We have a Fisher & Paykel GWL10, the problem

Hi,

Check the water inlet valve. Unplug the machine and turn off the water. Remove the water supply hoses and check the small metal screens inside the openings on the valve. Make sure they are clear of rust or debris. Check the solenoids using a multimeter or ohmmeter. Check for continuity. A lack of continuity means a bad solenoid.

Thanks

ok
I will admit, one of the most dertailed explanations here, I have been reapiring these units and I have never come across this, particular problem.
Although I will tell you this, the problem is in your programming,
or your cold water valve is clogged,, the fill and drain thing is temp control issue,,, it is actualy calibrating the tank water temp, for the required normal wash temp.
Unplug the machine,
Turn off your water, and disconnect, your hoses, hang a towel over the control panal, any water here is dangerous...
inspect your water valve screens, cold inparticular..
then open the control panel..... from the top and remove your control cover,,,,,,its important to unplug this first for feedback issues
on the left you will see your water valve, unplug the solonoids,, ohm these out, you should have continuity through the coils on both valves, they must be unpluged to isolte the coil.
if both of these are good. ITs your control board, or programming issue.
More often then not its a burn resistor on the board some where in the water circuit..... I wont pretend to be an engineer, I never understood why you need such a circuit to open a valve, but hey..... im just a blue collar guy.
Parts are not hard to find, and the reapair can easily be done by you
they are available at www.searspartsdirect.com
the part number is 426930P......
please be advised this part is $200.00,,,,, and without actually taking the voltages myself, i could no way guarentee this is correct.
these machines have a way of making anyone look foolish.
but if you can understand my driblle here, it should get you on the right traqck

It is possible that the water flow to the unit is low and the timer is advancing before the drum is full

Check the inlet valve for blockages, to do so you have to start the machine as if you are doing a wash but turn the water supply off.

This will release the pressure in the supply lines

Undo the connector on the back and look inside the valve entrance for dirt or grit in the filter , if it is dirty you can pull it out using a paipr of fine nosed pliers.

Re-assemble and test

After that you are looking at obstructions in the pressure switch line or the pressure switch itself

I have reviewed your problem and have the fallowing items for you to access.
First, this sound like your timer has taken a turn for the worst.
If the unit will complete a cycle, once started manually, the timer is the part you will need to look at.
Below I am leaving you a parts look up website for your unit but can only go so fare with present information.
Hope this works for you, a timer is allot cheaper than a motor or transmission part.
Good luck, hope this works for you.
Please rate....
