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

The Dishwasher Food Chopper is an OEM part for Whirlpool dishwashers. It's designed to break down food particles that are washed off dishes during the cleaning cycle. This prevents large debris from clogging the dishwasher's drain and ensures that water remains clean throughout the cycle, enhancing the machine's cleaning efficiency. 

A malfunctioning or worn-out food chopper can lead to several problems, such as poor cleaning results due to food particles being redeposited on dishes, or even clogs that can strain the dishwasher's pump and filters. 

Symptoms of a bad Dishwasher Food Chopper include:

• Dishes coming out with food particles still on them
• The dishwasher making unusual noises indicating a struggle or blockage
• Water not draining properly, suggesting a possible clog

This OEM Whirlpool part can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances.

The Circulation Motor is an OEM part for Whirlpool dishwashers. It is responsible for pumping water through the spray arms to ensure thorough cleaning of dishes during the wash cycle. This motor helps maintain consistent water pressure and flow, crucial for effective dishwashing performance.

Over time, the circulation motor can fail due to factors such as motor wear, electrical issues, or blockages that cause the motor to overheat or become damaged. Regular use and the buildup of debris or hard water deposits can also contribute to motor failure.

Symptoms of a bad circulation motor include:

• Poor cleaning results
• Unusual noises during the wash cycle
• Water not circulating properly
• Dishwasher not completing cycles

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

The Pump and Motor Assembly is an OEM part for Whirlpool dishwashers. This part is responsible for circulating water during the wash cycle and draining water at the end of the cycle.  

Causes of a bad assembly can include blockages from debris, electrical failures, or wear and tear from regular use.  

Symptoms of a bad Pump and Motor Assembly include:

• Dishes remaining dirty after a wash cycle
• Water not draining properly from the dishwasher
• Unusual noises during operation
• Error codes related to water flow or pump performance

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

This seal sits at the dishwasher's air/water inlet, creating a tight barrier where the inlet assembly meets the tub or door. Replacing a worn seal helps stop nuisance leaks and supports proper fill and venting performance. What it does

• Forms a watertight seal at the air/water inlet connection
• Helps prevent drips or seepage during fill and wash
• Supports correct venting to keep moisture contained inside the tub
• Common failure signs include water on the floor near the unit, dampness around the inlet/vent area, or a cracked, flattened, or brittle seal

• One air/water inlet seal

• Disconnect power and shut off water before servicing
• Access method varies by model; remove the inlet/vent cover or side panel to reach the seal
• Clean mating surfaces; seat the new seal evenly without distortion
• Reassemble and run a brief fill/wash to check for leaks

This run capacitor helps start and keep the motor running smoothly by providing the necessary phase shift and torque boost. A weak capacitor can cause hard starting, humming, or intermittent motor operation.

• Supplies continuous phase shift to maintain motor rotation
• Helps the motor start reliably under load
• Symptoms can include humming, slow or no start, or overheating shutdown
• Restores normal operation when the original capacitor has weakened

• Disconnect power before servicing; discharge the old capacitor safely
• Note wire locations and transfer leads to the new capacitor one-by-one
• Mount securely in the original bracket or location to prevent vibration
• If the motor still won't start, further diagnosis of the motor or start device may be required

This connector links mating components within the appliance to create a secure, reliable connection. Replacing a cracked or loose connector helps restore consistent operation and prevent intermittent issues caused by poor contact or separation. What it does:

• Creates a stable connection between mating parts or harnesses in the appliance
• Helps prevent looseness or separation that can disrupt performance
• Direct replacement for broken, brittle, or deformed connectors
• Can resolve intermittent operation traced to a poor connection at this junction

• 1 connector

• Disconnect power and, if applicable, shut off water before servicing
• Note orientation and positions before removal to ensure correct reassembly
• Seat the connector fully until any locking features engage; do not force
• Inspect mating parts for wear or damage and replace if necessary

Color: light blue. Measures about 1 inch high by 4 inches deep.

Replacement pump gasket with silicone sealing material that restores a watertight seal between the pump and housing. Helps stop leaks at the pump area and prevents water pooling under the appliance.

• Seals the pump to the housing to help prevent water leaks and drips.
• Common repair for visible water under the appliance or leaks coming from the pump area.
• Silicone sealing material provides a flexible, water-tight interface that conforms to the pump housing.
• Designed to replace the factory pump gasket for a direct fit and proper sealing.

• Disconnect power and water supply before beginning any repair.
• Remove the pump assembly to access and replace the gasket.
• Clean and dry mating surfaces before installing the new gasket; seat evenly to ensure a full seal.
