The main part of the water heaters is arranged according to a similar scheme.After conducting technical diagnostics, an experienced master can easily calculate the source of the problem and correct the situation. In addition, the failure of these devices are typical, the same problem pursues the units of different companies.

Wiring problems

The boiler may stop turning on after serious damage to the connecting wiring. Without it, the coordinated functioning of individual parts of the system, and even the launch of the main process, is impossible. Even poor contact with TENA terminal causes a shutdown effect. You can identify this problem with a special tool - a tester. It determines the permeability of electric current on the terminals.

Breakage of heating elements or electrification of the case

One of the main parts of the boiler that performs water heating is heating elements. A failed heating element causes the entire device to stop working. To identify failures will have to measure resistance. The procedure is carried out using a special tester. In the case of heater integrity, a certain value will appear on the display, if the part is faulty, the value will remain at zero.

In addition, a healthy at first glance heaters can redirect electricity to the body of the water heater and cause RCD trip. The safety device simply prevents the boiler from switching on to prevent short circuits and protect users from electric shock. It is possible to reveal malfunction by the same tester.
