Repair of water heaters Ariston with electric and gas heating

Ariston water heaters are electric and gas. Repairing Ariston heaters with a gas burner is different from troubleshooting an electric boiler. Combines the models with a storage device, water piping and a special valve that acts as a bypass and return valve. The electronic control system is designed for both energy sources, but in the event of a failure, it can only be adjusted by specialists.

How to keep the tank from corrosion and destruction

The tank consists of an inner tank, a casing and a spacer between them in the form of foamy heat-insulating material. The inner tank Ariston is necessarily made of stainless steel, connected by special welding, which does not change the structure of the metal. Enamelled inside. And now you need to remember whether it is possible to heat a dry enamel pot, whether it is possible to cook if the enamel bounced off, and when it happens. A boiler is much more expensive than a pan, repairing the body of an Ariston water heater is difficult, so you need to do:

• inspection of the integrity of the body from the inside and outside when buying a boiler;
• installation strictly according to the instructions without distortions during installation;
• use special factory-made valves;
• no fittings on the nozzles of the security system can be installed;
• safety automatics must not be disabled.

It is worth heating the boiler once without properly filling it with water and microcracks may appear in the enamel coating, through which metal corrosion will occur and fistulas will appear in the body. The reason is only careless use of the equipment.

Whether it is necessary to rid the walls of scale, the recommendations of experts differ. Some people believe that scale on the walls is a protective layer and additional thermal insulation of the walls. Others recommend dissolving and removing the sediment annually with weak organic acids. But everyone agrees that it is unacceptable to use abrasive materials to remove sediment, you can scratch the protective layer. When repairing the Ariston water heater, clean the tank from dirt and thoroughly rinse the attachment points of the internal equipment.

Repair of electric water heaters

An electric water heater requires repair if:

• when the plug is connected to the outlet, the voltage supply indicator on the boiler does not light up;
• the light comes on, but the protection is activated;
• the water in the tank does not heat up;
• the device does not respond correctly to commands.

If you have a heater with an electronic control system, if there is a power outage in the network, the unit will lose the program. Only a specialist can restore it. The service center carries out any repair of storage water heaters, if the device is under warranty. Unauthorized interference will void your warranty!

First you need to ring the feed scheme. Make sure that the mains voltage is present, the fuses are in working position, the cord, the plug are working. There you also need to check the serviceability of the RCD, the device is located in front of the plug.

You can descale the heating element using acetic, citric, oxalic acid or Antiscale by leaving the element in warm water for several hours. But at this time, the gasket must be removed, it loses its elasticity in the solution.

After you need to open the panel installation of heating elements and electrical connections.Check the condition of the element by ringing the terminals. The resistance should be 13.5 Ohm for a kilowatt, for higher power, the value is directly proportional to the given one. If the heating element passes an electric charge, then the thermostat must be checked. It is checked for contact actuation at room temperature and at 60⁰ C. But to check the thermostat, it is necessary to dismantle the assembly. Step by step it looks like this:

• fix the position of the connected wires on paper or in a camera;
• disconnect the wiring;
• remove thermoelements;
• remove the magnetic anode, inspect it, clean it from loose build-up; if the material is badly worn out, replace it;
• unscrew the bolts and remove the flange with the installed heating element, release the heating element, clean it and inspect it for cracks;
• check the condition of the thermostat;
• clean the tank and flange connection;
• after repairing the water heater with your own hands, replacing the unit, assemble and fix the parts in the reverse order.

Attachment of any flange on any device by bolts is performed with successive tightening of opposite nuts. Then the tightening is smooth and there will be no leakage through the seal.

In order to avoid electrochemical corrosion of the tank, in addition to the magnesium electrode, you must have a full-fledged ground loop, which is also needed for your own safety. RCDs and grounding have different tasks.

Gas boiler repair

Gas water heaters produced by the Italian company Ariston are large, the smallest is designed for 180 liters and is installed on the floor. They are adapted to changes in pressure in the gas supply, water networks. Repairs gas water heaters Ariston do it yourself is not welcome. Safe operation of the column depends on the correct removal of combustion products and the absence of leaks of unburned natural or liquefied gas.

Repair is required in cases;

• no water comes from the storage;
• poor draft, and there is a smell of gas in the room;
• there is no flame.

Maintenance includes periodic lubrication of control valves, moving stems. Before work, it is necessary to close the main valve, and then check with soapy water for leaks all the units of the flue. When switching from LPG to main gas, it will be necessary to change the pilot burner nozzle and the water valve.

To keep the radiator with clean tubes for a long time, you need to heat the water no higher than 45 degrees. At this temperature, hardness salts are in a dissolved state.

Pay attention to the use of plastic pipes and flanges when tying. This protects against stray currents and accidental sparks.

Diagnostics of the causes of a malfunction of the gas accumulator is simple:

• scale has appeared in the heat exchanger, which is an insulator and reduces the nominal bore of the tube - the water pressure is low and it is poorly heated;
• the radiator is flowing - the water does not heat up;
• the burner may not ignite if there is no gas in the line or if the supply hole is clogged;
• the water temperature is lower than the set one - check the regulation system.

Often the malfunction is manifested by clogging of the radiator. The tank is muted, the radiator is left in place, but filled with a descaling liquid. You can periodically warm up the tubes with an igniter. When draining the chemical, limescale must be flushed out.

If the heat exchanger leaks, you can solder it at home, like using a flux rosin. In addition, you can clean the chimney with your own hands, buy new batteries for the ignition system. Elimination of other malfunctions should be entrusted to the specialists of the gas service.
