you will see a rubber membrane. If it is not flat but noticeably deformed, replace it. To do this, buy a similar product from a specialized store. If possible, give preference to a silicone membrane - it will last much longer than its simple rubber counterpart.

At the same stage, you can check the condition of the water intake filter. If it is clogged, clean it or replace it with a new one. For cleaning, simply unscrew the nut on the water supply side, remove the mesh and wash it or replace it with a new one, depending on the condition.

find out detailed instructions how to produce, from our new article.

If the heater turns on but goes out, the problem in most situations is the bimetal temperature sensor, which is necessary to protect the equipment from overheating. Also, due to malfunctions of this element, the heater may not turn on at all.

This problem has 2 main development scenarios.

It does not make sense to contact the gas workers - the defect is clearly not “gas”. Trying to get rid of the breakdown yourself is also not necessary - you can only break the unit. Contact service center for warranty repairs.

Most often this happens due to clogging of the column heat exchanger with scale. Usually the cause of clogging is prolonged "idle" firing of the igniter. The device heats the heat exchanger to a temperature sufficient to lead to the evaporation of residual moisture.

There is no water flow, scale is not washed out of the heat exchanger, up to next inclusion equipment, it seizes, as a result of which the column ceases to function normally. Usually cleaning the heat exchanger saves. In advanced cases, it has to be changed.

For replacement, it is better to immediately contact the professionals, but you can handle the cleaning on your own. Get your screwdrivers ready rubber hose, open-end wrenches and paranitic gaskets. Purchase a descaling compound from the hardware store. Usually it is called so - antinakipin. More a budget option- washing with vinegar essence. Work in that order.

First step. Sequentially remove the fittings and casing from the heater.

Second step. Shut off the inlet water and open the faucet hot water, preferably as close as possible to the column.

Third step. Unscrew the water supply pipe from the heat exchanger, and then move it to the side. After unscrewing the nut, the column heat exchanger will begin to give water. In total, about 1 liter will be drained.

Fourth step. Attach a hose of suitable diameter to the inlet of the heat exchanger and lift it just above the heater. Insert an ordinary funnel into the fixed hose and start pouring slowly, in a thin stream ready solution(preparation instructions are on the packaging). There is no need to hurry. If you pour too quickly, the antikipin will simply be pushed back, and you are unlikely to like it.

Leave the cleaner in the heater coil for 2-3 hours (usually required time indicated on the package).

Substitute under the water tap suitable capacity and carefully restart the fluid supply to the heater. Watch what comes out of the hose. Enough sludge came out, and then the pressure returned to normal? Everything is fine. Otherwise, flushing will have to be repeated. Usually, the need for re-rinsing arises only when using vinegar essence. Antinakipin in most situations copes the first time.

In such a situation, it is better to immediately contact a professional. He will make an adjustment, which is extremely difficult to make without knowledge of the matter, and the column will start working normally.

You can also find out the reasons for the appearance of such a malfunction for general development. There are two main reasons:

• the gas flow is too high. The heater lights up too actively, which leads to a breakdown of the fire;
• the gas flow is too low. Air enters the burner of the heater, which leads to a microexplosion, which is regarded by human hearing as cotton.

This is usually due to not being high enough. The user begins to demand more from the equipment than it can do.

There are two options for solving the problem:

• we stop abusing and do not simultaneously open hot taps at all points of water intake;
• buy a more powerful one.

Also, inadequate heating of the liquid can occur due to clogging of the burner. Look at the color of the fire. AT normal conditions he is bluish. If the flame turns yellow, contact the gas workers. You can trust such repairs exclusively to a professional, because. This is already a "gas" failure.

When you turn on the heater, it starts to smell like gas

The problem is more than serious. Don't even think about doing your own repairs. Turn off the heater, turn off the gas valve, keep the home well ventilated at all times and call the gas service immediately. The on-site team will assess the problem and take appropriate action.

Now you know the main malfunctions of the geyser, and you know how to behave when they appear. The main thing is to remember safety. No need to try to fix breakdowns for which you do not have the qualifications - this can lead to irreparable consequences.

Video - Do-it-yourself geyser repair

Each specialist will confidently declare that a gas water heater is a dangerous device and a professional worker in this field should carry out its installation and repair services.

But it never hurts to understand what exactly can interfere with the normal functioning of the equipment. Below we present typical breakdowns and recommended actions to eliminate them on their own.

There are several reasons for this problem. The first thing to do is to check if the igniter is working properly. If it does not ignite, you must contact the gas service for help. Never try to fix the problem yourself.

Modern geysers have electronic ignition and in the event that there is no ignition, the gas supply stops - it is cut off by a valve. The corresponding indicator will notify you of this. Some situations are solved by simply replacing the batteries, as described in the instructions. If it is impossible to solve problems, we also contact the gas service.

Also, the problem may be the lack of draft in the ventilation. To check the moment data, it is necessary to bring a sheet of paper to the ventilation. If the sheet remains in one position, the thrust is not carried out.

To clean the ventilation apartment building you should contact the utility. You can also do this yourself using a metal brush that is tied to a long wire.

The next reason is the wear of the membrane. This is a rapidly deformable element, for this reason, the equipment start-up mechanisms lose their sensitivity and do not work when water is supplied. In order to check this factor, it is necessary to turn on the water to the maximum level. In the case of turning on the equipment at high pressure, the problem lies precisely in the membrane. It is possible to replace it with your own hands.

Follow the instructions below:

• first unscrew the nuts securing the water unit (2 pcs.)
• then unscrew the fastening screws (3 pcs.)
• disconnect the halves of the knot, there is a membrane inside. If it is deformed, it needs to be replaced. You can buy it in a store specializing in this equipment.

You can also see what condition the water intake filter is in. If it is clogged, clean it or replace it, depending on its condition.

The gas stove lights up and goes out

After turning on the heater and its subsequent attenuation, the problem is a bimetallic temperature sensor that protects the device from possible overheating. And also in case of failure this sensor the heater may not turn on.

In these cases, there are two outcomes of events:

1) In the first case, the burner ignites, the device works for a certain amount of time, after which it fades and does not function. After a while, when you turn it on, everything repeats. The reason is the sensitivity of the sensor. In this situation, you should contact the service to make a warranty repair.

2) In the second case, a complete or chaotic shutdown of the column occurs. The reason is insulating material sensor, or rather its wear. In this situation, you should also contact the service to make a warranty repair.

This situation occurs when the heat exchanger is clogged with scale. The device heats the heat exchanger to temperatures sufficient to evaporate residual moisture.

In the absence of water flow, scale is poorly washed out, it accumulates, and as a result, the equipment does not work properly. Sometimes cleaning the heat exchanger helps. At running case need to be replaced.

For a replacement, contact a specialist, and cleaning can be done on your own. To do this, prepare a screwdriver, a hose, wrench and paranitic lining. Purchase a descaler from the store.

Stage one. Remove the fittings and casing from the heater.

Stage two. Shut off the inlet water and turn on the hot water at a location away from the equipment.

Stage four. A hose should be put on the inlet to the heat exchanger and raised above the location of the heater. Using a funnel, carefully pour in the descaling agent, the main thing is not to rush. Then you need to leave the liquid inside for the time allotted according to the instructions.

After the time has passed, use a container to pour out the liquid. If at first the slag came out, and then the pressure resumed, then everything went well. At negative result repeat the above steps.

With such a problem, you should contact the specialists for adjustment. For self-development, you can clarify the causes of this phenomenon, there can be about two of them:

• The flow of gas with a strong pressure. There is an active ignition of the heater, as a result, the fire breaks down.
• The flow of gas is weak pressure. Air enters the burner resulting in a micro-explosion.

The gas water heater does not heat the water well

The main reason may be the poor power of gas equipment.
There are two solutions to this situation:

• stop demanding more from the equipment - do not simultaneously open hot water taps throughout the house.
• buy more powerful equipment.

Another reason could be clogged equipment. This can be checked by the color of the fire, when normal conditions he is blue. When yellow color contact the gas service.

Gas stove smells of gas when turned on

This situation is very serious. Don't do it on your own. Turn off the equipment, turn off the gas supply valve, ventilate the room and call the gas service. Arriving workers will do everything necessary to eliminate the problem.

Video - Gas column malfunctions and their elimination

For the work of any gas device must be watched very carefully. Notice all the little things and details that have changed when the unit is turned on, during its operation. This will help you identify and fix problems that have just begun in time, and possibly even prevent a major problem.

What to do if the column does not ignite?

This is the most frequently asked question, which occurs among the owners of gas equipment. Wait to panic - let's understand the situation. In fact, there can be a great many reasons for this - from the most simple and banal, which can be eliminated in 5 seconds, to very serious ones, for which you will need a specialist to deal with.

The very first thing you need to do- see if the igniter is on. If he doesn’t even think about lighting up, then you can’t do without a specialist gas service. He will competently clean the igniter jet, or maybe replace the igniter itself with a new one.

The second likely reason is you simultaneously open the faucet with cold and hot water, and the flow of cold was much more. This is what led to the extinction of the flame in the igniter.

No draft in the chimney

You try to ignite the gas, but it just won't ignite. Why? First check the draft in the chimney. It is likely that it is clogged with various debris, and the combustion products simply will not be discharged outside, but remain in the room. In this case, the built-in protective automation of the device simply does not allow it to ignite and does the right thing - it's life-threatening!

Your actions in this case are simple: open a window or window. Light a match and bring it up to the chimney. If the flame does not even make an attempt to deviate, then the chimney is not working. Just call the master to clean the pipe and everything will be in order.

Check the chimney outlet first. Perhaps one of the neighbors installed an antenna above him, so the thrust was gone. By the way, this is forbidden, as it is a potential cause of carbon monoxide poisoning.

Another one possible reason lack of traction tightly closed windows in room. Simply put - there is nowhere to take traction. This is especially true if you have plastic windows and it's cold outside. Of course, you will try to close it as tightly as possible, completely blocking the access to air. If after opening the window the column lights up, then the problem is obviously solved.

Batteries (batteries) are discharged

If your unit has an automatic ignition system, then do not skip this reason, even if you bought a column a few months ago. Enterprising manufacturers promise a year or more of work on a single charge, but in reality this is not at all the case - the elements “die” much faster.

What to do in this case: Replace the batteries with new ones and try the power button again. If the column lights up, then the problem is fixed.

How long do you hold the fire button? For the column to function properly, the button must be pressed for at least 20 seconds.! If you hold it less, then the column will go out after a while.

Weak water pressure

The column can only work at a certain water pressure in the pipes. If the pressure is low, then she will not even think to turn on.

What to do in this case: open cold water in another room. If the water also flows “sluggishly” there, then the problem is in the water supply system. You just have to wait. If the water flowed very “briskly”, then the problem is already in the unit itself.

Filters or membrane?

If the device went out after turning on, then the point here, with a high degree of probability, is in the temperature sensor responsible for overheating the column. In this case, 2 scenarios are possible:

1. The column lit up, worked for 10-15 minutes, after which it went out, and all attempts to kindle it did not lead to anything. After some time, it can be turned on again, and after 10-15 minutes the story repeats itself and again in a circle. Reason is too sensitive sensor overheating. He fixes too high temperature around the speaker and turns it off. In general, this is a factory marriage, so if you wish, you can give it for service.

Remember that this problem can only appear in the middle of summer, when it's hot, or in winter, when all the windows are closed. You'll be lucky if your purchase's warranty hasn't expired by then. Otherwise, the repair will have to pay out of pocket.

1. Unit shutdowns do not have a pattern - it may not turn on, then work properly, and then turn off again. If this situation is familiar to you, then the cause may be a frayed sheath of the sensor conductor. The bare part closes to the case and turns on safety valve. Who to contact in this case? To a service center or to the manufacturer of the model. The gasmen will not help you here, as this is not their part. And with your own hands, you are unlikely to be able to fix anything.

How to remove scale from a column

This problem occurs frequently. Its consequence is weak pressure warm water from the tap.

What to do in this case: you need to clean the heat exchanger (its replacement is carried out in very neglected states). And if you yourself cannot carry out the replacement, then cleaning it is quite up to you.

First, let's look at the reasons why scale occurs. Everything is very simple - the water in our pipes flows very hard, with large quantity lime. When the water temperature reaches 80˚С, it settles on the walls of the heat exchanger. Conclusion - try to use very hot water as little as possible - above 80 ° C. After all, even greasy dishes can be washed at 45 ° C.

Many people leave the column igniter on, as it is convenient - you do not need to constantly turn it on. However, after 1 hour the temperature of the water in the heat exchanger will reach 85˚C and higher. Therefore, we advise you to always turn off the column after use.

If you still need to clean it, then you have to arm yourself the following equipment:

• Open-end wrenches;
• Screwdrivers;
• rubber hose;
• Paronite gaskets;
• Descalers (e.g. acetic acid).

Step 1. Shut off the water and open one hot water - at the point that is closest to the column.

Step 2. Remove all fittings and cover from the column.

Step 3. Disconnect the hot water hose from the radiator and lay it aside. Wait until all the water has drained.

Step 4. Put a hose on the heat exchanger and very carefully start pouring an acid solution or other agent through it. Don't pour a large number of immediately, otherwise a very stormy chemical reaction. Leave for at least 2 hours.

Step 5. Place a basin or other container under the tap and open it. If there is a lot of sludge in the water and the pressure is restored, then the problem is solved. If not, we recommend doing the procedure again.

For more information about cleaning the heat exchanger, you can watch the video:

The column turns on with pops

There are 2 reasons for this phenomenon:

1. Too much gas pressure. As a result, the burner ignites too actively and the flame breaks off with a corresponding sound.
2. Too little gas pressure. air enters the burner and the resulting gas-air mixture explodes, producing mini cotton.

What to do in this case: call the gas service worker to clean the burner. Do not do this procedure yourself!

The column heats the water incorrectly

You ordered hot water, but the water is barely warm? Check the power of the unit you have chosen - it is quite possible that according to its technical specifications the model is simply not capable of more.

Second a possible solution is to stop opening several taps at the same time (kitchen, bath and shower).

Third option- The burner is clogged. Checking this is easy - the color of the flame instead of the correct blue has become yellow. Call a specialist: 1 hour of work and the column will again work with a bang.

Smells like gas when turned on

This is the most dangerous scenario. It means that some connection is leaking. If you feel even the slightest smell of gas when you turn on the device, then immediately shut off the gas supply pipe, turn off the column, ventilate the room and call the brigade (104).

In no case do not try to figure out the reason yourself!

Geyser is flowing- how to solve the problem?

One of the most frightening malfunctions: after its manifestation, you immediately want to rush to the store for a new radiator (it is he who flows). However, its cost will make you think - can you do it yourself? And you will be right (if, of course, you have at least basic soldering skills).

So, we need:

• 2 screwdrivers (flat and Phillips);
• Open-end wrenches;
• Vacuum cleaner;
• Sandpaper;
• 100 W soldering iron - less is not recommended.
• Solder;
• Solvent (acetone or alcohol);
• Rosin - it can be replaced with a regular aspirin tablet.

Disassemble the column and find the damaged area of ​​the radiator. Most often this is a pipe on the outside of the heat exchanger. After detection, drain the water from the radiator of the device (open the hot water tap and unscrew the nut from the unit pipe that supplies water to the column - the water will drain itself due to the difference in levels. “Blow out” the rest with a vacuum cleaner).

Clean the place of work with sandpaper, and then wipe it with a solvent or any alcohol-containing liquid. This will degrease the pipe material. Solder, by the way, can be absolutely anything, and rosin (or aspirin) is a flux.

When the damaged area is already covered with solder, then increase the thickness of the layer to 2 mm. If you see a "green" place, then this indicates one thing - there is also a tiny crack that needs to be soldered.

Remember! For any doubt about own forces It is better to leave repairs to qualified personnel!

Prevention of geyser problems

We will give you some tips that will not only extend the life of the column, but also help to avoid many of the problems described above.

• In the room where the column is installed, there must always be an air supply. A window, a window leaf during the operation of the device should be open even in winter.
• Never! Do not mix cold and hot water. In general, this is considered a gross error in the operation of the column, which leads to the formation of scale and a reduction in operating time.
• Choose gas hoses with a length of less than 3 meters. Otherwise, the gas pressure becomes very small, which can also cause interruptions in operation.

We wish you trouble-free operation of your geyser!

Such a complex device as a geyser serves quite long time, maintenance and operation is carried out according to the instructions attached to this unit. But all things deteriorate and sometimes minor or major repairs of gas water heaters or their prevention are necessary. As well as the replacement of some components of the gas column.

Machine description

The internal structure of flow-type gas water heaters is the same and almost does not differ at different manufacturers. The main difference may be in additional options(display, automatic gas ignition, second temperature sensor, etc.), during appearance device or structure.

A heat exchanger is installed inside - a finned copper tube through which the water flow moves. The burner standing under the heat exchanger heats the tube and the water passing inside it heats up. With a small pressure of water or its absence, the incoming flow is blocked by a valve (curtain), to which a spark ignition switch is attached. This is for fire safety.

Call the master or repair it yourself

We call the master

To repair a faulty geyser or prevent a gas leak (if you smell), you need to call a gas geyser repairman. But if you decide to call the employees of Gorgaz, then do not think that they will come right away, sometimes they refuse to come, arguing that the repair should be carried out by the company (or store) that installed the gas water heater.

Attention! Use only companies that have the necessary certifications to work with this equipment.

Now divorced a lot of "left" firms and house calls of workers of such organizations bring a number of other problems. Many craftsmen, seeing your incompetence in this area, find non-existent malfunctions of the geyser or deliberately inflate prices.

Do-it-yourself geyser repair

To improve public safety, it is prescribed that malfunctions associated with gas equipment eliminated by employees of the relevant service. But there are some problems that you can fix yourself. If you know how to hold the tool in your hands, you can repair the gas column with your own hands.

It's not very difficult if you know typical problems these water heaters. Below we will talk about the most common of them and show you how to fix this or that breakdown. And let's start with setting up the unit.

Burner flame height adjustment - the closer to the maximum, the hot water.
Adjusting the water flow - the closer to the maximum, the greater the flow, therefore, the water is colder.
Winter / Summer - the mode of using the column in different times of the year. More power in winter than in summer.

Not all craftsmen know how to properly set up a geyser and simply do not do it, leaving it as it is (by default). But we do not recommend leaving the factory settings and adjusting yourself.

Temperature setting

• Set the gas and water supply knob on the heater to minimum.
• Open the gas and water supply valves on the pipelines.
• Open the hot water tap and adjust the water pressure you need using the knob on the gas water heater.
• Wait 1-2 minutes and take the temperature. Using the gas supply knob on the column, increase the flame, thereby raising the water temperature to the desired one.
• When the water temperature is comfortable, you can leave all adjustments alone and use the water.

In the future, you can adjust the temperature with another knob (supply of heated water).

Pressure setting

When adjusting the column, sometimes unpleasant moments arise. A new column either turns on at a very low pressure, or does not want to start at all. It depends on the increased or reduced pressure of water in the pipeline and is eliminated in the following ways.

With our water quality, heat exchangers in gas water heaters become clogged with scale quite quickly and very much, which reduces their thermal conductivity and increases gas consumption.

The longest, in time, process is cleaning the main tube(radiator) from deposits arising from heating tap water. If you turn the gas knob to the end, and the outgoing water is barely warm, then this indicates a clogged heat exchanger normal scale which does not transfer heat well.

This happens quite often if the geyser is without auto-ignition (with an igniter). Also, scale is formed if you set the water heating temperature too high. The unit overheats, the tube (radiator) heats up to 80-850, which contributes to the rapid (a little over an hour) scale formation. Isn't it better to just turn off the column in time? Then there will be no problems, because 40-600 is enough for all washing and washing processes.

Before starting work on the heat exchanger, check the inlet cock or valve. Maybe the whole reason is in their clogging. But if they are serviceable, it is necessary to get rid of deposits in the tube.

There are two ways to solve the problem with scale. We will consider both options.

The Cillit KalkEx cleaning system does the job pretty well. With its help, you can quickly clean any boilers from scale. Unfortunately, it is not very accessible to ordinary users of gas water heaters.

This is an expensive method using a special device(Cillit KalkEx) and a set of special preparations for flushing. Your column does not even need to be removed from the wall. Just need to disconnect the water hoses for water (inlet/outlet).

The cleaning device is connected to the column, and it closed loop(in a circle) drives heated reagents. Scale under their action decomposes, is washed out and merges.

Manual

Cheap but long and laborious process . For its implementation, it is necessary to disassemble the water heater almost completely and then rinse it manually.

The following materials and tools will help us with this:

• wrenches (set);
• screwdrivers (phillips and regular);
• paronite gaskets (set);
• rubber hose;
• vinegar essence or antiscale agent.

Disassembly of the gas apparatus

To remove the heat exchanger proceed as follows:

• block access first cold water;
• then we remove the external elements that prevent disassembly (knobs of switches, regulators);
• remove the cover, and to do this, unscrew the screws located on back wall unit, lift and remove the cover;
• open the "hot" tap;
• unscrew the supply tube from the heat exchanger and move it away;

Flushing the system

After the water has completely drained, we put the hose on the heat exchanger tube and raise it above the level of the column. Slowly pour the solution we prepared into the hose and leave the column for 4-6 hours.

Next, you need to slightly open the water supply tap and observe the water that will come out of the column, if you saw a lot of scale, then our work was not in vain - we got rid of it. If there is no scale in the outgoing water, then we repeat the whole process again.

The gas stove does not ignite

1. A water heater failure can occur for many reasons. We list the most likely ones:
2. The most simple reason this trouble is the lack of normal draft in the chimney. If the chimney is clogged and there is no “draught” in it, then the column may not ignite.
3. To check for a malfunction, you can bring a piece of newspaper, a napkin, or a lit match to the chimney. If they tremble, then the thrust is in order. Otherwise, you will need to clean the chimney.
4. If the device (only in units with auto-ignition from batteries or electrical network) does not ignite, then the fault is the discharge of the batteries or a malfunction of the wires, the igniter unit. Eliminated by inserting batteries or checking the electric ignition system.

Failure of the igniter system may occur due to poor pressure water. Open any faucet with cold water and check the pressure, if it is weak, then you can call the housing office and find out what the problem is.

If the column does not ignite when water is supplied or turns on only at very high pressure, then the problem is most likely in the membrane, which, due to wear, does not respond well to the water passing through it. In this case, it must be replaced.

The geyser spontaneously turns off

A temperature sensor is installed on each geyser, which ensures that the geyser does not overheat in case of failure column may spontaneously turn off during operation. It usually looks like this:

After normal operation, for some time, the heater "stalls" for 20 minutes. After this time, it can be turned on for the same period of time. The malfunction, as a rule, is seasonal and appears only in summer or winter with the windows closed.

The device turns off when it wants to and then does not light up. This can happen when the sensor wire is shorted to the ground. Check the wires to make sure they are intact and well insulated.

In order to check the sensor itself for operability, two contacts should be removed from it and short-circuited with a needle, a paper clip, a piece of tin. If the gas appliance turns on and works, the sensor must be changed.

Water heater is leaking

If you see similar spots on your column, then be sure that it is leaking and needs repair.

This malfunction can occur mainly in geysers that have been operating for a long time. The two main reasons for leakage are:

Radiator leaked.

Cracked pipes (bends) or gaskets in the joints.
Replacing a radiator or taps is quite expensive. Therefore, there is a reason to repair the gas column on your own. For repair you need:

• screwdrivers (cross and regular);
• wrenches (set);
• solder with rosin;
• vacuum cleaner;
• solvent;
• "skin".

Hole sealing

Due to harsh working conditions, the radiator or taps can burn out and holes appear on them. If you have determined where the leak is, then you can repair a small hole with an ordinary soldering iron.

Preparing a geyser for repair

• Drain all liquid from the system - open only the hot water tap, unscrew the nut on the cold water inlet pipe, and most of the water will flow out;
• Remove the radiator completely;
• Examine the entire tube. - if you see "green" - clean and inspect these places for cracks.

When you find leaks, you need to do the following:

• clean the holes found with a “sandpaper” and immediately wipe with a cloth with a solvent (this will remove the remnants of fat, soot and dirt);
• using rosin with solder, tin this place with a 100-watt sanding iron (for lack of rosin, use aspirin);
• rub the crack or hole with solder, and after it cools, add more tin (the layer should be 1-2 mm).

Attention! In some cases, with holes of about 5 cm, the craftsmen apply a “temporary” overlay from a plate of copper or aluminum, securing it with thick wire or metal tape. But as a rule, such a “temporary” solution remains for a long time. We recommend replacing the radiator completely and forget about its leaks.

Faulty gaskets and tubes

Replacing flexible hoses of this type does not require special skills, it can be done by anyone with a wrench.

Very often, leaks form at the points where the taps are connected to the heater from the outside or to the internal nodes of the dispenser. All connections are made by "American" with gaskets inside.

Due to constant heating/cooling, the rubberized liners either melt or lose their properties and harden. Cracks appear in them, through which water flows.
If you notice a gas column leak in such connections, then replace the gaskets. Using a wrench (mainly 24), unscrew the nut and replace.

It also happens that the flanges on the tubes crack over time - in this case, you need to replace the entire tube.

The geyser turns on with pops

Be sure to change the batteries in the gas column in time, because if they are dead, your column will start to make pops when turned on. Also, due to dead batteries, the column may spontaneously turn off.

These sounds when turned on and during operation indicate the following points:

• due to the low gas pressure, a little air got into the system (into the burner), which gave rise to a microexplosion;
• the flame breaks down due to the high pressure of the gas;
• jet blockage;
• small ventilation draft;
• the batteries have run out.

On your own, you can only eliminate the malfunctions described in the last two paragraphs.

The gas water heater does not heat the water well

This can happen for several reasons.

• The simplest reason is incorrectly selected gas column. You saved money and bought a low wattage heater unable to meet your hot water needs.
• The second reason is the low gas pressure in the pipes (in the apartment). Call the gasman to check the system.
• The third reason is the usual blockage (jet, filters, scale, hoses, etc.), some of which are described above. You can check this by the color of the fire, which changes from time to time. This is also evidenced by the presence of soot.

You can only adjust the temperature and clean the column yourself.

Remember! Self adjustment geyser and troubleshooting requires special care. With poor-quality work, not only you, but also completely innocent people can suffer. At the slightest lack of self-confidence, it is worth contacting the professionals of the gas service.
