This dishwasher water deflector redirects spray back into the tub at the front edge, helping prevent splash-over and leaks during cycles. Replace a cracked, warped, or missing deflector to keep floors dry and wash performance consistent.

• Directs wash water away from the door opening and front corners
• Helps reduce leaks and puddles at the bottom front of the dishwasher
• Restores proper containment when the original deflector is deformed, loose, or missing
• Common symptoms include water on the floor at the front, drips during cycles, or visible damage to the deflector

• Disconnect power and turn off the water supply before servicing
• Open the door to access the front/tub area; remove the old deflector
• Clean the mating area and seat the new deflector fully and evenly
• Run a short test cycle and check for leaks

This wax motor is the actuator for the dishwasher's rinse aid dispenser, releasing rinse agent at the correct time in the cycle. Replacing a weak or failed unit restores consistent rinse aid dispensing and helps minimize spotting.

• Actuates the rinse aid dispenser by extending a plunger when energized
• Works with the control to meter rinse aid during the final rinse
• Failure symptoms can include rinse aid not dispensing, the level never dropping, and increased spotting/filming on dishes
• Dispenser may remain closed with no audible actuation during the cycle

• Disconnect power at the breaker and shut off water before servicing
• Remove the door panel to access the dispenser; label and disconnect wires
• Release the old motor and install the new one in the same orientation, ensuring it seats fully
• Run a test cycle to ensure the dispenser releases rinse aid

Dishwasher rack mounting strip roller.

This hose clamp secures a hose connection to prevent leaks and keep your appliance running smoothly. It provides a tight, reliable hold on the hose fitting so water or air stays contained during operation.

• Tightens around a hose and fitting to maintain a secure seal
• Helps stop drips, seepage, or loose connections
• Common fix when you see moisture around a hose joint
• Useful if a clamp is rusted, stretched, or no longer holding tension

• Unplug power and shut off water (if applicable) before servicing
• Note clamp position/orientation before removal
• Use appropriate screwdriver or nut driver to tighten evenly
• Do not overtighten—ensure a snug, leak-free seal without damaging the hose

This replacement door handle restores a secure grip and normal door operation on compatible Whirlpool appliances. It provides a like-for-like fit and finish to replace a damaged, loose, or worn handle so doors open and close reliably. What it does:

• Replaces a broken, cracked, or missing door handle to restore normal use
• Provides a solid grip so the door opens and closes smoothly
• Matches the original mounting points for straightforward fit
• Helps eliminate rattling or loose-handle symptoms

• Turn off and unplug the appliance or shut off power at the breaker before servicing electrical appliances
• Use moderate force when aligning the handle to avoid damaging trim or fasteners

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 dishwasher impeller assembly mounts on the circulation pump and pressurizes wash water for the spray arms. Replacing a worn or damaged impeller restores proper spray pressure, cleaning performance, and quieter operation.

• Spins with the circulation motor to pressurize wash water
• Drives flow to the spray arms for effective wash action
• Typical symptoms: weak or no spray, poor cleaning results, grinding or rattling from pump area
• Often fails from broken vanes or debris; inspect filters/chopper while open

• Disconnect power and water before servicing
• Access is typically from inside the tub: remove the lower spray arm, filter screens, and cover to reach the impeller
• Note the order of parts and transfer any reusable hardware; replace worn O-rings/seals as needed
• Do not overtighten plastic parts; verify the impeller spins freely before reassembly and testing

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

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 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
