I have a Hotpoint FDW20 dishwasher and it has not been emptying fully and the green pre wash light and green wash light stays on when cycle finishes. I have checked that there is no kink in hose and this morning put some sink and plug hole unblocker down sink in case there was a blockage there. It has made no difference, Except water has mostly drained away but not completely.
