Looking for a water fill sensor for a fisher paykel gw11 The machine starts the cycle just fine, but when starts to fill, the water just trickles out and both water lines are open, whats wrong?

Hi from retired Englishman in SW France,
(sorry if this does not fully answer your question!)

If you have checked that the hot and cold water taps are turned on fully and the hoses are not kinked or squashed at the back, it is worth while checking both the hot and cold water inlet filters. Turn the taps off and remove both hoses at the washer end. Inside each inlet port there is normally a little filter which should just slide out. Clean if necessary and replace each one and the hoses. If after turning the taps back on there is no improvement, the problem is symptomatic of a malfunctioning hot or cold water control valve. Sorry but it needs a service call and a check that it isn't the control PCB ;-0(

If this has assisted you please consider a 4 thumbs up for the rating.
Thanks and good luck,
John C
