Our dishwasher began to stop probably randomly at various points in the cycle. I have had a technician out to it. First attempt he thought it was a loose connection, waggled a few plugs and went away. Same problem. Second attempt he replaced the £70 heater element. Same problem. My tests show the original element was OK anyway. The guy is obviously groping in the dark and I don't want to waste time and money calling him out again.
The machine won't go past the first pump out now.
There appears to be a loose contact or intermittent fault in a sensor somewhere.
I am an industrial electrician and fix much more complex machines than this, but without any documentation about what the machine cycle should be (e.g. what signal it is waiting for next) and a wiring diagram, it is difficult to logically trace where the fault is.
Do you know where I can find any useful info?

The wiring diagram is usually found in the kick plate under the door.

Not in this case I am afraid. Can't find anything on the internet either at present. Will keep looking.
