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.

I have an F28 error what is wrong


As far as I know F28 error code means - SERIAL COMMUNICATIONS ERROR/MOTOR CONTROL UNIT ERROR. Caused by either a communications problem between the Central Control Unit and Motor Control Unit, or Motor Control Unit internal failure.

It starts and then stops and then F28 flashes

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.
Here is a link to the MCU.

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.

It gives a F28 code. What is that?


F28 is a motor controller error... Try unplugging the machine for a minute or two, then starting it again. If no good, you can remove the access cover and check the connections to the motor... BE SURE TO UNPLUG FROM WALL FIRST...
