Repair of electric water heaters Ariston. Do-it-yourself Ariston water heater repair - typical breakdowns

Ariston water heater models are popular among consumers, as they not only have a beautiful appearance, good technical characteristics, but they also have an average cost. When connecting Ariston, you can make mistakes that will entail some inconvenience. Among them: replacing the check valve of the company with a conventional safety valve or removing it from the system.

In order not to have to constantly repair Ariston water heaters, or each time it breaks down, do not replace the entire boiler, then remember some rules and understand its features.

Possible problems

If, after installing the water heater, they notice that the tank is leaking, and when cleaning the tena, the enamel peels off, which means that a number of inaccuracies were made during installation. Let's consider some of them:

if the connection was made directly to the water supply network, that is, one pipe enters and the second exits, and there are no adapters, then the pressure is constantly changing, and with it the boiler tank either fills up or not, and therefore, fatigue stress of steel occurs, enamel cracked and the seams come apart. This will become noticeable after a certain time, but then it will be too late to do something, because if the tank is leaking, then it must be replaced with a new one. And even at high temperatures, a polymer heat insulator can get into the water, which is extremely dangerous for human health;
a branded check valve cannot be replaced with a conventional one, since the factory one is combined with a bypass valve. When heated, water expands faster than steel. If the situation is normal, then the excess pressure will collide with the bypass valve, otherwise the tank will stretch like a heating pad. At first, it will increase by several liters, and after the container bursts, water will seep through the cracks;
if, during installation, a shut-off valve was mounted between the bypass valve and the tank, then this is also wrong. In the case when, with the tap closed, the water is either cooled or heated, then deformation of the water heater occurs.

Consider how to properly drain the water from the Ariston water heater. For this:

open the hot water valve, which will allow air to enter the tank;
a hose is connected to the cold pipe and lowered into the sewer;
open the drain valve and empty the boiler.

The plant does not produce flow models electric water heaters ariston, so the device has a magnesium anode and a steel tank.

During cleaning from scale and pollution, it is necessary to remove the ten. The Ariston storage water heater has a vertical type design, which has a removable panel at the bottom. Ten is fastened with bolts or nuts, but after it is taken out, the thermostat with a probe is removed, which is located inside the heating element. A relay is also located here, which is triggered at the moment when the water reaches the desired temperature.

When descaling, citric acid is used, its concentration should be 4.5%, and the temperature of the liquid should be up to 45 ° C. For the whole night, a ten is put into the solution, which is poured into a 2 liter container, and in the morning the remaining pieces are easily cleaned from it. It is taken into account that the heating element of the Ariston boiler is longer than in devices equipped with a blade contact.

If you need to move the boiler to another place, then for this choose metal-plastic or polypropylene pipes which provide a high quality connection. The joints are covered with sealant or sealed with Fum tape or linen.

The advantage of this brand of water heater is that an autoclave flange is used here, it does not allow leaks to form. That is, water cannot seep through the gasket. This element is pressed under pressure, and the higher it is, the stronger it is pressed.

How to carry out repairs

All actions are divided into the following stages:

make diagnostics;
determine the fault;
replace or repair the damaged part.

In order to repair the Ariston water heater with your own hands, a malfunction is first detected. More often it can be a burnt ten, so it has to be replaced. For this:

disconnect the boiler from the flow of water and current;
remove the protective box (unscrew 2 screws);
unscrew the cover of the water heater;
remove the check valve;
water is drained from the device;
unscrew the nut that holds the plank with the flange;
carefully move the ten inside and pull it out, and for this they unfold it;
clean the unit, and the magnesium electrode from scale, dirt.
insert a heating element;
all parts are installed in the reverse order;
check the tank for leaks.

Conclusion

Despite the fact that an Ariston water heater of 80 liters or another volume is being repaired, it is necessary to strictly follow the instructions and, if necessary, replace all damaged elements with new ones. At the same time, they take into account that they must be released only by Ariston, otherwise they will quickly fail. And this will entail unnecessary financial costs, since you will have to re-purchase the same parts.

If they don’t know how to repair Ariston on their own, then they call in specialists who will do everything that is necessary not only qualitatively, but also in a short period of time. If necessary, they will help you choose and purchase the necessary parts and elements.

Do-it-yourself repair of an Ariston 80 liter water heater is possible if you know how the device is folded and what problems it may have.

Features of the water heater device Ariston 80 liters

This water heater is considered the best in its range for use in a family apartment. It is medium in size and easy to install. Horizontal device. Therefore, it can be installed directly under the ceiling.

The main disadvantage of the boiler is the frequent malfunction of the display. However, his work does not affect the functioning of the water heater itself.

Such a boiler can break down when the water remaining in it freezes. It is necessary to drain the water all the way to the end, although the manufacturer claims that the device is resistant to freezing.

The maximum water heating temperature is 80 degrees. But if you use such heating constantly, then the boiler will quickly fail. The optimum heating temperature is 60 degrees.

Features of replacing a faulty heating element

If the boiler has stopped heating water to the desired temperatures, then the heating element should be replaced. To do this, follow the following procedure:

Switch off the device from the electrical network.
Stop supplying water to the tank.
Connect a hose to the drain tap and drain all the water into the sewer.
Remove the protective box by unscrewing 2 screws.
Remove the return valve from the pipe.
Drain the remaining water from the tank.
Unscrew the nut that secures the flange with a wrench.
Carefully remove the old heating element without damaging the flange.
Clean the walls of the container from accumulated dirt. If the walls have a special protective enamel inside, then it is not necessary to remove the scale. You can simply damage the protective film. This layer of scale will protect the walls of the vessel from rust formation.
The magnesium anode is removed and repaired, if required.
A new heating element is being installed. You need to do exactly the opposite.
Verification of work after the final assembly of all parts. The tank must not leak. Otherwise, you need to put new gaskets.

Weaknesses of the water heater

The Ariston brand is considered one of the most reliable. But, despite this, these boilers have their drawbacks. Very quickly after the purchase of the device and the start of its operation, the scoreboard reflecting the main parameters of the boiler operation fails. However, it is intended for the convenience of the user. A broken panel does not affect the operation of the boiler itself.

Although the manufacturer indicates the frost resistance of the device, the water from it must be completely drained during downtime. Frozen residues may damage the device.

The temperature maximum of the Ariston boiler is 80 degrees. But it is not recommended to use it. The boiler will fail very quickly in this case. It is best to produce heating up to 60 degrees.

If all these shortcomings are taken into account during the operation of the device, then it will last for many years.

According to user reviews in the network, Ariston water heaters have firmly established their positions in the TOP 10 manufacturers of heating devices. However, even the "golden" technology is not eternal: there comes a time when a radical fix is required. Of course, it is better to contact a qualified specialist. But an elementary repair of Ariston water heaters with your own hands is also quite possible.

The most vulnerable points of Ariston gas, electric and instantaneous boilers are thermostats, sensors, switches and heating elements. Branded valves that insulate gaskets often break. Violation of the integrity of the tank occurs much less frequently, this is due to corrosion or careless handling, but even service centers rarely agree to eliminate such a malfunction.

Self cleaning water heater

Any Ariston boiler needs periodic descaling. Experts recommend doing this regularly (once or a half a year). The final verdict on cleaning the heating element from scale depends on the frequency of use of the device, as well as the quality of the liquid. Determining that the moment has come is easy. It is enough to pay attention to the obvious changes:

an uncharacteristic hiss appeared when heated;
heating time increased;
The boiler started turning on and off more often.

Despite the high quality of parts for Ariston boilers, standard maintenance of any model will not cause difficulty even for beginners. If you have free time, obedient hands and enough patience, then it is not necessary to spend your personal budget on specialists, you can repair the water heater yourself. Review the following simple maintenance procedure:

1. De-energize the room and turn off the water heater by disconnecting the wires from the thermostat.

2. Start draining: select a hose whose diameter is a few millimeters smaller than the water discharge outlet (where the safety valve is). Disconnect the hot water pipe from the boiler without closing the tap - this action opens the valve.

3. Lower the free end of the hose into a sink, tub or toilet.

Attention! If there is no safety valve on the drain channel, we recommend installing one in the future. And for such a case, before draining the liquid, perform the following simple algorithm.

close the feed channel cold water;
disconnect the hose from it;
then connect to the ball valve;
go back to point 3.

4. Continuing to repair the Ariston boiler and clean it on your own, remove the heating element (it is usually fastened with a nut on a metal plate). After removing the water heater from the mounts, carefully pull out the thermostat. To make it easier to get the heating element, push the flange inside the heater, then try to pull it out.

5. In the hole you will see the scale that has formed, which will need to be removed, which can be done simply with your hands or with a technical rag with a tool that neutralizes limestone deposits. But in no case do not use abrasive materials, this adversely affects the surface of the device. If there is no special remedy in the house, use the proven folk method: dilute citric acid in water, pour Ariston into the tank of the water heater and let it stand for a day.

After the procedure, rinse the water heater tank with a jet of clean water to remove scale residues. The heating element is cleaned in the same way: dip it for 1 day in a solution of citric acid. In case of critical contamination, it is better to purchase a new one, similar to the standard one. You should pay attention to the magnesium anode, which is located next to the heating element. Replacement is usually carried out once or twice a year. Use native anodes from the manufacturer for each individual Ariston water heater model.

7. It is better to connect the Ariston boiler to the supply system using plastic connecting pipes - they are more reliable and durable than conventional flexible or metal-plastic hoses.

8. Do not confuse the phase and zero! Use an indicator screwdriver to locate these pins. If you forgot how the boiler was connected initially, be guided by the diagram that is shown on the thermostat.

9. To protect yourself from electric shock during repairs, install an RCD (residual current device). It is designed to instantly turn off the water heater at the first sign of a short circuit.

10. Before the final start of the Ariston boiler, carefully check it for leaks by filling it with water. Let it stand for a couple of hours after the repair without work, and if the liquid does not leak out of the tank, the boiler can be turned on.

If you do not have enough free time or simply do not want to understand the algorithm for regular maintenance of your water heater, do not hesitate to contact specialized service centers for help. However, we warn you: the cost of an urgent repair of an Ariston brand water heater (depending on the volume: 30-150 liters) is in the range from 1,500 to 3,000 rubles.

When should you contact the service center?

If the failure of the Ariston water heater occurred during the unexpired warranty period, then a number of conditions must be met in order to repair it at the expense of the manufacturer in the service center. Namely:

the operation and installation of the water heater took place in accordance with the rules specified in the passport. Large companies offer to use their own service center in the future if the installation is carried out by their masters. The cost of repairing Ariston in the future is still included in the price of the boiler, but this will save you from unnecessary attempts to prove that the installation was carried out according to the regulated rules. Do not save, agree;
if the procedures for cleaning the tank and other preventive work were carried out by specialists in the service center;
if, when a capacity failure was detected, no attempts were made to fix something on their own. Do not touch anything, it is better to call right away, repairmen should come to your house;
there is no external mechanical damage on the Ariston boiler. Carefully inspect the water heater when buying it;
read the warranty card thoroughly. Sometimes not the entire water heater is subject to free replacement, but only its individual parts (for example, only a heating element or a thermostat).

If you plan to contact the service center, then remember that the initiative is punishable: do not interfere with the device during the warranty period. But in case of refusal of free service for a good reason, do not be discouraged, according to reviews, repair of the Ariston water heater is possible on your own.

Boiler Repair Expert Tips

In order to avoid scale formation, it is recommended to set the maximum heating level to 60 °C.
Repair of Ariston electric water heaters may not need to be carried out if the device is completely turned off every time the central heating is started so that water does not pass through it.
Do not be afraid to communicate with specialists from service centers in your city: before buying a new Ariston boiler, call and clarify which model breaks down more often and which one less often and for what reason.
Leaving water in the tank or not is a moot point. If the water stagnates, unpleasant odors will increase in the future. However, when the liquid is drained, oxygen gets inside, which provokes the rapid appearance of rust. The best option is to run water through the entire system more often.
Try not to touch the tank during operation, so as not to break the tightness of the connections. Accordingly, a leaking container cannot be used.
Before installing the Ariston water heater, carefully study its technical data sheet. Pay special attention to which elements of the device are strictly prohibited from moisture.
During installation, it is useful to make sure in advance that the pressure is no more than 6-8 atmospheres.

Please note that if you do not have basic knowledge in the field of electrical engineering, then it is better to entrust the repair of Ariston storage boilers, as well as models of other types of water heaters, to professionals.

Do-it-yourself Ariston water heater repair

To provide hot water to your apartment all year round, installing a water heater is considered the best option. If the Ariston boiler is chosen correctly in compliance with the basic conditions and operating requirements, then such a device will serve you for a relatively long time. What to do if there is a malfunction of the device and there is no hot water in the apartment? In this case, of course, you can resort to the services of service centers that repair water heaters, or you can fix the problem yourself.

The design and main elements of the Ariston water heater.

Consider the second repair option - do-it-yourself troubleshooting.

Before proceeding with the repair of the Ariston water heater, it is necessary to find out the malfunction and the cause of the failure of the device.

Malfunctions of Ariston water heaters

Scheme of connecting the storage water heater to communication systems.

Since the boilers are connected to two communication systems, the water supply and the power supply system, all problems can be divided into 2 groups. The first group includes malfunctions associated with water leakage, failure of the tank, non-return valve and elements of connection to the plumbing system. The second group includes malfunctions of electrical equipment included in the package of Ariston boiler systems.

Preparatory work

Before repairing water heaters, it is necessary to prepare tools and accessories. To eliminate mechanical disturbances associated with water leakage, you will need:

wrench;
a set of adapters;
a known good non-return valve;
welding machine in case of failure of the water heater tank.

In case of electrical malfunctions, in addition to tools, you will need a measuring device, tester or ohmmeter. The preparatory work also includes work during which water is drained from the water heater tank, and the electrical part is disconnected from the apartment power supply network.

Repair and troubleshooting for Ariston water heaters

The reason for poor heating may be a poor electrical connection between the heating element and the thermostat.

We will analyze several of the most likely malfunctions that are detected by repairing and adjusting Ariston water heaters associated with a malfunction in the water supply system and heating water to the required temperature.

One of the main malfunctions is water leakage from the boiler tank. First of all, it is necessary to visually inspect the water inlet and outlet hoses. If they are in good condition, they begin to inspect the lower part of the storage tank. To do this, after de-energizing the Ariston boiler, remove the bottom cover, which closes the electric heater, thermostat. If necessary, you can remove the thermal insulation from the bottom of the tank. If a leak is detected at the connection points, additional seals and sealant can be installed. Upon failure storage capacity more complex work is required - this is welding. Of course, you can use the so-called cold welding, but this will not give the desired result for a sufficiently long period of time.

If the tank is leaking in the water heater, additional seals and sealant are installed at the connection points.

The second most common malfunction of Ariston water heaters is the lack of water heating in the storage tank. With such a malfunction, the repair of water heaters is referred to as the repair of the electrical part of the heating device. First of all, when repairing water heaters, the presence of a mains voltage of 220 V in the apartment power supply network is checked. In the absence of voltage, the introductory circuit breakers for the apartment or house as a whole are checked. If voltage is present, they gradually approach the main element - a thermal electric heater (heater). Using an ohmmeter or tester, check the health of the cable with which the boiler is connected. If the cable is in good condition, the direct current resistance of the heating element is measured, which for a serviceable element should be several ohms and tend to zero.

In the absence of instrument readings, they are convinced of the failure of the heating element and proceed to disassemble the water heater. Before disassembling the boiler, make sure that the cold water supply system is shut off and use a hose to drain the water from the storage tank.

If a malfunction of the heating element of the Ariston water heater is detected, a mistake can be made, since there may be no water heating if the thermostat is faulty. If the measuring device shows a resistance value corresponding to the operating state of the heating element, the serviceability of the thermostat and sensors for controlling the water temperature in the tank should be checked. When repairing water heaters, you may encounter a lack of water heating with a working heater. In this case, the thermostat is considered a faulty element, which must be replaced.

Post-repair work

Regardless of what kind of malfunction was eliminated during the repair of the water heater, it is recommended to clean it from scale and debris. Before connecting to the power supply network, it is necessary to make sure that the individual elements are completely dry so as not to cause a short circuit. When connecting the Ariston boiler, also do not forget to ground the storage tank. Before filling the tank with water, make sure that the mechanical connections and fastenings of the brackets for hanging the boiler on the wall are strong.

Repairing an Ariston water heater is not very difficult, and even a non-professional in the field of plumbing and electricity can handle it.

Ariston water heater for 80 liters - do-it-yourself repair

During the operation of the Ariston storage water heater, the following problems may occur:

The unit does not turn on.
Cold water flows from the faucet.
Slightly warm or too hot water flows from the faucet
Water is dripping from the safety valve.
Tank leak.

Each of these situations requires diagnostics and repair, most of the repairs can be done by hand, with some skills. First make sure that the apartment or house has a supply of water and electricity.

Boiler does not turn on

First of all, check the power supply to your storage water heater. Pay attention to the condition of the outlet, whether it is burnt or melted, this may happen due to inappropriate parameters of the outlet and the power of the device.

Ring the wire with a tester or indicator screwdriver, the wire may be interrupted. In a working wire, the indicator lights up only on the “phase”, there is no signal on “zero” and “ground”. Check the contacts connecting the wire and the water heater, over time, the contacts oxidize and “boil”.

If this happens, unscrew the wire, strip the contacts, then reconnect the power cable. Check the health of the RCD by pressing the "Test" button, if the device turns off, this indicates the health of the RCD. Check if the wires on the electrical panel are securely connected if the wire is loose or loose. screw it on.

The reason may also be the disconnection of the fuse during power surges or in the case when the wire does not meet the parameters declared by the manufacturer. For Ariston 80 l, the cable must be marked H05VV-F 3 * 1.5 sq. mm, with a diameter of 8.5 mm, this should be taken into account in case of replacing a faulty cable.

Cold or insufficiently hot water flows from the boiler

The cause of a malfunction of this nature can be a breakdown of the heater, thermostat and a large layer of scale on these devices. Before determining the cause of the malfunction of the 80-liter Ariston water heater and doing your own repairs, you should turn off the power supply and drain the water.

Then, using a 13 wrench, a Phillips screwdriver, remove the protective box and unscrew the bolts on the mounting plate. Carefully remove the flange on which the heating element and thermostat are attached. Now you need to descale these 2 devices.

Boiler protective cover

The thermostat should be unscrewed by cleaning the attachment points to the flange from sediment, then carefully, using a screwdriver, release the thermostat from scale. You can check the performance by using a tester, the absence of a signal on its contacts indicates a malfunction and the need for replacement, since the thermostat cannot be repaired.

You can also check the heating element for operability using a tester by connecting the ends of the tester to the contacts of the heating element. If there is voltage, the heating element is working, but it needs to be cleaned. The heating element can be cleaned with a screwdriver, carefully removing pieces of deposits.

Then you need to prepare a solution of citric acid - 100 g per 1 liter of water and immerse the heating element in the solution. The effect of the solution on the device will be indicated by air bubbles that appear as a result of the reaction. If such an action is not enough for complete purification, you can put a vessel with a solution and a heating element on a slow fire.

After cleaning the heating element, it is necessary to descale the tank. Be careful not to damage the inner surface of the tank. If it is possible to remove the heater from the wall, cleaning can be done with a solution of citric acid, pouring it into the tank.

There may be a lot of debris in the tank

After the manipulations, assemble all the parts in the order in which they were disassembled and carefully insert and secure the flange. Make sure that during assembly there are no distortions of parts, do not overtighten the bolts, change the gasket between the body of your storage boiler and the flange, since the flange gasket was also exposed to salts.

dripping water

If water drips from the water heater, the cause may be the absence of a safety valve, installation of a valve with inappropriate parameters, clogging of its deposits. In this case, the excess pressure, which appears as a result of the increase in temperature and the lack of bleed, acts on the walls of the tank.

Over time, this situation leads to a violation of the integrity of the welds and the leakage of the tank. Do-it-yourself repair of the tank is impractical, if the tank is made of stainless steel, argon welding is required, carried out only by specialists, if the tank is covered with glass enamel, welding is not possible.

Replacing the tank will result in a breach of the hull. In the event of a tank leak, you will have to change the water heater. In order not to bring to this, monitor the health of the safety valve and clean it in a timely manner.

Hull corrodes from water leaks

In working condition, when heated, water should drip from it, but if water drips even when the unit is turned off, it should be calibrated or replaced with a new one. When buying a new one, be sure to choose a valve with the same parameters as on the regular one. Calibration can only be performed by service center specialists.

To determine the nature of the malfunction and eliminate it, it is desirable to have an idea about the design of the boiler. Below is a diagram of a device with a horizontal and vertical installation type.

How to repair an Ariston water heater yourself

Today, various types of heaters have become very firmly established in our modern everyday life. In specialized stores, they offer products from world-famous brand companies with very wide popularity, for example, such as Ariston. Despite the high reliability, any household appliances can fail over time for any reason. In this case, it would be useful to know how to carry out an independent repair of the Ariston water heater.

In the mid-40s of the last century, Aristide Merloni launched the production of electric water heaters under the brand name Ariston (Successful). The name fully justified itself, and after some time all the sons of the entrepreneur successfully entered a similar business, and the youngest, Vittorio, inherited his father's company.

Today, Ariston is in the top three in terms of global sales of household appliances, and Ariston brand kitchens are sold with the main household appliances from fridge to dishwasher. In Russia, this company became famous in the late 90s of the last century, and now almost every major city has its service center.

Quality and weaknesses

Ariston water heaters have a stylish modern design, excellent functionality, and differ from analogues from other manufacturers at a reasonable price. Developers pay close attention product safety during operation: the units are equipped with various protections for all occasions, turning off the product in the event of a power failure, overheating, lack of water supply.

But this reliable technique suffers from the hardness of our water and quite frequent drops, power surges. The weakest points, according to experienced craftsmen, are tubular-type heating elements, a magnesium anode and a check valve. These very simple breakdowns can be repaired with your own hands, if you have the necessary minimum of a tool. The design of the product has a standard scheme, so prevention and repair is not difficult.

The user should pay special attention to the integrity of the internal coating, where modern materials are used, which include titanium, silver reinforcing enamels, glass ceramics and other high-tech additives.

Preparation for repair work

Before disassembling the Ariston water heater for repair, it is necessary to study the design of the product, prepare the necessary tools, as well as various devices. To eliminate mechanical damage, such as water leakage, you will need:

a set of keys or one small adjustable;
a set of various adapters;
new check valve.

In the event of a malfunction with the electrical part, it is necessary to prepare multimeter .

Preparation also includes such work: disconnecting the device from the home electrical network, draining water from the tank.

The tank in the Ariston water heater consists of the following main components:

A heating element.
Thermostat - designed to control the set temperature, as well as to adjust the heating mode.
A relay that controls the on or off of the heating element.
Special anode - it provides protection of the inner coating from corrosion.
Safety valve - regulates the internal pressure when water is heated.
Signal lights in budget models (they should turn on when current is applied) or electronics for more expensive products.

The home master should study the instructions in detail before starting preventive maintenance or minor repairs in order to freely navigate.

Main malfunctions

According to statistics, during the operation of the Ariston boiler, the following typical malfunctions may appear:

no water heating - heating element burnt out;
the thermostat needs to be replaced.
the magnesium anode has completely used up the assigned resource;
a large layer of limescale heating elements formed.

If these malfunctions occur, except for the second option, you need to completely disassemble the product.

There is absolutely no difference what volume your Ariston water heater costs - 50 or 100 liters, the dismantling process will be identical.

We make dismantling

Each owner of Ariston water heaters should know that when replacing a thermostat, relay and safety valve no need to remove the tank. Drainage of water and complete disassembly of the boiler is carried out only during maintenance work and when replacing a burned-out heating element.

Disassembly of the product is divided into standard stages:

Disconnect the water heater from the household power supply.
Drain the water from the tank.
Dismantle the flanges, gain access to the inside of the water heater.

Before disassembling the product, make sure that it is disconnected from the network. if the heater is powered by a separate line, then you need to turn off the circuit breaker, but if it’s just through the cord, then just pull the plug out of the socket.

Some readers may wonder: why emphasize these points so often? But statistics say that during home repairs or when burnt parts are replaced, very often craftsmen who neglect safety precautions receive electrical injuries of varying severity.

Only after a blackout can you start dismantling the Ariston boiler with your own hands:

unscrew the cover, which is fastened with screws;
before dismantling, take a picture of the location so as not to confuse anything during assembly;
disconnect three-core cable. the first two wires - phase and zero were connected to the thermostat, so you can carefully remove it.

All work on the electrical part has been successfully completed, you can start draining the water from the tank.

Water removal

If the initial installation of the water heater was carried out by a specialist from the service, then he had to install special tee with a drain tap and screw the fitting into it. Quite a convenient device - the user easily connects the hose, as shown in the photo, and drains it into the bathroom water. In the absence of a special device, water is removed by connecting a hose directly to the product nozzle.

Need to know! To balance the external and internal pressure, it is necessary to open the hot water tap.

Draining water can take several minutes if the heater capacity is up to 50 liters, and when you have Ariston 80 liters, the wait will take up to 30 minutes or more.

All modifications of branded productsAristonhave an oval flange on which tenes are installed, an anode made of magnesium and a tube with a thermostat inside. It is put on the flange body from below elastic rubber pad to ensure tightness. The flange is fixed with a U-shaped bar, which is fixed with a nut.

We unscrew the nut, gently push the flange inward, turn and remove it outward. Next, the replacement of failed parts and the cleaning of surfaces from salt and lime deposits are carried out.

Attention! No effort should be made when cleaning the boiler tank: over time, it becomes thinner due to corrosion. When carrying out preventive maintenance, it is advisable not to clean the fine scale.

Remove excess debris at the bottom of the tank, visually inspect the rubber seal, if everything is in order, then do not change it - it is very expensive, and it is very difficult to get a new one. Dismantling and subsequent assembly can be done independently by any user without special training. Attached is this video to help:

The statistics of the operation of similar heaters allows us to conclude: regular inspections of the wear of the magnesium anode, cleaning of the heating element, prevention of the internal coating of the tank it is necessary to do it necessarily and regularly, by doing this you significantly extend the life of the product.

Symptoms

Many models of water heaters are equipped with an electronic display, which displays different error codes. You can decrypt them using the instructions. Visually, the user can determine the following faults:

the product does not turn on - the circuit breaker has tripped;
the water is very hot - the thermostat has burned out;
streaks form at the bottom of the tank;
if when the product is turned on, the plug heats up - this is a signal that the outlet power is low.

Some users are unaware that the boiler may not turn on due to burnt contact in the socket. which indicates its low power or lack of grounding.

Causes of failure

Any failure of reliable household appliances can be provoked by the following reasons:

The formation of a large amount of scale on the heating element.
Power surges in the electrical network contribute to the failure of electronics.
Reduced water flow due to clogged filter and non-return valve.

To reanimate the equipment, you will need spare parts, cleaning the heating element and flushing the inside of the tank.

Advice! For equipment of any brand to serve for a long time and properly, do not set the temperature above 60 0 C - this significantly reduces the process of scale formation.
