F12 error in Whirlpool washing machine

The Whirlpool laundry machine indicates a problem with water heating by flashing code F12 on the electronic display. For devices without a display, you can find out about the problem by signal lights. If the water is not heated, the third, fourth and ninth signal indicator will light up on the control unit. Has your washing machine stopped heating water, so you can't wash your clothes properly? In this case, you should immediately contact the master from the service center. He will diagnose, identify the problem, and restore the robot to the washing machine.


When the washing machine stops heating water, an error code F12 will be displayed on the screen. You need to figure out what caused this failure. To do this, diagnose the following parts of the mechanism:

  • Heating element - it can burn out or pierce the case, so you need to change it,
  • Electrical wiring connecting the heating element and the electronic control unit - if it is disconnected, restore it,
  • Thermostat - make sure that it is working, if it is not, you will need to install a new part,
  • Relay - located on the electronic control unit, in case of a malfunction, this spare part must be changed.

All work related to the electronic control unit requires certain knowledge and experience, so it is better to contact a service center for help. If you have any questions or want to call the master, call us (order a call back).
