New Whirlpool Duet Washer(WFW9300VU02) F28 error

I am a contractor who has installed a new Whirlpool duet for a customer. When trying to run a test cycle, water will fill drum for about 5 seconds, then stop when a F28 error appears in display. This happens on all load selections (delicate, normal, heavy etc) I have tried it with clothes in washer and empty. Same result.. Any ideas?

You can call whirlpool for service but the tech sheet f28 has a communication problem from you computer to the motor..

The communication between the Central Control Unit (CCU) and
the Motor Control Unit (MCU) cannot be sent correctly.

Possible Causes/Procedure
1. Unplug washer or disconnect power.
2. Check wire harness connections to the MCU, the motor, and
Central Control Unit (CCU).
Check connections of the CCU board within the housing.
Make sure all grounding switches are engaged.
3. Check the drive system for any worn or failed components.
4. Plug in washer or reconnect power.
5. Verify CCU operation by running a Diagnostic Test or any
cycle.
6. Check the MCU by looking for operations of the drive motor.
7. Check the drive motor for powered rotations.
8. Check that the serial harness at the MCU is not mounted
upside down. The wires should be to the left when facing
the MCU connectors.

Not good! Probably motor control board or motor or wiring harness from control board to motor.

This leads to a Kenmore Video
Whirlpool, Maytag, Kenmore. Same machine different name different trim.

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.

I washed a large load in our Whirlpood Duet Washing Machine and it stopped with a flashing F28 code. I unplugged it for 5 minutes and it still will not run a cycle without stopping with a flashing F28...


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.

You can download the online repair manual in the below link

On page# 4-20 it shows how to access your MCU.
