Display shows E08; machine may grind beans but no coffee is dispensed, or pucks are very thin and watery.

Safety first: Turn off and unplug the machine before cleaning the grinder or coffee chute.

Step-by-step checks:

• Clean coffee chute: Open the service door and locate the coffee chute (often near the pre-ground coffee compartment). Use the supplied cleaning brush or a narrow brush to remove compacted grounds.
• Adjust grind setting: Set the grinder slightly coarser to reduce fines that can clog the chute. Only adjust while the grinder is running.
• Check bean quality: Use fresh, medium-roast beans. Very oily or flavored beans can cause clogs and dosing errors.
• Reset coffee strength: Reduce the coffee strength setting and test. Excessive dose can overload the brew group.

When to call a technician: If E08 persists and pucks are inconsistent, the grinder burrs or dose sensor may need calibration or replacement by a technician.
