Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Grinder does not start | Not plugged in; power outage; hopper not correctly assembled. | Ensure power cord is securely plugged in. Check power supply. Reassemble hopper correctly until it clicks into place. |
| Inconsistent grind | Burrs are dirty or worn; incorrect grind setting for bean type. | Clean burrs thoroughly. Adjust grind setting as needed. Consider replacing burrs if heavily worn (contact support). |
| Grinder clogs or stops during operation | Too many beans; fine grind setting for oily beans; burrs are clogged. | Reduce amount of beans. Try a slightly coarser grind setting. Clean burrs and grinding chamber using the knock tool. |
| Excessive static cling of grounds | Dry beans; environmental humidity. | The grinder has anti-static technology, but some static may occur. Lightly misting beans with water before grinding can help. Ensure the anti-static needle in the spout is clean. |
