5. Pull One Shot and Observe Extraction
Let one espresso fully extract.
Check extraction time:
Target range: 20–30 seconds
Visual check:
• Thin stream at the start
• Steady, thread-like flow in the middle
• Slow tapering at the end

6. Fine-Tune Based on Result (1 click at a time)
• Extraction finishes under 15 seconds
→ 🔧 [Solution]
Turn dial one step finer (3 → 2)
• Coffee barely flows or machine gets loud
→ 🔧 [Solution]
Turn dial one step coarser (3 → 4)
Adjust → Pull 1 shot → Evaluate
→ 🔧 [Solution]
Turn dial one step finer (3 → 2)
• Coffee barely flows or machine gets loud
→ 🔧 [Solution]
Turn dial one step coarser (3 → 4)
Always follow this order:
7. Lock in the Final Reference Setting
Once extraction is stable, keep this number as the default.
Do not adjust again unless you change beans.
Do not adjust again unless you change beans.
Changing coffee beans requires running this routine again from Step 1.
8. Failure Symptoms and Immediate Fixes
• Coffee tastes consistently weak
→ 🔧 Grind too coarse, reduce number
• Loud humming and blocked extraction
→ ⚠️ Grind too fine, increase number immediately
• Watery, muddy puck in the grounds container
→ 🔧 Unstable extraction, go 1 step finer and retry
[Caution]
The grinder dial must only be adjusted while grinding is active.
Forcing the dial while stopped can break internal plastic gears.
Gear damage requires full grinder replacement.
