SOURCE: WHIRLPOOL DUET SPORT WASHER FLASH FAULT CODE F28

F28 is a serial bus error from the CCU (Central Control Unit) to the MCU (Motor Control Unit).

All you need is some Electronics contact cleaner spray and a 1/4 inch socket to remove the top of the machine and the back of the machine.
The CCU is the computer looking box at the top front right hand corner.
Find connector M13, (has red marking on it and only 3 wires) disconnect it by pushing the retainer tab back and pulling gently on the connector.
Spray the contacts of the connector and computer with connector cleaner.
Then re-assemble connector.
The MCU is in the back lower left corner.
Find the connector with 3 wires and red mark, and remove this connector in the same way you did the other, spray it and re-install.
Put the back and top back on.

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

Whirlpool f28 error code and door lock light


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 a link to the CCU.

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
