Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the cooker before any disassembly. Firmware-related issues should be handled carefully.
Steps to attempt recovery:
- Power cycle: Unplug the unit for 10–15 minutes, then reconnect and check if E18 clears.
- Factory reset: If your Siemens model supports it, perform a factory reset via the settings menu (refer to the user manual). This can clear minor memory errors.
- Avoid unstable power: Connect the cooker directly to a stable wall outlet, avoiding extension cords or generators.
When to call a technician: Persistent E18 usually requires reprogramming or replacing the main control board. Contact Siemens service for model-specific procedures.
