- Reassemble the Filter: Once clean, reattach the filter securely and ensure there are no leaks.
Faulty Lid Switch
In top-loading washing machines, the lid switch ensures the machine only operates when the lid is closed. A defective lid switch can interrupt the drain cycle, preventing the machine from draining.
Testing and Replacing the Lid Switch
- Test the Switch: Use a multimeter to check for continuity in the lid switch. If there’s no continuity, the switch is faulty.
- Replace the Switch: Purchase a compatible lid switch and follow the manufacturer’s instructions to install it. Typically, this involves removing the old switch and wiring the new one in its place.
Obstructed Drain Pump Impeller
The drain pump impeller plays a crucial role in moving water out of the washing machine. Therefore, if it becomes obstructed by debris or is worn out, the pump cannot function correctly. This can lead to drainage issues that may require immediate attention.
How to Inspect and Repair the Impeller
To begin, access the pump by referring to your machine’s manual, which will guide you in locating and accessing the drain pump. Once you have access, inspect the impeller by removing any visible debris and checking it for signs of wear or damage. If you find debris present, be sure to clean it out thoroughly. However, if the impeller shows signs of damage, you will need to replace the entire drain pump for optimal performance.
