5. Care and Maintenance
5.1 Cleaning
Regular cleaning ensures optimal performance and longevity of your grinder.
- Daily Cleaning: After each use, tap the powder tray to remove any residual grounds. Use a brush to clean the burrs and hopper.
- Deep Cleaning: Periodically, disassemble the grinder completely. Wash the lid, hopper, body, and powder tray with warm soapy water. Rinse thoroughly and dry completely before reassembly. The stainless steel burr assembly should be cleaned with a dry brush or cloth; avoid water to prevent rust or damage to internal mechanisms.

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Grinder is difficult to turn. | Grind setting is too fine; beans are jammed; burrs are dirty. | Adjust to a coarser setting. Check for foreign objects. Clean the burrs. |
| Inconsistent grind size. | Burr assembly not properly secured; burrs are worn; grind setting too coarse for desired consistency. | Ensure all parts are assembled correctly. Clean burrs. Adjust grind setting. |
| Ground coffee sticks to the powder tray. | Static electricity. | Lightly tap the tray before opening. A small amount of moisture (e.g., a single drop of water on the beans before grinding) can reduce static. |
| Handle detaches during grinding. | Handle not fully seated on the shaft. | Ensure the handle is pushed down firmly onto the hexagonal shaft until it clicks or is fully seated. |
