Lg Dishwasher LDF7932BB Noisy

The Sump and Motor Assembly is an OEM replacement part for LG dishwashers. As a functional pumping component, it circulates water and removes debris during dish cycles.

Symptoms of a bad sump and motor assembly can include:

• Inability to properly fill or drain water from the dishwasher
• Leaks or excessive pooling of water inside the unit 
• Loud knocking or grinding noises from the motor area

Causes of failure may involve a clogged or cracked sump housing impairing flow, or wear of the motor bearings degrading power output over time.

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

This impeller assembly spins on the dishwasher's pump to move water through the system. Replacing a worn or broken impeller restores proper water flow, helping maintain wash performance and reducing noise from the pump area. What it does:

• Moves water through the dishwasher's pump system for circulation and cleaning
• Helps maintain correct water flow and spray pressure to the spray arms
• Typical failure signs: poor cleaning or weak spray, unusual grinding/humming from the sump, or slow/no draining depending on which impeller has failed
• Physical clues include damaged/broken blades or a loose fit on the motor shaft

• 1 impeller assembly

• Disconnect power and turn off the water supply before servicing
• Remove the lower rack and filters to access the pump/sump; follow your model's service information
• Note the impeller's orientation; transfer any reusable seals or hardware from the original as required
• After reassembly, check for leaks and verify the pump spins freely before running a test cycle

Replacement inlet valve assembly that controls water entering the washer so cycles fill properly and the appliance runs as expected. Installs at the water inlet to restore proper filling and stop leaks caused by a faulty valve. What it does:

• Opens and closes the water path into the washer to allow correct fill levels during wash cycles.
• Stops or reduces water flow when the valve is closed to prevent overfilling.
• Common symptom fixes: washer won't fill, intermittent filling, continuous filling, or water leaking at the inlet connection.
• Works with the appliance's inlet hose connections and electrical solenoid controls.

• Disconnect power and turn off the home's water supply before starting any repair.
• Remove the access panel, disconnect inlet hoses and electrical connectors, then replace the valve with the correct orientation and seals.
• After installation, restore water and power, run a short fill cycle, and check all connections for leaks.
