Water heater "Termex" 80 liters - repair by own hands

A domestic water heater is an irreplaceable thing in the house, and its breakdown deprives us of the usual amenities. Unfortunately, budget models often fail, and the owners have a natural question: can I repair the device myself, call the master or drag the tank to the service center. Let's try to deal with the typical breakdowns of the "Termex" boiler, which will allow to optimize the costs. Theme of the article: water heater "Termex" 80 liters - repair by own hands.

How does the boiler work?

The body of the water heater, at first glance, looks quite impressive, but in fact the principle of operation of the device resembles an ordinary electric kettle. Its main components are a thermostat and an electric heater of a tubular type, placed in a housing. There is also a magnesium anode, which often goes out of order. TEN - this fechral wire, located inside a copper pipe with a filler made of dielectric.

Water from a water pipe is an excellent medium for the exchange of ions between a copper sheath and other metal parts of the tank. In fact, water gradually destroys the metal parts of the boiler. To slow these processes, the tank has a magnesium rod. In fact, it is used as an ion donor. When the rod is destroyed over time, the metal walls of the tank are corroded.

Important! The disadvantage of "Termex" tanks is that a minor scratch is enough to make the corrosion happen. The surface of the donor rod is small here.

Before we talk about the possibilities of repairing the water heaters "Termex" with our own hands, we will find out the following nuances.

When should I contact a specialist?

• The tank is under warranty. When contacting a service center, do not remove the label. This may be the reason for refusal of free repair.
• Tripping of emergency shutdown in the new device. This defect is typical for small-scale "Termex" boilers. Only a specialist can help here.
• The settings in the thermostat failed. The electronic "stuffing" of the device sometimes resets the settings when the power is suddenly cut off.

Important! As a rule, repair of a water heater in a service center is not a cheap pleasure. The cost of repair and diagnostics on average costs about 30% of the cost of the boiler. Avoid expensive repairs can be, if you install the boiler correctly and take anti-corrosive measures in time.

When is tank repair required?

The first sign of a malfunction of the appliance is the lack of water heating or very weak heating. You will need to repair the device in the following situations:

• There is no signal to supply power, there is no current in the electrical circuit.
• There is power, the indicator lights, but there is no heating of water. This indicates a breakdown of the ten.
• Thermostat failure.
• The appearance of fistulas or leaks.
• Anode wear.

Important! For self-repair will not be much: a spare TEN with gaskets in the kit, seals and a magnesium electrode. To untwist the fasteners, you will need the keys. To clean the heater from scaling, you will need a brush.

Repair algorithm, or how to disassemble the "Termex" water heater for repair by one's own hands:

1. If no power is supplied, check the electrical socket and the integrity of the electrical circuit as a whole. The reason can be a power outage. The current indicator and elementary attentiveness are your best assistants in a similar situation. The cause of power failure can be: blocking from "dry" switching, poor insulation, triggering of RCD.
2. Water does not heat up. To check the heater, remove the cover. This will give you access to the TEN terminals. Now, using a tester, check its serviceability. If there is a voltage on the terminals, but the heater does not heat, you need to change the heating element. To do this, disconnect the wires, remove the thermal sensors and unscrew the connection of the platform with the heating anode and TEN.Simultaneously with the replacement of the heater, it is advisable to clean the magnesium electrode or replace it.

Important! Before disconnecting wires, save the order of the wires on any medium. This will help you avoid errors when connecting.

1. If the tank started leaking, then, most likely, the problem is a breach of the integrity of the gaskets. Replace them or rewind on flange connections. Sometimes a leak occurs after the replacement of TEN.In this case, reinstall the heating element. If the leakage is caused by corrosion of the storage tank, the device can not be repaired.
2. Does the water not heat up when the heater is in good condition?it is recommended to check the serviceability of the thermostat.

Care and prevention of breakdowns

Rigid water is the worst enemy of hot water appliances. Salts of calcium and magnesium contained in tap water, contribute to the appearance of sediment on the surface of the TEN.Therefore, the heater should be cleaned once a year with a solution of citric or acetic acid, which destroys the sediment.

A good preventative measure against the appearance of scale is the use of special water softeners. In addition, a mandatory measure is the installation of a filter on the water supply line to remove particulate matter in suspension. If you correctly set up prevention, then the question of how to clean the water heater "Termex", will not worry you often.
