Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug before opening the control panel. Avoid pressing keys with sharp objects.
Steps to resolve:
- Check child lock: Some Siemens models have a child lock feature. Look for a lock icon on the display and follow the manual to disable it (often by holding a specific key combination).
- Power reset: Unplug the cooker for 5–10 minutes, then reconnect and test the Start button again.
- Test other keys: If only the Start key fails while others work, the keypad membrane or switch is likely faulty.
- Inspect internal connections (advanced): Remove the control panel and reseat the keypad ribbon cable on the interface PCB.
- Replace keypad/interface: If the Start key remains unresponsive, replace the keypad membrane or user interface PCB as per Siemens parts catalog.
When to call a technician: If multiple keys fail or the panel shows signs of liquid damage, professional replacement is recommended.
