Louise, the sealing rubber will always pass water between itself and the door - they are designed that way. The frame is designed to drain through 2 routed holes that you can see if you open the door and look at the threshold (lower part) where the door seals up to. My guess is that the may be blocked. See if there is any visible debris in them, then slowly pour a jug full of water into the groove of the frame and see if it comes out between frame and cill on the outside, or if you have no cill, through the face drain caps.If nothing comes out and it overflows int the house, they are deffo blocked.
