This dishwasher door seal fits into the tub channel to create a tight, water-resistant barrier when the door closes. Replacing a worn gasket helps stop nuisance leaks and restores proper door compression and moisture containment.

• Creates the primary seal around the dishwasher tub opening when the door is closed
• Helps keep wash water, suds, and steam inside the wash cavity
• Wear can lead to drips at the front corners or along the sides
• Replace if the gasket is cracked, torn, flattened, or no longer sealing; the door may be harder to latch

• Disconnect power and turn off the water supply before servicing
• Remove the old gasket and thoroughly clean the channel of debris and residue
• Warm and relax the new gasket; start at the top center and press evenly into the channel without stretching
• Close the door for several hours to help the seal set; run a test cycle and check for leaks

This compression tube nut secures water inlet tubing to a threaded fitting to create a reliable, leak-resistant seal. Replace a cracked or stripped nut to stop drips at the connection and keep your appliance's water system working properly.

• Compresses the tubing against the fitting to seal the water line at the inlet valve, filter head, or other water-system connections
• Helps correct leaks at the water line connection point
• Replaces nuts that are cracked, cross-threaded, or deformed
• Common symptoms: water dripping at the connection, difficulty tightening the line, or a poor seal after reassembly

• Shut off the water supply and disconnect power before servicing.
• Slide the nut onto the tubing first, seat the tube fully on the fitting, then hand-tighten and snug with a wrench; do not overtighten.
• Inspect and reuse the existing sleeve/ferrule and tube insert if in good condition; replace if worn.
• Restore water and check for leaks at the connection.

The door balance mount is the side-frame bracket that supports the dishwasher's door counterbalance system. When worn or broken, it can let the door drop, slam, bind, or feel heavy. Replacing it restores smooth, controlled door movement. What it does

• Anchors the door springs and balance link/cable to counterbalance the door's weight
• Helps the door open and close smoothly without dropping or slamming
• Guides the balance link for consistent, quiet movement
• Common symptoms: door feels heavy or uneven, falls open, won't stay put, or makes grinding/squeaking noises; visible damage to the bracket or rollers

• One door balance mount (bracket)

• Disconnect power and shut off water before servicing
• Pull the dishwasher out slightly to access the side where the mount is installed
• Carefully relieve spring tension; note link/cable routing before removal
• Transfer the spring/link to the new mount, secure the bracket, and check door balance on both sides

Right Side. For left side use part number WPW10251050.

This electronic control board kit is the appliance's central controller, coordinating inputs and powering key components. Replacing a failed board restores proper operation, responsive controls, and reliable cycle management. What it does:

• Manages timing and power to motors, valves, heaters, fans, and other loads
• Interprets sensor and user-interface signals to start, run, and end cycles correctly
• Common failure signs: dead or unresponsive controls, cycles that won't start/finish, repeated error codes, or intermittent operation
• Helps address issues caused by power surges or board damage

• 1 electronic control board (module)

• Disconnect electrical power to the appliance; turn off gas/water if applicable
• Use ESD protection and handle the board by its edges
• Photograph wiring; transfer connectors one at a time and match any jumpers/DIP-switch settings from the original board
• Restore power and perform any model-specific tests or programming per OEM instructions

This inner door seal forms a moisture barrier between the dishwasher tub and the door assembly, helping keep wash water and steam contained. Replacing a worn seal can stop drips at the door and protect internal components.

• Seals the joint along the inner door to contain wash water and steam
• Helps prevent door-area leaks or drips during cycles
• Blocks moisture from entering the door cavity where electrical parts reside
• Common signs: water at the bottom/sides of the door, damp control area, visible wear/flattening or tears on the seal

• Disconnect power and turn off water supply before servicing
• Open the door and remove perimeter screws to separate inner/outer door panels
• Remove the old seal; clean the mounting surface and note seal orientation
• Press the new seal firmly into place, reassemble, and run a leak check

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.
