This wire harness routes power and signals between the washer's control and multiple components. Replace a damaged harness to restore dependable operation when wiring is cut, brittle, or connectors are heat-damaged or corroded.

• Distributes electrical power and communication between the control board and components such as the motor, pump, valves, door lock, and sensors
• Maintains safe, reliable connections when insulation and terminals are intact
• Typical failure signs: intermittent operation, no start, specific loads not working (pump/motor/valves), or error codes traced to wiring faults
• Visible damage like chafed wires, broken connector locks, or burned/corroded terminals indicates replacement

• Disconnect power and turn off water supply before servicing; wear cut-resistant gloves
• Photograph and label connectors; move one plug at a time from old to new to avoid miswiring
• Route along original clips, channels, and grommets; keep wiring clear of sharp edges and moving parts
• Ensure all connectors are fully seated; test operation before final reassembly

The Nozzle Connector is an OEM part for LG washers. This connector piece attaches to the water supply lines and direct tub fill nozzle, directing water into the washer tub during fill cycles. It allows water to be distributed evenly around the tub perimeter during fills to optimize cleaning performance.

Causes of a bad connector can include cracks, leaks, or blockages from mineral buildup that disrupt water flow.

Symptoms of a bad connector include:

• Uneven or inadequate water levels in the tub during fills
• Slow or inefficient fills requiring multiple attempt
• Water leaks from the connector area
• Mineral buildup visibly clogging the connector

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

This inlet hose carries water into the washer's fill system during wash and rinse cycles. Replacing a cracked or leaking hose restores proper filling and helps prevent water around the appliance from seepage at the connections.

• Routes incoming water to the washer's fill path during the fill cycle
• Helps maintain a watertight connection between the supply and the machine
• Replace if you see cracks, bulges, kinks, or active leaks
• Helps resolve water on the floor during fill, intermittent fill errors, or slow/no fill due to restricted flow

• Unplug the washer and turn off the water supply valves before starting
• Place a towel or pan to catch residual water and relieve line pressure
• Note hose routing/orientation; install the new hose without kinks and hand-tighten fittings
• Restore water and power, then check all connections for leaks during a short fill test

This drum spider supports and centers the inner tub in front-load washers. It bolts to the drum and couples to the drive shaft to keep spins smooth and balanced, reducing noise and vibration as the original wears.

• Supports and centers the inner spin basket within the outer tub
• Transfers drive power through the shaft to spin the drum
• Maintains drum alignment to help prevent rubbing and noise
• When worn: loud banging/rumbling on spin, excessive vibration, metallic scraping, unbalance/spin errors, wetter-than-normal loads

• Disconnect power and water; move the washer to a stable work area
• Access requires removing panels, the door boot, and separating the tub to lift out the inner basket
• Clean mating surfaces; install and tighten bolts in a crisscross pattern to ensure even seating
• Inspect rear tub bearings and seal while open; reassemble and run a test spin to check for leaks and vibration

The Pcb Assembly is an OEM part for LG washer/dryer combo units. This control board serves as the user interface for selecting and controlling various settings and cycles. It provides you with a user-friendly interface to conveniently operate and monitor the functions of your appliance.

A bad display control board interface can occur due to electrical issues, component failure, or other internal malfunctions. If you notice symptoms such as the display not functioning properly, unresponsive buttons or controls, or error messages appearing on the screen, it may be time to replace the display control board interface.

Symptoms of a bad display control board interface include:

• Display not functioning properly
• Unresponsive buttons or controls
• Error messages appearing on the screen

Restore the function of your LG washer/dryer combo by replacing the faulty display control board interface with this genuine OEM part.

This LG replacement part is also compatible with select Kenmore models.
 

This Cover Cap replaces a missing or damaged cosmetic cap to restore a clean finished appearance and help protect underlying fasteners and openings from dirt. It's a simple, low-cost fix for visible damage. What it does:
