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

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

The Deflector is an OEM replacement part for Whirlpool dishwashers. Located in the lower corners of the tub, this component works to prevent leaks by keeping water from entering the cracks along the tub edges.

Causes of a bad corner deflector can include cracks, chips, or breaks from repeated impact or stress over time. Mineral buildup can also cause deflectors to warp or become misshapen, reducing their effectiveness.

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.

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

The Rubber Washer is an OEM part for Whirlpool dishwashers. This washer plays a role in ensuring a leak-proof seal at various connection points within the dishwasher, such as at the water inlet valve or hose connections. Its primary function is to prevent water from leaking out of the dishwasher during operation, thereby ensuring efficient and safe use of the appliance. 

Over time, rubber washers can deteriorate due to the constant exposure to water and chemicals found in dishwasher detergents. 

Symptoms of a bad Rubber Washer in a dishwasher include:

  • Visible signs of wear or damage to the washer, such as cracks, brittleness, or deformation.
  • Water leaking from the dishwasher, particularly around areas where hoses and valves connect.
  • A decrease in dishwasher performance due to water not being contained properly during cycles.

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

Thermostat has 1/4 inch terminals.

The High Limit Thermostat is an OEM part for Whirlpool dishwashers. This safety feature is designed to prevent the dishwasher from overheating by shutting off the power if the internal temperature exceeds a certain limit. It acts as a safeguard against potential hazards, such as fires, and ensures the dishwasher operates within safe temperature ranges. 

Over time, the high limit thermostat can become defective due to normal wear or electrical issues within the dishwasher. A malfunctioning thermostat may not accurately respond to temperature changes, which can lead to overheating or the dishwasher not reaching the necessary temperature for optimal cleaning.

Symptoms of a bad High Limit Thermostat include:

  • Dishwasher not starting or completing a cycle
  • The dishwasher stops heating water, affecting cleaning performance
  • Overheating, which could potentially damage dishes or the dishwasher itself

This OEM Whirlpool part can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances.

This is a genuine lock nut replacement. This is a general piece of hardware that is often used on several types of lawn and garden equipment, including in engines, housing, and other areas. The exact application of this part will vary based on the unit. The lock nut is used to create a more secure seal than a standard nut. When properly secured, the lock nut tightens to a bolt and uses an extra locking washer with teeth to ensure a snug fit.If lock washers do get damaged or lost, they need to be replaced immediately with a genuine OEM replacement. This model is compatible with all types of machines and units since it is a generic part. The washer is sold as an individual part and manufactured by Whirlpool. Lock nuts will need to be installed using a socket wrench or adjustable wrench. Pliers, a screwdriver, or another socket wrench will be needed to hold the bolt while the lock nut is being secured in place. Be sure to thread the lock nut carefully to ensure a strong seal and avoid stripping the bolt or the nut.
