Is This the Right Part?

Common Symptoms

• Visible water or moisture beneath the dishwasher when a leak is traced to the lower sump area.
• A leakage-related alert or error after moisture is detected, if an actual sump-area leak is confirmed.
• Poor wash-water movement or drainage symptoms when the sump area is damaged or obstructed; attached pumps, hoses, and filters must also be ruled out.

Check Before Replacing

• Disconnect power at the circuit breaker before inspecting beneath or inside the dishwasher.
• Check for visible cracking, distortion, or water traces around the lower sump area and its connected components; do not assume the sump is the cause solely from a leak symptom.
• Rule out the water-supply hose, drain-hose connections, door seal, detergent oversudsing, and spray-arm/nozzle obstructions before attributing a leak to the sump.
• With power off, remove and inspect the accessible filter area for debris or obstruction; follow the model’s care instructions and avoid forcing components.
• If replacement is being considered, compare the original part number and the dishwasher model against the parts diagram.
