Lg Dishwasher LDS5540BB 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

The Dishwasher Inlet Valve is an OEM part for LG dishwashers. This valve controls the flow of water into the dishwasher, opening to allow water in at the start of the wash cycle and closing to prevent any further water entry once the desired level is reached. It ensures that the dishwasher receives the correct amount of water for optimal cleaning performance.

Causes of a bad inlet valve can include mineral deposits or debris clogging the valve, electrical issues, or general wear and tear from prolonged use. A malfunctioning valve can lead to improper water levels and potential flooding.

Symptoms of a bad dishwasher inlet valve include:

• The dishwasher not filling with water
• Water entering the dishwasher even when it is turned off
• Incomplete or prolonged wash cycles
• Leaks or puddles of water under the dishwasher

This OEM LG part is also compatible with Sears/Kenmore models.
