My aquarius FDW60G sounds like it's boiling?

Any help would be appreciated here. The dishwasher stopped today while I was out. My daughter said some lights were flashing and turned it off. When I checked there was water in the bottom. I turned it back on and it drained fine, sounded like water was going in again but then it sounded like it was boiling. Inside, there was water sat there again but the inside of thefront door was dry. There was a little water on the floor of the machine, behind the kick plate. The filter, waste pipe, mains water pipe are all clear. The salt is full. Help! It gets water in, it drains water out to the drain, it just wont progress from filling the bottom and heating that water.
