Possible Causes
How to Fix / Troubleshooting
Safety: Unplug the machine. Do not force the brew head by hand; you can damage gears.
User checks:
- Remove portafilter or brew basket: Ensure nothing is obstructing the brew head path.
- Clean brew area: Wipe away coffee grounds and residue around the group head and locking lugs.
- Power reset: Plug back in and power on to see if the machine can re-home the brew head.
Advanced checks:
- Open the housing to access the brew head drive motor and gear train.
- Inspect for broken or stripped plastic gears and obstructions in the carriage rails.
- Check the position sensor or limit switches for proper actuation and secure wiring.
Resolution: Clear any obstructions and lubricate rails lightly with food-safe lubricant. Replace damaged gears, the brew head drive motor, or faulty position sensors as needed. If ER08 persists after mechanical repair, the control board may require replacement.
