F11 error code. Last week, the washer leaked water and we identified a hole in bellow to be the cause of it. I replaced the bellow and tried to ran a cycle and it started to give me F11 error code. I ran a diagnostic test which points to either MCU or motor to be the problem since the washer did not go into the spin cycle. Do you think by replacing the MCU, the problem will be corrected? Thanks
Answer Hello Nick,
F11 is a MOTOR CONTROL UNIT ERROR as per the tech sheet. The Motor Control Unit has internal failure, repeating under or over voltage, or over current conditions. Can also be caused by a momentary loss of neutral feed to the MCU during the spin cycle. If failure occurs during high-speed spin, the door unlocks after 3 minutes. Possible Causes/Procedure 1. Unplug washer or disconnect power. 2. Check wire harness connections between the drive motor and the Motor Control Unit (MCU), and between the MCU and the Central Control Unit (CCU). Check the motor and do a continuity test. 3. Plug in washer or reconnect power. 4. Run a Diagnostic Test and run the motor. If it does
not run, replace the MCU board.

Answer Hello Mike. The communication between the Central Control Unit (CCU)
and theMotor 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).
– Check connections of the CCU board within
– Make sure all grounding switches are engaged.
3. 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.
4. Check the drive system for any worn or failed
5. Plug in washer or reconnect power.
6. Verify CCU operation by running a Diagnostic
Test or any cycle.
7. Check door switch system. The door switch may cause interference
for the power supply of the MCU.
