The Door Gasket is an OEM part for Whirlpool dishwashers. This gasket is designed to create a watertight seal around the dishwasher door, preventing water from leaking out during wash cycles. It ensures that the dishwasher operates efficiently by keeping water inside the unit, maintaining optimal cleaning performance, and protecting your kitchen from water damage.

Causes of a bad door gasket can include regular wear and tear from frequent use, exposure to high temperatures and harsh detergents, or damage from debris and foreign objects. Over time, these factors can lead to the gasket becoming brittle, cracked, or deformed, compromising its sealing ability.

Symptoms of a bad door gasket include:

• Water leaking from the dishwasher door during or after a cycle
• Visible cracks, tears, or deformities in the gasket
• The dishwasher door not closing properly or requiring extra force to close
• Mold or mildew buildup on the gasket

Symptoms of a bad corner deflector include:

• Water leaks or moisture inside the cabinet below the dishwasher
• Puddles or drips near tub corners after cycles
• Mineral residue or pooling in lower tub corners

Replacing the corner deflector with a new OEM part restores a tight seal to prevent water from entering cracks and causing leaks or damaged components inside the cabinet.
