Are you sure it's from the door? I have the same problem - thought it was coming from the door but actually it's coming from the water inlet/powder tray. It runs down behind the door and drips out at the bottom of the door. I haven't found a solution yet but looking at other postings on the web it seems like a common problem, the water inlet is too near the front of the machine and water spills out of the powder tray and finds it's way out of the front.
