F-28 is a serial communication error. either your main cntrl or motor control is going to be bad. hard to say which one without a multi meter and the machine in front of me though.

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.

I had a short power outage and then my washer gave an error code of F28 and now I can't get it to work. Please help


F28 is a s error from the CCU to the MCUUnit.

remove the lid and the back of the machine.

CCU is the box at the top front right hand corner.
look for connector M13 with a red mark on it and only 3 wires disconnect it and pull gently on the connector.
Spray the contacts of the connector and computer with connector cleaner.
put back together.......

MCU is at back lower left corner.
Find the connector with 3 wires and red mark, pull off this connector , spray it and put it back....should be job done...............

cheers

Code f28


Hi, the error code F28 means one or both of these parts are bad.
  • Motor Control Unit (8540135)
  • Microcomputer Machine Control Unit (8540788)
It would be a good idea to order both, as both components have been problematic for error code F28. If you find either the MCU or the CCU(Microcomputer Machine Control Unit) fixed it.

F28 code on whirlpool duet washer. The door locks


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.
