• Adds mass to the washer frame/drum assembly so the tub stays balanced during spin
• Helps prevent excessive vibration, banging, and movement during high-speed spins
• Reduces noise caused by an unbalanced load or damaged weight
• Supports proper drum alignment to avoid premature wear on bearings and suspension parts

• One balance weight

• Always unplug the washer before starting any repair to avoid electrical shock
• Support the drum/tub when removing or installing the weight to prevent component damage
• Reuse or replace any mounting hardware only if explicitly specified by the manufacturer
• If vibration persists after replacement, inspect suspension, shock absorbers, and mounting points

Plastic cover that fits over the washer tub assembly. Protects internal components and provides structural support. Replace if cracked, damaged, or missing.

This is a replacement screw used to secure internal components and assemblies. It restores proper fastening when original screws are stripped, loose, or missing. What it does

• Secures panels, brackets, or small assemblies to prevent rattling and misalignment
• Restores proper fit when original fasteners are worn, stripped, or lost
• Helps stop vibration-related noise from loose parts
• Matches OEM fastening locations and thread style for intended application

• Screw as shown

• Unplug the appliance or disconnect power before starting any repair
• Use the correct screwdriver or driver bit to avoid stripping the head
• Tighten until snug; avoid overtightening which can strip threads or crack plastic
• Keep small parts away from children and dispose of damaged fasteners

This rotor position sensor (Hall sensor) tracks the direct-drive motor's rotor position and speed so the control can commutate the washer motor accurately. Replacing a failed sensor can restore proper wash/agitate and spin performance. What it does:

• Detects rotor position and speed from the stator assembly
• Sends timing feedback to the control for correct motor start, direction, and speed
• Supports smooth agitation and spin ramp-up/ramp-down
• Failure may cause: no spin or agitation, cycle stalling/pausing, or an LE motor error code

• 1 rotor position sensor assembly

• Unplug the washer and shut off water; wear protective gloves
• Access the motor at the rear of the tub; remove the back panel if needed
• Remove the rotor and stator; support the stator to protect wiring, then unclip/unscrew and replace the sensor
• Align the sensor correctly and seat the connector fully before reassembly and testing

This rotor assembly is the rotating half of your washer's direct-drive motor. It mounts to the rear of the tub and, working with the stator, spins the drum for wash and spin cycles to restore smooth operation.

• Couples with the stator to drive the inner tub during wash and spin
• Helps resolve no- or slow-spin complaints
• Can address a drum that won't turn or turns intermittently
• May reduce grinding/clicking from the rear caused by damaged rotor magnets

• Unplug the washer and turn off water supply before servicing
• Access from the rear; remove the center bolt and pull the rotor straight off the shaft
• Magnets are strong—keep fingers clear; align splines/keyway on reinstallation
• Tighten the center bolt securely and inspect the stator and sensor while open

This hinge spring restores proper tension to the door so it opens and closes smoothly and stays aligned. Replacing a fatigued spring helps prevent sagging or slamming and supports a consistent, reliable door close.

• Provides the return tension/counterbalance for the door hinge mechanism
• Assists smooth opening/closing and helps the door stay properly aligned when latched
• Helps maintain consistent closing force over time
• Failure symptoms include: door drops quickly, won't stay aligned or fully closed, weak/squeaking spring action

• Disconnect power before service; allow any hot surfaces to cool
• The hinge and spring are under tension—support the door and release/install tension carefully
• Note spring orientation and hole positions before removal; match them on installation
• Access may require removing trim or the door; keep fasteners organized for reassembly
