Hotpoint DWF60 Dishwasher problem?

My hotpoint dishwasher DWF60 has stopped working, If i put the dishwasher on it runs as if it is going to work but after a few minites it stops and whatever cycle its on the indicator light just flashes constantly. I did notice that the salt had solidified and have poured hot water in to disperse the salt and it ran for a bit longer but still wont complete a full cycle. Any help would be much appreciated.
