This wire harness is a factory-style electrical assembly that routes power and signals between controls and components to restore reliable operation. It replaces a damaged or worn harness to help eliminate intermittent connections and electrical faults. What it does:

• Carries power and control signals between the control board and appliance components
• Restores reliable electrical connections if wires are frayed, broken, or connectors are loose
• Helps resolve intermittent operation, components that don't respond, or power-related failures
• Maintains correct routing and strain relief to prevent chafing and short circuits

• Disconnect power (unplug or shut off breaker) before beginning any repair to avoid shock or injury
• Verify harness routing and connector orientation match the original during installation
• Replace only with the correct harness to ensure proper connector fit and function

This spacer positions and supports the appliance tank/tub assembly to maintain proper alignment and spacing for reliable operation. Replaces a worn or damaged spacer to restore correct fit and reduce movement. What it does:

• Keeps the tank/tub assembly correctly spaced and aligned with the cabinet and mounting points
• Helps prevent rubbing, binding, and excess vibration caused by a missing or damaged spacer
• Restores proper clearance to support seals and hoses that rely on correct tank positioning
• Useful when reassembling the appliance after service or repair

• One spacer

• Disconnect power and water supply before starting any repair
• Access may require removal of outer panels, console, or access covers depending on model
• Handle parts carefully to avoid damaging surrounding seals and wiring; reuse fasteners unless replacement is specified

A flat washer used with fasteners on select top-load and front-load washer assemblies to distribute load and prevent loosening. Replaces worn or missing washers to help stabilize mounting points and reduce vibration where metal parts join. What it does:

• Provides a smooth bearing surface between a bolt or nut and the mating part
• Helps distribute clamping force to prevent damage to housings or panels
• Reduces loosening from vibration or thermal cycling
• Common fix when mounting hardware is loose, rattling, or causing leaks at joins

• Inspect mating bolt, nut, and surface for wear or damage before installing
• Use correct size and orientation; do not overtighten fasteners
• Disconnect power to the appliance and follow safety procedures when accessing internal parts
• Replace all related fasteners to ensure proper fit

The Door Hinge (RH) is an OEM replacement part for Whirlpool dishwashers. This hinge is installed on the right-hand side of the dishwasher door, allowing it to open and close smoothly while maintaining the proper tension and alignment. The hinge plays a crucial role in ensuring the door seals securely during operation, preventing leaks and enabling efficient cleaning performance.

Common causes include regular use leading to wear and tear, accidental impacts, or exposure to moisture, which can contribute to rust or corrosion.

Symptoms of a bad door hinge include:

• The dishwasher door not closing completely
• Difficulty opening or closing the door
• A sagging or misaligned door
• Unusual noises when moving the door

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

Replace a damaged rack and restore smooth loading with this dishrack. It securely holds dishes and cookware during the cycle, helping prevent tipping and flaking rust from worn coating so items stay stable and protected.

• Supports and organizes dishes, bowls, cups, and cookware throughout wash and rinse cycles
• Slides on the rails for easy loading and unloading
• Helps keep items upright to maintain spray coverage and prevent shifting
• Replace if you see rusting/coating loss, broken or missing tines, bent frame, or the rack no longer moves smoothly

• Disconnect power and water to the dishwasher before servicing
• Pull the rack fully out; release rail end caps or stops if present, then remove the old rack
• Transfer any reusable parts (rollers, clips, baskets, or tines) from the old rack to the new rack
• Seat the new rack on the rails and verify smooth travel before use

This manifold routes flow from the appliance's supply to downstream components, restoring proper distribution and reliable performance. Replacing a cracked or obstructed manifold can stop leaks and help resolve weak or inconsistent operation.

• Directs flow from the inlet to the appropriate branches within the system
• Helps maintain correct pressure and delivery to connected components
• Seals at connection points to prevent drips and leaks
• Typical failure signs: visible cracks, leaks at joints, weak output, or intermittent performance

• Disconnect power and shut off the appliance's supply (water or gas, as applicable) before servicing
• Note orientation and transfer any reusable seals, clips, or fittings from the original part if required by your model
• Inspect O-rings/gaskets; replace any that are brittle, flattened, or damaged
• Restore supply and run a test cycle; check all connections closely for leaks

The Filter Screen is an OEM component specifically designed for Whirlpool dishwashers. Located inside the sump area, the durable mesh screen captures small food particles and debris before wash water is recirculated through cycles.

Symptoms of a bad filter screen can include clogging obscuring openings over time, degrading mesh no longer inhibiting passage, or dislodging from mounting points allowing bypass.

Causes involve the normal accumulation of soils requiring periodic cleaning. Mineral buildup may eventually cement sections together reducing effectiveness. 

Symptoms of a bad filter screen include:

• Dirty or soiled wash water unable to fully circulate  
• Filth dispersing throughout the wash cabinet interior
• Reduced cleaning and unsatisfactory dish results

This OEM Whirlpool part is also compatible with KitchenAid, Maytag, Jenn-Air, Amana, and some Kenmore dishwasher models. Replace to maintain built-in wastewater filtration protecting major components.

This thermostat bracket secures the refrigerator/freezer temperature sensor or thermostat to the cabinet, keeping the sensor in the correct position for accurate temperature control. Durable replacement for factory mounting hardware. What it does:

• Holds the thermostat/temperature sensor in place so it reads interior temperatures correctly
• Helps prevent loose or misaligned sensors that can cause irregular cooling or cycling
• Restores proper sensor positioning after damage or broken mounting clips
• Works with the thermostat assembly to maintain consistent appliance operation

• One thermostat mounting bracket

• Disconnect power to the appliance before service to avoid electrical shock
• Handle thermostat/sensor elements carefully; avoid bending or pinching the sensing tube
• Retain or reuse original fasteners unless replacement hardware is explicitly included
