the dishwasher when started becomes stuck in cycle, the machine appears to be repeating a part of the programme and intermittently injects water, stops, injects water, stops until you re-adjust the top shelf. I have tried taking to shelves out but the unit now keeps repeating the same fault, I am unable to take the unit through a full programme or interupt the cycle it is presently stuck on?
