Step-by-Step DIY Fix Guide
- SAFETY: Switch the dryer off.
- Remove the lint filter from inside the door opening.
- Peel lint from mesh by hand.
- Rinse filter under warm water if clogged.
- Allow to dry fully, then reinstall.
- Run a test cycle to confirm E02 is cleared.
If the door warning comes back
- If the door closes normally but the warning keeps returning, the latch or switch path becomes more likely than a simple alignment issue.
- If airflow still seems weak after the basic checks, the fan path or a deeper obstruction becomes more likely.
- Filter is clean but E02 persists — sensor or heating circuit inspection needed
What This Error Means
Error E02 on your Bosch dryer means: Same as E01 — the lint filter is blocked and restricting airflow. E02 is a variant of the same fault on certain Bosch dryer models. The machine's self-diagnostic system has detected this condition and stopped the current cycle to prevent further damage or unsafe operation.
The most frequent cause is lint filter not cleaned after previous cycle. Work through the causes listed below in order — starting with the simplest and most accessible.
Error E02 is DIY-safe. The fix requires no tools and typically takes under 15 minutes. Follow all steps in sequence — the most common reason this error returns is skipping the filter rinse step.
A blocked lint filter is the most preventable dryer problem. Running cycles with a clogged filter restricts airflow, forces the motor to work harder, trips thermal safety cutouts, and — in the worst case — creates a fire risk. Cleaning the filter after every cycle takes 30 seconds and prevents the majority of dryer faults.
Most Likely Cause by Symptom
The Bosch dryer may stop, pause, or refuse to complete the cycle normally.
Likely cause: Lint filter not cleaned after previous cycle
Check first: SAFETY: Switch the dryer off.
Performance may drop because airflow, filtering, or draining is restricted.
Likely cause: Lint buildup in filter housing
Check first: Remove the lint filter from inside the door opening.
Common Causes
- Lint filter not cleaned after previous cycle
- Lint buildup in filter housing
- Fine fibres embedded in filter mesh
What Not to Do
- Do not run without lint filter installed
- Do not use a torn filter
