I removed and cleaned the wire connections on the motor control board as well as bending the connector contacts to insure a good connection to the board. I was considering opening the relays on the main board and cleaning them as well as considering replacement relays as that is the root cause of the door lock failure but I decided to replace the CCU. I could tap in the CCU and see that the washer would cycle thru after cleaning the connections which led me to the conclusion that the relays had become dirty.
