Water heater buttons - meanings and solutions to problems that have arisen with them. Water heater buttons - meanings and solutions to problems that have arisen with them. Checking electrical elements and heating elements

If there is a need to purchase a high-quality water heater for your home or summer cottage, then you should pay attention to models from Polaris. This company represents a wide range of devices, among which you can easily choose the right option.

Specifications

Devices of this brand are available with different, but convenient controls. Some models are equipped with mechanical control, while others are electronic and even differ in the presence of a display that displays all the necessary information.

Also among the technical characteristics of a particular model, you should pay attention to the presence of a thermostat and power levels.

It is worth noting that all Polaris models have reliable protection, which is guaranteed to ensure uninterrupted and durable operation of the water heater. All devices must have protection against overheating and automatic shutdown. That is, in the event that the device becomes very hot, the work will stop automatically, preventing the water heater from spoiling.

The magnesium anode helps prevent corrosion of the inner walls of the tank, so it will last much longer.

In addition, the models of this brand are produced with a dry heating element, which is very reliable. The fact is that the heating element of the device is under reliable protection, is located in a sealed flask and does not come into direct contact with water.

Advantages and disadvantages

Each model of boilers from Polaris has many advantages, which should be discussed in more detail.

The devices of this company are reliable, economical, durable and the reviews about them are the most positive. Each of them is equipped with convenient and understandable controls. In addition, quite a budget price of models is also their significant advantage.
The devices from Polaris are characterized by high power, thanks to which they allow you to get hot water in a matter of minutes. The assortment regarding the volume of tanks is also pleasantly pleasing. You can choose any size that suits your family.
Many consumers are attracted by the fact that devices from this brand are fully equipped. That is, you do not have to additionally buy wires, a shower, etc., everything is already included in the kit.
In addition, the advantages include the original and stylish design of the devices, thanks to which they look very aesthetically pleasing in any interior, in perfect harmony with other modern appliances.

Despite all the advantages, water heaters from Polaris still have some disadvantages.

Consumers who already use devices of this brand note that some models are too bulky and heavy. Of course, this is a minus, especially if the house has thin walls. It is worth considering this fact during installation. If there is no confidence in the reliability of the walls, then you will need to take care of additional security and a fastening system.

In addition, among the shortcomings, consumers note the high price of some models. Therefore, before laying out a large amount for a particular model, you need to find out what its advantage is over more budget options.

More budget options, as a rule, differ in a tank with thin walls, which, of course, is a disadvantage. Such models will not be able to last too long and there is a risk that the device will soon begin to leak. Check all the nuances before buying and be sure to purchase a model with a guarantee.

Flow models often have such a disadvantage as servicing only one point. This is not very convenient, especially if hot water is needed both in the bathroom and in the kitchen. In addition, such models can work properly and smoothly if the house has good water pressure. Otherwise, interruptions in work will begin.

Kinds

Polaris water heaters come in a variety of types and sizes. There is a flowing water heater, and there is storage. Tank sizes also vary. It can be 10, 30, 50, 80, 100 liters and even 150.

Storage water heaters from this company are produced in volumes from 10 to 150 liters. As a rule, such models perfectly withstand pressure up to eight atmospheres. The design of such devices also has its own distinctive features. For example, storage models can be easily connected to a conventional outlet, which is very practical.

Many storage models from Polaris have the ability to connect to several points at once, which allows you to install one water heater in the house for all water intakes.

As for the time it takes to heat up, it all depends on the model and the volume of the tank. Usually, the first heating after installing the water heater takes at least half an hour. After that, the heating element will turn on when the water temperature drops. Thus, there will always be hot water in the tap of your house. This method of heating also helps to save energy.

In addition, storage tanks are equipped with high-quality heating elements and have excellent thermal insulation, thanks to which they heat water as quickly as possible and keep it hot for a long time.

When choosing a storage model, it is worth considering the fact that you need a separate place for its installation. If you need a water heater only for washing your face or washing dishes, then a tank of 10-15 liters is the best option. For regular showering, the volume should be at least 30 liters, on average - 50. And for those who are used to taking a bath often, it is worth buying boilers with a volume of 80 liters or more.

Another type of water heater is a flow. Its main difference lies in the fact that it is able to heat water to the desired temperature in almost a matter of seconds. Cold water, before getting into the tap, passes through the heating element and, immediately heated, pours out of the shower or tap.

Flow models are divided into two types: pressure and non-pressure. The first option is in great demand. Such models are mounted in the risers themselves, which saves space in any room. Their only drawback is that they are much more expensive than non-pressure ones.

Flowing water heaters, as a rule, are distinguished by their compactness. Most often they are installed in the kitchen.

Range overview

All models from this company attract with their design at first sight. For example, there are flat models that look great in the interior, becoming its bright detail. You can also choose a compact version, for example, with a volume of 15-20 liters.

Series Models Gamma are in high demand among modern consumers, and for good reason. The tank of such devices is made of stainless steel, the case is made in a laconic design. Ten is also made of stainless steel. The control of such devices is very practical - mechanical. Besides, boilers are reliably protected from corrosion. Models of this series are considered one of the most hardy and durable.

Series Vega is also represented by models of various sizes. All appliances are equipped with stainless steel tanks and powerful heating elements. Among the additional functions, it is worth noting the fast heating function, which allows you to get the desired amount of hot water as quickly as possible. It is easy to manage such devices, especially since they are equipped with a modern digital display that displays all the necessary information.
Aqua- Another popular series of storage boilers from Polaris. The tank is also made of high-quality stainless steel, but the heating element in this series is copper. All devices, regardless of volume, are equipped with electronic control, special improved thermal insulation and powerful protection against overheating and various kinds of leaks.

Series of storage water heaters Omega has all the qualities that were mentioned above. Separately, it is worth noting that the models are equipped with modern controls and an LED display, which makes it much more convenient to make settings. All water heaters are equipped with a magnesium anode, reliable protection against overheating and are characterized by high thermal insulation.
As for flow devices, pay attention to the series Orion. Models of this series are equipped with a copper heating element, so that the water heats up quickly and efficiently. It comes with a handy shower head.
Mercury- Another compact instantaneous water heater. The heating element of the device is quartz. The model is equipped with a special indicator, thanks to which it will be possible to know whether there is enough hot water. In addition, with this model it will be easy to choose the heating temperature yourself. A shower head is also included.

Trouble-shooting

It often happens that due to prolonged or improper operation, the boiler fails. Accordingly, the device needs to be repaired. Before calling a specialist, it is worth determining the cause of the problem, because often many problems can be fixed by hand. But someone can safely remove the control panel, disassemble the device and fix the problem, while someone does not even know how the digital temperature indicator is replaced.

Typically, owners of water heaters face the following problems:

the device has stopped heating water or heats it poorly;
the tank is leaking;
water does not enter the tank well;
there was a strange sound during operation.

An instruction manual is included with each device. As a rule, the most common problems are listed there, which can be easily solved by following the step-by-step instructions.

Electric water heater Polaris FDRS 80V. In operation for over five years. The heating element has been changed several times. This time the problem is somewhat different - the thermocouple does not correctly determine the temperature, as a result, the heating element turns off, assuming that the set temperature has been reached, although in reality the liquid is barely warm. He took out a thermocouple, applied cold objects to it, the reaction is normal, the temperature immediately drops. But, as soon as I put it in place, it jumps in the heating element and rises abruptly. What do you think it could be?

Most often this occurs when there is a malfunction in the electronics, or as a result of a breakdown of the heating element on the skin. I believe that in your situation, this is the second option. Electricity through the heating element penetrating the shell affects the electronics by means of a sensor (thermocouple).

Accumulative water heater Polaris 30 liters. The heating element has broken. Carried out the disassembly, got it, wrote the model. I had such a question: is there any point in replacing the heating element or is it better to buy a new device right away? What else needs to be replaced besides the heating element? As far as I understand, it worked the protection system? The sound was very loud, although the machines did not turn off.

Most likely the unit needs to be replaced.

Electric water heater Polaris Gamma IMF 50V. When hot water is turned on, cold water instantly sets in, and the temperature drops rapidly, only half a bucket of hot water is drawn. Otherwise, everything functions normally, the connection is correct.

Presumably a defective check valve.

Installed electric water heater Polaris 50 liters. Used only a few times a year when the central hot water supply was turned off. For three years it worked properly, but this year it stopped heating. The monitor is on, the water is running, but it is cold. It turns out that for all the time that he has been with us, he has worked for only a month and a half. What do you think happened? Does it make sense to renovate?

Maybe the heating element burned out. It won't cost you much to replace it. For a heating element, it is much more serious to heat the temperature from zero than to maintain a constant temperature. In general, these elements are considered consumables, because they burn out quite often. More precisely, only a specialist can tell you after a visual inspection, because there may be other reasons.

Installed water heater Polaris Aqua IMF 100V, in operation for about three years. At the moment, it is connected to the mains, the lamp is on, but the water is not heated. Can any of you suggest what might have happened?

To accurately determine the breakdown, you will need a visual inspection of the device, presumably, the heating element has broken down, or as an option, the reason may be in the thermostat or faulty contacts and connections.

Electric water heater Polaris 80 liters in operation. Over the past few years, I noticed that the heating indicator lamp is on all the time, so the heating element does not turn off, and the body of the device began to heat up, how dangerous can this be? You have to unplug it from time to time. I reset the heating temperature using a thermal relay - there was no result.

Overheating of EWH is dangerous. I think the thermostat is the problem and needs to be replaced.

I start the storage water heater Polaris Ultra IMF 50 V, it heats up to a certain temperature and turns off completely. Previously, everything was fine, it heated up to 70 degrees, and now it turns off already at 44. After some time, I connect it to the mains - again the same situation (I replaced only the plug, the device has been in operation for three years).

Most likely a broken thermostat. In addition, if you use hard water, you should clean it from scale and plaque.

Malfunction of the Polaris FDRS RN 80 VR boiler. It started leaking at the bottom. Not from the filling, but from the bottom cover. Is it repairable, if so, what needs to be done?

First of all, you should find out the exact location of the leak and fix it. If the problem is in the pipes and connecting points, then they need to be replaced, but if it's in the tank, then most often this cannot be repaired.

About a year ago, we purchased a Polaris water heater for 50 liters, at the moment the following malfunction has appeared. It was full and we did not use it while there was a centralized hot water supply. Cracks formed on the shell, and it began to leak in the lower part under the protective cover. The protective shutdown device is triggered, and as a result, heating does not occur, and the heating sensors do not light up either. What to do? Is it possible to solve this problem on my own or do I need to call the wizard?

Of course, it is better to call the master, because the device will need to be disassembled to determine the exact location of the leak, in addition, other possible breakdowns that will be discovered only after inspection cannot be ruled out.

Water heater FDRS 30V. I fill it with cold water, set the temperature in the middle of the scale, it warms up and turns off, as expected. Then I analyze the water, drain a few liters, turn on the heating and heat it to the limit, boiling water comes out of the mixer. I completely drain the liquid, again I collect cold water, start heating, everything works. What is the fault?

Without a visual inspection, it’s not enough just to say what exactly the problem is, you need to check the thermostat, temperature controller, and so on. Diagnostics is required to accurately determine the breakdown.

On the Polaris boiler of 80 liters, the machine turns off, during disassembly it revealed that the heating element is heated directly. I removed the residual current device on the wire, the machine still turns off. It turns out that the problem is in the thermal protection on the heating element?

As an option, the inoperability of thermal protection, or something else, needs to be checked, without an external examination and diagnostics it is impossible to say.

Polaris FD50V. Won't start, no display. Electricity is coming in. Maybe the thermal protector has kicked in? Can't find the off key.

In order to get to the thermal protection key, you will need to remove the tank lid, after de-energizing the device. At the same time, you must figure out what contributed to the thermal protection, maybe a breakdown of the thermostat or heating element, or something else. And it is possible that thermal protection has nothing to do with it. You should contact a specialist in order for him to diagnose and repair.

We use an electric water heater Polaris 100 liters, I can’t figure out what the problem is. For some reason, liquid is not drawn in, given that all the taps are open, the hot valve on the riser is closed. On cold water, a valve is installed and a non-return valve is installed at the bottom. When I open the hall. water and hot in the tap, then water flows from there, this indicates that the device is full. But when the hot water is closed after 20 minutes, I unscrew it again, then there is no water. Could this be due to air in the boiler?

Of course, air can accumulate in the device. You should check the check valve for serviceability, and make sure that the connection is correct.

Water heater Polaris Mercury IDF 80V, we have been using it for about a year. A few days ago, the fluid stopped heating, although the indicator lights are on. I cleaned the heating element, visually found no defects (cracks, swelling), no, the problem did not disappear. Please advise what could be the reason and how to fix it?

In order to completely eliminate the breakdown of the heating element, it is necessary to measure the resistance on it, in addition, a malfunction could occur in the thermostat, it also needs to be checked, but other breakdowns cannot be ruled out.

There is a Polaris FDRS RN 30 water heater. Liquid flows in the area of \u200b\u200bthe gasket on the device itself, located on the water supply pipe. What needs to be done?

Change gasket.

The water heater Polaris 50 liters stopped heating to the shutdown temperature, now the indication is on all the time, and the water is almost not heated. How to solve this problem?

As an option, the cause could be a breakdown of the heating element, a large amount of scale could have formed there, maybe the thermostat had broken. It is possible to name the cause more accurately only after a visual inspection.

Valve damage occurred on our Ultra IMF 80V canister. I changed it, three days later it broke again, I had to buy another one - the result is the same. What is the reason, who knows? Valve me specialist. He said that the quality is not very good.

How does valve failure manifest itself? Does he release pressure all the time? If this is indeed the case, then there are only two possible solutions to the problem. The first is if the system pressure is too high. If this is indeed the case, then a water pressure reducer should be installed. Second, the valve was too tight during installation. The valve should turn 4 turns. Otherwise, the plastic elements that make up the valve will go down, and liquid will ooze through the valve in the opposite direction into the cold water riser (the cold pipe will heat up).

Storage water heater Polaris Vega IMF 50H - after a few minutes after starting, thermal protection is activated, weak heating. Tell me, what's the matter?

If there is practically no scale in the boiler, and the heating element is not overgrown with it, then the protective thermostat should be replaced - it should work at temperatures above 95 degrees.

Interested in this question, why does hot water from a 50-liter Polaris boiler dilute very quickly? Previously, I could take two baths, but now only one. The regulator is set to the maximum position.

The problem is most likely either in the thermostat, or in a large amount of scale on the heating element. It is she who prevents the temperature controller sensor, which is inserted into the heating element, to correctly track the temperature. And most likely the liquid is not heated to the end. In other words, the hottest water is located at the top, it is consumed quickly, and the lower part has not warmed up yet. If there is practically no scale on the tubular element, then the thermostat is to blame - it turns on too early.

In operation, a Polaris water heater for 80 liters. There is a heating indication, the device is on, the heating element is functioning, but the device does not heat the water, more precisely, it heats up, but only up to 20 degrees. What to do, give advice?

Most likely, you have a leak, the liquid leaves the GW riser. Valves need to be checked.

Accumulative boiler Polaris Aqua IMF 50V - I can not turn on the keys at the bottom of the tank. Residual current device (RCD) is working properly. What could happen? We've only been using it for four weeks.

It could have knocked out protection, or something else worse, a malfunction of the tubular element or thermal relay.

Electric water heater FDRS 50V with electronic monitor. Tell me, please, for what reason can the temperature be displayed incorrectly, the water runs hot, and only 15 degrees is displayed on the monitor?

Presumably a failure of the electronic control board or sensor.

Polaris 80 liters, began to heat up for a long time. In use for about a year. It heats up to 70 degrees during the night, and earlier it took 40 minutes. What could have caused this?

The breakdown is obvious. There is one of two options - a heating element or a thermostat.

In everyday life, we have been using the FDRS 50H water heater for quite some time. For the past two months, a noise has been distinctly heard several times, as when a kettle is being heated. Just a few days ago, it began to leak in the area of \u200b\u200bthe fastenings of the lower protective cover, and the liquid is rusty. What tell me?

Noise is not a problem, the heating element is clogged with scale. But the leak is already more serious. Sounds like a depressurization of the tank, but to understand if this is actually the case, you will need to remove the cap and check.

What are the reasons why hot water does not come out of the Polaris water heater?

The coarse filter at the inlet to the device is clogged - If you have old-style pipes or too contaminated liquid runs, then the strainer becomes clogged after a while. It must be disassembled and cleaned or replaced with a new one. To do this, you need to remove the cap from the flask with a key and get the mesh. Another problem can be solved by installing an additional filter.

Relief valve stuck - This can occur as a result of clogging. It should be disassembled and move the stem. Due to the fact that it is connected without locking devices, it is first necessary to drain all the water.

Lack of cold water in the faucet - Even in the case of a completely filled device, if there is no pressure in the plumbing system, hot water will not flow, because it is taken from the top of the tank and moves due to pressure. In order to check, you need to open the cold water supply valve, and if necessary, call the utility service.

Breakdown or incorrectly adjusted pressure reducer - The storage boiler gives the same pressure as it receives at the inlet. In cases where there is pressure in the tap, and the hot liquid does not flow well, the pressure reducer should be checked and, if necessary, adjusted or replaced with a new one.

The formation of a large amount of scale in the tank - If there is an open-type tubular element in the Polaris water heater, then it must be cleaned in a timely manner. If you have not carried out preventive work for a long time (more than a year), salt deposition blocks the opening through which liquid enters. You should remove the cover, disconnect all wiring, remove the heating element. You can clean it by washing in a solution of citric acid, it is also necessary to rinse the inside of the tank. For faster cleaning, it is recommended to install an anode.

A breakdown has occurred or one of the inlet or outlet taps from the device does not open - The pipes are clogged. They could clog due to poor water quality. Most often, this occurs in places of bends. It is recommended to change the pipes to polypropylene. The mesh on the "nose" of the crane could become clogged. In such a situation, the pressure will be poor, both when cold water is turned on, and when hot water is turned on. It is removed and cleaned or changed to another. Before carrying out repairs on your own, do not forget to turn off the water inlet valve and disconnect the device from the electrical network. If you yourself could not solve the problem, then it is recommended to call the wizard.

Every summer, public utilities prepare for the next autumn-winter season and turn off hot water for a while.

A water heater becomes a real salvation for a city dweller for the period of planned work: it is enough to turn off the hot water supply valve and turn on the boiler so that hot water flows from the tap in a couple of hours.

However, any technique can fail, and a water heater is no exception. Often, when trying to start the boiler again, the user encounters an unexpected problem - the appliance does not turn on when the power button / buttons are pressed.

There may be several reasons for this problem, and all of them can be fixed by hand without calling the wizard.

To begin with, let's clarify what controls can be on the boiler, and what functions they perform.

Buttons on the body of the Termex water heater

As a rule, the following buttons and switches are present on the panel of water heaters (Termex, Ariston, Electrolux, etc.) with mechanical control:

Mode I - inclusion of the first heating element;
Mode II - switching on the second heating element;
Temperature regulator - when the thermostat knob is turned clockwise, the temperature rises to +75 degrees;
RCD button (residual current device) - works automatically when a current leakage occurs on the boiler body.

On the panel of modern models of Ariston storage heaters, you can also find additional buttons:

Eco - when pressed, the stagnant water purification/disinfection system starts. If you leave the ECO button on the water heater on, after a certain time (1-2 weeks), the disinfection system will automatically start once a month for preventive purposes;
FAST - button for turning on the fast heating system. By default, the boiler operates at the standard power level. Turning on the Fast button on the Ariston water heater starts an additional heating element, which speeds up the process of heating water.

Answers to frequently asked questions about the Termex water heater buttons

All storage water heaters (boilers) work on the same principle, and have a similar device.

This is how the wiring diagram of the most common Termex electric water heater with mechanical control looks like:

As can be seen from the diagram, there is nothing complicated in the device device.

The operation of two heating elements is regulated by a simple control panel, on which there are devices for monitoring and controlling heating.
Thermostats installed inside the flask allow you to smoothly adjust the temperature in the range from +7 to +75 degrees.
When the water in the storage tank cools down, the heating elements turn on again.

What to do if the Termex water heater does not turn on?

First you need to establish the cause of the problem. As practice shows, there may be several of them.

Here are the most common:

The socket is faulty, there is no voltage in the 220 V network. To check this, it is enough to connect any other working electrical device to the socket;
The integrity of the power wires is broken, there is no contact at the terminals of the heating element;
The on/off button itself failed. In this case, it will help to solve the problem replacement of the ON/OFF buttons on the water heater;
Worked water heater thermal protection button by breaking the electrical circuit. Thermal protection prevents overheating of water if for some reason the thermostat does not work. To start the boiler, you need to press the hidden thermal protection button. It is located directly on the thermostat block;
The residual current device (RCD) has tripped. With a single operation of the RCD, you can reset the emergency shutdown button of the water heater by pressing the red switch located on the device itself. If a repeated shutdown occurs, this indicates the presence of serious defects and the need for repair of the electrical appliance.

In rare cases, the problem may be a malfunction of the RCD itself. However, more often protection is triggered when the integrity of the heating elements is violated.

You can check the performance of the heating elements using a tester (measuring resistance). A damaged heating element cannot be repaired, but you can always purchase a new heating element and replace it.

Buy electronics for water heaters

Many users sooner or later face a breakdown or deterioration of household appliances. And the question immediately arises: "Where to buy electronics for water heaters in St. Petersburg?". It is best to turn to specialists, because we can talk about such components as:

Power unit (provides voltage supply).
Control module.
Display.
Temperature controller.
Residual current device.

An important advantage of good specialized stores is an extensive catalog of electronics for water heaters. A large number of various positions allows you to correctly and quickly select the spare part you need. Experienced staff will help you decide on a purchase, offer an alternative option or select a universal model.

High-quality water heater electronics, the price of which is acceptable to the consumer, can always be found at Ter-Market. Call us and we will solve your problem!

Situations when the water heater has stopped turning on are not uncommon and are always unpleasant. You can try to fix the breakdown, but first you need to figure out the reasons.

So, in front of you is an outwardly serviceable boiler, but it does not heat water, and no lights, sensors or displays work. You can determine why the water heater does not turn on only by disassembling it. But before that, you should still check the presence of current in the network - the wire may be damaged, the socket or plug may fail.

Naturally, in this case, the water heater will not work, although the device itself will not need to be repaired. Just plug in any other serviceable device and you will see if the outlet works. Emergency operation on the panel cannot be ruled out - if the water heater is used simultaneously with other powerful appliances in an apartment where the wiring is not designed for such a load.

Checking electrical elements and heating elements

If everything is in order with the supply of electricity to the device, but the Ariston water heater does not turn on, then the tank is de-energized, and all the water is drained. After that, you need to dismantle the housing cover - under it are wires, thermostats and boards.

Then we use a tester - with its help we check the supply of electricity to the terminals of the heating elements. It is quite possible that the integrity of the power wires is broken, or there is no contact between the wire and the terminal on the heating element. The tester is also used to check the performance of the heating elements themselves, because they can burn out or pierce the case.

If the spiral inside the heating element fails, the boiler will not turn on, since it will not be able to heat the water. It will also not work with a breakdown on the case, because immediately after switching on, the residual current device (RCD) will work.

Keep in mind that a burned-out heating element cannot be repaired - only replaced, and if you are in doubt about choosing a suitable heating element, it is better to contact the repair technician. They will select a heating element that matches the brand, power and dimensions, and you do not have to deal with the dismantling of a heavy tank.

Turning off the thermal protection

If the problem is not in the heating element, but the Termex water heater does not turn on, then the electrical circuit may have opened due to thermal protection. Thermal protection is an essential element of a water heater; it does not allow water to overheat above a critical mark of 90 ° C. Thermal protection is triggered due to the fact that:

The thermal protection button returns to its working position by pressing - this will allow you to close the circuit again and ensure the operation of the device, but there are two points here. The first is that the thermal protection button in almost all round and flat water heaters is located inside, and in order to press it, you will need to drain the water from the tank and remove its plastic cover. The second is that it is imperative to eliminate the causes of thermal protection operation: in practice, this means that the boiler will have to be cleaned (most often it is the heating element that is descaled). After cleaning, the boiler is assembled in the reverse order, the entire chain of wires, starting with the plug and ending with the heating element, is called, after which the equipment starts up.
