Display shows E02 and brewing stops; pump can be heard but little or no water exits the group head.

Safety first: Turn the machine OFF, unplug it, and allow it to cool before disassembling any parts.

• Remove and clean brew group (if removable model): Open the service door, slide out the brew group assembly, and rinse it thoroughly under warm water. Use a soft brush to clean the coffee screen and moving parts. Let it dry and reinstall.
• Clean coffee spouts: Remove the front coffee spout assembly if possible. Soak it in warm water with mild detergent, then flush from both directions to clear coffee oils and fines.
• Run descaling cycle: Use SMEG-approved descaler and run a full descaling program according to the user manual. This helps clear scale from the hydraulic circuit and overpressure valve.
• Check coffee grind: If using an integrated grinder, adjust to a slightly coarser grind. If using ground coffee, avoid very fine espresso powder that can choke the system.
• Inspect overpressure valve (advanced): With the cover removed (only if you are qualified), locate the overpressure valve on the pump outlet. Check for scale or blockage and replace if leaking or stuck.
• If E02 remains: The internal hydraulic circuit may be severely blocked or the overpressure valve/pump may be failing. Contact SMEG service for professional repair.
