Hotpoint WD71P – Another One

Oh, I love these – not. So this particular little beastie occasionally throws up an E31 on wash, and E18 on dry. E18, they cry? I know, I can’t find it either…….. Anyway the customer seems to be able to cope with these occasional vagaries of logic (are they all mad, or do I just get them?) – what it is doing at the end of the drying cycle is that the power board buzzes quietly, then a valve pulses, the blower motor kicks and the motor relay clicks on the power board. Only for a second or two at a time, but it continues to do it ad infinitum. It only does this at the end of the drying cycle – the programme is finished. So, got to be to do with the dryer, hasn’t it? 4meg to earth on the rear heater element, nothing on the front one. Disconnect completely rear element, run on full heat, does exactly the same. Hmm…. Check all wiring for chafing etc – I’m stumped.

Ideas?

S/no is 62164686 if it helps anyone.

Thanks,
