    Why is water draining slowly from my LG WM3555HWA Washer/Dryer?
    • K
      Kathleen HarrisonAug 6, 2025
      If water is draining slowly from your LG Washer/Dryer, check the drain hose for clogs, kinks, or pinches behind or under the washer. Also, make sure that the end of the drain hose is not more than 96 inches (2.4 m) above the bottom of the washer; if it is, lower it.

    How to fix the IE inlet error on my LG WM3555HWA Washer/Dryer?

      David CollinsAug 10, 2025
      To fix the IE inlet error on your LG Washer/Dryer, ensure that the water supply faucets are fully open. Check the water inlet hoses for kinks, pinches, or crushing behind or under the washer. Clean the water inlet filters. Verify that the water supply pressure to the faucet or house is adequate by checking another faucet. Disconnect the water inlet hoses and flush out any dirt. Note that using leak-limiting hoses is not recommended as they can falsely trip and prevent filling.

Also, verify that the end of the drain hose is not more than 96 inches (2.4 m) above the bottom of the washer and adjust if necessary.

    Why won't my LG Washer/Dryer start?
    • J
      Jason PhillipsAug 18, 2025
      Your LG Washer/Dryer might not start due to several reasons. First, ensure the power cord is securely plugged into an electrical outlet. Check if the circuit breaker or fuse has tripped or blown and reset or replace it if necessary. Make sure the water supply is turned on fully at both hot and cold faucets. Also, confirm that you've properly set the cycle, closed the door completely, and pressed the Start/Pause button. If the control panel is off, press the Power button to turn on the washer. In case of extremely low water pressure, check another faucet in the house. If the washer is too cold, allow it to warm up before turning it on.

    Why is detergent not dispensing correctly in my LG WM3555HWA?
    • S
      Sarah WalkerAug 23, 2025
      If detergent is not dispensing correctly in your LG Washer/Dryer, it could be due to several factors. Ensure that you are placing detergent and additives in the correct dispenser compartments and that the dispenser drawer is fully closed before starting the cycle. Using too much detergent can also cause issues; use the amount recommended by the manufacturer and consider diluting it with water to the maximum fill line to prevent clogging. Insufficient water supply can also be a factor, so make sure both hot and cold water faucets are fully open. Note that a small amount of detergent residue is normal, but if it builds up, refer to the cleaning instructions.

    What to do if my LG Washer/Dryer is not filling with water properly?
    • C
      Catherine BaileyAug 27, 2025
      If your LG Washer/Dryer isn't filling properly, first ensure that both the hot and cold water faucets are turned on all the way. Check that the inlet hoses are not kinked or clogged. Also, make sure the inlet filters on the fill valves are not clogged. Close the door completely, ensuring nothing obstructs it. Note that this high-efficiency (HE) washer may have different water level settings than conventional washers, and the water will not normally cover the clothes.

    How to stop my LG Washer/Dryer from making loud banging noises when filling with water?
    • J
      James MarshallSep 1, 2025
      Loud banging noises while your LG Washer/Dryer is filling with water can be due to high household water supply pressure. Adjust the household water supply regulator to a lower pressure or contact a plumber. For best results, install water hammer arrestors (purchased separately at a hardware or home improvement store) between the fill hose and the washer.
