F28 = SERIAL COMMUNICATION ERROR
The communication between the Central Control Unit (CCU) and the Motor Control Unit (MCU) cannot be sent correctly.
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.

Error code F28 indicates that one of the below part is bad
If you find either the MCU or the CCU(Microcomputer Machine Control Unit) you can fix it,
Here's the online repair manual for Whirlpool Duet Sport, but its identical to your HE2.
Refer page# 4-20 it describes how to get to MCU.

Check your washer plug to see if the connections are
screwed. Next check your filter if you haven't for long.
Remove the 3 screws at the bottom of the front panel under the washer door. Your filter door will be light brown. If you find a hose there it is to drain out excess water (water that could not be drained by your pump) After you hv drained unscrew the cap and remove all the junk inside. Have a large plastic bag to catch junk and water. Refit carefully after cleaning out. If not solved, something shd be blocking your pump, check this out
How abt a nice rating for the free help? Thnks
