    What to do if garments are too damp or too dry after using REDUCE STATIC on my LG DLGX4271 /01?
    • S
      Sandra ReedAug 17, 2025
      To prevent garments from being too damp or too dry after using the REDUCE STATIC option on your LG Dryer, manually select the load weight before starting the REDUCE STATIC option. The issue is likely due to incorrect drying options being selected.

    Why is the indicator light on during the drying cycle of my LG DLGX4271 /01?

      If indicator lights are on during the drying cycle of your LG Dryer, it may be due to a water supply error. Check the steam feeder drawer to ensure it's filled with water to the MAX line, properly seated, and fully closed. Turn the dryer off, then restart the steam cycle. Do not use distilled water. If the pump is not working, unplug the dryer and call for service.

    Why do odors remain in clothing after using STEAM FRESH™ on my LG Dryer?
    • S
      Susan WillisAug 22, 2025
      If odors remain in clothing after using the STEAM FRESH™ cycle on your LG Dryer, it's because the STEAM FRESH™ cycle didn't completely remove the odor. For fabrics with strong odors, wash them in a normal cycle instead.

    How to prevent garments from being wrinkled after STEAM FRESH™ cycle in my LG Dryer?
    • J
      Julie HodgeAug 26, 2025
      To address garments that are still wrinkled after using the STEAM FRESH™ cycle on your LG Dryer, try using smaller loads of 1 to 5 items, and load similar-type garments. This issue is caused by having too many or too different types of garments in the dryer at once.

    Why does water drip from the nozzle when the steam cycle starts on my LG Dryer?
    • D
      Denise RoweAug 27, 2025
      If water drips from the nozzle when the steam cycle starts on your LG Dryer, this is normal. It's just steam condensation, and the dripping will stop shortly.

    What to do if there are no creases left on garment after STEAM FRESH™ cycle in my LG DLGX4271 /01?
    • J
      Joseph ClineAug 30, 2025
      If you find there are no creases left on garments after using the STEAM FRESH™ cycle on your LG Dryer, it's because the function of this cycle is to remove wrinkles from fabric. Use an iron to make creases if desired.

    Why does water drip from the door during the steam cycle of my LG DLGX4271 /01?
    • E
      Elijah MortonSep 2, 2025
      If water drips from the door during the steam cycle of your LG Dryer, this is normal. It's just steam condensation on the door surface.

    Why is steam not visible during the steam cycle of my LG DLGX4271 /01?
    • J
      Jessica FosterSep 5, 2025
      If steam is not visible during the steam cycle on your LG Dryer, this is normal. Steam vapor is difficult to see when the door is closed.

    Why doesn't the drum turn during the steam cycle of my LG Dryer?
    • H
      hfischerSep 7, 2025
      If the drum does not turn during the steam cycle of your LG Dryer, this is normal. The drum is turned off so that the steam vapor remains in the drum.

    Why can't I see steam vapor at the beginning of the cycle in my LG DLGX4271 /01 Dryer?
    • L

      If you cannot see steam vapor at the beginning of the cycle on your LG Dryer, this is normal. Steam is released at different stages of the cycle for each option.
