Question about Whirlpool Duet GHW9150P Front Load Washer
The F-28 code is a communication error between the Central Control Unit (CCU) and the Motor Control Unit (MCU).
1.Unplug the washer
2.Check the wire harness connections to the MCU, the motor, and the CCU
Check connections of the CCU board within the housing.
Make sure all grounding switches are engaged.
1.Check the drive system for any worn or failed components.
2.Plug in washer or reconnect power.
3.Verify CCU operation by running a Diagnostic Test or any cycle.
4.Check the MCU by looking for operations of the drive motor.
5.Check the drive motor for powered rotations.
6.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.
Hope this helps.
