Hi,
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.

Not good! Probably motor control board or motor or wiring harness from control board to motor.

I have a whirlpool duet sport that is displaying F28 code. I have replaced the ccu unit now what do I do. It fills but will not wash, drains but will not spin HELP PLEASE!


For the F28 error code:
First, check the wiring harness connections to the MCU, the Motor, and the CCU. Make sure all the connections are tight and there are no ground wires off. Then check the connections of the CCU board within the housing.

If the wiring connections are fine then It would be a good idea to order both, as both components have been problematic for the error code F28.


Here is the CCU to order.

Here is the MCU to order.

My washer stopped and was flashing F21 (drainage issue) so I called a plumber. He checked the hoses and removed the panel and cleaned the drain trap. It didn't fix the problem it's still won't drain. It...


The SUD message relates to overdose of detergent detected during the Wash Cycle.
This may signify a bad pump, an extra heavy load, excessive detergent or excessive suds.
If too much detergent was used, run the washer through a Rinse/Spin cycle, then a Normal cycle, without adding any detergent. This should clear the unit of the excess detergent.
Check the drain hose and make sure it is not plugged or kinked. this seems to be the reason as to why your unit is not fixed even after trying to solve F21......

F28 is a communication error which usually means there is a connection that has come loose. Removing the top and unpplugging and replugging the connectors in will fix 75% of these codes. If the bottom toe panel is not on it will also give you an F28.
Good luck
