Specs: No.8X1/2 HEX WASHER HEAD

Color: Gray

The Lower Washarm is an OEM replacement part for Whirlpool dishwashers. Positioned at the bottom of the dishwasher tub, it rotates during the wash cycle, distributing water and detergent evenly across the lower rack. 

Over time, wash arms can become clogged with food debris or mineral deposits, reducing water flow. Physical damage such as cracks or warping can also impede the wash arm's rotation and affect its cleaning performance.

Color: Gray

Symptoms of a faulty lower wash arm include:

• Inadequate cleaning of dishes on the lower rack
• Uneven or inconsistent water spray
• Clogged or obstructed spray nozzles
• The arm not spinning or rotating correctly

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

This tub wheel mounts on the dishwasher's tub wall to guide and support the rack as it slides in and out. Replacing a worn wheel restores smooth rack movement and helps prevent binding, noise, and derailments.

• Mounts to the tub to provide rolling support for the dish rack/rail
• Replaces cracked, flattened, or missing wheels that impede rack travel
• Helps fix racks that stick, bind, are hard to pull/push, or derail
• Reduces grinding or squeaking from the rack area

• Disconnect power at the breaker before servicing
• Open the door and pull the rack forward for access
• Release the old wheel from its retainer/axle per your model's design; install the new wheel in the same orientation
• Ensure the wheel spins freely and the rack slides smoothly before use

Small replacement screw that secures panels and internal components on compatible appliances. Restores proper fastening to reduce rattling and loose parts so controls and panels stay aligned during normal use. What it does:

• Secures panels, brackets, and small components to the appliance frame or assemblies.
• Helps stop rattling, vibration-related noise, and movement from loose parts.
• Replaces a missing, worn, or stripped fastener to restore proper mounting.
• Used wherever the original manufacturer specified this screw in service diagrams.

• Disconnect power and water before working on the appliance to avoid shock or injury.
• Match the replacement screw to the original by fit and thread before installation; do not force mismatched fasteners.
• Start the screw by hand to avoid cross-threading; tighten securely but avoid over-torquing which can strip threads or damage components.
• Refer to the appliance's service manual or parts diagram for exact location and any torque or threadlocker recommendations.

A replacement tension spring designed to restore proper movement and return force to the appliance mechanism. Helps the affected component operate smoothly so doors, levers or assemblies move with correct tension and alignment. What it does:

• Provides return and holding tension for the appliance mechanism to restore normal movement.
• Helps reduce sagging, misalignment, or loose operation of the associated door or linkage.
• Minimizes noise and vibration caused by a worn or weakened spring.
• Works as the direct-fit part when the listed part number matches your appliance.

• Springs are often under tension—wear eye protection and use caution when removing or installing.
• Follow the appliance's service manual or OEM instructions for correct orientation and safe installation.

A replacement leveling leg that stabilizes your appliance and allows height adjustment for a secure, level install. Restores proper alignment to reduce rocking, vibration and uneven door gaps. What it does:

• Raises and levels the appliance so all feet contact the floor evenly.
• Stops rocking and excessive vibration that can cause noise or wear.
• Helps restore proper drainage and door alignment by correcting tilt.
• Matches original fit and function for reliable support.

• Disconnect power (and water for appliances with plumbing) before servicing.
• Raise or support the appliance safely before removing or adjusting legs.
• Turn the leg to raise or lower; make small adjustments and recheck level.
• Use common hand tools (wrench or pliers) and avoid forcing damaged threads.

• Fasten clip into the OEM mounting hole until it snaps or seats firmly
• Keep removed screws and small parts organized to avoid lost hardware

This is a machine screw used to secure appliance panels and components where an 8-32 thread fastener is specified. It provides a reliable hold for control panels, brackets, and interior assemblies. What it does:

• Fastens panels, brackets, and small components to the appliance chassis
• Holds control assemblies and trim pieces in place
• Maintains secure connections that prevent vibration-related loosening
• Works where an 8-32 coarse-thread machine screw of short length is required

• One 8-32 x 3/8" machine screw

This replacement rack track restores smooth, stable rack movement and keeps the oven rack aligned while sliding in and out. It helps prevent rack sagging, binding, or uneven travel so food and cookware stay level and secure. What it does

• Guides and supports the oven rack so it slides in and out smoothly.
• Prevents racks from sagging, tipping, or binding when pulled forward.
• Restores proper rack alignment to reduce scraping, catching, or loud banging.
• Works with standard oven/range racks that use a molded metal/plastic track system.

• High-level swap: remove the oven racks, unfasten the old track, and secure the replacement in the same mounting locations.
• Use appropriate hand tools and avoid forcing parts; aligning the track before tightening fasteners reduces binding.
• Disconnect power to the appliance or follow the manufacturer's safety guidance if servicing components near electrical connections.
