Indesit Washer fills then empties then the dial keeps clicking round?

My Indesit WM12X fills sits there, makes 3 burps, then empties. The dial then starts to click round and doesn't stop until washer is swtiched off. I've tried to reset i.e. turning the dial to a black spot then switching the machine on and then off. But when I set a programme again it goes through the fill, burp 3 times, then empties. The drum never turns.
