Question about Whirlpool GU2400XTP Built-in Dishwasher

1 Answer

Will not start wash cycle

I installed our GU2400XTP dishwasher last week and it worked fine--no problems. For unknown reason, it stopped working yesterday. The electronic touch screen lights up and accepts all cycle commands, however it does not Start the wash cycle. I have tried the "Cancel/Drain" button several times. It cycles for the 2 minute cycle, which should clear all problems, and turns off when the cycle completes. However, it still will not start for new cycles. Our 2-digit display does not show any errors.

Re: Will not start wash cycle

The circuit boards on these types of units are kind of finicky. If there is any seepage of the steam generated by washing that gets into the door skin, then it can toast a circuit in no time flat. It is more than likely the momentary switch but the only way to find out is to remove the inner skin, pull the board, and look for toasted components and check continuity through said switch.

Starts but will not go into wash cycle

My solution to this problem was to simply unplug the power from the wall for a few seconds...plug back in, try to cycle again and the wash cycle starts fine now. May have been caught in a cycle loop or something. Any way this solution worked for me hope it works for someone else.

My dishwasher model adp 941 won't start - start led flashes

exactly the same problem today with an AD9520

Don't know the cause but from reading other posts re dishwasher problems I tried holding start but on for 5 - 10 seconds and it seemed to clear the symptoms at least. It ran for a short while and stopped but the flashing had stopped and I could start a wash cycle which is now running!

blown, or has a circuit breaker tripped?
Has the motor stopped due to an overload? The motor
automatically resets itself within a few minutes. If it does not
restart, call for service.
Is the water shutoff valve (if installed) turned on?
It is normal for certain cycles to repeatedly pause for several
seconds during the main wash.

Error code 2H.....or stops on last minute

I don't think you'll find it's the control board.
I think you'll find it's the heater box.
Not an easy job to do yourself unless of course you know what you are doing.
I would suggest you contact Bosch. One other possiblity is that the water inlet is blocked, although to be honest this is very rare.

GE Nautilus won't drain after Rinse Cycle

Check disposer plug. If a garbage disposer has been recently installed, it is possible the disposer drain plug was not removed. The drain plug is a plastic piece in the disposer that blocks the hole where the dishwasher hose connects. Also check the hose connected to the disposal. Mine apparently had a kink in it. When I straightened the hose the dishwasher drained at full speed (I recently had a plumber re-route a hot waterline. He must has bent the hose). Hope this helps. If not go to the GE website. That's where I found my answer.
