Check the brown wires on the front that go the bottom of the door , inspect the thin bar that covers the loom at the bottom poss broken , give them a little tug.
What was the conclusion of this? I have the same problem, there is power going to the switch but when I press the black nub down for 15 or so seconds nothing happens. Any assitance would be fantastic.
Is the door switch / mechanism actually working? Need to prove this first.
As your aware you will have lights etc and be able to change the wash cycle on the top panel with the door open or closed. That is of course providing the on/off button is in the on position as it is showing in your photo due to the cycle light lit up.
As per 'rocks', check the wiring but just looks like melted black gunge from the door panel due to heat, but is clearly a sign of heat issues so internal wiring could be compromised even if the insulation appears good. Wires can become brittle and break, excess heat from door due to hot water and the opening/closing of the door.
After checking door switch, my advice would be to check continuity of each wire, end to end, rather than breaking into the wires at the door.
I may not get reply anymore under this old thread but I will try anyway before I will open another one. So I have exactly the same issue here with the very same model of dishwasher. I can switch between the programs but it doesn't star when I've close the door. I've opened the front and checked all the wires and lock. To the point I even took the micro switch off and just closed the circuit by connecting the brown wires together. When I use screwdriver type probe, it lights up so the circuit must be ok but it still does nothing.
Any other ideas ???
