Fisher & Paykel Laundry washer
I have a F&P washer top loading Smart drive washer fitted with O51 motor control board. Problem is the Hot water supply to washer is always restricted. I am on high pressure mains (hot and cold) This is what I've done already.
1; checked supply pipes and filters to washer -- all good
2; put new hot valve and solenoid in machine - no change
3; swapped hot valve and solenoid with cold water ones- no change
4; swapped over red wires and green wires (hot>cold) -no change
5; put in new O51 circuit board. still no change
6; put in new plastic 'box' that hot / cold taps sit in. - no change
I found some water flows out hot tap connection from cold side when the hot connection is disconnected, meaning the pressure from cold is passing through hot valve. (all valves I've used)
Could it be that the Cold side pressure is stopping the hot side valve seat from opening thus causing my problem. ?? I will do test and throttle cold side.
thanks for help.
