This cover screw secures an appliance cover or access panel to the cabinet, protecting internal components and reducing vibration. Replace missing, stripped, or corroded screws to keep panels tight and the unit safe and quiet.

• Fastens a cover or access panel to the appliance chassis
• Maintains proper panel alignment and enclosure integrity
• Helps eliminate rattles or buzzing from loose panels
• Typical symptoms: loose/misaligned cover, missing screw, vibration noise

• Disconnect power; for gas/water appliances, shut off supplies before service
• Wear cut-resistant gloves—sheet-metal edges can be sharp
• Align the cover and start the screw by hand to avoid cross-threading
• Tighten snugly; do not overtighten into plastic or thin metal

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.

Includes two screws, two clamps, and undercounter mounting brackets.

Located between the console and door

Lower wash arm redirects pressurized water across the dishwasher's lower rack to rinse and remove food and residue, restoring intended wash coverage and improving cleaning performance. What it does:

• Directs jets of water through multiple spray holes to rinse dishes on the lower rack.
• Helps remove stuck-on food, film and spotting on plates, bowls and cookware.
• Replaces cracked, clogged or broken lower spray arms that can cause poor cleaning or leftover residue.
• Works with the dishwasher's pump flow to maintain proper spray pattern across the lower rack.

• Refer to your model's parts diagram and instructions; the arm commonly snaps or threads onto the lower spray arm mount and procedures vary by model.
• Always disconnect power to the dishwasher before servicing; follow basic safety precautions.
• Clean the filter and any debris from spray holes before installing to avoid re-clogging.
• Inspect the mounting clip or retaining nut when removing the old arm and replace if damaged.

This active vent assembly controls airflow from the dishwasher during and after a cycle, releasing humid air at the right time for better drying. Replacing a faulty vent can reduce lingering moisture and steam escaping from the door.

• Regulates and directs moist air out of the tub during the dry portion of the cycle
• Closes during wash to help contain water and heat inside the dishwasher
• Helps reduce interior condensation and improve overall drying results
• Common failure symptoms: dishes not drying, moisture remaining after the cycle, steam escaping at the top of the door, or unusual noise from the vent area

• Disconnect power at the breaker before servicing; allow the unit to cool
• Access is typically through the inner door panel; retain and reuse mounting hardware as required
• Inspect and correctly seat the vent seal to prevent steam leaks
• After installation, run a test cycle to check for proper vent operation and sealing

Replacement fill hose that routes water from the household supply to the appliance's ice maker and water dispenser, restoring proper water delivery and helping prevent leaks or pooling from a damaged line. What it does

• Directs water from the inlet valve to the ice maker and dispenser for ice production and dispensing.
• Maintains steady water flow; prevents kinks and pinched lines that reduce flow.
• Replace if cracked, split, collapsed, or leaking.
• Common symptoms: reduced or no water to the dispenser or ice maker, visible leaks, or pooling under/behind the appliance.

• Turn off the water supply and disconnect power before servicing to avoid flooding and electrical hazard.
• Inspect and replace clamps or fittings as needed; ensure proper seating and a snug, leak-free connection without overtightening.
• Check for kinks in the hose and route it so it won't be pinched by the appliance or cabinetry.
• After installation, turn the water back on and test for leaks at all connections.

This foam pad installs between the inner and outer door panels of a dishwasher to dampen sound and help shield the outer panel from heat and moisture, keeping operation quieter and the door better protected. What it does:

• Lines the inside of the outer door panel to reduce operating noise and vibration
• Acts as a thermal and moisture barrier for the outer door panel
• Helps maintain proper door performance when the original insulation is worn or missing
• Replace if torn, degraded, or waterlogged, or if noise/condensation around the door has increased

• 1 door insulation pad

• Disconnect power and shut off water to the dishwasher before servicing
• Support the door; remove perimeter screws to separate the inner and outer door panels
• Note the pad's orientation; seat the new insulation evenly without pinching wires or harnesses
• Reassemble panels and fasteners; verify smooth door/latch operation

This silverware basket organizes utensils in the lower rack of your dishwasher so water can reach them evenly. Replacing a cracked or missing basket keeps small items contained and helps prevent interference with the spray arm.

• Holds cutlery and small utensils upright during wash and rinse cycles
• Keeps small items from falling through the rack or onto the heater
• Replace if the basket is cracked, warped, melted, or missing sections
• May help with utensils tipping over, rattling, or blocking the spray arm

• Remove the lower rack, lift out the old basket, and position the new basket in the same location
• Ensure the basket does not obstruct the spray arm and the rack rolls freely
• Handle sharp utensil tips carefully; install with the dishwasher cool and empty

This dishwasher overfill control float mounts in the tub floor and rises with the water level to trip the float switch and stop filling. Replacing a warped or stuck float restores proper fill control and helps prevent leaks. What it does:

• Monitors tub water level and actuates the float switch to shut off the inlet valve
• Helps prevent overfilling and water leaking from the door
• Common symptoms of a faulty float include no fill, continuous filling/overfilling, or inconsistent water level

• Float and retainer

• Disconnect power and turn off the water supply before servicing
• Remove the lower rack; lift out the old float
• Access beneath the tub may be required to release/install the retainer
• Ensure the float stem engages the switch lever and moves freely; test-fill and check for leaks

This dishwasher door strike mounts to the tub opening and provides the catch point for the door latch. Replacing a worn or bent strike restores positive latching so the control can sense a closed door and run cycles reliably.

• Provides the catch the door latch locks onto
• Engages the door switch so the dishwasher can start
• Helps keep the door securely closed during operation
• Common symptoms: door won't latch or pops open; unit won't start unless pressure is applied to the door; strike is visibly bent, worn, or missing

• Disconnect power at the breaker; turn off water if you need to move the appliance
• Open the door to access the strike at the tub opening; remove mounting screws, replace the strike, and tighten securely
• Save and reuse the original mounting screws
• After installation, check latch engagement and adjust appliance leveling or alignment if needed

This upper rack wheel and axle assembly lets your dishwasher's top rack glide smoothly and stay level. Replace a cracked or missing wheel to fix hard-to-slide racks, scraping noises, or a rack that slips off the rail.

• Provides rolling support for the upper rack along the rails
• Helps keep the rack aligned to prevent sagging or derailment
• Replaces worn, cracked, or seized wheel assemblies
• Common symptoms: rack hard to slide, wheel wobbles/missing, grinding or scraping sounds, rack coming off track
