The Affresh Dishwasher Cleaner is an OEM accessory designed specifically for Whirlpool brand dishwashers. This citrus-scented tablet removes residue, odor-causing soils, and food particles from the dishwasher tub and gasket area during the cleaning cycle. Symptoms of a buildup include unwanted odors emanating from the dishwasher, especially after opening the door. Over time, residue and grime accumulate in hard-to-reach areas and provide an environment for mold and mildew growth.

Regular cleaning helps prevent this by removing leftover soils before they harden or encourage bacterial activity. The Affresh tablet utilizes a unique blend of cleaning ingredients that target soils and biofilms through a combination of powerful scrubbing action and natural cleaning enzymes.

As the #1 recommended dishwasher cleaner brand, Affresh is also compatible for use in Maytag, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and select Kenmore dishwashers for consistent cleanliness and freshness. The package includes six tablets 4.2 ounces

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.

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.

Symptoms of a bad hose clamp include:

• Leaks at the hose connection points
• Hoses slipping off the connections
• Visible rust or damage on the clamp

The Insulation is an OEM part for Whirlpool dishwashers, specifically engineered to enhance the appliance's efficiency by reducing heat loss and minimizing noise. This insulation wraps around the dishwasher, acting as a barrier that keeps heat within the appliance during cycles and dampens the sound of its operation, making for a quieter kitchen environment.

Causes of a bad insulation part can include wear and tear over time, moisture damage leading to mold or mildew buildup, or physical damage from pests or mishandling during installation or repairs. 

Symptoms of inadequate insulation include:

• Noticeable increase in the dishwasher's noise level
• Exterior surfaces of the dishwasher feeling warmer than usual
• Longer wash cycles due to inefficient temperature maintenance

• Maintains spring tension to resist vibration during normal operation
• Replaces a missing, bent, or weakened retainer
• Common symptoms: loose or wobbly knobs/trim, parts slipping off, or a retainer that won't stay on

• 1 push retainer

• Disconnect power; for gas appliances, also shut off the gas supply

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.
