hotpoint sdw60 not working/ no prog select?

my sdw60 dishwasher stopped working, 1st off 2 of the prog led's started flashing(think it was the pre-wash and eco 45) i tilted machine and shook it slightly and reset power it worked as normal ie I could select a programme, i set it going on a programme which started for about 30 secs then stopped. after that none of the led's in the prog select on left hand side of control panel would even light up no matter what I tried.I checked wiring connection to circuit board which all seemed ok any help would be gratefully appreciated....
