First time on a site like this so Still a little rubbish at it but here goes. I have a Hotpoint BF1620 dishwasher. I put it on a cycle last night but woke to find it had not washed and the pump still somehow seemed to be struggling to drain. I've since put plenty of water in the base and switched on and it drains fine but then beeps and the left hand light flashes and the pump seems to continue trying to drain water that's not there. Lost my manual so not a clue what this means. It won't let me re set it unless I leave it switched off for a while, when I do everything looks fine but then does it allover again It showed no signs of any problem until this. Any ideas?????
