This tub ring (impeller) is the molded plastic ring that helps direct water flow under the wash plate so the washer agitates and rinses properly. Replacing a worn or damaged ring can restore normal wash action and performance. What it does

• Directs and channels water flow beneath the wash plate to support agitation and rinsing.
• Helps maintain balanced water movement for consistent cleaning.
• Worn or broken rings can contribute to poor agitation, clothes remaining soapy, or unusual wash-cycle noise/vibration.
• Works as part of the washplate/agitator assembly to ensure proper water circulation.

• One tub ring/impeller

• Disconnect power to the washer before beginning any repair.
• Remove the wash plate/agitator per your model's service instructions to access the ring.
• Install the ring in the correct orientation and verify it seats fully on the hub; do not force or deform the part.
• After reassembly, run a short test cycle to check for leaks or abnormal noise.

This syphon breaker prevents dirty drain water from being siphoned back into the dishwasher, helping maintain proper draining and protect wash water from contamination. It's a direct-replacement drain air-break for compatible dishwashers. What it does:

• Stops backflow/siphoning from the household drain into the dishwasher
• Helps maintain proper drain performance and prevents wastewater re-entry
• Can reduce odors and cloudy or soiled dishes caused by contaminated wash water
• Works as part of the dishwasher's drain plumbing to preserve wash hygiene

• Disconnect power to the appliance and turn off water supply before servicing
• Replace only with identical part and ensure correct hose routing and secure clamps
• Inspect adjacent drain hoses and connections; replace damaged hoses or clamps as needed

Kit contains two 10 feet inlet hoses.

This lower wire harness connects and routes electrical circuits for the appliance's lower service area, restoring reliable power and signal flow to dispensers and lower controls. It's a direct-fit replacement when the original harness is damaged. What it does:

• Routes and links power and signal wires between lower components and the main control
• Replaces frayed, pinched, or broken wiring that can cause intermittent or no operation
• Helps resolve symptoms such as non-working lower dispenser functions, loss of lights, or erratic component behavior
• Maintains connector fit and OEM routing for proper electrical performance

• Disconnect power (and water if applicable) before starting any repair
• Inspect connectors and terminals for corrosion; replace if found
• Follow for routing and securing the harness to avoid pinch points
• Do not splice or modify the harness; use the exact replacement for safety and proper operation

This drain hose coupling kit connects the washer drain hose to the appliance drain outlet, restoring a secure, leak-resistant hose connection and preventing water leaks during drain cycles. What it does:

• Provides a replacement coupling to join the drain hose to the washer drain outlet
• Re-establishes a tight hose connection to reduce leaks and water damage
• Addresses symptoms such as leaking at the drain connection or a loose hose fit
• Compatible with affected Whirlpool top-load washer drain assemblies

• Unplug the appliance before servicing and work on a dry surface
• Remove the old coupling and inspect the hose and outlet for damage before installing
• Ensure the hose is fully seated and secure with the existing or supplied clamp(s)

This ground wire provides a safe chassis connection to restore proper grounding and reduce shock and electrical-fault risk. It replaces a frayed, corroded or missing ground lead to help keep the appliance electrically safe. What it does

• Connects the appliance chassis to the grounding system to prevent stray voltage on metal surfaces
• Restores a secure ground path if the original wire is broken, loose, or corroded
• Helps stop intermittent power faults or nuisance tripping caused by a compromised ground
• Addresses symptoms like visible wire damage, loose ground connection points, or grounding-related electrical issues

• One ground wire

• Always disconnect power (unplug or shut off the circuit breaker) before starting work
• Attach the ring/terminal ends to the designated chassis ground screw and the equipment ground point
• Route the wire away from moving parts, heating elements, and sharp edges; secure with existing clips or fasteners
• If terminal hardware is missing or damaged, replace with equivalent OEM-style fasteners and torque to specification

Outer tub assembly includes: outer tub, tub seal, drive shaft and bearings. To rebuild the tub, order the bearing and tub seal kit W10435302 and the bearing installation tool W10447783. When replacing this part, if you see that your motor stator is broken, search by your model number to make sure you get the right stator for your model.

This is a replacement 8-18 threaded screw used to secure components in compatible Whirlpool appliances. It provides a like-for-like fastening option when an original screw is lost or damaged, restoring proper fit and function. What it does:

• Fastens panels, brackets, or components where an 8-18 thread screw is required
• Replaces stripped, corroded, or missing screws to stop rattles and looseness
• Matches the fastening method used by the original equipment for reliable hold
• Suitable for areas where the OEM specified an 8-18 threaded screw

• Screw (single)

• Use the correct driver and size to avoid stripping the head or damaging mating threads
• Tighten to snug fit; avoid over-torquing which can strip threads or crack plastic parts
• Disconnect power to the appliance before starting repairs when working near electrical components

This plate stator is the stationary motor plate used in compatible Whirlpool appliance motor assemblies. It supports the motor's stationary components so the motor can run smoothly and reliably. What it does:

• Secures and positions the motor's stationary winding and magnetic components
• Helps maintain correct air gap between rotor and stator for proper motor function
• Can contribute to noisy motor operation or failure-to-start when damaged
• Supports consistent motor rotation and reduces abnormal vibration

• Disconnect power to the appliance before starting any repair.
• Removal typically requires disassembly of the motor housing; retain fasteners and note orientation.
• Handle carefully—edges and mounting holes can be sharp and fragile.

This is a genuine replacement mounting screw that secures appliance components and panels so parts stay aligned and stable. Installing the correct screw restores proper fit and helps eliminate vibration or loose panels. What it does:

• Fastens panels, brackets, or small components in place
• Replaces missing, stripped, or damaged screws that cause loose parts
• Helps stop rattling, vibration, or misaligned panels
• Restores secure connections after repairs or part replacement

• One mounting screw

• Unplug the appliance or disconnect power before starting work
• Use the correct screwdriver bit to avoid stripping the head
• Tighten until snug; avoid over-tightening which can strip threads or crack plastic
• Keep removed hardware organized so you can reuse existing screws when applicable

This clamp secures a washer or dryer hose to its connection to prevent leaks and keep the hose firmly in place during operation. It replaces worn or loose clamps that allow water to escape or hoses to detach. What it does:
