5. Operation
The drain pump operates automatically as part of the washing machine's cycle. Once installed correctly, it will activate during the drain phase to remove water from the wash tub. No manual operation of the pump itself is required.
- Ensure the washing machine's main power is on.
- Select the desired wash cycle on your washing machine.
- The pump will engage automatically during the drain and spin cycles to expel water.
6. Maintenance
Regular maintenance of the drain pump can extend its lifespan and prevent common issues. The primary maintenance task involves cleaning the pump filter.
- Accessing the Filter:
- Always disconnect the washing machine from the power supply before attempting to clean the filter.
- Locate the pump filter, typically found behind a small access panel at the bottom front of the washing machine.
- Place a shallow pan or towels beneath the filter access to catch any residual water.
- Cleaning the Filter:
- Carefully unscrew or unclip the filter cover.
- Remove any lint, debris, coins, or other foreign objects that may have accumulated in the filter.
- Rinse the filter under running water to remove any remaining residue.
- Reassembly:
- Ensure the filter is clean and properly seated before screwing or clipping the cover back into place.
- Ensure the cover is tightly sealed to prevent leaks.
- Close the access panel.
It is recommended to clean the pump filter every 3-6 months, or more frequently if you notice drainage issues or excessive lint in your laundry.
