LG Dryer F0 / Filter Out error code

Difficulty: Easy · Cost: $0 · Duration: 2m

The Filter Out display or flashing INSERT FILTER message means your LG dryer detected that the lint filter is not seated correctly in its housing. A sensor inside the dryer monitors whether the filter is properly installed — if it cannot detect the filter the dryer will stop working to prevent lint from entering the drum or exhaust system. This is easy to fix by simply removing and reinserting the lint filter correctly. If the error persists after reinserting the filter the sensor may need professional inspection.

Common causes

  • Lint filter was not pushed all the way into the filter housing after cleaning
  • Lint filter was accidentally left out after a cleaning session
  • Filter is inserted at an angle and not sitting flush in the housing
  • Filter sensor has malfunctioned and is not detecting a correctly inserted filter

How to fix it

  1. 1

    Remove the lint filter completely from its housing

  2. 2

    Check the filter for any damage or excessive lint buildup and clean if needed

  3. 3

    Reinsert the lint filter firmly and make sure it sits flush and fully in the housing

  4. 4

    Restart the dryer and check if the Filter Out message has cleared

  5. 5

    If the error keeps appearing after correctly reinserting the filter the unit needs a professional repair
