I’ve only had chance to have a quick look at this one,door won’t open until you unplug the m/c,tried new interlock (i knew it wasn’t gonna be that but hey) & when you switch it on & close the door it locks even tho’ you haven’t selected a prog! Also customer says sometimes (always sometimes) the on/off neon along with wash neon flash plus energy save & time saver flash aswell ,but what do you know it didn’t when i was there ! So any clues please guys,I checked the usual heater ‘pump etc apart from the door interlock prob it seems to wash ok.She says she can put up with the door fault cos she just switches it of at the socket but its the flashing neons the bug me. The word EPROM keeps popping up in my confused mind :rolls:
Regards Chris…Re: Hotpoint WF000
Almost certainly a short circuit triac on the board (the one that supplies the interlock). If you trace the interlock wires to the PCB and follow the tracks you will find the culprit. Probably surface mounted so not easy to change without a hot air iron. A lot of these triacs are similar so you might get away with one off another scrap board.
If that does not work then the tiny transistor that drives the triac might be blown too. I wear three pairs of reading glasses on top of each other when doing surface mounted – very effective.
If you manage to repair it change the interlock too as it has probably caused the damage.
