Why the flow water heater stopped working

Device and circuit of an electrical flow water heater

First of all, consider the device of a flow water heater.

Everything is very simple. water passing through the heating element heats up, its temperature depends on the power of the heating element (heating water) and on the velocity of the water flow. This is the basic principle of operation of a flow water heater.

It is obvious that the greater the heater power and less the speed of the water flow, the more it will heat up.

The main minus of it is perhaps the most non.electrical device in the house. Gas water heaters are much more economical.

But, as usual, at first a little theory. As for how to install and repair the water heater. I have an article installation and repair of running water heaters. I also have articles about the accumulative heaters (boilers): repair of the accumulative heater and replacing the heater in Boyler.

The difference between flowing water heaters and accumulative

The difference is visible immediately, from the name. the water proceeds or accumulates. The pros and cons (or differences) of these two types of water heaters are listed below.

Characteristics of electric water heaters

  • The dimensions and mass of the heater. The prototing dimensions are much smaller, it can be generally hidden under the sink or for example in the cabinet nearby, its weight is about 1 kg. The accumulative is a large tank with a capacity of about 200 liters, respectively, and its weight in a “charged” state. more than 200 kg. Addting water heaters with a capacity of more than 200 liters are installed, as a rule, in the floor version.
  • Power consumption. This parameter is very important from the point of view of electricians, then in the article he will be given great attention. It is very large for the running heater, and it can be comparable to the power that the whole apartment consumes. 7 kW and above. The accumulative heater consumes electricity less. 1.5 3 kW
  • The speed of heating water. The main plus of a flow water heater is the speed of work. He opened the tap. and after a couple of seconds “Teplynaya went”. The accumulative one immediately warms the entire volume, and to heat the water to normal temperature, it may be needed to be up to an hour.
  • Price. Here the difference is noticeable, for flowing the price is 1,500-2000, the price of accumulative is 2-3 times higher. The “normal” storage water heater begins with a price of 6,000, but again, everything depends on the desired parameters.
  • I would still divide the flowing into 2 groups by design. There are those who just have a way out of a half.inch pipe (hose), and then it can be connected wherever you want. And there are those who have a crane or a hose with a shower in the design.

The boiler does not work (does not turn on). what are the causes of the malfunction and what to do

Why the flow water heater does not turn on, there can be many reasons, consider the most common malfunctions.

    Lack of feeding on the device. Firstly, the cable itself that connects the device with the shield can be damaged, call its ends by the tester or indicator screwdriver. The indicator should glow on only one wire, in the phase, neither “zero” nor “earth” in a good wire glow. If the cable is damaged, the boiler can be beaten by current.

Secondly, you should check if the fuse has knocked out. When installing for reliable operation of the water heater, it should be taken into account that for units with a capacity of more than 3 kW, a wire with a cross section of at least 4 kV is used.mm, for disconnecting from power, a double.pole switch with a fuse is used, the machine should be 30 A at a power of 5 kW and 40 A.

over, Termyx Stream is characterized by separate inclusion of each of the two heating elements, thereby you can regulate the electricity consumed and the rate of water heating. If a model without a protective flask, a scale forms on a heating element over time, which corrodes the metal and causes the failure of the heater.

You can check its serviceability using a tester by measuring the resistance at its contacts, the lack of resistance indicates its breakdown. If the heater broke, the easiest way will be to buy a new heater, since its price is not much less than the device itself. But if you decide to change the heater, you should remember that its power should be exactly the same as the original.

They burn most often due to the fact that the device is turned on with small pressure, the sensors do not have time to work, as a result, the heater burns. To reduce the effects of aggressive impurities in water, the filter should be put.

The microwter provides the supply of electric energy to the heating element. The membrane under the influence of various impurities and salts contained in water, under the influence of low temperature, if the device is used in the country, since time loses its elasticity and cannot affect the micro.transcript of.

For example, in Gorenie models, Ariston, working pressure should be 0.6 MPa. If the pressure is smaller, it is necessary to put the pump. In some cases, it is enough to install the heater below as close to the pipe as possible.

There are reverse situations when the device does not turn off. This can happen when the switch button is melted, with a temperature sensor malfunction, they can stick the relay contacts and do not turn off the heater when the water supply is stopped. When using ATN for reliable and long work, you should remember that water is turned on first, and then electricity is turned off in the reverse order.

The main malfunctions

The reasons why the Termies water heater does not work, several. The most likely are calculated thanks to these nuances of the “behavior” of the device:

It doesn’t work at all

If the water heater does not turn on, then the reason can lie not only in the device itself. It also happens that the outlet and electricity simply does not reach the water heater.

There are few buttons on modern water heater, but if the device does not turn on, this is noticeable immediately the USRAPI source.com

To check the socket for serviceability, you will need a multimeter or indicator screwdriver.

Checking the outlet is carried out in several stages:

Now the device will be able to show voltage. If it is approximately equal to 220 V, then the socket works correctly. With voltage values ​​below 200 V, you will need to carry out repair work to eliminate the deficiency.

If an indicator screwdriver is used for verification, then it must be inserted into one, and then into the other hole of the outlet. With one of the contacts, the diode should light up in it. True, the minus of the screwdriver is that if the zero wire is faulty, then this cannot be found.

If the socket is serviceable and the water heater does not turn on, then it is necessary to proceed to testing the power wire itself. To do this, you need to call the device using a multimeter. Apply one probe to one of the sides of the fork, and the other probe. to the terminal box of the boiler. If the device is silent, then you will need to replace one or both wires. In the absence of malfunctions, the multimeter will give a sound signal.

The boiler does not heat up, although the indicator is on fire

In this case, the water heater malfunction most likely lies in the heating element (Ten). That is, the nutrition is supplied, but the heater does not heat up.

To replace the heating element, it will be required:

  • Disconnect the device from the network.
  • Drain all the water from the tank. To do this, you need to put a rubber tube instead of a drain crane through which water will be merged.
  • Remove the plastic casing. The screws that need to be unscrewed are hidden behind the stickers.
  • Remove the voltage terminals with the heater. The method of their fastening will depend on the type and model of the heater.
  • Remove the heating element from the body. This will also need to unscrew the bolts.
  • Install a new heater.

Most often, new heating elements are working. But for complete confidence, you can check the detail for serviceability using a multimeter working in resistance checking mode. Correct value on working devices. 0. If the multimeter shows resistance 1, then there is a gap in the element tube.

Much less often the reason for the occurrence of such a problem is the control unit. He may begin to work incorrectly, so the only way to correct the situation is to replace the entire panel.

Slow water heating

Such a fault of the water heater for the Termy of 50 liters can have three reasons at once.

  • The heating element cannot work correctly due to the presence of a dense layer of scale.
  • The control unit is broken. In this case, he begins to incorrectly give commands to the whole device. If the block has become faulty, then the corresponding error code will be reflected on the display.
flow, water, heater, stopped

Each of the problems will use its own solution. If the thermostat breaks, then it will need to be replaced. To do this, the water heater is disconnected from the network, the protective casing is removed, the thermostat itself is removed. The device is attached to four bolts, and electricity is supplied to it using terminals that need to be removed. A new device is installed.

If the heating element is covered with a scale, then it is necessary to remove the heater according to the instructions that were given above and place the part in an alkaline solution. The aggressive environment will gradually remove the resulting scale.

But when an error appears on the control unit, it will be difficult to reanimate the technique. It is best to invite a specialist who will examine and issue his verdict. In most cases, the panel itself is simply replaced, since it is usually unprofitable to repair it.

The case is energized

This is a dangerous problem fraught with obtaining electrical studies in contact with the body. “Pierces” the case on the case usually a heating element, when defects appear in it over time. Although sometimes a power cable malfunction leads to this result. In any case, if the case begins to beat with current, then in the system it is necessary to immediately eliminate the malfunction.

The water heater began to flow

The water heater in the Termyx of the malfunction and their elimination depend on the reasons why a similar situation has formed. One of the possible problems is a leak that can occur due to improper installation of the device. within a few days, or after several years of operation.

Insufficient pressure of water

There are cases, the gas column does not warm the water due to the false works of safety sensors. When the water pressure is excessively weak, the system immediately turns off the device.

  • Will contact the utility service. Perhaps the water leak on the pipeline has formed.
  • Clean filters.
  • Remove the scale from the water heating element.
  • Check the membrane.

Sometimes with minimal water pressure, the gas column heats it too much. This applies only to old models, since they do not provide a protection system: in the absence of water, they continue to burn. For safety reasons, it is advisable to replace the outdated device with modern.

If cold water flows with the same weak pressure as the hot, the problem of the gas column lies in the malfunctions of the water supply, the source of Cosmo-Frost.ru

Failure of the burner

It happens that the water heater functions, but does not heat the water to the required temperature. Often this happens as a result of weak burning. Then the liquid simply does not have time to warm up to the necessary indicators. In such situations, the fire in the burner usually hopes, has a specific shade. The indicated signs indicate the clogging of a faint or burner of soot, soot.

Disassembling a burning device, thorough cleaning of clogged parts will help get rid of such a problem. If there is a gas filter, it must also be checked for clogging.

In the columns with a piezo-Zhizhg, the Selloil should be burned constantly, because when the hot water crane opens, it should make the main burner the source of Cosmo-Frost.ru

Sudden attenuation of the device

If the water does not heat up because the gas column rises immediately or some time after turning on, the following breakdowns are possible:

  • Magnetic valve contact with thermocouple is disturbed. This is due to short circuits that occur with damage to the insulation. As a result, the device is randomly lights up and goes out. This problem is eliminated by replacing wires.
  • Damage to a water heater auto.regulator system. You can detect such a problem after a short observation of the work of the device. If it operates normally for ten minutes, but then it goes out and lights up again, it is necessary to repair the combustion sensor.

Advice! Repair of gas equipment electronics is best entrusted to specialists.

flow, water, heater, stopped

Repair of the electronics of the gas column requires certain knowledge and skills, therefore it is better to entrust it to professionals the source of Remont57.KH.ua

Water blocking

The cause of poor water heating in the gas column may be clogging of the water supply. To eliminate it, it is required:

If the above actions did not help, you should contact employees of the communal service. You may have to change old pipes.

flow, water, heater, stopped

Flow in the column

The gas water heater also does not warm the water well when the leak is formed. Detecting it is simple: oily liquid flows through the tubes. This happens for the following reasons:

In the first case, it is necessary to replace worn elements with new (preferably silicone), in the second. to seize the hole. To do this, you will have to use the services of the master. Under any circumstances, soldering will cost much cheaper than the acquisition of a new heater.

Before starting the soldering, it is necessary to drain the water from the heat exchanger, otherwise the fluid will remove heat, and it will be impossible to warm up the damaged place to the required temperature.Industriya-Holoda.ru

There are many reasons why the gas column does not heat water. The problem can be hidden inside the unit itself or in external pipes. In order to find a malfunction and quickly eliminate it, it is recommended to familiarize yourself with the device of the water heater, the most common breakdowns. If you do not manage to repair the device yourself, you should contact a specialist. He will carry out repairs qualitatively, provide a guarantee for work performed. Any gas column will serve much longer if it is periodically conducting its maintenance, clean the pipes in time.

The main reasons for the violation of equipment launch

To determine the malfunction, it is necessary to analyze the work of the equipment. The following phenomena are considered the most common:

  • Gas pressure indicators do not meet the technical requirements.
  • The appearance of blockages.
  • Damage to electronics.
  • Lack of a spark of piezoelectric element or a damage to the litter.
  • The pressure of the water is too weak.
  • Bencing of the diaphragm.
  • Disruption of the smoke removal system.

Wabled gas speakers work without noise and should work a few seconds after the opening of the water.

Gas pressure indicators do not meet the technical requirements

Insufficient gas pressure in the pipeline is accompanied by violations of the equipment working from blue fuel. You can check this by turning on the stove. If the pressure of the gas is low, it is necessary to contact specialists and report the problem, since independent repair can lead to tragedy.

With complex breakdowns and non.compliance of the characteristics, it is necessary to call professional repairmen source of Dnevnik.HR


It is advisable to equip the entrance to the column with filters, since there are mechanical impurities that can damage the equipment in the water. Gradually on filters, salts that prevent fluid passing. This leads to the fact that the gas column does not light up.

To correct the situation, it is necessary to eliminate the contaminants accumulated on the filter, or put a new.

If the column has been for many years, then blocks arise in a heat exchanger or tubes. You need to check the water node and find out the level of patency of the elements. Special reagents help to remove blockages, after washing which, the performance of the device will be restored.

If the pollution has accumulated in the burner, it is necessary to disassemble the column and extract the part. After cleaning it, you need to put it in place and check.

Electronics failed

Successful operation of modern devices depends on electronic blocks and sensors that regulate various processes inside the units. If one of these elements fails, then the device will fail. Because of this, electronics will not allow you to perform ignition. Repair in this situation is difficult to carry out independently for those who do not understand electronics.

The electronic fee of the gas column is also responsible for protection. even attempts to independently repair this unit is better not to carry out the source of Prom.ST

Problems with piezoelectric element

The column does not ignite when the water is opened in such cases:

  • Piezoelent and electrode failed or shifted. At the same time, the piezoelectric element remains on for 30 seconds, and after that the wick turns off. To restore performance will help replace the assembly.
  • It is not possible to light the device if the user does not adhere to the manufacturer’s recommendations on the operation of the equipment. Before clicking on the power button, you need to press the gas supply handle for 10 seconds. A security system has been installed inside the water heaters, which prevents gas supply until the smellor is warmed up by enough. If the device does not turn on, although there is a spark, you must familiarize yourself with the recommendations of the manufacturer.

To replace or resolve the piezoelectric element, you need to have special tools and skills. Therefore, it is better to apply for the services of the master.

Damage to the carrier

Violation of the functions of equipment may be associated with the following problems:

  • Discharged batteries. Then the spark is triggered, but due to insufficient power, the burner cannot warm up. This is the main reason why the gas column does not turn on the batteries. The first thing to do is replace the nutritional element.
  • Damage to the hydrogenerator. The hydrogenerator is called the turbine that produces electricity while driving. This element shows high sensitivity to the state and pressure. If it does not work, you need to inspect the presence of deposits. To stabilize pressure, use special pumps.
  • Failure of the power supply unit. There is no sparks if the power is fishewent. This is possible when oxidizing contacts, bloating resistors. If you have skills in working with a soldering iron, you can handle the grinding yourself. Usually, they prefer to install a new power supply, because its breakdown is the main reason why the gas column does not light up with automatic ignition.

Good batteries for the column will be enough for 6-8 months. After this period, in the operation of the device there will be malfunctions.

Too weak pressure of water

The requirements for the operation of gas equipment indicate under what conditions you can operate the device and what is needed for its normal operation. If the pressure is weak, then the water heater does not turn on and this does not mean that it has failed. The problem is related to non.compliance with technical conditions. To normalize the work, you can use the storage tank and a raising pump.

In automatic heat generators at low pressure, a water unit does not work. This is due to the structure of the structure and operation of the element. In the inside there is a membrane. It divides into two cavities, inside one of them there is a rod that is responsible for adjusting gas supply. So that the rod begins to move, it must press the membrane on it. If the pressure of water in the pipes is low, the rod remains motionless and there is no spark, so the gas is not supplied to the burner.

Ariston water heater does not work. the reasons for the breakdown and their elimination

One of the reasons why the water heater does not turn on is the lack of power supply to the unit. With the help of a tester or indicator screwdriver, the presence of a signal in the cable should be checked, the indicator lights up on the “phase”, on the “zero” and “land” in working condition there is no signal.

When replacing, choose a cable with the same parameters as on the original. For installation, take the cable into the corresponding hole in the rear panel of the device and connect to the terminal block. Fix each of the wires with appropriate bolts. If the wire is working, make sure the wires with the terminals on the boiler is reliable.

The cause may be a faulty outlet, this can be checked by connecting a working electrical appliance to the outlet. The outlet must be selected with the corresponding power of the unit with parameters. It will be useful to verify the correct connection of grounding on a network outlet.

If the ground is incorrectly connected, in case of short circuit, a protective shutdown device may not work and your unit will fail. With increasing voltage on the network and when the heating site is burned, the RCD turns off the device from power supply and this may also cause why your Ariston water heater does not work.

The breakdown of the RCD itself can also cause a water heater malfunction. To check, press the RESET button on the RCD, if the indicator caught fire, then there is a power, then press the Test button, the indicator will go out, the feed will stop, then the reset is again, if the indicator has caught fire, the RCD regularly.


The voltage to the water heater is supplied, but the boiler does not turn on and due to the fault failure. To check the serviceability of the heating element, disconnect the boiler from the network and the Slaces of it. Remove the heater body for 80 liters with an autoclave flange for Ariston models, unscrew the nut, free the flange holder and open the flange, squeezing it inside.

Remove the flange by turning it around the axis. For other models, to extract it, you just need to unscrew five nuts. The heating element and the anode are attached to the flange.To check the performance of the heating element using a tester, set it on the resistance scale and connecting the ends to the contacts of the element.

Ten does not have a certain resistance value, even a slight deviation of the arrow speaks of the serviceability of the element. If the signal is absent during the check, then the heating element is faulty, its replacement is required. When replacing, change the flange seal. Ten breakdown is a consequence of the formation of a large layer of scale due to untimely replacement of the anode.

The anode should be changed at least once every two years. Before installing a new heater, you should clean the tank from scale. When installing a new heating element, follow the manufacturer’s recommendations prescribed in the instructions, the tightening of the bolts is made evenly, without stretching and jerks so as not to damage the element.

Ten with an anode

If the boiler does not warm the water, a linear thermostat can be a culprit. To check this, you need to restart the thermostat with a platoon button. If the restart does not occur, this indicates a breakdown of the thermostat. In addition, performance can also be checked using the tester by checking the resistance.

In this case, the regulator needs to be set to the “maximum” position, connect the ends of the tester to the terminal terminals, even a slight deviation of the arrow will talk about the performance of the device. Then install the regulator to the “minimum” position, heat the thermostat flask by any source of fire, you can make matches, in the working device the tester arrow shines in the opposite position from zero.

It is impossible to eliminate the malfunction of the thermostat, the installation of a new. To extract and replace the thermostat on Ariston, you need to disconnect the supply cable and wires of the electronic board. Then, observing caution, pull the thermostat out of the hole, without bending the long bar, on which the sensors are located.

You should install a new one exactly in the same position in which there was a full.time. The failure of this device occurs most often either when the boiler turns on without water, or when its resource is worked out.

We bring to your attention two parts of the video about the repair of Ariston water heater with your own hands:

Why does the boiler does not warm and the light does not burn?

If your water heater has stopped heating water, the very first thing to do, if the power is supplied to the unit. Check if there is a contact in the cable connecting the boiler with a socket or an electrical panel, depending on how you have a connection.

You can test the cable using an indicator screwdriver or tester, calling its ends. The indicator must light up on the “phase”, on the “zero” and “earth” in the good wire there is no signal. The reason for the lack of nutrition can lie in the outlet itself, this can be checked by connecting any other working device to it.

If it is faulty, most likely, the parameters of the outlet do not correspond to the power of the device. Check if the fuse has knocked out, this can happen while connecting several large power devices. Then check the contact of the cable with the terminals on the water heater, it can weaken over time or burn out the connection. In the absence of power supply to the unit, the indicator will not burn.

Everything is in order with the power supply, and the accumulative boiler does not warm and the indicator light does not burn? The reason lies in the breakdown of the internal elements of the boiler. To identify and eliminate the breakdown, the heater should be de.energized and water is drained from it. Then the casing of the case is removed from the water heater, parts are extracted for verification.

When the boiler has stopped warming the water, you should check the serviceability of the thermostat. To check its performance, the tester is used, its contacts are connected to the contacts of the thermostat. If the device shows the voltage, for the restart, click on the thermostat launch button.

Testing of the operability of the thermostat

The inclusion happened, which means that the unit was disconnected due to the trigger of thermal protection. Why in the unit thermal protection is triggered. after heating the water above ninety degrees, the protection disconnects the device. It can also happen due to the presence of a thick layer of scale on the heating element, to eliminate the problem, you need to clean the plaque on the heater.

In the case when, after pressing the thermal protection button, the inclusion did not occur, most likely, the thermostat is faulty and it should be replaced with a new.

In the absence of heating of the water heater, a frequent of the heating element becomes a common cause. The average service life of Ten is about four years. If you do not change the anode in a timely manner, this period can be significantly reduced.

The serviceability of the heater is checked by the tester, the resistance on the contacts is measured, if the resistance is absent, the heater is faulty. When the water heater seems to be working, the indicator light is burning, but slowly and poorly heats the water, it is necessary to clean the heating element and the tank from the scale.

Ten check

In addition, a breakdown on the case occurs, which can also be detected with a tester. When the protective shutdown device is broken. In both cases, it is impossible to repair the heater, it is required to replace it. When buying, an element is selected with similar parameters.

Why does a flowing heater not work

If a flowing water heater does not work, first of all, you should also check the power cable. The prototypees, as a rule, have great power than the drive apparatus.

For stable operation, the connection should be made by a cable with a cross section of at least 4 kV. mm. With a power of 5 kW, a separate machine is connected to 30 A, from 7 kW. by 40 A. Otherwise, your EVN will not work long. You should check the serviceability of the RCD by pressing the “Test” buttons on it, the working RCD should be disconnected. It will be useful to check the reliability of the connection of the wires on the shield.

The heating breakdown in the prototype most often occurs due to the low supplying water pressure, when the pressure sensor does not have time to work, the heating element burns out. In addition, if the design of the EVN is arranged in such a way that the heater is in direct contact with water, and not in a protective flask, it is possible to corrode with salts of the surface of the heating element.

Ten is a flow water heater

Incorrect installation of the device also causes burning out, it should be carried out strictly with the recommendations of the manufacturer, since changing the installation angle leads to the fact that the thermostat probe does not contact the spiral, it is combined. In any case, the heater itself most often changes, since the cost of Ten is slightly less than the cost of the EVN.

The malfunction of the water heater pressure sensor is often the reason that your device does not turn on. The main element of this sensor is the rubber membrane, which, under pressure from passing water, turns on the microswell. During operation, it can stretch, break due to the negative effect of salts in the composition of the water. In this case, it needs to be replaced, it is better to purchase silicone, it will last longer.

The temperature sensor can also be the cause of the malfunction. To determine its performance, call its contacts, if the signal is absent, the sensor is faulty, it cannot be repaired.

Water temperature sensor

EVN may not work either because the contacts often burn out contacts in the places of wire connections with terminals. From time to time, it is necessary to check the strength of the compounds and tighten the weakened contacts.

How to connect a flowing water heater

What should first of all pay attention to the electrician when installing a water heater, and any electrical appliance? Correctly, on the power consumed. It is usually indicated on the back wall of any device:

TermEx_ Vyda flower in the back

Larger, so that everyone can see the characteristics:

The idle water heater Thermach. characteristics

6 kilowatts of power consumed! This is a current 6000 W / 220 c = 27 amperes! What does this mean? It will not work to insert this device into the outlet, here without options.

As you know, a standard outlet withstands current up to 16a, and then this is a short-term and theoretical. This is a power 16220 = 3.5 kW. And here. 2 times more.

For such an electric heating device, it is necessary to conduct a separate fishing line for a trimmer, capable of providing a power of at least 6 kW, this is comparable with the consumption of the whole house. Therefore, to connect a flow water heater, you need a separate cable, and a separate machine, this is necessarily. We need a cable with a section of 4 squares, more about the choice of section. in my article. The wire area of ​​the section 2.5 squares will be very hot.

The accumulative heaters, as a rule, are connected through a conventional outlet. After all, the power they consume is rarely more than 3 kW.

At the choice of a protective machine, there is also an article, its face value is selected between the current current and the current of the wire. Optimally in this case. 32 amperes.

It is very important to make reliable grounding. According to the rules, it is necessarily done for all devices having any metal parts and/or contact with water. The cross.sectional area of ​​the grounding wire should be equal or one step more than the phase supply wire.

In general, it is wonderful if the water heater is connected through the RCD (differential machine). Then, with any problems with isolation or in case of accidental touch to the current.carrying parts of the RCD, the power will turn off, and the tragedy will not happen.

Water connection

Here you have to work a little plumber, since there is no special wisdom in this matter.

Make a discharge from cold water, apply it to the heater input. The heater is released to the hot water crane. This is how it is drawn in the instructions:

Connection of the water heater to the water supply

At the place of removal of cold water, you will have to put a tee, two more flexible hoses, a fum-tape, so that nothing is dripping anywhere.

The installation option of a flow water heater Termyx

Here is another option for installing a flow heater:

Installation of a running water heater in the shower

Connection of water, hot and cold. red and blue, output and entrance

Power supply via a socket on the wall in the shower

For security reasons, electrical connection should be made according to the instructions, using RCDs and grounding.

On this with the installation we finish, go to repair.

Ways to eliminate a malfunction

Replacing the heater

Despite the differences in appearance and design, the process of replacing the heater in the Ariston, Electrolux and other popular brands are the same.

For work, you will need the following set of tools:

Regardless of which of the reasons the water heater is not able to heat the water to the required temperature, the following actions must be performed to change the heater:

  • Block the flow of water into the boiler on the riser. Hot water tap also needs to be installed in a closed position.
  • Remove all water.
  • Disconnect power from the network.
  • Remove the lid and make sure of the indicator screwdriver in the absence of voltage on the terminals. Remove and install wall models on the floor.
  • Unscrew the nuts and disconnect the wires, fixing the connection procedure in order to install them in place when assembling without problems. It is desirable to photograph the process.

In the process of replacement, it is necessary to ensure that moisture does not get on the contacts.

Often, together with the heating element, it is necessary to replace and protects it from the deposits of the anode. You should also inspect the gaskets placed between the heater and the tank. If there are dents or gaps for insulation, then it is necessary to change it.

Roxas, Isabela. How Flow sensor works in Water heaters

The installation of a new heating element is performed in the reverse order. Before turning on, the device is checked for the lack of leak.

Ten cleaning

A solution of citric acid is used to clean the heater coated, prepared at the rate of 50 g of “lemon” per 1 liter of water. The solution must be prepared in such a volume that a heating element can be completely placed in it.

Having held the heater in the solution for a couple of days, the remaining scale and dirt are neatly removed by a hard brush.

Replacement of the thermostat

The work is performed in the following sequence:

  • The clamping ring located near the heater is removed;
  • The thermostat sensors and the adjustment unit are extracted;
  • a new device and a clamping ring are installed;
  • The water heater is assembled.

Immediately after replacing the thermostat, you cannot use the device. First you need to make sure of the flow of cold water, inspect the compounds for leaks and, opening a hot valve, lower the accumulated air. Then the device is connected to the electrical network, a trial launch with a gradual increase in heating temperature is performed.

During the operation of the water heater, the fork is heated

During operation of the boiler, a slight heating of the fork is allowed, since the device is quite powerful and consumes 1.2-2.6 kW.

But what to do when the wire and fork are too strong?

  • Inspect extension cords and tees through which the device is connected. If there are doubts in quality, it is better to refrain from their operation. From the point of view of fire safety, it is necessary to use an extension cord with a large section of wires.
  • Check the outlet from which the boiler eats. With prolonged use, the socket is loosened and the plug does not fit to the contacts, which leads to an increase in the temperature of the fork. It is recommended to constantly check the density of planting the outlet in the nest, and if the fork is easily removed or dumped, the device should be replaced.

If only a plug and a slight length of the co.adjacent cable are heated, then the problem is most likely in poor contact of the internal wires. In a collapsible design fork, the malfunction is eliminated quickly. just squeeze the terminals. The indispensable fork will have to be replaced.

Cording can be explained as follows:

  • Extension extension cord. It is necessary to replace the device with a more powerful.
  • There is a breakdown of the heating element on the body of the boiler or the connection sites in the heater burned out.

These malfunctions lead to the fact that the wire may light up. Therefore, for security reasons, the heating element should be replaced or reliably insinterate the connection points of the wiring.

Why a flowing type water heater may not warm water

The volume of running water heaters is much less accumulative, therefore, for heating the same amount of water, they consume more electricity.

There are several reasons why the flow device does not heat the water:

The best solution is to replace the element, and not eliminate the malfunction by winding of the nichrome wire. It is necessary to take into account the specifics of running instruments: in the manufacture of spirals in the factory, they are covered with ceramics to prevent the sedimentation of scale.

Some models of devices are equipped with a fixed heater, for the dismantling of which you will need to hack the copper membrane, followed by its sealing or brewing.

The water flow sensor does not give a heating spiral signal. This feature is often found in running water heaters of various brands and models, including Atmor.

To check the condition of the radiator, it is necessary to de.energize the water heater and disassemble it. It is recommended to flush the element with any available tool for cleaning from scale. With strong clogging, the radiator should be soaked in water for several hours.

If the device is not used for a long time, it is necessary to completely remove the water from all hoses and sleeves. To prevent scale deposits, it is recommended to filter water before entering the heater. You can purchase filters at the most profitable in Tyumen from Kwanta. Our experts will answer all questions of interest, help with the choice of the most suitable model for specific operating conditions.
