Machine displays 'Fill beans' or similar message even though the bean container is full.

Safety first: Unplug the machine before reaching into the bean container.

• Stir beans: Gently stir the beans in the hopper to break up any bridges that prevent beans from falling into the grinder.
• Change beans: Avoid very oily or flavored beans. Use medium-roast beans recommended for fully automatic machines.
• Empty and clean hopper: Remove all beans and vacuum out old oils and dust. Refill with fresh beans.
• If message persists: The grinder load sensor or detection algorithm may be faulty. Professional diagnosis is required.
