1. Unusual Noise During Grinding

Possible Cause: Small stones in coffee beans can get into the grinder.
Solution:
- Press the ON/OFF button to stop grinding.
- To avoid stones:
  - Shake the coffee bag well to move any stones to the bottom.
  - Before adding beans from the bag’s bottom, check for any stone-like particles and remove them.

2. Low or No Coffee Grounds Output

Possible Causes:
- Clogged grinder from incomplete cleaning.
- Oil residue from dark-roast beans causing blockage.
- Using unsuitable beans (e.g., flavored, frozen, or coated).
- Switching directly from coarse to fine grind settings with beans inside.
Solution:
- Clean any buildup of grounds and oils inside the grinder, following video tutorials online if necessary.
- Use grinder cleaning tablets if available.
- For grind setting adjustments:
  - Adjust coarse-to-fine settings only when no beans are in the grinder, or finish grinding before changing settings.
