Mdb-3 Parts

Replacement 8-32-thread screw used to secure panels, brackets and small components in compatible household appliances. Restores missing or stripped fasteners so panels and parts stay firmly attached during normal use. What it does:

• Secures trim, panels, brackets and control housings to maintain proper assembly.
• Replaces missing or damaged screws that can cause rattling, loose panels or misaligned components.
• Fits locations that require an 8-32 threaded fastener; correct length and head style for your application.
• Helps restore stable, vibration-free operation when worn or stripped fasteners are replaced.

• Disconnect power and water before servicing; wear eye protection and gloves.
• Use the correct screwdriver or driver bit to avoid stripping the screw head.
• Do not overtighten—turn until snug and secure to avoid damaging threads or surrounding parts.
• If the original used a washer or nut, reuse or replace as needed and the screw length and head type match the original.

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:

• Allow the dishwasher interior to cool
• Open the door, remove the lower rack, and snap the protector into place per the tower/rack design
• Verify it seats securely and does not interfere with the spray tower movement

This replacement cam converts rotational motion into the precise movement needed by the appliance's linkage or latch assembly, restoring proper mechanical timing and part engagement. Use this cam to replace a worn, broken, or stripped cam and help return reliable operation. What it does

• Transfers motor or shaft rotation into controlled push/pull motion for linkages or latches
• Restores correct timing and movement when a plastic cam is cracked, worn, or slipping
• Helps resolve symptoms like intermittent or failed door/latch action, noisy operation, or improper cycle sequencing
• Works as a like-for-like mechanical replacement when the OEM cam has failed

• One replacement cam (single piece only)

• Disconnect power (and water supply if applicable) before beginning any repair
• Inspect mating shafts, linkages, and fasteners; replace any damaged hardware to prevent repeat failure

Specs: No.8X1/2 HEX WASHER HEAD

This wet agent dispenser replaces the washer's liquid fabric softener dispenser to restore proper dispensing during the rinse cycle. It helps keep softener contained until the machine is ready to release it, improving rinse-time performance. What it does:

• Holds and releases liquid fabric softener (wet agent) into the rinse cycle
• Ensures softener is delivered at the correct time for even distribution
• Stops leaking or premature release when the dispenser housing is intact
• Commonly replaced when the dispenser cracks, clogs, or fails to dispense

• Disconnect power to the appliance before starting any repairs
• Access method varies by model; remove dispenser drawer or top panel per your model's service instructions
• Inspect surrounding seals and clips; replace if damaged to prevent leaks

This grate captures heavy soils and debris at the bottom of the washer tub to help reduce re-deposition on clothing and keep the drain area clearer. Restores proper soil separation for more consistent wash results. What it does:

• Traps heavy dirt and debris so it doesn't recirculate onto clothes during the wash.
• Helps keep the drain/under-tub area clearer, reducing the chance of clogs.
• Supports proper water flow and soil separation for improved cleaning performance.
• Common symptoms indicating a failing or missing part: clothes still look soiled after a cycle, visible debris in the tub, or frequent drain blockages.

• One grate

• Disconnect power and shut off water before servicing the washer.
• Drain the tub and remove any agitator or tub components required for access.
• Use basic hand tools; avoid forcing parts or over-tightening plastic components.

Seal head assembly replaces the seal around the dishwasher pump motor shaft to stop leaks and protect the motor. It restores a watertight seal so the dishwasher drains safely and avoids cabinet water damage. What it does:

• Seals the pump motor shaft to prevent water from leaking into the motor and cabinet.
• Helps stop under-dishwasher puddling, external leaks, and moisture-related motor issues when the original seal fails.
• Restores proper drainage path by maintaining the seal between the pump and housing.
• Compatible with service procedures that replace the pump seal as directed by OEM diagrams.

• Disconnect power and turn off the water supply before servicing.
• Drain the dishwasher and remove access panels to reach the pump; handle the seal carefully to avoid damage.
• Inspect surrounding gaskets and pump housing for wear; replace any damaged components to ensure a proper seal.
• After installation, run a short cycle and check thoroughly for leaks before returning the dishwasher to regular use.

Color: Gray

Float that detects and communicates water level to the appliance control so the washer or dishwasher can fill and drain properly. Replaces a cracked, stuck, or worn float to restore reliable water sensing. What it does:

• Senses water level and relays position to the machine's control system.
• Helps prevent overfilling or unintended continuous filling when working correctly.
• Can resolve symptoms such as flooding, constant filling, no fill, or improper drain cycles.
• Works with the appliance's existing valve and switch components to re-establish normal fill/drain operation.

• Disconnect power (and water supply where applicable) before beginning service.
• Remove outer panels or tub shroud to access the float; use basic hand tools.
• Handle clips and fittings gently; do not force plastic tabs or connectors during removal/installation.
• After installation, restore power and run a test cycle to ensure correct fill and drain behavior.

The Lower Washarm is an OEM replacement part for Whirlpool dishwashers. Positioned at the bottom of the dishwasher tub, it rotates during the wash cycle, distributing water and detergent evenly across the lower rack. 

Over time, wash arms can become clogged with food debris or mineral deposits, reducing water flow. Physical damage such as cracks or warping can also impede the wash arm's rotation and affect its cleaning performance.

Color: Gray

Symptoms of a faulty lower wash arm include:

• Inadequate cleaning of dishes on the lower rack
• Uneven or inconsistent water spray
• Clogged or obstructed spray nozzles
• The arm not spinning or rotating correctly

This OEM Whirlpool part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.

This switch holder secures a small appliance switch or actuator in the correct position so the control can detect and respond reliably. Replacing a cracked or broken holder restores consistent switch alignment and helps prevent intermittent operation. What it does:

• Holds the switch or actuator steady in the correct position for reliable electrical contact and activation
• Keeps the switch aligned so buttons, door/lid actions, or control functions register properly
• Common symptom: appliance function won't engage or is intermittent when the switch is loose or the holder is damaged
• Prevents further wear on the switch by keeping it from shifting or rubbing against surrounding parts

• Disconnect power (unplug or shut off breaker) before servicing the appliance
• Remove the control panel or access panel to reach the holder; keep small clips and screws organized
• Inspect the switch and actuator for damage while replacing the holder; replace any damaged mating parts

This tub wheel mounts on the dishwasher's tub wall to guide and support the rack as it slides in and out. Replacing a worn wheel restores smooth rack movement and helps prevent binding, noise, and derailments.

• Mounts to the tub to provide rolling support for the dish rack/rail
• Replaces cracked, flattened, or missing wheels that impede rack travel
• Helps fix racks that stick, bind, are hard to pull/push, or derail
• Reduces grinding or squeaking from the rack area

• Disconnect power at the breaker before servicing
• Open the door and pull the rack forward for access
• Release the old wheel from its retainer/axle per your model's design; install the new wheel in the same orientation
• Ensure the wheel spins freely and the rack slides smoothly before use
