Machine displays E11; often associated with milk carafe or cappuccinatore not functioning correctly.

Safety first: Unplug the machine and ensure all parts are cool before disassembling the milk system.

Step-by-step checks:

• Disassemble milk system: Remove the milk carafe or cappuccinatore. Take apart all removable components (nozzles, suction tubes, air intake parts).
• Clean thoroughly: Soak parts in warm water with a food-safe detergent, then rinse well. Use the supplied brush to clean narrow passages.
• Run milk cleaning program: If your Saeco model has a dedicated milk cleaning cycle, run it with water and a milk system cleaner.
• Reattach correctly: Ensure the milk carafe is fully inserted and locked. Misalignment can prevent sensor detection.

When to call a technician: If E11 persists after cleaning and correct assembly, the milk valve or sensor may be defective and should be serviced professionally.
