I have a diplomat ADP 8234 integrated dishwasher. When I choose cycle and close door I get a double (treble?) beep and there is 'WHOOSH' like it's trying to start a cycle and then it stops abruptly... and it's keeps cycling through this double-beep/whoosh sequence. No obvious error codes, although the LCD threw a wee wobbly just before this behaviour started, although it corrected itself. Any ideas?
