E10 appears and the machine stops mid-brew; sometimes accompanied by low water flow and gurgling sounds.

Safety first: Unplug the machine and allow it to cool if it has overheated.

Steps:

• Refill tank: Ensure the water tank is full and properly seated.
• Prime the system: Open the steam/hot water valve (if fitted) and run a hot water cycle to purge air from the boiler until a steady stream flows.
• Clean inlet filter: Check the small mesh filter at the tank outlet or machine inlet for debris. Rinse thoroughly.
• Descale: Run a full descaling cycle to remove scale that may be trapping air pockets.

Note: If E10 recurs frequently even with a full tank and after descaling, the low-water detection (flow meter or sensor) may be faulty and require replacement.
