The water heater does not turn on, the buttons do not work - what to do about it?
The water heater does not work, I turn on the button, all the lights on the buttons blink at once, it does not heat. Help at least with advice. What could it be? What is the problem?
If there is an electronic control board, it is likely that the problem is in it. If there is no board, look at the quality of the contacts and ring the buttons as they work. Also inspect all the wires - maybe some close to the case.
