    Why is my LG Washer not filling properly?
    • S
      Sean CaldwellAug 22, 2025
      If your LG Washer is not filling properly, ensure that both the hot and cold water faucets are fully turned on. Check that the inlet hoses are not kinked or clogged. Also, make sure the inlet filters on the fill valves are not clogged and that the washer door is completely closed. Remember, this is a High-Efficiency (HE) washer, so the water will not normally cover the clothes.

      If your LG Washer displays the UE UNBALANCE ERROR, try these solutions: * If the load is too small, add additional items to allow the washer to balance the load. * If heavy articles are mixed with lighter items, always try to wash articles of somewhat similar weight. * If the load is out of balance, manually redistribute the load if articles have become tangled.

    How to stop LG WM4000H A from making loud banging noises?
    • J
      Janet GoodwinAug 29, 2025
      If your LG Washer is making loud banging noises while filling with water, it could be due to the plumbing in your home moving or flexing when the water valves in the washer shut off. For best results, install water hammer arrestors between the fill hose and the washer. Alternatively, the household water supply pressure may be very high; in this case, adjust the household water supply regulator to a lower pressure or contact a plumber.
