Bosch Dryer E01/E02 error code
The dryer's lint filter is blocked and needs cleaning. A clogged filter chokes airflow, so the dryer takes longer, runs hotter, and can shut itself down to protect against overheating.
Also shown as: E01, E02

What causes the E01/E02 error?
- Lint and fluff built up on the filter
- Filter not cleaned after recent cycles
- Filter coated with residue reducing airflow
How to fix Bosch E01/E02 — step by step
Work through these in order, from simplest and safest first. Stop as soon as the code clears.
- Remove and clean the lint filter
Take the filter out, discard the lint, and wash it under running water for a deeper clean. - Dry the filter fully
Let the filter dry completely before sliding it back in, so moisture does not reach the electronics. - Clean after every cycle
Bosch advises cleaning the lint filter after each drying cycle and rinsing it with warm water occasionally.
When to call a technician
- The code returns right after a thorough filter clean
- The dryer still overheats or stops mid-cycle
- You smell burning - stop the dryer and call for service
Frequently asked questions
Can a blocked lint filter break my dryer?
Yes, restricted airflow makes the dryer run hot and work harder, which is why Bosch flags it with an error instead of letting damage build up.
