My whirlpool duet sport washer door will not unlock and I am getting a F--28 error message

Hello, and thank you for using this service. I'll be helping you with your problem today.

F28 means that your main central control board (CCU) and the motor control board (MCU) are not communicating with one another properly. The motor control board is located under the tub mounted to the floor of the washer. The CCU is mounted under the top panel of the washer and is the part with about 100 wires going into it. You'll want to remove the top panel and the lower front panel to check the wire connections and make sure they are all secure. If everything looks good, then you just have to guess which control board you want to replace first, either the MCU or the CCU and the problem is that there is no way to test and determine which part is faulty so it's just a guessing game. That being said, usually the MCU is the faulty part on these Duet Sport models, so I would replace the MCU first.

Now to unlock the door, remove the 3 screws along the bottom of the lower front panel. The panel will then pull straight down and off. Once you remove this panel you can reach up behind the upper front panel and pull down on the small plastic pull tab attached to the bottom of the door lock assembly. This will manually unlock the door so you can open the door.
