Keep getting error code f28. Can't get anyone to tell me what it means or how to fix it. If you can help me with this code I would greatly appreciated it thank you
The F28 error code indicates a serial communication error between the Central Control unit (CCU) and Motor Control Unit (MCU). Possible causes and procedure, Unplug washer or disconnect power. Check the wire harness connections to the MCU, the motor, and the CCU. Check connections of the CCU board within the housing. Make sure that all grounding switches are engaged. Check the drive system for any worn or failed components. Plug in the 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 and 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. Look for corrosion on the wires and clean with alcohol where necessary.
