1. Quick Drainage: The motor drives the impeller to create a vacuum, rapidly pumping out wastewater from the washing machine and discharging it outdoors or into the sewer. 2. Prevents Backflow: The internal check valve automatically shuts off when the pump stops working, preventing wastewater from flowing back into the drum and contaminating the laundry. 3. Adaptable Installation: Whether it's a drum or agitator washing machine, or a rise or lowrise building, it flexibly adapts to different installation environments and drainage locations. 4. Operation: If the drain pump fails, the washing program is interrupted or an alarm is triggered. Its normal operation is a crucial guarantee for the overall performance and lifespan of the washing machine.
