Lg Spray Arm & Related

The Nozzle Assembly is an OEM part for LG dishwashers, designed to enhance the efficiency and effectiveness of the water spray during the wash cycle. This component directs water to the dishes to ensure thorough cleaning and rinsing. Positioned strategically within the dishwasher, the nozzle assembly plays a role in distributing water evenly across all dishes, regardless of their placement in the rack.

The causes for these issues can range from clogs within the nozzle from food particles or mineral deposits from hard water, to physical damage that can occur through wear and tear or during loading and unloading of dishes.  

Symptoms of a failing Nozzle Assembly include:

• Dishes not being cleaned properly, with food particles or soap residue remaining after cycles
• Water not reaching all areas of the dishwasher, leading to uneven cleaning
• Decreased water pressure, which can affect the dishwasher's ability to remove tough food stains

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

The Upper Spray Arm is an OEM part for LG dishwashers. This part is located at the top of the dishwasher tub, responsible for spraying water and detergent onto the upper rack of dishes during the wash cycle.

Causes of a bad Upper Spray Arm can include mineral buildup or debris clogging the spray holes, physical damage from impact or foreign objects, or wear and tear over time.

Symptoms of a faulty Upper Spray Arm include:

• Incomplete or ineffective washing of dishes on the upper rack
• Water not spraying evenly or not spraying at all from the upper arm
• Clogged or blocked spray holes
• Loud noises or grinding sounds during the wash cycle

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

This lower spray arm (nozzle assembly) mounts at the bottom of the tub and spins to deliver pressurized wash water across dishes. Replacing a cracked or clogged arm restores even spray coverage and helps resolve poor cleaning results.

• Distributes wash water from the pump across the lower rack area
• Rotates to provide even spray coverage and rinsing
• Replaces warped, cracked, or clogged arms that reduce cleaning or cause noise
• Common symptoms: dishes not getting clean, spray arm not turning, visible damage or blockages

• Disconnect power at the breaker; open the door and remove the lower rack
• Release the old arm from the center hub (turn/unsnap retainer) and lift off
• Clear debris from the hub and filter area; seat the new arm fully and verify free rotation
• Restore power and run a short cycle to proper spray action

This nozzle assembly directs high-pressure wash water through its jets for even cleaning inside the dishwasher. Replacing it restores consistent spray coverage and wash performance. What it does:

• Distributes wash water through spray jets during wash and rinse cycles
• Uses water pressure to rotate and reach all rack areas
• Replaces broken, warped, or clogged nozzles that restrict flow
• Common symptoms include poor cleaning results, spray arm not spinning, unusual noise, or leaks at the spray hub

• 1 nozzle assembly

• Disconnect power and water supply before servicing
• Pull out the rack as needed; release the locking tab or nut to remove the old nozzle
• Inspect and transfer any O-rings/gaskets if present; seat the new assembly fully for a leak-free seal
• Run a short test cycle to check for leaks

This nozzle guide positions and supports the dishwasher spray nozzle on the rack, helping it align with the rear feed port for reliable water flow to the spray arm and consistent cleaning performance.

• Aligns the rack nozzle with the dishwasher's water feed port
• Stabilizes the nozzle to help ensure steady spray delivery
• If worn or broken, you may notice poor cleaning on the affected rack
• Can also cause intermittent spray or drips at the rear nozzle connection and difficulty engaging the rack nozzle

• Disconnect power and turn off the water supply before servicing
• Pull the rack forward, remove rack end caps/stops, and lift the rack out
• Release the old guide from the nozzle assembly; install the new guide and verify smooth movement and proper alignment with the feed port
• Reinstall the rack, restore power/water, and run a short test to check spray and for leaks

The Water Supply Tube is an OEM part for LG dishwashers, designed to channel water effectively to various parts of the dishwasher during operation. This component allows the unit to fill, rinse, and clean dishes efficiently. The water supply tube is strategically positioned to distribute water to the spray arms, ensuring a thorough and even cleaning cycle by reaching all dishes, regardless of their placement in the racks.

Causes of these issues can range from physical damage due to impact or mishandling, clogs from mineral deposits or debris in the water, to general wear and tear over time.

Symptoms of a malfunctioning Water Supply Tube include:

• Inadequate water flow to the spray arms 
• Leakage or dripping water from the tube 
• Unusual noises during the water filling phase 

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