Customer Questions and Answers for Door Gasket (Dishwasher Side And Top Seal) by Bosch

This dishwasher door gasket seals the sides and top of the tub opening to keep water and steam contained during a cycle. Replacing a worn seal helps stop leaks at the door edges and restores quiet, efficient operation.

• Forms a watertight seal between the door and the tub perimeter
• Helps prevent dripping or puddles at the front corners and along the sides
• Maintains proper wash pressure, temperature, and noise isolation
• Replace if torn, flattened, brittle, or if moisture escapes around the door

• Disconnect power; if uninstalling the dishwasher, also shut off the water supply
• Open the door and pull the old gasket straight out of the channel
• Clean the groove; warming the new gasket in hot water can help relax bends
• Start at the top center and press the gasket fully into the channel without stretching; close the door to seat the seal and run a test cycle to check for leaks
