Water heater Ariston 80 liters - repair by own hands

The Ariston water heaters are very popular due to the reliability and simplicity of the device. The device not only provides the user with heated water, but also to some extent improves the consumer quality of water.

Flow and storage water heaters differ, depending on the volume of the tank. Models with a tank of 100 and 80 liters fully meet the needs for hot water for a large family. Models with a tank of 50 liters have an optimum ratio between the volume of heated water and the consumption of electricity. Using this tank, you can use the shower for 10-15 minutes. Kitchen boilers are equipped with mini-tanks with a capacity of 15-30 liters and are mainly used for washing dishes.

The range of water heaters is constantly improving, but even the most modern protective systems do not save from breakages. The reasons for the occurrence of malfunctions are many: water pressure drops, power surges, failure of electrical components and other components of the device, improper operation of the device and lack of prevention. Theme of the article: water heater "Ariston" 80 liters by own hands.

Features of water heaters and main causes of faults

Hot water boilers "Ariston" correspond to protection against moisture and dust according to the international scale from IP24 and above. This means that breakdowns from mechanical influences are rare. The design is reliably protected from dampness. Only purposeful vandalism can disable the device.

Important! One of the main design features is the use of a protective casing in stainless steel with enamel coating or with external thermal protection.

The devices use 1-2 heaters for main and accelerated heating. As a rule, "Ariston" boilers are equipped with:

• Silver-containing coating, an eco-protection system against microorganisms for water disinfection.
• An increased magnesium anode, which helps to purify water and protect the tank from corrosion.
• The system of water distribution in the tank "Nanomix" and the built-in heat pump of recirculation.
• Electronic or bimetal thermostat with temperature control up to 80 degrees.
• Thermal insulation of the outer walls of the tank - polyurethane foam.
• The system of protective shutdown and electrical safety.

Mechanical faults and their elimination

If the repair of the gas appliance requires the intervention of a qualified technician, then the home builder can also repair the boiler or electric column.

Important! It is hardly worthwhile to undertake the repair of the Ariston water heater 80 liters by oneself, if the warranty period has not been worked out. The cost of the boiler when buying includes and repair from the specialists of the service center with a visit to the house.

Frequent problems:

• The most common mechanical faults are tank leaks. Water drips or seeps. Before selling the tank passes a special test. Its walls with a thickness of 0.6-1.0 mm are able to withstand a pressure of 16 bar. But over time, the material from which the tank is made is corroded. For this reason, it may occur through the outer coating of polyurethane or metal walls.
• Another reason for the mechanical failure of the device is the inflation of the tank due to the failure of the safety check valve. Infringement of the sealing of the inner tank is the most costly of failures, since in some cases the device is not repairable and a new tank needs to be purchased.
• Much easier if leakage is observed at the bottom of the device( for example, in the place of the flange connection of the TEN).In this case it is enough to replace the gasket with a better one. For example, from foamed rubber or from autoclave rubber.

Classification of electric breakdowns of

These are the least expensive faults for "Ariston" boilers. The most vulnerable in the "Ariston" boilers are the following elements:

• heating elements.
• Switches and sensors.
• Bimetal thermostats.

Important! To avoid the breakdown of electrical components, experts do not recommend connecting the cabinet and zero slots, because this turns off the protective system, which responds to a short circuit or a leakage current. Grounding in the device is initiated by a separate insulating wire.

The lion's share of all electrical faults is in the heater. Occurrence of hiss or noise, prolonged heating of water, activation of a protective shutdown system - all this indicates that the heater has failed or its flask has become covered with scale. The average heater is about five years.

Important! It is necessary to periodically check the state of the magnesium anode. Despite the "electrical" name, the anode is not connected to the electrical circuit, but effectively protects the heating element and the tank itself from corrosion. If the anode is thinned by 50%, this serves as the basis for its replacement.

To assess the state of the heater, you need to measure the resistance on its knife blocks. If it goes off "to infinity", it is a signal to replace it. If the heater is OK, then:

1. Its performance can be restored by immersing the heating element for 24 hours in a solution of citric acid( 50 g of citric acid powder per liter of water).
2. Simultaneously wash the tank of mineral salts and scale.

After the new heater is installed, measure the resistance between the housing and the output terminals( its value should be no less than 24 ohms).The heating element will last longer if you install a "dry" heating element.

Preparing to repair the Ariston water heater 100 liters with your own hands

Before you start repairing the water heater, you need to prepare tools and accessories. To eliminate water leaks will be needed.

• Set of adapters.
• Adjustable wrench.
• Check valve.
• If the boiler of the water heater fails, a welding machine is required.

Important! To eliminate electrical faults, in addition to tools, an ohmmeter or tester is required. Before repair, it is necessary to drain water from the tank, and disconnect the electrical part from the apartment power supply network.

How to repair

Consider the most likely malfunctions related to disturbances in the water supply system and its heating to the required temperature, we will figure out how to disassemble the Ariston water heater 80 or 100 liters.

Water leaks from the

tank The algorithm for repairing the Ariston water heater with one's own hands is as follows:

1. Inspect the hoses for water supply and drainage.
2. If the hoses work, then inspect the bottom of the drive capacity.
3. Disconnect the boiler, remove the bottom cover and the thermostat. Remove the thermal insulation located at the bottom of the tank.
4. If leakage is detected at the connection points, install a sealant, additional seals.
5. If the storage capacity is out of order, welding work will be necessary.

Important! You can use "cold welding", but this will not give the desired effect for a long time.

The water in the storage tank does not heat up

First of all, check the presence of 220V voltage in the network. If there is voltage, then it is advisable to check the serviceability of the thermal electric heater( TEN):

1. Using a tester or an ohmmeter, check the serviceability of the cable with which the boiler is connected.
2. If the cable is OK, measure the DC resistance of the heater.
3. If there is no instrument reading, replace the TEN.

Important! Sometimes the resistance measurements correspond to the operating state of the heater. In this case, the water does not heat up due to a malfunction of the thermostat, and it needs to be replaced.

After repair

Regardless of which fault has been eliminated, the tank must be cleaned of debris and scale. Before you plug the tank into the mains, make sure the parts dry up to avoid a short circuit. When connecting the tank, do not forget to ground the storage tank.

As you can see, the work on the repair of an electric hot water boiler is not very difficult, and with them the master with minimal knowledge can quite cope. Nevertheless, if you doubt your own abilities, it is better to leave this work to a specialist, so as not to disable the equipment completely out of order.
