Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Grinder is difficult to turn. | Grind setting is too fine, or burrs are obstructed by foreign objects or excessive coffee oils. | Adjust to a coarser grind setting. Disassemble and clean the burrs thoroughly. |
| Inconsistent grind size. | Burrs are not properly seated, or grind setting is loose. | Ensure burrs are correctly assembled and the grind adjustment knob is tightened to the desired setting. Clean burrs to remove any buildup. |
| Grinder produces a squeaking sound. | Friction between moving parts, possibly due to lack of lubrication or debris. | Disassemble and clean all moving parts. Ensure no debris is caught. No lubrication is typically required for ceramic burrs. |
