6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inconsistent Grind Size | Burr adjustment not set correctly or burrs are dirty. | Ensure the grind adjustment dial is set to the desired click. Clean the burrs thoroughly to remove any lodged particles. |
| Grinder is Hard to Turn | Grind setting is too fine for the beans, or beans are very hard. | Adjust to a coarser setting. If using very light roast beans, they can be denser; try a slightly coarser setting or a different bean. |
| Coffee Grounds Sticking (Static) | Static electricity buildup, especially with dry beans or in dry environments. | Lightly mist beans with water before grinding (Ross Droplet Technique). Tap the grinder gently after grinding to dislodge grounds. |
| Handle Falls Off Easily | Handle not fully seated or tightened. | Ensure the handle is pushed down firmly onto the shaft and the retaining screw (if applicable) is tightened. |
