Safety Warning

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the machine and allow it to cool for at least 30 minutes before any inspection. Hot internal parts can cause burns.
User-level checks:
- Descale the machine: Heavy scale can cause overheating and sensor errors. Run a full descaling cycle with Saeco-approved descaler following the on-screen instructions.
- Check ventilation: Ensure the machine has adequate space around it and is not enclosed in a tight cabinet, which can cause overheating.
- Power cycle: After cooling and descaling, unplug for 5 minutes, then reconnect and restart the machine.
When to call a technician: If E05 reappears, the NTC sensor, thermal fuse, or heater wiring likely needs testing and replacement. These components are on the high-voltage side and should only be serviced by a qualified technician.
