Kenmore HE2 110.46462501 Cannot resolve F28 Error

4 posts in this topic

I am completely stumped by this washer. When I start a cycle the washer locks the door and then just sits there until it times out and I get the F28 (Rinse,Spin,Clothes Clean lights) error. I replaced the MMU with no change and then the CCU with no change. I also checked the continuity of the safety switches in the front and rear to ensure they were working. Still does the same thing. Any ideas???

SERIAL COMMUNICATION ERROR

The 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).

– 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.
