F 11 error keeps coming up, I can hear a switch in the back of the unit clicking. I'll tap the back of the machine and the unit starts back up and clears the alarm. It's starting to occur more often now...
HI. This is a wiring harness issue.
Communication between the Central Control Unit (CCU) and the Motor Control Unit (MCU) cannot be sent correctly.
Possible Causes / Procedure
1. Unplug washer or disconnect power.
2. Check wire harness connections to the MCU, the motor, and Central Control Unit (CCU).
3. Check the drive system for any worn or failed components.
4. Plug in washer or reconnect power.
5. Verify CCU operation by running a Diagnostic test or any cycle.
6. Check the MCU by looking for operations of the drive motor.
7. Check the drive motor for powered rotations.
8. Check that the serial harness at the MCU is not mounted upside down. The wires should be to the left when facing the MCU connectors.
Replace failed component.( the likely culprit will be a failed harness if the MCU is operational, but if the harness is connected properly, and with no corroded or loose contacts, replace the MCU)
