How to repair a water heater Ariston yourself

Today, different types of heaters are very firmly established in our modern everyday life. In specialized stores offer products from companies of world brands c very widely known, for example, such as Ariston. Despite the high reliability, any household appliances may eventually fail for any reason. In this case, it will be useful to know how to carry out an independent repair of the water heater Ariston.

About brand

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

Ariston today is in the top three in terms of global sales of household appliances, and Ariston kitchens are sold with already built-in basic household appliances from the refrigerator to the dishwasher. In Russia, this company became known at the end of the 90s of the last century, and now almost every major city has its service center.

Quality and weak points

Ariston water heaters have a stylish modern design, excellent functionality, differ from their counterparts from other manufacturers at a reasonable price. Anxious attention is paid by developers product safety during operation: units are equipped with various protection for all occasions, disconnecting the product in case of power failure, overheating, no water supply.

But this reliable technique suffers from the hardness of our water and quite frequent drops, surges in tension. According to experienced craftsmen, the weakest points are tubular-type heating elements, magnesium anode and non-return valve. These very simple damage can be fixed with your own hands, if there is a necessary minimum of the tool.The design of the product has a standard scheme, so the prevention and repair is not difficult.

The user should pay particular 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 dismantling the Ariston water heater for repair, it is necessary to study the product design, prepare the necessary tools, as well as various accessories. To repair 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 case of malfunctions with the electrical part, it is necessary to prepare multimeter.

Preparation includes the following works: disconnecting the appliance from the home electrical network, draining 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. Relay, which controls the on or off the heating elements.
4. Special anode - it protects the internal coating from the effects of corrosion.
5. Safety valve - regulates the internal pressure when heated water.
6. Signal lights in budget models (they should turn on when current is applied) or electronics for more expensive products.

A housemaster should study the instructions in detail before starting a prevention or minor repair in order to navigate freely.

Main malfunctions

According to statistics, during the operation of the Ariston boiler, such typical malfunctions can occur:

• no water heating - burned out heating element;
• thermostat replacement required;
• the magnesium anode completely consumed the assigned resource;
• formed a large layer of lime scale tenov.

In the event of these faults, except for the second option, you need a complete disassembly of the product.

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

Ariston Water Heater Thermostat

We make dismantling

Every water heater owner Ariston should know that when replacing a thermostat, a relay and a safety valve no disassembly of the tank is required. Water is drained and the boiler is completely disassembled only during maintenance work and when replacing a burned-up heater.

Product disassembly is divided into standard steps:

1. Disconnect the water heater from the household power supply.
2. Drain the water from the tank.
3. Remove flanges, access the inside of the water heater.

Before you disassemble the product, you must make sure that it is disconnected from the network: if the heater is powered by a separate line, then it is necessary to turn off the circuit breaker, if just simply through the cord, then just pull the plug from the outlet.

Some readers may wonder: why so often to emphasize these points? But the statistics asserts that when doing home repairs or when replacing burned-out parts is made, very often the masters who neglect safety precautions get electrical injuries of varying severity.

Only after de-energizing, you can begin dismantling the boiler Ariston 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 - the phase and zero were connected to the thermostat, so you can carefully remove it.

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

Removing the thermostat

Water removal

If the initial installation of the water heater was performed by a master from the service, then he should have installed special tee with tap and drain screw in it fitting. 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 the 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.

Drain water can last a few minutes, if the heater capacity is up to 50 liters, and when you have Ariston 80 liters — waiting will last up to 30 minutes or more.

Hose with fitting

Open access inside

All modifications of products under the brand Ariston They have an oval flange on which the heaters are installed, an anode from magnesium and a tube with a thermostat inside. At the bottom of the body flange worn elastic rubber gasket to ensure tightness. The flange is fixed with a U-shaped strap, which is fixed with a nut.

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

Attention! You can not make an effort during cleaning the tank capacity: over time, it becomes thinner due to the effects of corrosion. When conducting preventive maintenance, it is advisable not to smooth out the scum.

Remove excess debris on 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. To help enclose this video:

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

Symptoms

Many models of water heaters are equipped with an electronic scoreboard, which displays different error codes. You can decipher them using the instructions. Visually, the user can identify such faults:

• the product does not turn on - the automatic protection has worked;
• the water is very hot - the thermostat has blown 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 outlet is low.

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

Causes of failure

Any failure of reliable household appliances can provoke such reasons:

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

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

Tip! To make the equipment of any brand serve for a long time and regularly, do not set the temperature above 60⁰C - this significantly reduces the formation of scale.
