This transmission pinion is the small drive gear inside the gearcase that meshes with the mating gear to transfer motor power through the drive. Replacing a worn pinion restores smooth operation and reliable torque delivery.

• Transfers rotation from the motor through the gear train inside the transmission
• Helps maintain proper speed and torque to the drive output
• Replaces stripped or broken teeth that cause slipping and chatter
• Typical symptoms: grinding/clicking noises, output that stalls or won't turn, metal shavings in grease

• Unplug the appliance before servicing; allow all moving parts to stop
• Access requires opening the drive housing/gearcase; note the orientation of shims, washers, and spacers
• Clean out old grease/debris and re-pack with manufacturer-approved grease
• Inspect mating gears, bearings, and shafts for wear; replace related parts as needed and follow the service manual for alignment

Hose washer and plastic insert for inlet hose. To order separately: for washer use WPY013783, for strainer use WP22002960.

This small retaining clip secures components in place inside the appliance, helping prevent movement, vibration, and premature wear. Replace a bent, fatigued, or missing clip to restore a solid, factory-tight hold.

• Holds panels, brackets, or tubing securely in their mounts
• Helps maintain alignment to reduce rattles, rubbing, or intermittent issues
• Common signs of failure: missing clip, loose fit, buzzing/vibration, parts that won't stay seated
• Restores proper retention after service, transport, or vibration-related fatigue

• Disconnect power and shut off gas/water before servicing
• Note the original clip's orientation; remove with needle-nose pliers
• Seat the new clip fully—do not over-bend; spring tension provides the hold

This 240V lid switch senses when the washer lid is closed so the cycle can run and spin safely. Replacing a failed switch restores reliable lid detection and prevents unexpected cycle interruptions due to a false "lid open" condition.

• Detects a closed lid to enable motor and spin functions
• Opens the circuit when the lid is raised for safety
• Failure symptoms: won't start, won't spin or agitate, or stops mid-cycle as if the lid is open

• Unplug the washer before servicing
• Confirm your model specifies the 240V lid switch; access it by lifting the top or removing the control console/top, depending on model design
• Transfer wiring and mounting exactly; route harness clear of moving parts and ensure the lid actuator fully engages the switch
• After reassembly, test start and spin with the lid closed; never bypass the safety interlock

Replacement lug stop that limits movement of a mechanical component to prevent over-travel and reduce wear. Restores proper stopping action so doors or internal mechanisms operate more smoothly and safely. What it does:

• Keeps doors, lids or internal linkages from swinging past their intended position.
• Replace if the lug is cracked, worn, broken, missing, or if the mechanism fails to stop or rattles.
• Helps prevent further damage from metal-on-metal contact or excessive movement.

• Disconnect power before starting any repair.
• Basic hand tools and access panel removal may be required to reach the mounting area.
• Inspect adjacent clips, fasteners and mating surfaces; replace any damaged hardware.

This replacement mounting screw secures appliance panels and components to restore proper fit and reduce rattling. Use when a damaged or missing screw causes loose trim, gaps, or vibrating noises; order by part number to ensure a match. What it does:

• Fastens panels, brackets, or trim to keep parts aligned and secure.
• Stops vibration and rattling caused by loose or missing screws.
• Common symptoms: visible gaps, loose panels, hardware falling out, or excess noise.
• Use the part number and/or existing screw to ensure correct size and thread before ordering.

• Disconnect power and water before accessing internal components.
• Use the correct screwdriver or bit to avoid stripping the head.
• Turn until snug; avoid over-tightening which can strip threads or crack trim.
• Keep small parts away from children and pets during repair.

Screw: 8-16 x 3/8 inch.

Tension spring that restores proper movement and positioning for a mechanical assembly in select Whirlpool appliances. Replacing a worn or broken spring helps stop sagging, rattling, or parts that fail to return to their normal position. What it does:

• Supplies tension or counterbalance for a moving component so parts operate smoothly.
• Helps keep doors, lids or levers aligned and from sagging or drifting out of position.
• Reduces excessive vibration or rattling caused by a weakened spring.
• Common symptom linkage: noisy operation, parts that won't stay closed/open, or visibly stretched/broken spring.

• Spring

• Disconnect power to the appliance before beginning any repair.
• Springs can be under tension—wear eye protection and gloves and use proper tools.
• Follow the appliance service manual for correct removal and reinstallation procedures.

This replacement water inlet valve controls the flow of water to the appliance's dispenser and ice-making components, restoring normal fill and preventing supply interruptions when a valve fails. What it does

• Opens and closes to allow water into the dispenser and ice maker on demand

This plate-clutch transfers torque from the washer transmission to the tub so the machine can engage and maintain spin cycles. Replacing a worn plate-clutch helps restore reliable spin performance and reduce slipping or shuddering. What it does:

• Engages the transmission to allow the tub/agitation assembly to spin.
• Helps transfer rotational force for normal spin speeds and load control.
• Commonly replaced when the washer slips out of spin, spins slowly, or shudders during the spin cycle.
• Supports proper clutch engagement to prevent intermittent spin failures.

• Disconnect power and water before beginning any repair.
• Access typically requires removing the washer cabinet and/or agitator; basic hand tools are usually sufficient.
• Inspect surrounding components (drive belt, transmission, clutch housing) for wear while replacing this part.

This replacement water level switch senses tub water height and tells the washer control when to stop filling. It restores accurate fill signaling so cycles can run normally and helps prevent overfilling or incorrect water levels. What it does:

• Detects water level via the pressure/air tube and signals the control board when the correct fill is reached.
• Ensures appropriate water levels for selected cycles so wash performance and cycle progression remain consistent.
• Common symptoms it may cause include overfilling, underfilling, continuous filling, or the washer not advancing through cycles.
• Replaces a faulty or intermittent pressure switch that causes inconsistent fill behavior.

• Disconnect power to the appliance before servicing to avoid shock or injury.
• Installation typically requires removing access panels, unplugging the wiring harness, and detaching the pressure hose from the switch.
