This electronic board regulates power and speed to the washer's drive motor, working with the main control to coordinate agitation and spin. Replacing a failed motor control unit restores consistent drum movement and resolves no-spin or no-agitate issues. What it does:

• Governs motor start, direction, and variable speed during wash and spin
• Common failure symptoms: won't spin or agitate; starts then stops; intermittent or slow rotation
• Visible burn marks, odor, or damaged components on the board
• Verify power, wiring, and motor condition before condemning the board

• One motor control board

• Disconnect power and turn off water before service; allow components to discharge
• Use ESD precautions and handle the board by its edges
• Access location varies by model; photograph connectors and transfer them one at a time
• Inspect the drive motor, wiring harness, and drive components for shorts before powering up; run diagnostics after installation

Size: 1-1/16 x 5/8 inch. Used for fill hose. For a 4 pack order 285448A

This front counterweight mounts to the washer's outer tub to help balance and stabilize the drum during spin. Replacing a damaged weight can reduce vibration and noise and help prevent the machine from walking. What it does:

• Adds mass at the front of the tub to counterbalance loads during spin
• Helps control vibration, shaking, and banging noises
• Can resolve out-of-balance interruptions or excessive movement
• Visible cracks or broken mounting ears indicate the weight needs replacement

• One front counterweight

• Disconnect power and water; use proper lifting techniques—this part is heavy
• Support the tub and remove front cabinet components/door boot as needed for access
• Remove and retain mounting bolts; tighten bolts evenly when reinstalling
• Inspect mounting points and suspension components while accessible; replace if worn

This replacement ball is the small spherical component used in select Whirlpool-built mechanisms. It acts as a moving seal or detent to control flow or position, restoring smooth, reliable operation when the original ball is worn or missing. What it does:

• Provides the sealing or detent action within its valve, hinge, or track assembly
• Helps prevent backflow, leaks, or unwanted movement
• Restores smooth operation when mechanisms feel rough, bind, or won't stay in position
• Replace if the original is deformed, pitted, corroded, or missing

• 1 ball

• Disconnect power and shut off water supply if applicable
• Access the specific assembly per your model's service documentation and note part order
• Place the ball in its seat/track with any companion spring or seal as designed
• Inspect mating surfaces and related seals or springs and replace if worn

This dishwasher door latch lever links the handle to the latch and safety switches so the door can secure closed and the cycle can start. Replacing a cracked or worn lever restores reliable latching and starts. What it does:

• Transfers handle movement to the latch mechanism and door switches
• Helps the control recognize a fully closed door so the dishwasher will run
• Contributes to keeping the door securely closed during operation
• Resolves: cycle won't start, door won't latch or stay closed, need to hold door to run, loose/floppy handle feel

• 1 lever

• Disconnect power at the breaker before servicing the door
• Open the door and remove inner door panel screws to access the latch/handle area
• Note the original lever's orientation; move any springs/clips to the new lever and seat it fully in the pivot
• Reassemble, verify smooth handle action, and ensure the door latches and a cycle initiates

This water level pressure switch senses air pressure from the tub and signals the control when the correct level is reached. Replacing a failed switch restores proper filling and helps the washer advance through each cycle reliably.

• Monitors tub water level via the pressure (air) hose and sends the signal to stop filling
• Helps prevent overfilling or underfilling so cycles can start and complete properly
• Common symptoms of a failed switch: keeps filling or won't fill, stuck on sensing, won't advance to wash or spin, or drains immediately after filling
• Also called a water level sensor or pressure sensor in some documentation

• Disconnect power and turn off water supply before servicing
• Access the switch near the control/console area; note hose routing and connector position
• Transfer the pressure hose and electrical connector to the new switch; inspect the hose for kinks, cracks, or blockages and ensure an airtight fit
• Restore power and run a quick fill/test cycle to verify normal operation

This RFI noise filter conditions the AC power entering your microwave, reducing electrical interference and helping protect and stabilize the control and power circuits. Replace it if the unit is dead or trips a breaker when starting.

• Filters radio-frequency/electromagnetic noise on the incoming AC line
• Helps stabilize power to the control, relays, lights, and fans
• Failure may cause no display or intermittent loss of power
• A shorted filter may blow the line fuse or trip the household breaker when plugged in or when Start is pressed

• Disconnect power by unplugging the microwave or switching off the dedicated circuit breaker
• For over-the-range units, remove the microwave from the wall to safely access internal components
• Label and transfer wires to matching terminals; mount the filter securely and route wiring away from sharp edges

This Marquardt ground switch completes the appliance's ground connection so controls and safety systems have a proper reference. Replace a failed ground switch to restore reliable grounding and help eliminate related electrical faults. What it does:

• Provides the ground connection path used by controls and safety circuits.
• Replaced when continuity tests fail or when appliances have intermittent power, control errors, or nuisance breaker trips.
• Restores correct electrical grounding to help reduce fault conditions and erratic control behavior.
• Matches the original switch form and electrical connector layout for a direct replacement.

• Disconnect all power (unplug appliance and/or shut off breaker) before beginning service.
• Photograph or label wiring and connector positions before removal; transfer connectors to the new switch exactly.
• Inspect connectors and wiring for damage; replace any frayed or heat-damaged wiring.

Size: 8-18 x 1/2 inch.

This retaining nut secures components within the pump/motor assembly, keeping them tight and properly aligned so your appliance can circulate water reliably. A worn or missing nut can lead to leaks, noise, or poor wash performance.

• Holds pump/motor parts firmly in place to prevent loosening and leaks
• Helps maintain proper water circulation and wash quality
• Direct-fit replacement for the original fastener in applicable units

• Disconnect power and shut off water before servicing
• Access the pump/motor area; note orientation of parts before removal
• Hand-start threads carefully to avoid cross-threading, then tighten to secure
• Inspect related seals and O-rings; replace any damaged components during reassembly

Includes water temperature sensor.

This drawer hook is the retainer that keeps an appliance drawer securely seated while still allowing easy release for cleaning or service. Replacing a worn or broken hook restores smooth, reliable drawer operation.

• Secures the drawer in its housing so it stays closed during use
• Acts as the catch/release point for removing the drawer when needed
• Helps maintain proper alignment for smooth opening and closing
• Common symptoms: drawer won't stay closed, pops open or falls out, won't latch, or the hook is visibly cracked/missing

• Disconnect power before servicing
• Fully open and remove the drawer to access the hook area
• Align the new hook with the slots/tabs and snap or seat it into place
• Avoid forcing components; refer to the service manual for model-specific steps

This 3/8-in gasket creates a tight seal inside a compression-style fitting to help prevent leaks at the connection point. Replace a hardened, cracked, or deformed gasket to restore a reliable, drip-free seal. What it does

• Seats inside a 3/8-in compression fitting to seal the joint
• Helps stop drips and seepage at the supply/inlet connection
• Maintains proper flow by preventing air and water leaks
• Typical symptoms include moisture at the fitting, recurrent need to retighten, or a visibly flattened/damaged gasket

• 1 gasket (3/8-in)
