Re: hotpoint DWF50P NO HEAT
I fitted a new relay on one of these the other day. Damn site quicker and cheaper than a new module!
The heater is switched in the neutral. Check that there is live supply to the heater. If there is live then the chances are you have a fault on the board. (the heater is energised at the same time as the dispenser opens… always a useful tip).
If you don’t want to change the relay, the boards are not that expensive. Only £15 or so from Connect.
