Customer Questions and Answers for Lower Door Seal by Bosch

The Lower Door Seal is an  OEM replacement part for Bosch dishwashers. It provides a water-tight barrier around the perimeter of the lower dishwasher door during cycle operation. Proper sealing is necessary to contain high-temperature water, steam and noise within the wash chamber.

Causes of a bad lower door seal can include deterioration of the sealing material over many years of use and exposure to hot chemicals. Physical damage such as tears or compression marks from over-tightening the door may also compromise sealing ability.

Symptoms of a bad lower door seal include:

• Puddles or leaks at the base of the dishwasher door
• Excess moisture, mineral deposits or mold growth outside the unit
• Inability to reach high temperatures or pressure inside the chamber
• Noise complaints as sound escapes during washing

This genuine Bosch OEM part is also compatible with Thermador, Gaggenau, and some Kenmore models.
