If it is leaking at the end of the drain hose at the union to the "U-piece", (the bit that hangs over the sink), just remove the "U-Piece from the end of the hose. You may need to fit aclip around U-piece to shape the hose so that it does not fall out of the sink. Miele had them for their older dishwashers, eg G527.
