Symptoms of a failing pulley cover include:

• Inability to properly close or latch the cover  
• Leaks or debris entering the pulley compartment
• Interference with belt or pulley movement
• Loose fasteners or mounting points that cause misalignment

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

Symptoms of a bad screw include:

• Loose or detached rear bulkhead allowing side-to-side play
• Excessive noise and shaking felt through the surrounding walls   
• Development of micro-cracks around screw holes over time
• Potential leak paths if holes are no longer sealed

• Manages cycle timing, modes, and overall system logic
• Stores error logic and supports service diagnostics
• Helps protect the system by shutting down functions when faults are detected
• Common symptoms include no power or no response, intermittent operation, error codes/alarms, or components not running

• 1 electronic control board

• Disconnect power before servicing; observe ESD precautions and handle the board by the edges
• Photograph connections and move wire harnesses one at a time to the new board; confirm connector orientation and seating
• Transfer any jumpers, DIP switch positions, brackets, or mounting hardware from the original board as needed
• After installation, restore power and run the model's diagnostic or configuration steps per the tech sheet/service manual if applicable

Includes connector and both clamps.

This set of washer fill hoses connects your home's hot and cold water supply to the washer's inlet valves. Replacing aging hoses helps prevent leaks and ensures the washer fills properly for every cycle.

• Supplies hot and cold water from household faucets to the washer's inlet valves
• Helps address leaks, bulges, or cracks in old hoses
• Can resolve drips at fittings and water on the floor
• Improve slow or no-fill issues caused by kinks or internal blockages

• Unplug the washer and turn off both water supplies before starting
• Place a towel or pan to catch residual water; disconnect old hoses from faucets and inlet valves
• Attach new hoses to the correct hot/cold connections; tighten connections securely without overtightening
• Open valves, check for leaks at both ends, and re-tighten if needed

Contains two, six foot long braided hoses with 90 degree ends.

This replacement nut is a small hardware fastener used to secure components inside your appliance. It helps keep parts tight and properly aligned so assemblies don't loosen from vibration or normal operation.

• Threads onto a mating bolt, stud, or shaft to clamp parts together
• Maintains alignment and reduces movement and rattling
• Replaces a stripped, missing, or damaged nut to restore a secure fit
• Common signs of failure: loose panels or components, unusual vibration/noise, hardware missing

• Disconnect power; shut off gas and/or water if applicable before servicing
• Note the original hardware stack-up (washers/spacers) and orientation for reassembly
• Start by hand to avoid cross-threading; tighten to manufacturer guidance—do not overtighten
• Replace any damaged washers or locking devices

This dishwasher dispenser stores detergent and rinse aid and releases them at the correct points in the cycle to support consistent cleaning results. Replace a broken, stuck, or leaking dispenser to restore reliable detergent delivery.

• Holds detergent and rinse aid and dispenses them automatically during the wash and rinse portions of the cycle
• Door/actuator mechanism controls the timed release of detergent
• Seals help prevent leaks around the dispenser opening
• Typical failure symptoms: detergent cup won't latch or open, detergent left in the cup, rinse aid not dispensing, or leaks from the dispenser area
