This PCB assembly is the appliance's main electronic control board. It replaces a damaged or faulty control board to restore programmed cycles and electronic functions for models that use this OEM part number. What it does:

• Controls user interface inputs, cycle selection, and machine operation logic
• Manages power delivery to valves, motors, and sensors through relay and driver circuits
• Detects and responds to sensor signals to coordinate wash/dry/heating sequences
• Can stop or err if the board fails, causing no power, unresponsive controls, or erroneous error codes

• Disconnect power and water before beginning any repair
• Take photos or label wiring before disconnecting harnesses to ensure correct reassembly
• Handle the board by the edges and avoid static discharge; use an anti-static wrist strap if available

This door boot gasket forms the flexible seal between the outer tub and cabinet opening on a front-load washer to keep wash water contained. Replace a torn or moldy boot to stop leaks and lingering odors.

• Creates a watertight seal between the outer tub and the door opening
• Flexes with drum movement to maintain a reliable barrier during wash and spin
• Helps resolve leaks at the door, visible rips or cracks, water on the floor after a cycle, and musty smells that persist after cleaning

• Unplug the washer and turn off water supply before servicing
• Remove the front panel as needed; note the boot's orientation before removal
• Clean mounting grooves; seat the new boot evenly all the way around and secure clamps firmly
• Run a quick cycle to check for leaks after reassembly

The Pump Assembly is an OEM part for LG washing machines. It plays an important role in moving water into and out of the washer tub during operation cycles. 

Causes of pump assembly failure generally stem from normal wear and tear on internal components over time. Mineral buildup from hard water or sediment can also clog critical areas.

Symptoms of a bad pump assembly include:

• Incomplete or slow filling/draining of water 
• Strange noises emanating from within the washer tub
• Error codes related to water level or drainage issues
• Reduced washing or rinsing performance

This LG OEM replacement part is also compatible with some Kenmore models. 

This clamp assembly secures the washer's door boot (gasket) in its groove to maintain a watertight seal at the front of the tub. Replace a stretched, bent, or broken ring to stop leaks and keep the boot properly seated.

• Holds the door boot/gasket firmly to prevent front-panel water leaks
• Restores proper tension when the original ring is deformed or the spring fails
• Common symptoms: water leaking at the front, boot slipping off, visible broken or missing clamp
• Often replaced during door boot service to ensure an even, reliable seal

• Disconnect power and turn off water supply before servicing
• Carefully relieve tension and remove the old clamp without tearing the boot
• Install the new clamp evenly around the opening
• Run a short test cycle and check for leaks after reassembly

This factory bolt assembly is a hardware fastener used to secure designated components within the appliance. Replacing a worn or missing bolt restores a tight, stable connection to help reduce vibration and noise while keeping parts properly aligned. What it does:

• Secures a component to its bracket, frame, or base
• Maintains alignment and stability of the assembly
• Helps minimize vibration and rattling when tightened correctly
• Common symptoms: missing or stripped bolt, loose connection, unusual vibration/noise, visible damage to the bolt head or threads

• Disconnect power and, if applicable, shut off water supply before servicing
• Support the component being fastened to prevent strain while removing/installing the bolt
• Start threads by hand to avoid cross-threading; tighten snugly per OEM guidance—do not overtighten
• Reinstall any washers, sleeves, or grommets in the original order if present

The Stator Assembly is an OEM part for LG washing machines. The stator assembly acts as the stationary component of the motor that drives the wash drum and basket. It converts alternating current into mechanical motion through electromagnetic induction, working together with the rotor to power the motor.

Causes of a bad stator assembly can include defects in the windings, bearing wear, or damage due to excessive heat.

Symptoms of a bad stator assembly include:

• The motor failing to start or run
• Abnormal noises coming from the transmission
• Vibration or shaking issues
• Inability to advance cycles

This OEM LG part is also compatible with some Kenmore models.

The LG Washer Door Hinge Assembly is an OEM component specially designed for LG brand laundry machines. This assembly includes the front-loading door hinges that allow the washer door to securely open and close.

Symptoms of a bad hinge assembly include:

• A door that falls off entirely or does not stay attached 
• Squeaks, squeals, or grinding noises coming from hinges
• Restricted or difficult door-swinging movement
• Detached or failing hinge pins allow the door to sag

Causes of a bad hinge assembly can include wear and tear from years of constant door swinging motions, corrosion buildup interfering with smooth operation, or damage from excessive weight loads improperly handled.

The PCB Assembly, Display is an OEM part specifically designed for LG front-load washers. It controls the washer's user interface including digital readouts, cycle/option buttons, and fault/status displays.

Causes of a bad PCB Assembly, Display would be damaged from water damage when cycling, long-term component degradation, or shocks exceeding durability. Moving parts concentrate stress that electronic paths must withstand. 

Symptoms of a bad PCB Assembly, Display include:

• Unresponsive or "glitchy" controls like stuck buttons  
• Garbled or missing characters on the screen
• Inability to change settings or view cycle status
• Frequent error codes obscuring instructions

Replacing with this genuine LG board resurrects full interactivity for customers. Clear guidance simplifies use while smart notifications maintain machine wellness. This LG part fits Sears/Kenmore washers as well.

The NOISE FILTER ASSEMBLY is an OEM part for LG washing machines. It is a component designed to minimize vibrations and reduce noise emanating from the washer during operation. Proper noise damping is important for smooth functionality without disturbance.

Causes of a bad noise filter assembly can include cracks or tears developing over extended use. Physical damage from impact could also compromise its noise-blocking abilities. 

Symptoms of a bad noise filter assembly include:

• Loud banging or clanking noises during wash and spin cycles
• Excessive vibrations felt through the washer cabinetry 
• Increased stress on other components from inadequate dampening
• Premature wear of suspension components like legs and runners

Replace yours today with this genuine OEM LG part to restore a quiet wash experience. This replacement assembly ensures optimum vibration control. It is also compatible with Sears/Kenmore models.

This replacement connector hose routes water between the refrigerator water valve and the dispenser or ice maker, restoring reliable water flow and helping prevent leaks. It's a direct-fit service part used where the factory hose is worn or damaged. What it does
