This is the upper crankcase or housing that encloses the pump impeller assembly in the dishwasher. It provides a sealed chamber for the pump motor to circulate and drain water during wash and drain cycles. Replace this housing if it is cracked, leaking, or damaged, which can cause water leaks under the dishwasher or poor wash and drain performance.

This is the lower case housing for the dishwasher's circulation pump assembly. It encloses and supports the pump motor that recirculates water through the spray arms during wash and rinse cycles.

The Blower Motor Assembly is an OEM replacement part for LG dishwashers. Located inside the wash cavity, it functions to distribute heated air throughout during the dry cycle. Rapid rotation of the blower motor blades works to eject moisture from dishes and ensure thorough drying. 

Causes of a bad blower motor include failure of the motor itself, cracks in the blades that disrupt airflow, or bearing issues preventing proper rotation.

Symptoms include:

• Dishes still feeling damp after a cycle 
• Puddles of water remaining in the bottom of the dishwasher
• Water droplets on upper racks/dishes
• The motor producing grinding/squealing noises on startup

It is also compatible with some Kenmore dishwashers using LG components. 

This sensor monitors water flow inside the dishwasher to ensure proper water circulation during wash and rinse cycles. It sends signals to the control board to regulate water intake and pump operation. Replace this sensor if the dishwasher displays error codes related to water flow, fails to fill properly, or stops mid-cycle due to incorrect flow detection.

Channels wastewater from your dishwasher to the household drain. Replace if cracked, kinked, clogged, or leaking to restore proper drainage during cycles.

Closes off the bottom of the dishwasher cabinet to protect internal components. Replace if the panel is cracked, missing, or won't stay secured.

This is a damper and sound shield assembly that attaches to the dishwasher tub to reduce noise and vibration during wash and drain cycles. It acts as an insulating barrier that absorbs sound energy from water spraying and motor operation. Replace this part if your dishwasher has become noticeably louder than usual or if the existing sound shield is damaged, warped, or has come loose.

This is a common fastening nut used to secure panels, trim, or components on compatible LG appliances. It provides a simple, reliable way to hold mating parts in place and restore proper fit and function. What it does

• Secures panels, brackets, or hardware to prevent movement or vibration
• Stops rattling or loose parts caused by a missing or worn nut
• Restores proper alignment when replacing damaged or stripped fasteners
• Works where a standard threaded nut is required for reassembly

• One common nut as pictured

• Disconnect power and water before servicing the appliance
• Use the properly sized wrench or socket to avoid rounding the nut
• Do not overtighten; tighten until snug and secure per OEM torque guidance
• Replace like-for-like—thread size and type match the original

This clamp secures hoses or wiring to the appliance chassis to prevent movement, chafing, and vibration-related wear. It helps keep connections stable so hoses and wires stay in place during normal use. What it does:

• Holds water, drain or vent hoses in position to reduce strain and prevent rubbing
• Keeps wiring harnesses routed and fastened to avoid chafing or accidental disconnection
• Reduces vibration-related noise caused by loose hoses or wires
• Helps prevent hose kinks and unintended movement that can lead to leaks or intermittent electrical issues

• One clamp

• Disconnect power to the appliance before servicing; shut off water supply if working with water lines
• Remove panels as needed to access the hose or wiring route, then replace the clamp in the same orientation
• Use appropriate pliers or a screwdriver if required; do not overtighten or deform the hose or wiring
• If the original clamp was secured with a fastener, retain and reuse it only if undamaged; replace any stripped or broken hardware
