This O-ring seal fits into a groove to create a tight, leak-resistant barrier where two parts join. Replacing a worn O-ring helps stop drips at connections and keeps your appliance running reliably. What it does:

• Forms a compressible seal between mating parts (fittings, housings, or tubing)
• Helps prevent water or fluid leaks at joints
• Maintains proper pressure and flow within the sealed path
• Replace if you see seepage at the connection or the ring is cracked, flattened, brittle, or swollen

• 1 O-ring seal

• Disconnect power and shut off water supply before servicing
• Clean the groove and mating surfaces; remove debris that could compromise the seal
• Lightly lubricate with manufacturer-approved silicone grease; avoid petroleum-based products
• Seat the O-ring without twisting; reassemble carefully and check for leaks after testing

The Tub Wheel supports and guides the washer's tub assembly on its base during wash and spin cycles. Replacing a worn wheel restores smoother, quieter operation and helps reduce vibration and rubbing as the machine operates.

• Provides rolling support so the tub can move and self-balance during cycles
• Reduces friction between the tub and the base/frame
• Helps keep the tub centered to minimize noise and vibration
• Failure symptoms include squeaking or grinding, scraping noises, dragging movement, or visible flat spots/cracks on the wheel

• Disconnect power and water supply before servicing; wear appropriate gloves and eye protection
• Access the base/suspension per the service information and support the tub to remove load from the wheel
• Remove the retainer/axle, install the new wheel, and free rotation and correct orientation
• Reassemble, level the appliance, and run a spin test to check for noise and balance

Screw: 8-16 x 3/8 inch.

This replacement screw secures appliance panels, brackets, and components. Using the correct size restores a snug fit to reduce vibration, prevent loosening, and keep assemblies properly aligned during operation. What it does:

• Fastens sheet metal and component brackets in designated locations
• Replaces missing, stripped, or corroded hardware
• Helps eliminate rattling and vibration from loose panels
• Maintains proper alignment of covers and assemblies

• 1 screw

• Disconnect electrical power; shut off water or gas supplies if applicable
• Match length/thread to the original; replace one fastener at a time to preserve alignment
• Start by hand to avoid cross-threading; use the correct driver size
• Snug firmly but do not overtighten to prevent stripping

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.

• Disconnect power and water (if applicable) before beginning any repair.
• 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.

A small replacement retainer clip used to secure exterior trim and interior panels on compatible Whirlpool appliances. Restores proper panel fit and prevents rattling or loose trim for a cleaner, safer operation. What it does

• Secures trim, panels or components in place to maintain proper alignment
• Helps stop rattling, vibration noise and loose-fitting parts
• Keeps seals and covers positioned so doors and panels close correctly
• Simple, single-purpose hardware used where a clip-style fastener is required

• One retainer clip as pictured

• 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 electric heating element generates the high heat needed for your appliance to reach operating temperatures, restoring normal heating performance and cycle effectiveness. Use the correct replacement for safe, reliable heat output. What it does:

• Heats the appliance's air or oven cavity so cycles reach intended temperatures
