F11 ERROR CODE

Here is the tech sheet on your unit. Now you can run the test cycle and see what happens. Its hard to say which one is bad. If you do not get any motor movement I would start with the MCU.

HI. The F11 error code on your unit means a communication error between the CCU and MCU. I have seen this many times before. There is not any way to determine which control board is faulty. It can be either the CCU or MCU or a loose or broken wire between them. 8182695 is the CU and W10756692 is the MCU. Here is what the tech sheet says about the error code.

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.

I have attached 2 videos for the MCU and CCU. Not the same unit or parts as yours but it will be the same procedure.
