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. Avoid operating the machine if you suspect internal leaks.
User-level checks:
- Clean coffee spouts: Use a pin or needle to clear the coffee outlet holes. Then run several rinse cycles.
- Clean brew group filter: Remove the brew group and clean the metal filter screen thoroughly with warm water and a soft brush.
- Descale: Run a full descaling cycle to clear scale from the hydraulic circuit and overpressure valve.
- Inspect drip tray: Check for excessive water in the drip tray after a single cycle, which may indicate an internal bypass or leak.
When to call a technician: If E09 persists or you see water under the machine, an internal hose, O-ring, or overpressure valve may be faulty and should be replaced by a professional.
