My washer no longer completes a cycle? Hotpoint Aquarius WDL540?

My washer dryer is just out of guarantee (last week!) but its just stopped working properly. I usually put it onto the wash and then dry cycle but today it didn't get past the rinse part. I opened the door and all the water spilled out! I tried putting the drain function on its own and it didn't do anything. Any help would be really appreciated! x
