Re: Hotpoint Ultima washer dryer not heating and no code
It doesn’t have any thermostats, and the two systems are separate. The temperatures are controlled by NTC’s or thermistors which do not stop the heaters from working, they basically just control the temperatures.
If you have access to a suitable multimeter or better still a megger then the first thing to do is to check both elements electrically.
It is possible that the wash heater failed months ago and now the dryer heater has failed but you should have noticed some problems with the programmes when or if the wash heater failed.
