My dishwasher blew a fuse which I changed and the dishwasher worked. I noticed the next day I had a slight leak which I sorted - must of bumped hose when changing fuse. The following day the pre wash and drying light continuously flashed, tried various thing eventually pulled plug from wall for 5 mins dishwasher worked ok. The next again day On/Off button comes on but it wont let me select a programme. If I hold down the start button it makes a continuous bleep for 3 secs but nothing happens when I hold down the programme key. Can you help, PLEASE
