F28 ERROR means SERIAL COMMUNICATION ERROR
The communication between the Central Control Unit (CCU) and the Motor Control Unit (MCU) cannot be sent correctly.

what to do:

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 the housing.
Make sure all grounding switches are engaged.
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.
9. Check doorswitch system. (See checklist of F26 and F29). The doorswitch may cause an interference for the powersupply of the
MCU.
