I have a Whirlpool ADP262WH Dishwasher (about 4 years old) which gets stuck in its wash cycle. It gets about 1/3 of the way through before sticking and not moving on. If I move the programme dial on a few degrees it carries on and then sticks again. I can do this a couple of times and it will finish the cycle, eventually.
I have replaced the timer (at £69.99) and that was not the cause, it is still faulty.
Would anyone have any idea of something else I can try, your advice would be gratefully received.
