Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the washer. Do not force the door open with tools as this can damage the lock and seal.
Steps to check and address E42:
- Wait and check water level: Allow several minutes after cycle end. If water remains in the drum, run a drain program (if possible) or manually drain via pump filter.
- Use emergency release: Many Siemens models have a manual door release near the pump filter. Open the lower flap and pull the colored tab or cord to unlock the door.
- Inspect and replace lock: Once open and power is off, access the door lock behind the front panel/door seal and replace if it is mechanically or electrically faulty.
When to call a technician: If the door remains locked even with emergency release, or if the front panel must be removed, professional service is recommended.
