I have a hotpoint Aquarius dishwasher 6 years old it empties ok but the pump doesn't stop running, so it wont re-fill. I ended the cycle and restarted it, the pump starts straight away as normal but it doesn't stop and does not take on fresh water but goes thru the cycle, minutes counting down but the pump NEVER STOPS pumping even though there is no water to pump out.Water supply on. Filters cleaned.
