The error code
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.
You can download the online repair manual in the below link
On page# 4-20 it shows how to access your MCU.

Just tilt the washer back and prop it up with some wood blocks. Three screws are right on the front at the very bottom. Use a 9/32 socket to remove them. The front cover slides right off. The drain trapclean out is right in the middle. Turn the large white knob counter-clockwise to remove it and clean.
Thank you !!

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.
