The Door Hinge (RH) is an OEM replacement part for Whirlpool dishwashers. This hinge is installed on the right-hand side of the dishwasher door, allowing it to open and close smoothly while maintaining the proper tension and alignment. The hinge plays a crucial role in ensuring the door seals securely during operation, preventing leaks and enabling efficient cleaning performance.

Common causes include regular use leading to wear and tear, accidental impacts, or exposure to moisture, which can contribute to rust or corrosion.

Symptoms of a bad door hinge include:

• The dishwasher door not closing completely
• Difficulty opening or closing the door
• A sagging or misaligned door
• Unusual noises when moving the door

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.

• Directs flow from the inlet to the appropriate branches within the system
• Helps maintain correct pressure and delivery to connected components
• Seals at connection points to prevent drips and leaks
• Typical failure signs: visible cracks, leaks at joints, weak output, or intermittent performance

Over time, the circulation motor can fail due to factors such as motor wear, electrical issues, or blockages that cause the motor to overheat or become damaged. Regular use and the buildup of debris or hard water deposits can also contribute to motor failure.

Symptoms of a bad circulation motor include:

• Poor cleaning results
• Unusual noises during the wash cycle
• Water not circulating properly
• Dishwasher not completing cycles

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.

Over time, the dispenser assembly can suffer from wear and tear, clogs, or damage to its components. Such issues can impede the proper dispensing of cleaning agents, negatively affecting the dishwasher's cleaning efficacy.

Symptoms of a bad dispenser assembly include:

• Detergent or rinse aid not dispensing properly
• The dispenser door not opening or closing correctly
• Residual detergent left in the dispenser after the wash cycle
