I am getting the same problem w/ the door locked. The cancel light stays on and it doesn't start the diagnostic cycle. I can get it to show the error codes, but after that it locks the door to start diagnostic cycle and then doesn't start. The rinse drain light will light up after that and keep blinking. Also has the add a garment light on.
I replaced the control board p# W10246289
and the door latch p# W10253483
. It still doesn't work.... What should I do? Replace the control panel board?
