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
What's included:
  • Feed tube assembly
Install notes:
  • 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 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 Arm Spray is an OEM part for Whirlpool dishwashers. This component is crucial in the dishwasher's ability to effectively clean dishes, as it distributes water evenly throughout the unit during a wash cycle. Located beneath the upper rack, the arm spray rotates and sprays water at a controlled pressure and angle, ensuring that all dishes, regardless of their placement, are thoroughly washed.

Causes of a bad arm spray include clogging from food particles or mineral deposits from hard water, physical damage that can prevent it from spinning, and wear that reduces the effectiveness of the spray holes.

Symptoms of a bad arm spray include:

  • Dishes remain dirty or spotty after washing
  • Decreased water pressure in the spray
  • Unusual noise during operation as the arm struggles to rotate

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