This float palnut is a push-on retainer that secures the dishwasher's water-level float to its stem. Keeping the float anchored helps the overfill protection work properly, supporting correct fill levels and helping prevent leaks from overfilling. What it does:

• Holds the float in position so it can move freely with water level changes
• Helps the float reliably actuate the overfill/float switch
• Replace if cracked, loose, or missing
• Typical symptoms include a loose or wobbly float, the float popping off, erratic filling, overfilling, or leaks near the float area

• One float palnut

• Disconnect power and turn off water supply before servicing
• Remove the lower rack to access the float assembly
• Remove the old retainer; press the new palnut squarely onto the float stem until snug
• The float moves freely up and down before reassembling

This top spray arm, also called the top wash spinner, restores proper water distribution to the top of the tub. It helps deliver even spray coverage so glasses and dishes on the upper rack come out clean. What it does:

• Rotates under water pressure to spray jets across the upper rack area
• Improves wash coverage and rinsing for items on the top level
• Common failure signs: poor cleaning on the top rack, arm not spinning, clogged jets, or visible cracks/warping
• May also cause uneven spray patterns or debris buildup if the spinner is damaged

• 1 top spray arm

• Disconnect power at the breaker and turn off the water supply before servicing
• Open the door; remove the upper rack if needed for access
• Release the retainer or screw, remove the old spinner, and clear any debris from the hub/feed area
• Install the new spinner and ensure it spins freely before running a test cycle

This is the shorter of the two dispenser lid hinge pins. For the longer lid hinge pin order WP6-912678.

Long tub insulation that fits the appliance's inner tub, reducing operating noise and helping stabilize temperature around the tub for quieter, more consistent performance. Replaces worn or damaged insulation to address rattles and drafts. What it does:

• Dampens noise and vibration when insulation is torn, compressed or missing.
• Helps limit heat loss and reduce cold spots that can cause condensation or longer warm-up times.
• Reduces rattling or knocking caused by loose or degraded insulation.
• Intended for specific Whirlpool tubs—verify model fit before ordering.

• Disconnect power (and water supply for washers) before starting any repair.
• Remove outer panels or drum components per the service manual; insulation may be held with clips, adhesive, or fasteners.
• Wear gloves and a dust mask—insulation fibers can irritate skin and lungs.

This power cord strain relief secures the cord where it passes through the appliance cabinet, protecting the jacket and preventing pull on internal connections. Replacing a cracked or missing connector restores a safe, stable cord entry. What it does:

• Secures the power cord at the cabinet entry to relieve strain on internal terminals or junction connections
• Provides a protective bushing to reduce abrasion of the cord jacket against cabinet edges
• Helps maintain proper routing and support for the incoming power cord
• Typical signs it's needed: loose or wobbly cord at entry, broken/missing connector, or visible chafing on the cord jacket

• 1 strain relief connector

• Disconnect power at the breaker or unplug the appliance before servicing
• Remove the access cover, release and remove the old strain relief, and route the cord through the new connector
• Seat the connector fully so it captures the cord's outer jacket—not the individual conductors
• After reassembly, verify the cord is secure and does not move at the entry point

This spray arm retaining nut secures the dishwasher spray arm to its hub, keeping it aligned and spinning for consistent wash coverage. Replacing a worn or stripped nut restores spray performance and helps prevent the arm from detaching during cycles.

• Secures the spray arm to the hub/pump outlet so it rotates freely
• Helps maintain proper alignment and clearance to avoid rubbing or leaks
• Direct replacement for a cracked, loose, or stripped spray arm nut
• Common symptoms: poor cleaning, rattling noises, or the spray arm falling off

• Disconnect power and water supply; remove the lower rack for access
• Unscrew the old nut and lift off the spray arm; clean any debris on the hub
• Position the arm and thread the new nut by hand until snug; do not overtighten
• Spin the arm by hand to confirm free movement before running a test cycle

To order indicator lens use WP22001948.

This rack stop clips onto the end of a dishwasher rack rail to keep the rack from sliding off the track. Replacing a worn or missing stop helps the rack glide securely and prevents accidental pull-outs during use.

• Prevents the rack from being pulled out too far and falling off the rail
• Helps restore smooth, secure rack operation
• Common fix for racks that slide out too far or feel unstable

• Disconnect power and turn off water before servicing
• Pull the rack forward, depress the old stop's locking tab, and remove
• Align and snap the new stop onto the rail end until it locks
• Check rack travel to ensure the stop is fully engaged

This small rubber grommet seals the opening around the dishwasher's detergent/rinse-aid dispenser, helping prevent leaks and moisture intrusion so the dispenser operates reliably throughout the wash cycle.

• Seals the dispenser passage to keep water from leaking into or out of the dispenser cavity
• Helps ensure proper detergent or rinse-aid dispensing
• Can reduce moisture-related corrosion or staining in the dispenser area

• Disconnect power and turn off water before servicing
• Remove inner door panel to access the dispenser assembly
• Note grommet orientation; seat fully to ensure a watertight seal
• Inspect surrounding surfaces for debris or damage before reassembly

The Tub Wheel supports and guides the washer's tub assembly on its base during wash and spin cycles. Replacing a worn wheel restores smoother, quieter operation and helps reduce vibration and rubbing as the machine operates.

• Provides rolling support so the tub can move and self-balance during cycles
• Reduces friction between the tub and the base/frame
• Helps keep the tub centered to minimize noise and vibration
• Failure symptoms include squeaking or grinding, scraping noises, dragging movement, or visible flat spots/cracks on the wheel

• Disconnect power and water supply before servicing; wear appropriate gloves and eye protection
• Access the base/suspension per the service information and support the tub to remove load from the wheel
• Remove the retainer/axle, install the new wheel, and free rotation and correct orientation
• Reassemble, level the appliance, and run a spin test to check for noise and balance

Screw: 8-16 x 3/8 inch.

This replacement screw secures appliance panels, brackets, and components. Using the correct size restores a snug fit to reduce vibration, prevent loosening, and keep assemblies properly aligned during operation. What it does:

• Fastens sheet metal and component brackets in designated locations
• Replaces missing, stripped, or corroded hardware
• Helps eliminate rattling and vibration from loose panels
• Maintains proper alignment of covers and assemblies

• 1 screw

• Disconnect electrical power; shut off water or gas supplies if applicable
• Match length/thread to the original; replace one fastener at a time to preserve alignment
• Start by hand to avoid cross-threading; use the correct driver size
• Snug firmly but do not overtighten to prevent stripping
