Why the heater breaks down

Heating water in the stylalk is very important, because in hot water, things are washed efficiently and efficiently. But, unfortunately, the service life of the heater is 3-5 years.

There are several reasons why an element fails:

  • Natural wear. The element constantly heats up and cools down, which shortens its service life.
  • Scum. Unrefined water contains impurities of salts that do not dissolve and settle on the surface of the heater. The thicker the scale, the more difficult it is for the TEN to transfer heat. As a result, it overheats and burns.

  • Voltage drops in the network can lead to a short circuit. It, in turn, leads to the breakage of the heater circuit, the breakdown to the housing.
    Also, the reason that the element does not work can be the combustion of a triac on an electronic board. The triac is responsible for the operation of the heater, so if it fails, the heater does not receive a signal to operate.
    Then you will need to replace or repair the heating element in a Bosch washing machine.

For prolonged operation of the heater it is recommended to use emollients or install a water filter.
