My washer will not start when I set the cycle and shut the door. The panel says " It appears the door was not opened since the last cycle" "If you woul like to start a cycle 1st open & shut the door then press the start pause button". When I do this I get the same maessage again.
I think your choices here are the door lock assembly or the control unit or the wiring between the control unit and the door lock assembly.
There are some good diagnostics on this machine, and use this service manual to try to get them to operate. Despite the cover and material inside, your model is discussed at the very back.
