From Tech Sheet W15388175, p.27:

1.Check connections to Wash Process Sensor from control board. Check for bad conductivity sensor. Check control board.

2.Measure control board supply voltage at the test points. Expected: 12 VDC and 5 VDC; a drop below 4.75 VDC on the logic rail points to a failed onboard regulator.

3.Inspect all connectors on the main control for corrosion, thermal stress, or backed-out pins. Reseat each connector with the power disconnected.
