Question about Whirlpool Duet GHW9150P Front Load Washer
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.

The Code 28 error is one of several Device Manager error codes. The Code 28 error will almost always display exactly like this:
"The drivers for this device are not installed. (Code 28)"
Details on Device Manager error codes like Code 28 are available in the Device Status area in the device's properties: How to View a Device's Status in Device Manager.
