Re: Whirlpool DU1050 will not start
There may be a thermal fuse located on the electronic control board housing that may have failed.This replaceable part (gray or white) is clipped on to the side of the housing. Unplug DW and remove console to gain access.

My name is Peter. I am a retired field service appliance technician.
Transporting the dishwasher on its back should not have been a problem. It is only with refrigerators and freezers that need to be transported up right, to prevent compressor oil getting into the refrigerant sealed system.
You may have a power cord problem. You have a 3 or 4 wire power cord. If you have a 3 wire power cord you need a 15 amp circuit breaker. If you have a 4 wired power cord you need a 30 amp circuit breaker.
The wall socket that you are plugged into my not have a ground.
You need to check the wall socket and the wire connects at the dishwasher. Send me a model number so I can see what you have. If you have a 4 wire connection you can chance the cord to a 3 wire. On a three wire you have a neutral and two hot with a small green ground wire. On a 4 wire you have a neutral two hot wires and a neutral in the center with a ground wire.
I would put my money on the wall socket not having a ground.
To eliminate a dishwasher problem, run a heavy 3 pronged extension cord from a known working outlet to the dishwasher and plug the dishwasher into the cord. If you still have no power (dishwasher is not showing any signs of life) then it is a dishwasher problem (circuit board, bad connection from dishwasher cord to dishwasher, etc).
If the dishwasher actually shows signs of life, then you may have a tripped breaker. Check the breaker to make sure it is on and that the tab is not either in the center or the off position. Also, try moving the dishwasher cord's plug from the outlet it is currently in to another outlet in the under sink area. There is a chance that the plug got switched from the normal outlet to the outlet that controls the garbage disposal, that outlet should only be hot when the disposal wall switch is flipped to the on position.
Flashing PF = power failure. The power source and connections need to be inspected for bening loose or hot. This would be at the wall connection and in the bottom of the dishwasher. If the supply power source is good all the way to the dishwaher and to the dishwasher control.. suspect corrosion in the control area as the source of the problem. When corrosion gets on an electronic board it starts acting like a conductor for the low voltages produced by the PDB transformer which starts causing all kinds of weird symptoms. If the PCB can be cleaned carefully you can maybe get 6 months to a year out of a PCB that has / had corrosion problems. My 40 years experience is that only one in 5 can be salvaged back into service. Additionally those that are placed bacm in service eventually have other problems.
If you have a loose plug, wires, outlet or power cord... your in luck.
Thanks for choosing FixYa,
Thanks for using FixYa. If the clean light flashes, pauses, and then repeats. When the dishwasher doesn't sense a water temperature increase, it stops working and locks the functions (clean light flashes, all buttons are non responsive). It does this as a safety in case the element is broken and feeding electrical current into the water.
To resolve this you will have to reset the console. Do this by closing the door and press these buttons in sequence... -high temp wash -heated dry -high temp wash -heated dry
Please do rate the solution if the issue is resolved or post a comment for further assistance.
Did you check power to the unit? Double check the common and grounds. When servicing I will disconect(unplug from wall) power to the unit. Is it pluged in? Use another outlet(the outlet under the sink may be wired thru a switch for a disposer)even if you need an extension cord. Hope this helps.
Make sure you have power to the dishwasher, check circuit breaker. If circuit breaker is ok, then remove toe panel at bottom front of machine, on the right hand side is where the power cable goes into a little metal box. Turn off circuit breaker to kill power to the dishwasher, remove electrical box cover and check to make sure that the wire nuts are tight. Reapply power and test. If still no go then remove tech service sheet from toe panel insulation, get yourself a multi-meter and start test individual components until you find the one that is bad. Hope this helps.
