Vent maintenance isn’t just about drying performance — restricted airflow is one of the leading causes of home dryer fires nationally. Here’s how to stay ahead of it on a Miele dryer.
Clean the Lint Trap Every Load
This is the easiest and most important habit: remove visible lint before every single load, not just when it looks full. A thin, hard-to-see film of lint can still meaningfully restrict airflow.
Inspect the Exterior Vent Quarterly
Check that the exterior vent flap opens freely when the dryer is running. A flap that opens only partially is a strong sign of a blockage further down the duct.
Schedule a Full Vent Cleaning Annually
Lint accumulates inside the duct run itself well beyond what the lint trap catches. A full annual vent cleaning is one of the most effective ways to prevent overheating faults from recurring.
Warning Signs Between Cleanings
Clothes taking longer than usual, the exterior of the dryer feeling unusually hot, or a burning smell are all reasons to book a dryer inspection right away rather than waiting for the annual cleaning.
