What Does Error E01 Mean?
The Bosch dryer error E01 indicates a blockage in the lint filter area or airflow path, leading to a malfunction in the heating element. This typically prevents the dryer from starting or completing a drying cycle. Symptoms include the E01 error code on the control panel, reduced airflow, and overheating warnings due to lint accumulation. Regular maintenance, such as cleaning the lint filter and inspecting the heat exchanger, is essential to prevent this issue.
Common Symptoms:
- Error code E01 displayed on the dryer control panel
- Drying cycle will not start or stops due to a detected blockage
- Reduced airflow or overheating warning due to lint blockage
Possible Causes
- Clogged lint/fluff filter (high)
- Blockage around filter area or in heat exchanger (high)

DIY Fix Clean the lint/fluff filter
- Turn off the dryer and open the door.
- Remove the lint/fluff filter from the designated slot.
