GE Dishwasher cuts off mid-cycle

Brand: GE
Model Number: GDF535PGR5WW
Main Symptom: Cuts off
What happens & when:

I have a GE dishwasher GDF535PGR5WW that quits mid-cycle. All lights go off and the cycle has to be restarted by pressing the start button twice. Then, the lights come back on. The door is secure and pushing it in does not help. Can you help me determine which part I need?

If you press cycle while the door is closed, then press and hold the cycle and start buttons at the same time for five seconds (the door status will be identified with all of the LEDs being on or off for 10 seconds), does the LED above the start button flash?

All the lights come on briefly and then go off. Only the clean button remains on after that.

As there is not an error code appearing, this is going to be a control issue. The most likely failure would be the main control. WD21X32938 Configured Machine Control Board | Genuine Ge OEM In Stock

Actually, it was a gummed-up pressure sensor. I put in a new one and the cycle completed.
