Take the bottom kick plate off, but DO NOT undo the filter housing! Just to the right of the filter is a black rubber tube with a white plastic stopper in the end of it - this is the drain point. Get a hose pipe ready, put a plastic sheet on the floor, quickly pull out the stopper, and push the drain pipe into the hose pipe (mine was a perfect fit). Once the water has drained out of the hose pipe, the door will open. All you have to do now is figure out why it won't spin to pump out the water - when you find out, let me know, because mine has done exactly the same thing!
