I am after some advice regarding my dishwasher. For some reason it doesn’t stop after a chosen cycle. It only stops once it finishes the final setting (nr 5). It heats the water and drains it fine, its just a matter of shutting down.
At a guess and, without doing a bit of detective work to narrow it down, I’d be taking a guess at a thermostat or heater fault causing it. If it doesn’t reach temperature it will just sit there and never move on.
But as you say that it’s heating that kinda kills that idea.
Other than that pressure switch or controller really.
