Routine Overview
A routine for optimizing extraction by adjusting the grinder when coffee flows too quickly (sour taste) or too slowly (bitter taste).
Delonghi machines can ONLY be adjusted while the grinder is running!
Adjusting while stopped risks damaging the grinder.

1. Diagnose Current Status
Identify issues with your recent coffee extractions:
- Extraction under 25 seconds → Grind too coarse
- Over 40 seconds or dripping → Grind too fine
- No/weak crema → Grind too coarse
- Extraction under 25 seconds → Grind too coarse

Adjust only one click at a time. Avoid excessive adjustment!
6. Test Extraction
After adjustment, discard the first two shots.
This clears old grounds and allows new setting to take effect.
