LG Dryer Check Filter error code

Difficulty: Easy · Cost: $0 · Duration: 1m

Check Filter is not an error code. It is a routine reminder that appears before each drying cycle to prompt you to clean the lint filter. A clean lint filter ensures proper airflow and drying performance and reduces the risk of longer drying times and overheating. The indicator will turn off automatically once you select a cycle or press START/PAUSE — no other action is required to clear it.
