Possible Causes
Child lock enabled, Faulty start button on control panel, Door not detected as closed, Defective user interface board
How to Fix / Troubleshooting
Safety first: Disconnect power before removing the control panel.
- Check child lock: Refer to the SMEG user manual to see if a key lock or child lock is active (often indicated by a padlock symbol). Disable it using the specified button combination.
- Verify door closure: Ensure the door is fully closed and latching correctly. Listen for the click of the door lock.
- Test other buttons: If some buttons work and others do not, the keypad or touch panel may be faulty.
- Inspect UI board: Remove the inner door panel to access the user interface PCB. Check for moisture, corrosion, or loose ribbon cables.
- Replace UI module if needed: If the start button circuit is defective, replace the user interface board or complete control panel assembly.
