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

The Filter Screen is an OEM component specifically designed for Whirlpool dishwashers. Located inside the sump area, the durable mesh screen captures small food particles and debris before wash water is recirculated through cycles.

Symptoms of a bad filter screen can include clogging obscuring openings over time, degrading mesh no longer inhibiting passage, or dislodging from mounting points allowing bypass.

Causes involve the normal accumulation of soils requiring periodic cleaning. Mineral buildup may eventually cement sections together reducing effectiveness. 

Symptoms of a bad filter screen include:

• Dirty or soiled wash water unable to fully circulate  
• Filth dispersing throughout the wash cabinet interior
• Reduced cleaning and unsatisfactory dish results

Symptoms of a bad dishwasher gasket include:

• Water leaking from the bottom or sides of the dishwasher door
• Visible cracks or tears in the gasket
• The dishwasher door not closing properly
• Increased noise levels during operation

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
• Leaks from the dispenser area
