Question about Dishwashers

1 Answer

I have a Fisher & Paykel 913T soft touch dishwasher. On all types of washes when the wash cycle starts there is no 230 volts on the element & after 5 minutes the wash cycle finishes & then goes onto to the next cycle. None of the wash or rinse cycles heat the water but on the dry cycle their is 230 volts onto the element & dries the dishes OK. Is my problem the power supply PCB or could it be the Controller PCB? Does the 230 volts to the element on dry cycle come from the same cicuit on the power supply PCB as the wash cycle or from a different circuit? Regards Ian

    Thanks for your help. The temperature sensor seems to be a separate part from the element so I will try a new one of these.

    Hi Guru,

    I tried another temp sensor but still had the same problem. I removed the power supply & checked all connections & resoldered all the PCB & the problem seems OK . I will await further testing.



    Thanks for your help.

    Yes that is correct. Resoldering the power supply seems to have fixed the problem . Thanks again.

Have you considered the possibility the water temperature sensor may be faulty.

If the controller is getting false water temp reading then it may never turn the heater on.

Generally with FP dishwashers, the heating element and temperature sensor are part of the same assembly, so you you have to replace both. I don't have access to the 913T service manual but I am saying this on the basis of my experience with the other dishwashers from FP.

Hope this helps.

    Thanks for the update.

    Looks like you have fixed the problem by resoldering power supply points. Is that correct?

How do I replace handle/plastic cover on Fisher and Paykel soft touch 913t dishwasher?


Not sure if you have tried to refer to the parts manual itself which shows how the parts are assembled together. In particular page 8 which shows the handle assembly part 18. I am assuming this is what you are replacing. Or is it just part 21 which is the plastic latch recess cover.

Most likely a fault with the heater element. Check if the water is warm when it stops during a heavy wash cycle.

913T Dishwasher Stops after 10 seconds


913T is a very old model (1996), I have one, I'm not a repairer, I have the same fault. It doesn't have drawers or infrared or a display.
I've just shortened the ribbon cable, which had pinch damage at the door close pinch point. I used a male & female ribbon squeeze connector pair to make a good clean joint. With the cable fault it wasn't even starting the drain cycle. Now it does start, but then long beeps, and I suspect it's detecting a fault with the motor or a sensor or faulty wire, and is halting.
I've found running the rinse cycle first then allows the main wash cycle to run, no longer stopping at 10 seconds (after the initial drain), just as the first power wash commences.

My Fisher and Paykel dishdrawer has worked fine up until a week ago when it started being temperamental. It stops during the wash cycle anything up to 5 times claiming that it has no water. I push start...


I don't know if this will help. I had to work on Fisher & Paykel two draw dishwasher. The one problem was one draw would work but the other wouldn't. There is one board for each draw and one board in the base. The board in the base seem to be the power supply for the rest of the machine. I don't remember the model number and it has been years ago. Getting to the boards was not easy.
I did the swap the two draw boards and the problem didn't move. So whatever the problem was it was in the draw. I found Fisher & Paykel had design the heating element as a resistor to drop the 110 VAC down to a voltage the logic/controller board can use turn to Dc voltage to run board. The problem I found was the heating element had opened. There was no power to run the board. Later there was also a cable problem the confounded the repairman. He had to replace the draw harness.
My really big problem is the heating was on the ground side of the logic/controller board. The logic/controller board was on the 110 VAC side. So that if the heating element opened the logic/controller board would be floating up to 110 VAC. So any meter measurement on the board show 110 VAC. Even touching any part of the board and any part of washer you can get zapped. So be careful. It should the other way around so the board is at the ground side and heating element on the high side. If the heat element opened there would be no power to the board would be at ground level and no shock problem.

Fisher & Paykel leaves film


When a film is left on the dishes, the problem is almost always a failed heating element. Dishwasher detergent requires a high temp to fully disolve and be effective as a a cleaner (solvent.) When the element does not come on during the wash cycle, the detergent is never activated.

It is ~possible~ that the thermister has failed, but some sort of error code should be reported if that was the cause.

Good Luck! Please report back what you find. OK?
