My Bosch WVF 2401 washing machine/dryer has stopped draining?

I put a small rug in the washing machine today and after the cycle had finished I opened the washing machine door and water flooded out onto the kitchen floor. No water is draining away. I've tried it since on 2 different spin/drain cycles but still the water is in the machine.
Help, please!
It's a Bosch WVF 2401 washing machine with dryer cycle.
