      The LE1 FOREIGN OBJECT ERROR on your LG washer indicates that foreign objects are caught between the pulsator and the inner tub. Turn the washer off then on again. Press the Spin button without selecting a cycle to drain and spin the load. When the Spin cycle is completed, empty the tub and find and remove any objects caught in the pulsator.

      To resolve the UE UNBALANCE ERROR on your LG washer, try adding more items to balance the load. Ensure you're washing articles of similar weight for even distribution during spinning. If items are tangled, manually redistribute them to allow the washer to rebalance automatically.

    Why does my LG Washer show an IE INLET ERROR?
    • S
      Sarah LaneAug 25, 2025
      The IE INLET ERROR on your LG washer can occur for several reasons. First, ensure that the water supply faucets are fully open and that the water inlet hoses are not kinked, pinched, or crushed. Check the water inlet filters for clogs and clean them if necessary. Also, verify that the water supply pressure to the faucet is adequate by checking another faucet in the house. Disconnect the water inlet hoses and flush them out to remove any dirt. Avoid using leak-limiting hoses. Finally, ensure the end of the drain hose is higher than 29.5 inches above the bottom of the washer.

      Jerry CarneyAug 27, 2025
      If your LG washer won't turn on, first check that the power cord is properly plugged into a grounded outlet. Also, verify that the house fuse hasn't blown, the circuit breaker hasn't tripped, or there isn't a power outage. Reset the circuit breaker or replace the fuse, but do not increase the fuse capacity.
