Parts for Kitchenaid KDTM404KBS0: Upper Wash And Rinse Parts

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 Retainer is an OEM part for Whirlpool dishwashers. It securely holds the top spray arm in place underneath the dishwasher interior roof panel.

Causes of a bad retainer include cracking, breaking or deforming from repeated use and natural wear over time.

Symptoms of a bad top spray arm retainer are:

• Loosening or detachment of the upper spray arm during washing cycles
• Reduced or uneven water coverage for upper rack dishes
• Potential rattling or noise from an unsecured spray arm

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

The Top Spray Arm is an OEM part for Whirlpool dishwashers. It serves an important role on the upper rack, directing a spray of water across dishes during the wash cycle to thoroughly clean all surfaces. As a rotating component, the top spray arm endures constant motion which can cause wear over time.

Causes of a bad top spray arm include deterioration or cracks in the plastic from extended use, or blockages that restrict water flow.

Symptoms of a bad top spray arm include:

• Incomplete cleaning of upper rack dishes
• Buildup of food debris or grime that won't rinse away
• Noticeably weaker spray pattern from the arm nozzles

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

The Manifold is an OEM part for Whirlpool dishwashers. It directs water from the inlet valve through internal tubing to crucial components such as the pump, arms, and dispenser. As the central water manager, the manifold ensures each cycle stage receives water at the right temperature and pressure. 

Causes of a bad manifold can include cracks, distortions, or obstructions restricting water flow over many cycles.

Symptoms of a bad manifold include:

• Slow or inefficient washing and rinsing 
• Water not reaching all parts of the dishwasher
• Leaks or puddling around the valve area
• Abnormal sounds originating from the manifold

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, and Kenmore models.

This diverter directs dishwasher wash water to the upper spray arm, restoring proper water distribution for the top rack. Replacing a worn or broken diverter helps recover consistent spray coverage and cleaning performance. What it does:

• Ensures even water distribution for improved cleaning of items on the upper rack.
• Helps correct symptoms such as poor cleaning on the top rack or reduced spray to the upper spray arm.
• Works with the dishwasher's spray system—operates with water pressure from the pump to route flow.

• Disconnect power and shut off the water supply to the appliance before servicing.
• Use basic hand tools and follow the appliance's service diagram; avoid forcing tabs or fittings.
• Inspect nearby seals, gaskets and mounting tabs during replacement and replace if damaged.
• After installation, run a short cycle to check that the upper spray arm receives water and check for leaks.
