Parts for Whirlpool WDF730PAYM2: 07 - 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 feed tube assembly routes wash water up the back wall of your dishwasher to the upper spray system, restoring balanced spray pressure and coverage on the upper rack when the original tube is cracked, warped, leaking, or obstructed. What it does:

• Directs water from the circulation pump to the upper spray system via the rear manifold/docking port
• Maintains a sealed path to prevent internal leaks and pressure loss
• Damage or clogs can cause poor top-rack cleaning, weak spray, noisy operation, or residual detergent
• Visible cracks, broken tabs, or leaks at the rear wall indicate replacement is needed

• Feed tube assembly

• Disconnect power and shut off the water supply before servicing
• Open the door and remove racks as needed; release screws/clips securing the rear feed tube and detach from the docking port
• Transfer any reusable seals or brackets; align and secure the new tube without overtightening plastic fasteners
• Run a short cycle to check for leaks and proper upper-spray operation

The Upper Spray Arm is an OEM part for Whirlpool dishwashers. It is responsible for distributing water throughout the upper part of the dishwasher during the wash cycle, ensuring dishes are cleaned effectively.

Causes of a bad upper spray arm can include clogging from food particles, mineral deposits from hard water, or physical damage to the spray arm. These issues can impede the spray arm's ability to rotate and distribute water properly.

Symptoms of a bad upper spray arm include:

• Poor cleaning performance on the top rack
• Spray arm not spinning
• Visible damage or clogging of the spray arm holes

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

Note: For the spray arm retainer, use part number WP3400918.

The Retainer is an OEM replacement part for Whirlpool built-in dishwashers. It is a plastic clip located within the lower wash arm assembly. This retainer securely holds the pivot hub bearing and ensures smooth oscillation of the lower wash arm during cycles.  

Causes of retainer failure commonly relate to plastic material degradation from regular heat and chemical exposures over many uses. Crack propagation weakens the clips ability to precisely position bearing elements.

Symptoms of an inadequate retainer may include:

• Grinding or scraping noises coming from the wash arm area
• Restricted movement or binding of the lower spray arm assembly
• Potential loose wash arm parts that could interrupt spray patterns  

This OEM Whirlpool replacement is also compatible with KitchenAid, Maytag, and some Sears/Kenmore dishwashers. 

The Dishwasher Manifold is an OEM replacement part for Whirlpool dishwashers. It is a network of internal pipes and valves that distribute water throughout important washing components like the spray arms. The manifold works to carefully regulate water pressure and direct water flow during different phases of the cleaning cycle.

Symptoms of a bad manifold include:

• Insufficient or uneven water coverage inside the dishwasher
• Difficulty filling or draining the unit properly
• Leaks from internal pipes or valve connections
• Reduced washing or rinsing performance

Causes of a bad manifold can be mineral buildup inside small pipes over time, cracks in plastic components, or wear and tear of rubber seals and valve mechanisms.

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

The Middle Spray Arm is an OEM replacement part for Whirlpool dishwashers. It is an integral component responsible for thoroughly washing dishes in the middle rack. Through its specially designed spray nozzles, the middle spray arm provides precise coverage for optimal cleaning.  Color: light gray. It measures approximately 19 inches wide.

Causes of a bad middle spray arm can include clogging or mineral buildup that blocks the spray nozzles over time. Damage, such as bent or broken arms, is another potential cause.

Symptoms of a bad middle spray arm include: 

• Dirty dishes remaining in the middle rack even after a cycle  
• Noticeable decrease in water pressure to the middle rack
• Spray from nozzles only partly hitting intended dish surfaces
• Arm mobility issues that prevent rotation during the cycle

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