The washer stopped in the middle of a cycle. No codes were flashed and the control panel would allow selections but no response from the washer. I inititailly checked the continuity in the grey ribbon cable and it checked out OK. I have also checked the continuity in the wiring hrnesses from the door lock switch to the ECU. I have replaced the ECU and the electronic control panel and no change. I am down to either the motor control unit or the door switch. ANy ideas out there?
