Hi. I have a whirlpool duet tumblefresh 4.4. When starting it, it just lights the 'add garment' led & does nothing else. No water, no spin. Keeps the door locked too. Had to manually unlock it.

This symptom characterizes a problem with a faulty motor control unit (MCU). It has been found that a fault in the MCU can lead to erratic operation of the machine with or without error codes being flashed. It can be verified by isolating the MCU, that is disconnecting it from the central control unit (CCU). If the machine seems to work fine with the MCU disconnected except motor powered functions, the MCU is indeed the problem and the only viable solution is replacing it.
Unplug the machine or disconnect power then remove the three screws from the rear of the machine top cover. Pull back on the cover and release the tabs in the console from the slots in the cover then lift the cover off the unit.
Locate the CCU then disconnect the MCU harnesses marked MS2 and MI3.
Reconnect power then start the machine. Replace the MCU if the machine seems to work fine except motor powered functions. Otherwise, let us know for further advice.
