Frequently Asked Questions

Bean jam, worn burrs, or motor issues. Remove beans and clean the burrs manually.

Basic cleaning and unjamming is safe. Burr replacement or motor repair may require professional service.

Burrs are jammed. Manually rotate to dislodge stuck beans. If still stuck, the motor may be failing.

Built-in grinders are convenient but can be limiting. A quality separate grinder often produces better results.

Every 6-12 months depending on usage. Steel burrs last longer than ceramic. Clean weekly to extend life.
