Hotpoint WD63P Washer/Drier

[DentedPorsche]

Hiyas, Got one of these on the go with a heating problem.
Customer complaining that it won’t do a boil wash.
Heater and thermistor have been replaced as has the timer.
Any one got any ideas or suggestions ??
Thanks.

Hi DP,

Maybe wiring fault between thermistor and timer? or an exotic fault with the economy switch?
sounds like the kind of job i get monday mornings!

Hey DP, elaborate a bit. What doesnt it do exactly. Just not get hot enough or not at all or not even fill in the first place?
Do these still have a 90 degree safety stat on them? (thinking about it I dont think they do) if so it could be that.

These machines just don’t do boil washes. All the thermister does is delay the progress of the timer – it does not ‘hold’ the timer until it boils. If the water goes into the drum cool or just warm, then it will not get any where near boiling. Earlier Hotpoint timers (9545 etc) had solenoids to hold the timer (wash action continued though) or more basic versions just stopped the timer until the temperature reached a pre-set level (using ordinary on/off stats). It really is surprising given the complexity of the timers in say this WD63P (904/2426/02 timer) including the use of a 28 pin microcontroller, that Hotpoint did not make the heating circuits more intelligent. That is why, on these machines, an open circuit heater will not stop the timer moving on. Still, that’s progress for you. To make matters worse, a common fault with these timers is the tendance to ‘double advance’ where the timer speeds its way through a wash. 95{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} of the timers we receive back as exchange units have this problem so beware that ‘good timer’ that you have in a box in your garage – it’s highly likely that it will have this problem (affects 904/2409 series, 904/2411 series, 904/2412 series, 904/2425 series, 904/2426 series & 904/2440 series ). Needless to say we take action to permanently stop this on our reconditioned timers giving them a longer life than new ones.

Thanks for that Tony, you’ve just explained the problems I’ve been trying to cure. I’ll just print out your reply and send it to the boss man at work, put the ball back in his court.
