Wits' End With Wf640

[Nestleaver1]

Hello anybody who might be able to help.

A long time ago our Hotpoint Aquarius WF640 did the all lights flashing thing. We took out the PCB, replaced a capacitor and it worked! Hooray. BUT it would not spin at the end of cycle, pumping out but no spin and sticking at one minute (this seems to be a common problem). Switch to spin and it spun fine. Once for a few seconds it flashed f08 - heater relay fault - but never again. It was not heating up or taking hot water so I temporarily switched the pipes. Waste of hot water but we got a hot wash with manual spin cycle.

I have read so much advice and I'm really grateful for all the sensible, clear, logical information given.

I have tested the heater/thermostat with multimeter - both check out OK and thermostat resistance changes with heat. I also checked earth to heater and power to heater as well as thermostat wires to PCB. All intact. But it doesn't take hot feed OR heat up.

I checked the pressure switch was working (it did) - the pipe bubbled when I blew thru it so I checked the pump (again). Found a bra wire but removing this did not help.

I bought a refurb PCB and swapped it out thinking it MUST be that we had damaged it somehow with the original repair ... same problem.

I read that it was usually a broken wire to the motor causing this 1 minute/no spin problem so I have just checked continuity of all the wires from PCB to motor - all fine.

Seems that there is absolutely nothing wrong with this machine except there's something wrong with it!

Any more ideas gratefully received.

Thank you so much! KT
