5. Operation
The drain pump operates automatically as part of your dishwasher's wash cycle. When activated, the pump's motor spins the impeller, creating suction to draw water from the dishwasher tub and push it through the drain hose to your household plumbing. Proper operation ensures that dirty water is removed, allowing for clean rinse cycles and preventing standing water in the tub. The pump will engage multiple times throughout a wash cycle, typically after the main wash and rinse phases.
6. Maintenance
To ensure the longevity and efficient operation of your drain pump, periodic inspection is recommended. Check the drain hose for kinks or blockages. Occasionally, food debris or foreign objects may accumulate in the pump's filter or impeller area, which can impede drainage. If accessible, clear any obstructions after disconnecting power to the dishwasher. Do not use harsh chemicals to clean the pump or its surrounding components, as this may cause damage.
