Several factors can cause a top-loading washing machine to not drain completely, leaving standing water at the bottom of the tub. Here are a few possible causes:
Clogged Drain Hose: A clogged or partially blocked drain hose is a common reason for incomplete drainage. Over time, debris, lint, or foreign objects can accumulate in the hose, obstructing the flow of water. Check the drain hose for any blockages and clear them if necessary.
Pump Issues: The pump is responsible for removing water from the washing machine. If the pump is malfunctioning or damaged, it may not be able to effectively drain the water. A faulty pump may need to be repaired or replaced by a professional.
Pump Filter or Coin Trap: Some washing machines have a pump filter or coin trap that can become clogged with lint, coins, or other debris. This can impede the drainage process. Consult your washing machine's manual to locate and clean the pump filter or coin trap regularly.
Drainage Height: The drainage height or position of the drain hose can affect proper water flow. If the drain hose is positioned too high or too low, it can impede drainage. Ensure that the drain hose is positioned correctly, usually at a height between 30 and 48 inches from the floor.
Improper Installation: If the washing machine was not installed correctly, it may not drain properly. Make sure the drain hose is securely connected and not kinked or bent, as this can restrict water flow.
Laundry Load Imbalance: Uneven distribution of laundry within the tub can cause an imbalance during the spin cycle, preventing proper drainage. Ensure that the laundry load is evenly distributed and not overloaded.
If you're unable to identify or resolve the issue on your own, it is recommended to consult a professional appliance technician or contact the manufacturer's customer support for further assistance. They can diagnose the problem and provide the necessary repairs or guidance to ensure proper drainage in your washing machine.
