Hi my daughters Beko DW2731FW Dish Washer has stopped completing the wash cycle - it just stays in that part of the wash for ever. If you click the control knob on after a while, it will end but it wont have washed properly. She tried one of the Dish Washer Cleaner bottles and it didn't use all of the bottle ... maybe that is a clue? Same problem on other programmes too, she said it all started to go wrong after it spilled water on the floor one day - but no signs of any leak now. Any ideas please?
