this is the code meaning,



The communication between the Central Control Unit (CCU) and the

Motor Control Unit (MCU) cannot be sent correctly.

Possible Causes/Procedure

Unplug washer or disconnect power.

Check wire harness connections to the MCU, the motor, and Central

Control Unit (CCU).

Check connections of the CCU board within the housing.

Make sure all grounding switches are engaged.

Check the drive system for any worn or failed components.

Plug in washer or reconnect power.

Verify CCU operation by running a Diagnostic Test or any cycle.

Check the MCU by looking for operations of the drive motor.

Check the drive motor for powered rotations.

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. there is usually a service diagnostic tech sheet in the bottom front of the cabinet behind the panel under the door, if you can find it click this link,
