Bosch Dryer Error Code E02 — Lint Filter Needs Cleaning
What this means
Error E02 indicates the dryer has detected restricted airflow due to a dirty lint filter. When the filter is clogged, the dryer cannot properly circulate hot air, reducing drying performance and potentially causing overheating. This is one of the most common and easiest dryer issues to fix.
Step-by-step fix
4 stepsRemove and clean the lint filter
Pull out the lint filter (usually located inside the door opening or on the top of the dryer) and remove all lint.
Clean the filter before or after every load to prevent this error.
Wash the filter if needed
If fabric softener residue has built up, wash the filter with warm soapy water and let it dry completely before reinstalling.
Hold the filter under running water — if water pools instead of flowing through, the filter needs washing.
Vacuum the filter housing
Use a vacuum with a narrow attachment to clean lint from inside the filter slot.
Restart the dryer
Reinsert the filter and restart the drying cycle.
When to call a professional
No professional service is needed for this error. If it persists after thorough cleaning, the airflow sensor may be faulty.
