    Why are my clothes still wrinkled after using STEAM FRESH™ on my LG DLGX3371W Dryer?
    • M
      Mr. Jeffrey NobleAug 18, 2025
      If your LG Dryer leaves garments still wrinkled after using the STEAM FRESH™ option, it may be due to overloading or mixing different types of garments. For best results, use small loads of 1 to 5 similar items.

      Ernest GarciaAug 20, 2025
      If your garments are too damp or too dry after using the REDUCE STATIC option on your LG Dryer, it's likely that the correct drying options weren't selected. You should manually select the load weight before starting the REDUCE STATIC option.

    How to remove odors from clothing after using STEAM FRESH™ cycle in my LG DLGX3371W Dryer?

      Todd HansenAug 23, 2025
      If odors remain in clothing after using the STEAM FRESH™ cycle on your LG Dryer, it means that the STEAM FRESH™ cycle did not remove the odor completely. For fabrics with strong odors, it's recommended to wash them in a normal cycle.

      Colleen FryAug 28, 2025
      If there are no creases left on garment after STEAM FRESH™ cycle in your LG Dryer, it is because the function of this cycle is to remove wrinkles from fabric. Use an iron to make creases.
