Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Poor cleaning performance or residue left on dishes
• Weak or absent spray-arm operation
• Unusual humming, grinding, buzzing, or moaning during operation
• Water remaining or pooling in the tub after a cycle
• Dishwasher stopping during the cycle when the pump/motor assembly fails

Check Before Replacing

• With power disconnected, inspect and clean the filters and accessible sump area for food debris or foreign objects before attributing circulation problems to the assembly.
• Confirm that the dishwasher fills with water and that the spray arms can rotate freely by hand when the appliance is not running.
• Observe whether water is being circulated during the wash phase and whether the appliance drains during the drain phase; these observations help distinguish circulation symptoms from unrelated fill or control problems.
• Before service, disconnect electrical power, shut off the water supply, and use appropriate hand protection.

Installation Notes

• Disconnect electrical power and shut off the dishwasher water supply before installation.
• Because this is a combined sump-and-pump assembly with electrical and water connections, verify the appliance model and obtain the model-specific service procedure before removal.
• Keep track of wire and hose connections during removal and reconnect them to the corresponding locations on the replacement assembly.
• Inspect mating seals and connection areas for damage or debris before reassembly; do not reuse damaged sealing components.
• After installation, check for leaks and confirm circulation and draining before returning the dishwasher to normal use.
