I have a Diplomat ADP 8242 dishwasher purchased January 2003. It fails to start fairly regularly – the program light flashes ( the program we leave it on ECO ) but the selector function is frozen and if you switch off and switch on again and press the main slector button you just get 2 beeps and nothing else. When it has happened before I have switched it off and left it overnight and teh fault clears. I had someone to look at it – he wasn’t sure but said the circuit board is rubbish and said it needs a new one at £150.
