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 lef t when facing
the MCU connectors.

What is the model number of your washer?

My washer keeps flashing and saying FH or Hf ... what does this mean?


Check to make sure you are getting a good supply of water to the washer. Remove hoses at the washer and make sure the filter screens are not clogged.

F-28 flashing. Door will not open


While the machine is on press "end of cycle" for 3 seconds, then wait for 2 minutes to try the door. Try this again if it does not open, this is the child lock program - to lock and unlock; it is the same procedure.

Check your washer plug to see if the connections are tightly screwed. You can also plug off for half an hour to reset.
