Turn off the power. Remove the detergent tray. Reach in the slot where the detergent tray fits and look for a lever. Pull it and replace the detergent tray. Turn power on. Good luck.

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.

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.
