When running the dishwasher, it will begin to drain, then water will start to fill, but then it never goes to the wash cycle. So I checked around and found a way to do a diagnostic. Running the diagnostic I got 4 blinks pause then 3 blinks indicating Communication stopped from the wash pump motor and the electronic control board. So I decided I was going to do a diagnostic check on the control board to see if it was functioning properly. I had difficulty getting a reading while the pump was plugged into the board (thanks to the crappy multimeter/probes!!) so I unplugged it cause I figured it would output power as it goes through its cycle. Take a look at this quick video I took (https://youtu.be/0fGxtSSYLLc ). Even before the wash cycle, the board is outputting ~50VAC but right when it gets to the wash cycle the output spikes to 110VAC and then goes back to ~50VAC. This doesn’t seem right, I thought it should be 120VAC? Is that correct? I powered everything down and then checked the resistance of the motor and got 22ohms. Is that too low, or does that seem correct? I am thinking that the control board is the faulty part here, does anyone think otherwise? The control board p/n is W10904714
I had the same problem, the cycle just restarts, the pump/motor that does the pumping for the wash needed replacement. The motor seemed to be in good shape but it was inside the pump that had worn out.
