5. Maintenance
5.1 Cleaning
- Wipe the exterior of the grinder body with a clean, damp cloth. Do not use abrasive cleaners.
- The transparent acrylic spice container can be hand-washed with mild soap and water. Ensure it is completely dry before refilling with spices.
- Important: Do not immerse the grinder's main body in water, as this can damage the electronic components. This product is not dishwasher safe.
5.2 Ceramic Grinding Core Care
The ceramic grinding core is designed for durability. To maintain its performance, avoid grinding extremely hard substances that could cause damage. Regular cleaning of the spice container helps prevent residue buildup around the core.
6. Troubleshooting
- Grinder Not Working or Clogged:
If the grinder does not operate or spices are not dispensing, first ensure that the 6 AAA batteries are correctly installed and have sufficient charge. If the issue persists, adjust the coarseness knob to a coarser setting. This can help clear any clogged particles within the grinding mechanism. - Inconsistent Grind:
Verify that the coarseness adjustment knob is set to your desired level. Ensure the spice container is not overfilled, which can sometimes affect grinding consistency. - Blue LED Light Not Illuminating:
Check the battery installation and charge. The LED light should activate automatically when the grinder is tilted for operation.
