There are a few potential reasons why an LG top-loading washer may not spin but continues to drain water and fill again without stopping. Some possible causes include:
Lid or Door Switch Issue: Many top-loading washers have a lid or door switch that prevents the washer from spinning when the lid or door is open. If this switch is faulty or not making proper contact, the washer may not detect that the lid is closed, and therefore, it won't go into the spin cycle.
Motor or Motor Control Board Problem: The motor and motor control board are responsible for controlling the spinning action of the washer. If either of these components is faulty, the washer may not spin as intended.
Belt or Drive System Issue: Top-loading washers use belts or a drive system to transfer power from the motor to the drum. If the belt is broken, loose, or worn out, it can prevent the drum from spinning.
Unbalanced Load: Sometimes, an unbalanced load can trigger safety features in the washer that prevent it from spinning. If the load is unevenly distributed in the drum, the washer may not be able to enter the spin cycle to avoid damaging the machine.
Control Board Malfunction: The control board is the brain of the washing machine, and if it experiences a malfunction or error, it may not send the proper signals to initiate the spin cycle.
To troubleshoot and fix the issue, consider the following steps:
Check the lid/door switch: Ensure that the lid or door is closing properly and that the lid/door switch is functioning correctly. If the switch is defective, it may need to be replaced.
Inspect the motor and drive system: Examine the motor, belts, and drive system for any visible signs of damage or wear. If any components appear to be faulty, they may need to be repaired or replaced.
Check for an unbalanced load: Open the washer, redistribute the clothes evenly in the drum, and try running the spin cycle again.
Restart the washer: Sometimes, a simple reset can fix electronic glitches. Try unplugging the washer for a few minutes, then plug it back in and see if the issue persists.
If you're not comfortable performing these troubleshooting steps yourself, it's best to contact a professional appliance repair technician to diagnose and fix the problem safely. They will have the expertise and tools to identify the exact cause and provide the necessary repairs.
