Parts for Lg LDF7811BB-01: Sump Assy Parts

The Affresh Dishwasher Cleaner is an OEM accessory designed specifically for Whirlpool brand dishwashers. This citrus-scented tablet removes residue, odor-causing soils, and food particles from the dishwasher tub and gasket area during the cleaning cycle. Symptoms of a buildup include unwanted odors emanating from the dishwasher, especially after opening the door. Over time, residue and grime accumulate in hard-to-reach areas and provide an environment for mold and mildew growth.

Regular cleaning helps prevent this by removing leftover soils before they harden or encourage bacterial activity. The Affresh tablet utilizes a unique blend of cleaning ingredients that target soils and biofilms through a combination of powerful scrubbing action and natural cleaning enzymes.

As the #1 recommended dishwasher cleaner brand, Affresh is also compatible for use in Maytag, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and select Kenmore dishwashers for consistent cleanliness and freshness. The package includes six tablets 4.2 ounces

This dishwasher sump gasket seals the joint between the sump assembly and the tub to prevent leaks and maintain wash performance. Replace it if the old seal is worn, flattened, cracked, or damaged to stop water escaping beneath the unit.

• Creates a watertight seal where the sump attaches to the tub
• Helps prevent water leaks from the base of the dishwasher
• Supports proper circulation and overall wash performance
• Common failure signs: puddles under the unit, leaks during a cycle, or a visibly torn/deformed gasket

• Disconnect power and turn off the water supply before servicing
• Access the sump from inside the tub (remove lower rack, spray arm, filters, and sump cover) or from below, depending on model
• Clean mating surfaces; install the new gasket evenly without twists or gaps
• Reassemble and run a short cycle to check for leaks

The Diverter Motor Assembly is an OEM part for LG dishwashers. It is a critical component used to control the direction of water flow within the dishwasher, ensuring that water is properly diverted between the different spray arms during various wash cycles.

Symptoms of a failing Diverter Motor Assembly include:

• Inadequate cleaning of dishes, with some areas remaining dirty
• Unusual noises, like humming or clicking, indicating the diverter motor is struggling to operate
• Error codes displayed on the dishwasher that relate to water distribution problems
• Water not reaching all spray arms

Causes of a bad diverter motor can include wear and tear from regular use, electrical issues such as faulty wiring or motor failure, and mechanical obstructions or debris that prevent the diverter from moving smoothly.

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

The Cam Motor Shaft Seal is an OEM part for LG dishwashers. It provides a watertight seal around the cam motor shaft, preventing water from leaking into the motor and other electrical components. This seal is essential for maintaining the efficiency and safety of the dishwasher.

You should replace the cam motor shaft seal if it becomes worn out or damaged. Common causes of a bad shaft seal include regular wear and tear, exposure to high temperatures and chemicals from detergents, or improper installation. A compromised seal can lead to leaks and potential damage to the motor.

Symptoms of a bad cam motor shaft seal include:

• Water leaks from the bottom of the dishwasher
• Unusual noises during the wash cycle
• Reduced efficiency in cleaning due to water escaping
• Visible damage or wear on the seal

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

This dishwasher spray arm, also called a blade, directs high-pressure wash water through its jet ports and rotates to cover the tub. Replace a cracked, warped, or clogged blade to restore spray coverage and cleaning performance.

• Distributes wash water through multiple jets during wash and rinse cycles
• Rotates using water pressure for even, consistent spray coverage
• Helps remove soils from dishes throughout the tub
• Helps resolve poor cleaning, weak spray, a non-spinning arm, or visible cracks/deformation

• Disconnect power and shut off water supply before servicing
• Open the dishwasher and clear access to the spray arm (remove rack(s) if needed)
• Release the retaining clip or nut, lift off the old arm, and clear any debris at the hub
• Install the new arm, secure the fastener, ensure it spins freely, restore utilities, and run a test cycle

The PUMP MOTOR is an OEM part for LG washing machines. It is an electric motor that powers the pump responsible for circulating water inside the washing machine tub and through hoses during all wash cycles. Efficient water flow is necessary for proper cleaning and rinsing performance.

Causes of a bad pump motor can include mineral buildup inhibiting smooth rotation, worn motor windings affecting current flow, or damage from water damage into the motor housing.

Symptoms of a bad pump motor include:

• Incomplete or failed wash cycles  
• Inability to fill or drain properly
• Strange noises emanating from the pump area
• Leaks or water issues related to poor water circulation

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

The Dishwasher Circulation Motor is an OEM part for LG dishwashers. It plays a crucial role in the dishwasher's operation by pumping water through the spray arms during the wash cycle, ensuring that dishes are thoroughly cleaned.

Over time, the circulation motor can fail due to normal wear and tear, electrical issues, or blockages caused by debris. A malfunctioning motor can lead to inefficient cleaning and increased noise levels. Regular maintenance and avoiding overloading the dishwasher can help extend the motor's lifespan.

Symptoms of a bad circulation motor include:

• Dishes not being cleaned properly
• Unusual noises during the wash cycle
• The dishwasher not completing cycles
• Water not circulating within the dishwasher

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

• Inadequate heating resulting in lukewarm final rinses  
• Fault codes or cycle interruptions during prolonged heating 
• Diminished drying performance from lack of hot air
• Noticeable decline in overall cleaning from colder wash water

Causes related to mineral deposits clogging component coils over many years of use. Damage may also be caused by harsh chemicals left inside during wash cycles.

Compatible models include some Kenmore and Sears dishwashers.

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

The Check Valve is an OEM part for LG dishwashers. It prevents the backflow of water into the dishwasher, ensuring that water only flows in the intended direction. This helps maintain the efficiency of the washing cycle and prevents contamination of clean dishes.

The check valve can fail due to reasons such as wear and tear, blockage from debris or hard water deposits, or damage from high water pressure. Over time, the internal components can degrade, leading to improper sealing.

Symptoms of a bad check valve include:

• Water backing up into the dishwasher
