Have you tried switching the power off at the wall for 5 minutes, turning it back on, and then selecting a basic \ rinse programme, and seeing if the dishwasher starts?
So you able to chose \ change the program, but it doesnt start.
If left for 5 minutes set on a program does it beep\flights flash?
If your content the door lock\switch is working, then it would suggest the PCB has failed as its not detecting the required input to commence the program.
Unfortunately the PCB is obsolete, I have checked the big 5 spares vendors and none of them are listing it as available, so it looks that the machine is beyond economical repair.
However I would be inclined to take one more look at the door lock, and checking it with a multi meter, as 70% of these issues are during faulty door lock, as these parts are still available.
