Possible Causes
Corrupted configuration memory on main control board, failed EEPROM chip, incomplete software update, severe power fluctuation
How to Fix / Troubleshooting
Safety first: Turn off power at the mains before handling the control board.
- Power cycle: Disconnect power for 10–15 minutes, then restore. Sometimes the board will reinitialize and clear minor memory errors.
- Check supply stability: Ensure the oven is on a dedicated circuit with proper voltage. Correct any loose wiring at the terminal block.
- Factory reset: Some Smeg models allow a service-level reset via a key combination. Refer to service documentation if available. Do not attempt undocumented procedures.
- Board replacement: If Er15 persists, the EEPROM or microcontroller on the main control board is likely damaged. Replace the entire main control board with a pre-programmed Smeg module.
