Troubleshooting
- Grinder feels stiff or difficult to turn: Check if the grind setting is too fine. Adjust to a coarser setting. Ensure no large debris is caught in the burrs.
- Uneven grind: Ensure the burrs are clean and free of old coffee residue. Consistent rotation speed during grinding can also help.
- Static cling of grounds: A very small amount of water (a single drop) can be added to the whole beans before grinding to reduce static.
