The “clean lint filter” light is a reminder, or on some models an airflow warning, that the lint screen needs cleaning. Clean the screen, push it in fully, and the light usually goes out when the next cycle starts. If it stays on, the screen may be coated, or the vent may be restricted.
Key takeaways
- It is a reminder or an airflow warning, depending on the model.
- Clean the screen after every load, and wash it now and then.
- A light that stays on after cleaning points to a coated screen or a restricted vent.
- Restricted airflow is a fire risk, so do not ignore a light that keeps coming back.
What the light means
| When it comes on | What it usually means | What to do |
|---|---|---|
| At the end of every cycle, or after each load | A simple reminder | Clean the screen, then continue |
| Part-way through a cycle, or the cycle runs long | An airflow warning: the screen or the vent is restricted | Clean the screen, and run the vent test |
| Immediately after you cleaned the screen | The screen is not seated, or the light has not reset | Push the screen in fully, and start a cycle |
| It keeps coming back | A coated screen or a restricted vent | Wash the screen, and clear the vent |
What does the clean lint filter light mean?
It is a reminder, or on some models an airflow warning, that the lint screen needs cleaning. Clean the screen, push it in fully, and start a cycle. On many dryers the light clears by itself. If it keeps coming back, the screen is coated or the vent is restricted.
How to clear it
- Pull out the lint screen and remove the lint.
- Rinse the screen under warm water with a little dish soap, and scrub the mesh. Softener film can block it even when it looks clean.
- Dry the screen completely, then push it in fully.
- Check the lint housing with a flashlight and clear any lint you can reach.
- Start a cycle. If your manual says so, press the reset button or open and close the door.
Why is my lint filter light still on after cleaning?
The screen may not be seated, the mesh may be coated with softener film, or lint may be in the housing. A restricted vent can also keep an airflow warning on. Wash the screen, push it in fully, run the 10-minute vent test, and check the manual for a reset step.
When it points to a vent problem
If the light comes on mid-cycle, drying takes longer than it used to, or the dryer feels very hot, the vent is likely restricted. That is a fire risk as well as an inconvenience. See the vent safety guide, how to clean a dryer vent and the vent cleaning page.
Is the lint filter light a serious problem?
Not by itself. It is a prompt to clean the screen. But a light that keeps returning after cleaning can mean restricted airflow, which overheats the dryer and raises the fire risk. Treat a recurring light as a reason to check the vent.

Frequently asked questions
How often should I clean the lint screen?
After every load. Wash it with soap and water now and then.
Does every dryer have this light?
No. Many dryers have a lint reminder, and some use an airflow sensor. Check your manual.
Can I ignore the light if drying seems fine?
Clean the screen anyway. A clean screen is the cheapest safety habit. If the light returns quickly, check the vent.
What does it mean if the light is on and the dryer is hot?
Likely restricted airflow. Stop the dryer, let it cool, and clear the screen and the vent before using it again.
