f28 error

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 replace the MCU because it has failed I’m sorry to say. Below is a link to the part for your model.
