I have Gaggenau dishwasher GM 286-720. It has a water leak from the drain pump housing. The Appliance Parts Pro schematic drawing differs from the actual machine, so having trouble specifying part needed. I believe the necessary part is the pump housing seal. It seals the housing that the impeller operates in. The seal is a flat rubber seal bigger in diameter than a silver dollar. It has a hole in the middle for the drain motor shaft. There is a raised portion in the center of the seal that would rub/seal against the back side of the impeller. Please let me know if you can supply this seal or an assembly that would include this seal. I can e-mail a photo of the seal if necessary, maybe you would have a picture of the part in your data. Your help is appreciated. Call if questions. Thanks, Dick Belfry 952-939-9282.
