Ascaso machine's grinder runs but does not grind beans effectively (beans bounce, little coffee output).

User checks:

• Check hopper gate: Ensure the bean hopper outlet is open.
• Adjust grind setting: Move to a slightly coarser setting and test.

Maintenance:

• Clean grinder: Empty hopper, vacuum out old grounds, and remove upper burr to clean the grinding chamber.
• Inspect burrs: If burr edges are dull or chipped, replace the burr set with the correct Ascaso burrs.
• Check alignment: Reinstall burrs carefully, ensuring proper seating and alignment.
