Zanussi 1400 xcapacity FLE1416w washes empties but stops on spin cycle?

My washer washes and empties but then it stops on spin cycle when I take washing out it's wet through. Filter is full of water. I emptied filter 2 washing up bowls full and emptied washer and set it to empty and water went out of washer. I half filled it with the wet washing set it to spin and it goes round a couple of times then stops. Door locked. It's been 20 minutes now and every 3 or 4 minutes it spins about twice then stops.
