7. Troubleshooting
If you encounter issues with your BRUNO Electric Coffee Maker, refer to the following common problems and solutions:
- Device not turning on or grinding: Ensure the device is fully charged. Check if the motor unit and mill unit are securely locked in place.
- Grinding is slow or inconsistent: Check if the coffee beans are too oily or if there are foreign objects in the mill. Clean the mill unit thoroughly. Ensure the grind size setting is appropriate for the beans.
- Coffee not dripping properly: Ensure the dripper is clean and not clogged. Check if the ground coffee is too fine, which can impede water flow.
- Battery not charging: Verify that the USB cable is properly connected and the power source (adapter/power bank) is functioning and provides at least DC5V/1A.
