Re: Fisher&Paykel MW059 washing machine won’t fill

The hot water solenoid bench tested ok on a 24 volt power supply so I started testing components on the Motor/Controller board and soon discovered an open circuit 5.1 ohm resistor. This is in series with the surface mount FET transistors that drive the solenoid valves. When I replaced this resistor the machine burst back into life.
Success!
All this stuff would be so much easier if F&P would allow easy access to service manuals for their machines.

Re: Fisher&Paykel MW059 washing machine won’t fill

I replaced the cold inlet valve (old one had high resistance ~600 ohms) but still have same problem except that Progress leds now show
00110010.
I can measure high volts on the Motor Controller board (>300v) and both the pcb mounted fuses are ok. Lid switch and Out of Balance switch are ok.
Any more advice?

Cheers kiwipete
