Why the water heater can not turn on

The use of household appliances is sometimes fraught with unpredictable difficulties. An ordinary person is not always able to immediately understand the causes of a given failure. It is especially difficult for people who do not often deal with repairing equipment: without receiving a special education, it is difficult to say why, for example, the water heater does not turn on.

Common causes of boiler breakdowns

What could cause such a breakdown? How to diagnose and accurately identify the cause of the problem in the boiler? Assign the search for answers to these questions better professional repairman. After all, they are often accompanied by complete external well-being of the device, without any noticeable defects.

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.

Check of TENA

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.

A failed heating element cannot be repaired - it is a consumable item subject to normal wear and tear.

Thermal protection

This feature is provided to prevent overheating by opening an electrical circuit. It works when the temperature rises above ninety degrees. Causes a similar reaction thermal sensor breakage or scum formed over the years. You can remedy the situation by cleaning the heating element with a solution or turning off the thermal protection.

Breaker outlet

It happens that the outlet from which the boiler is powered ceases to produce enough voltage or is simply incompatible with the device - this is a trivial reason that your boiler did not turn on. In the first case check the operation of the outletby connecting to it another device. Replace your outlet with a new one, or move the boiler to another location.

Remember that you can not connect devices to outlets that are not designed for high voltage - this can lead to a short circuit or breakdown of the unit. Among other things, consider the state of the house wiring, because such a powerful electric device will put a serious load on it.
