Color: Black. Dishwasher door latch handle. For the latch order WP99002292.

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 thermostat retainer is the mounting clip that keeps the dishwasher's thermostat secured to its base or bracket. Proper retention helps maintain accurate temperature sensing and consistent heater safety through the wash and dry portions of the cycle. What it does:

• Holds the thermostat firmly in place on the base or mounting bracket
• Prevents the thermostat from shifting, vibrating loose, or falling out of position
• Supports accurate temperature sensing and overheat protection
• Common signs of a bad/missing retainer: broken or warped clip, thermostat hanging loose, intermittent heat/drying performance

• 1 thermostat retainer

• Disconnect power and shut off water before servicing
• Remove the lower access/toe-kick panel to reach the thermostat area
• Note the thermostat's orientation; transfer it to the new retainer and snap/secure the retainer to the existing mount/hardware
• Ensure the thermostat is fully seated and wiring is routed clear of sharp edges and hot/moving components

Bottle with brush. Color: Biscuit paint. It's point-six fluid ounces.

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.

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.

Color: light blue. This tine latch measures about an inch wide.

This impeller assembly replaces a worn or damaged wash-pump impeller to help restore water circulation and spray pressure for better cleaning. Commonly used in compatible Whirlpool wash pumps to address weak wash performance. What it does:

• Spins inside the wash pump to move water through spray arms; damaged fins reduce spray force and cleaning.
• Restores proper flow during wash cycles — symptoms of failure include weak or uneven cleaning.
• Reduces abnormal pump noise and motor strain when the impeller is intact; cracked or missing fins can cause humming or grinding.
• Works with the pump housing and seals to route water; a failed impeller can allow internal leakage or cavitation.

• Always disconnect power (and water, if applicable) before servicing the appliance.
• Inspect pump seals, gaskets, and surrounding components; replace any damaged parts to prevent leaks.

To order indicator lens use WP22001948.

This door switch detects when the dishwasher door is fully closed and latched. Replacing a worn or intermittent switch restores reliable start/stop operation and ensures the safety interlock cuts power whenever the door is opened.

• Senses door-closed status and sends a signal to the control
• Interrupts power to the machine when the door opens
• Helps prevent operation with an unlatched door
• Typical failure symptoms: won't start, stops mid-cycle if the door is bumped, or only runs when pressing on the door

• Disconnect power at the breaker before servicing
• Access the latch/switch area by removing the inner door panel or console; note wire locations
• Transfer wires one at a time and secure the new switch in the bracket
• Verify latch engagement and switch actuation before restoring power

Dishwasher rack rear bowl tine. For the front tine order 12002218. For the tine clip order WPY912709.

• 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

• 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
