Robert - I am not an expert. But the door will not open if there is still water in the machine. If you have a door hatch fitted you can open it to clean the pump and release the water. Usually, it is on the front of the machine low down. You may be able to release the water from here. But you will need a large tray to catch it in. It will then allow you to open the door and retreve your clothes.
