Kitchenaid dishwasher KDFE104HPS1, wash pump surges

[MemphisMike]

Model Number

KDFE104HPS1

Brand

KitchenAid

Age

1-5 years

We have a Kitchenaid dishwasher just over a year old. It will fill and drain and run the entire cycle. The diag codes are 43 and 64. The wash pump will come on and then shut down. The voltage at the pump is line voltage 120, but drops to about 70 volts and the pump motor stops.

I have replaced the pump motor and control board with OEM parts. The performance of the dishwasher has not changed. I am getting close to thinking about just replacing the dishwasher. Any help would be greatly appreciated.

Where did you buy the wash motor assembly at Mike? It does make a difference.

Here is the wash motor assembly for your model: W11084656 Motor-Pump

My KitchenAid KDFE104DSS5 dishwasher was filling up with water but not running, so I ran the diagnostic on it and got the 4-3 motor code, and only that one. Before replacing the motor, I followed the advice in this YouTube video and popped open the door and gained access to the controller...
