What should I do if it shows an error (e.g., Error 4)?
Common causes:
- Temperature sensor issue
- Low gas pressure or supply
- Ventilation problem (gas units)
- Overheating protection activated
👉 Error codes are safety indicators, not random faults.
What to do:
- Turn off the unit
- Wait a few seconds
- Restart
If the error persists → contact authorized service.
