How to repair an Ariston water heater yourself

Modern people find it difficult to imagine their life without boilers. In specialized retail outlets you can purchase devices from world famous companies. One of them is Ariston. Despite the reliability declared by the manufacturer, any equipment can fail for some reason. You can contact a service center or repair the Ariston water heater yourself.

You can repair this water heater yourself

About the brand

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

The Ariston company today is one of the top three in terms of global sales of household appliances, and Ariston brand kitchens are sold with already built-in basic household appliances from the refrigerator to the 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.

Ariston washing machine error codes

Error codes in the form of symbols on the screen help determine the cause of the failure.

In models without a display, a certain periodicity of indicator blinking corresponds to a particular error. Thus, the owner of the washing machine will be able to find out which unit has problems.

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 careful attention to the safety of products during operation: the units are equipped with various protections for all occasions, turning off the product in the event of a power failure, overheating, or lack of water supply.

But this reliable equipment suffers from the hardness of our water and quite frequent changes and surges in voltage. 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 fixed with your own hands if you have the necessary minimum tools. The design of the product has a standard design, so prevention and repairs are not difficult.

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

Error codes for other boiler components

A list of all possible errors, their digital designation, and decoding may take a long time. In order to more fully understand the significance of the various codes, it is worth giving a description of the most important, most frequently occurring problems with gas boilers.

• 501 - Ariston boiler error 501 indicates problems with ignition, the boiler must be reset with the RESET button. If there is no flame, the gas supply must also be checked.
• 6p1 - if error 6p1 occurs on the Ariston boiler, you need to check the exhaust system, it means that the contacts of the relay responsible for the operation of the fan have not closed in the normal way. Sometimes resetting with the Reset button helps.
• 5p3 - with error 5p3 in the Ariston boiler, flame separation from the burner was detected.
• 117 - if error 117 occurs, the Ariston boiler must be reset using the Reset button, and it should work.
• sp3 – no burner ignition. Found in models with the EGIS Plus index and the like. Sometimes it is interpreted as flame separation, which makes it possible to classify the sp3 code as the most critical error.

Particular attention should be paid to problems such as flame separation. It occurs due to too powerful a gas flow and can lead to gas contamination inside the boiler. The same error in the Ariston 501 or 6p1 boiler does not cause any special problems, except for the inability to turn on water heating

Error - flame separation in the Ariston boiler may indicate serious problems in the supply system, they cannot be solved on your own, you just need to call a specialist, having first turned off the gas supply

The same error in the Ariston 501 or 6p1 boiler does not cause any special problems, except for the inability to turn on the water heating. Error - flame separation in the Ariston boiler may indicate serious problems in the supply system; they cannot be solved on your own, you just need to call a specialist, having first turned off the gas supply.

When a flame breaks out, a fire hazard arises, so if it occurs frequently or at least systematically, you should consider checking the gas supply line. The accumulated gas in the boiler can flare up and cause mechanical damage to it or even create a health hazard for people living in the apartment.

In addition, heating efficiency decreases significantly and gas consumption for the same volume of water increases. The flame power should be adjusted smoothly, without popping inside the boiler and other abnormal phenomena and sound effects. Only then can you expect economical operation from the heater.

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 accessories. To repair mechanical damage, such as water leaks, you will need:

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

If a malfunction occurs with the electrical part, you need to prepare a multimeter.

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

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

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

The home handyman should study the instructions in detail before starting maintenance or minor repairs in order to be able to navigate freely.

The lineup

The Ariston brand produces many models of water heaters. Positive customer reviews clearly prove that this brand is number one in the market for the production of gas appliances. The Ariston Fast Evo model is the most popular of the entire line of heaters. The model is available in two types, differing in productivity (11 and 14 liters per minute). This is a turbocharged automatic car with electric ignition. To operate the device you only need two batteries. In addition, the model has a built-in flame modulation system. Such a system allows you to maintain temperature constancy.

The main advantages of Ariston Fast Evo include:

• ability to work at two water intake points;
• ignition occurs at minimum pressure;
• optimal outlet temperature.

Another popular model is part of the Marco Polo series - Gi7S with a closed combustion chamber. The device is equipped with a flow-through heater and does not have a chimney. An important feature of the device is that the pipe is led outside, therefore, combustion products do not remain indoors, but go outside. Gi7S is the most powerful unit, therefore it is very energy-consuming. Among the more budget models, Ariston CA 11P is in particular demand. The unit has a classic design and is easy to operate. It stably maintains the set parameters and does not upset the settings.

Basic faults

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

• no water heating - the heating element has burned out;
• The thermostat needs to be replaced;
• the magnesium anode has completely used up its assigned resource;
• A large layer of limescale from heating elements formed.

If these malfunctions occur, in addition to the second option, you need to completely disassemble the product.

There is absolutely no difference what size Ariston water heater you have - 50 or 100 liters, the dismantling process will be identical.

How to choose the right mechanism

Heating element for Ariston boiler
How to read the designation of the heating element, for example, heating element - 32 A 13 / 1.5 J 220 where:

• TEN – tubular electric heater.
• 32 – expanded length of the heating element along the shell.
• A – designation for sealing the contact rod.
• 13 – diameter of the heating element shell.
• 1.5 – rated power in kW.
• J – designation of the heating medium and heating element material
• 220 – rated voltage in V.

If you follow the markings, you can find the right model quickly and without unnecessary nerves. And for this you don’t need to walk around with a centimeter or carry a broken product with you. It will be enough to compare the data on your heating element and the one you are going to buy.

When choosing a heating element for an Ariston boiler, you should pay attention not only to the price, but also to the design differences. It is also necessary to take into account the operational characteristics of electric heaters

Having a stable voltage and proper operating conditions, a “wet” heating element will last on average 5 years, and a “dry” one – 15.

The company recommends purchasing equipment for replacement in factory-made water heaters and according to the existing model of the unit.

Heating elements with a power of 1.5 kW are more common for Ariston boilers. They are often used in equipment with a volume of both 20 liters and 100.

Engineers categorically do not advise replacing a low-power heating element with a more productive one, since the water in the equipment heats up to 85 degrees and the boiler turns off. And high power disrupts the operation of the device and increases the cost of each water heating.

When choosing a heating element, you should also pay attention to the flange. Threaded - thanks to the existing thread, the heater is attached to the boiler by screwing

The thread diameter is 1 1/4 inches. Clamping ones - come in the following diameters: 62 mm, 72 and 82 mm.

For dry heating elements - they are made of enameled metal, almost always in pairs, and have closely spaced contacts with a “petal” type fastening.

We carry out dismantling

Every owner of Ariston water heaters should know that when replacing the thermostat, relay and safety valve, dismantling the tank is not required. Draining the water and completely disassembling the boiler is carried out only during maintenance work and when replacing a burnt-out heating element.

Disassembly of the product is divided into standard stages:

1. Disconnect the water heater from the home electrical network.
2. Drain the water from the tank.
3. Remove the flanges and gain access to the inside of the water heater.

Before disassembling the product, you need to 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 a cord, then simply pull out the plug from the socket.

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

Only after turning off the power can you begin dismantling the Ariston boiler with your own hands:

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

All electrical work has been successfully completed, and you can begin draining the water from the tank.

Removing the thermostat

Removing water

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

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

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

Hose with fitting

Opening access inside

All modifications of products under the Ariston have an oval flange on which heaters, a magnesium anode and a tube with a thermostat inside are installed . An elastic rubber gasket is placed on the flange body from below to ensure tightness. The flange is secured with a U-shaped strip, which is secured with a nut.

We unscrew the nut, carefully push the flange in, turn it and pull it out. Next, the failed parts are replaced and the surfaces are cleaned of salt and lime deposits.

Attention! Do not make any effort when cleaning the boiler tank: over time it becomes thinner due to the effects of corrosion. When performing preventive maintenance, it is advisable not to clean off thin 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. We attach this video to help:

The operation statistics of similar heaters allows us to conclude: regular inspections of the wear of the magnesium anode, cleaning of the heating elements, and preventive maintenance of the internal coating of the tank must be done regularly and by doing this you will significantly extend the service life of the product.

Do-it-yourself water heater cleaning

Any Ariston boiler needs periodic descaling. Experts recommend doing this regularly (once or once a year and a half). 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. It is not difficult to determine that the moment has arrived

Just pay attention to the obvious changes:

• an uncharacteristic hissing appeared when heated;
• heating time has increased;
• The boiler began to turn on and off more often.

Despite the high quality of parts of Ariston boilers, standard maintenance of any model will not be difficult even for beginners. If you have free time, obedient hands and enough patience, then you don’t have to spend your personal budget on specialists; you can repair the water heater yourself. Review the following simple maintenance procedures:

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

2. Proceed to draining: select a hose whose diameter is several 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. Place the free end of the hose into the sink, bathtub or toilet.

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

4. While continuing to repair and clean the Ariston boiler yourself, remove the heating element (it is usually secured with a nut on a metal plate). After removing the water heater from its mountings, carefully pull out the thermostat. To make it easier to remove the heating element, push the flange inside the heater, then try to pull it out.

5. In the hole you will see scale that has formed, which will need to be removed, which can be done simply with your hands or a technical rag with a product that neutralizes limestone deposits. But under no circumstances use abrasive materials, this will have a detrimental effect on the surface of the device. If there is no special product in the house, use a proven folk method: dilute citric acid in water, pour it into the Ariston water heater tank and let it sit for a day.

After the procedure, rinse the water heater tank with a stream of clean water to remove any remaining scale. The heating element is cleaned in the same way: immerse it in a solution of citric acid for 1 day. 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 original anodes from the manufacturer for each individual Ariston water heater model.

6. Next, in the maintenance order, you only need to put all the dismantled parts in their places, pour water into the Ariston boiler, connect electricity and water supply to it.

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 phase and zero! Use an indicator screwdriver to identify these pins. If you have forgotten how the boiler was originally connected, refer to the diagram shown on the thermostat.

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

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

Symptoms of a problem

Many models of water heaters are equipped with an electronic display on which various error codes are displayed. You can decipher them using the instructions. Visually the user can identify the following faults:

• The product does not turn on - the circuit breaker has tripped;
• the water is very hot - the thermostat has burned out;
• drips form in the lower part of the tank;
• if when the product is turned on, the plug heats up - this is a signal that the power of the socket is low.

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

Adviсe

When purchasing an Ariston water heater, a warranty is provided for the device. If the device fails during the warranty period, it is better to entrust the troubleshooting to specialists, since the repair will certainly be carried out efficiently and free of charge.

Scale inside the tank is formed most actively from exposure to high temperatures. When operating the device, it is recommended to heat the water to 60 degrees.

Not everyone needs to use a water heater all the time. When the device is not planned to be turned on for a long period of time (more than a week), it is necessary to take care of the water in the tank. If you do not drain the water from the container, this will lead to the spread of microorganisms inside the tank and an unpleasant odor that will be difficult to eliminate.

It is also not recommended to completely empty the boiler. An empty tank, despite the protective anti-corrosion coating, may begin to rust. The most suitable option in this case would be to periodically (a couple of times a week) refresh the water in the device by turning on the boiler for a few minutes.

When installing the boiler, you must perform all actions in accordance with the instructions. If installed incorrectly, the device may quickly fail. If any malfunctions are detected in the operation of the device, it is not recommended to operate the water heater until the breakdown is eliminated.

Causes of failure

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

1. Formation of a large amount of scale on the heating element.
2. Voltage surges in the electrical network contribute to electronic failure.
3. Water flow decreases due to clogged filter and check valve.

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

Advice! In order for equipment of any brand to serve for a long time and properly, do not set the temperature above 600C - this significantly reduces the process of scale formation.

Let's get acquainted with the boiler design

To understand how to ensure many years of uninterrupted operation of the purchased unit, you need to at least have a rough idea of ​​its structure. It would also be a good idea to read the instructions for this model. This will allow you to avoid making mistakes when using an electric water heater.

A diagram suitable for most manufactured water heating devices is shown in the picture below:

Schematic design of a storage water heater

All water contains some amount of dissolved salts and minerals. With frequent heating and cooling, these salts crystallize and settle on the inner walls of the tank in the lower part. In 2-3 years, not only the walls are covered with a strong shell, but also the heating element and the copper tube, inside of which the temperature sensor is inserted. To reduce the hardness of the formed slags and to prevent corrosion of the tank body, a magnesium anode is attached to the same flange with the heating element. But it is not designed to last long, so it needs to be changed from time to time.

If you disassemble a boiler that has worked for several years without cleaning, you will see the following picture:

Scale formed due to long-term use of the Ariston boiler

This situation is scary not only because of its appearance. Such a frivolous attitude towards a water heater can lead to the following consequences:

1. With such an amount of scale, energy consumption when heating water increases.
2. Due to the higher temperature in the operating area of ​​the heating element, the temperature sensor or heating element fails.
3. The magnesium anode completely fails and, naturally, requires replacement.
4. The risk of corrosion of the tank body increases many times over, causing water leakage. In this case, replacing the device with a new one is inevitable.

In order not to take matters to such an extreme, almost all companies that produce electric water heaters recommend maintenance of devices once every one to two years. What is it? It is necessary to disassemble the water heater, replace the magnesium anode with a new one, check and, if necessary, clean the heating element, clean and rinse the inner surface of the tank with water. If such an event is carried out regularly, the service life of the boiler can at least double.

Replacing the thermostat

To replace the thermostat, follow these steps:

1. Remove the fixing ring (clamping) near the heating element.
2. Remove the sensor adjustment unit and the thermostat itself.
3. Install a new element.
4. Secure it with a clamping ring.
5. Check the condition (position) of the safety valve.

Please note that after replacing the thermostat, it is not recommended to immediately start operating the device! Check that cold water is flowing correctly inside, check that the connecting element does not hiss. The hot tap is then opened to release any air that has accumulated inside the boiler. Only after this can a test run be carried out .

Boiler service menu

For all manipulations with switching modes, only 4 buttons are used - Plus, Minus, Ok/Menu, ESC.

It is important to understand that not all boiler menu items will be available to you; some of them will only become available when additional devices are connected to the boiler, such as external sensors or a solar collector. And most menu items are accessible only by service code, I’ll talk about this below, but for now, “let’s practice on cats.” And most menu items are accessible only by service code, I’ll talk about this below, but for now let’s “practice on cats”

Interesting!

History knows the fact that a kitten fell into the drum of a washing machine and, after going through a full wash cycle on the “Wool” program, got out of the unit unharmed. The only trouble for the pet was an allergy to washing powder.

Features of the Margarita 2000 repair

This model was sold back in the 2000s, but you won’t see it on store shelves for a long time. However, in some families it still serves faithfully. Despite the outdated design, the model has a standard design.

There are some nuances during dismantling - the powder receiver of this washing machine does not extend forward, but rotates 450 degrees clockwise, so in addition to the standard two horizontally inserted screws, it is held in the desired position by another vertical one.

Margarita 2000 has a mechanical control; when a malfunction is detected, the command device begins to rotate clockwise. The frequency at which the “On/Off” indicator lights up will help you navigate current malfunctions.

The number of blinks forms an error code, for example, 3 blinks in a row corresponds to F03, two blinks – F02, etc. The pause between series is 4 seconds.

The model is far from new, so its main malfunctions are associated with long-term operation: wear of the electric motor brushes, failure of bearings, inlet valve, drain pump, heating element.
