When going to wash with my GW11 it stops during the was cycle and the cold and hot water light blink and the machine beeps

Pump is most likely bad if it’s unibstructed but very hot. I’d replace it.

Water Valve Test
When in Diagnostic Mode, the WASH TEMP UP button turns the hot water valve on. The Hot LED is on when the hot valve is on. The WASH TEMP DOWN button turns the cold water valve on. The Cold LED is on when the cold valve is on.

DIAGNOSTIC MODE
Turn the power on at the power point but off at the machine. Press and hold the WASH TEMP DOWN button and then the POWER button until the machine gives 2 short beeps and lights up. Release buttons when the beeps indicate diagnostic mode has been entered.

There maybe up to 3 filters cold water line. There is sometimes 1 at each end of the water hose itself and also in the valve which can be removed with pliers. (see picture)

Undo the 2 screws at the back of the buttons panel
Undo the connection of the valve
If you are good with a multimeter check that there is about 65 ohms resistance across the terminals of the valve. If not, then replace the valve.
Also sometimes the workings inside the valve can jam shut so replace the valve.

Is it model GWL11? There is no model GW11. On most other models that code indicates there is a fault in the water pressure transducer which measures the water level. Unfortunately the motor controller module needs to be replaced.

Hello there and thank you for choosing fixya
this is a very common issue with these machines
what the problem is most of the time is that the water inlet valve that the hoses connect to has done 1 of 3 things
this valve will clog up with deposits and need to be cleaned out so check that first see if you can see inside of it and check the screen on the hose itself to ensure that it is clean.
If it is then ensure that you do indeed have adequate water pressure coming out of both of the hoses and make sure they are straight if so than the only thing that can be wrong is the water inlet valve itself
This is because this valve has a solenoid for the hot and one solenoid for the cold and when the valve starts to fail the valve will partially shut thus resulting in the water not getting in the machine very quickly ok
If you feel like you can do the repairs if needed please post me a comment and i can get you the proper repair procedures for this machine i will need the make and model number ok?
Hope all of this has helped
Best regards Mike

I would have thought it was the board too! does it beep when it stops? if it does then it should be putting up a fault code.top row of lights..CHeck that you have both the hot & cold hoses connected & turned on at the taps.even if you are not useing hot water to wash with,turn them both on anyway.Some machines require this regardless of wether you are useing hot.The reason for this is F&P have built into their machines to give a little squirt of hot water to maintain a certain level of cold wash.Make sure also that hot hose is going to hot valve & cold to cold.

pressure switch

Need a model # to get exact part you will need at rinse most washer go straight cold so I would say water inlet valve if humming sound is present

WHEN I CALLED FISHER AND PAYKEL PARTS CENTER WITH THE SAME PROBLEM . THIS IS THE REPY I RECEIVED. "THE HOT WATER FILLS IN FOR A SHORT TIME, THEN THE DIRVERTER RECIRCULATES FOR A FEW MORE MINUTES, THEN FILLS THE REMAINING WATER LEVEL YOU HAVE SELECTED WITH COLD WATER. THE REASON BEING: (GET THIS) FISHER PAYKEL SAYS THAT THE AMOUNT OF HOT WATER AT THE BEGINING OF THE
CYCLE IS SUFFICIENT TO DISOLVE THE DETERGENT. AFTER THE DEVERTER CYCLE (THE SIDE RINSE AS YOU CALLED IT) THE REMAINING WILL BE COLD WATER FILL".
HE ALSO STATED MANY PEOPLE CALL HIM ON THIS AND HE SAID IN THE MANUAL IT IS EXPLAINED THAT THIS IS THE WAY THE MACHINE WORKS. SO MUCH FOR ECOSMART

what light is flashing when it beeps. You might have to check and see if you are getting water to both Hot and Cold on the machine. Or your door might be closed all the way

more than likely that your inlet valve is faulty it needs replacing thats the more common fault for water not going into the machine
