Can I fix this myself?

Yes, this is routine maintenance rather than a repair. Follow the steps above using the consumable the manufacturer specifies, and if the message returns immediately after a correctly completed cycle, treat it as a service call.

Where do these steps come from?

They are transcribed from De'Longhi Coffee Machines Help Center — Eletta Cappuccino Evo. We do not repair machines and we do not publish a fix we cannot cite to the manufacturer.

Will this code clear on its own?

Maintenance prompts clear when the cycle they are asking for is completed in full — stopping partway usually leaves the counter running. Fault codes clear when the underlying condition is corrected, not by power-cycling past them.

Likely causes, most likely first

When to stop and call a technician

The machine trips a breaker, smells of burning, or shows scorched wiring.
Water is leaking from inside the chassis rather than from the tank, tray or portafilter.
The fault involves the boiler, a pressure valve, the heating element or the pump itself.
The code returns immediately after a correctly completed reset or maintenance cycle.
The machine is under warranty — opening it yourself usually ends that cover.

Never bypass, disable or remove a safety device — a thermal fuse, pressure relief valve or lid interlock is the part standing between a fault and a fire. Do not open a pressurised boiler or work on mains wiring.

What the fix needs

Water filter
A filter slows how fast scale returns after the fix. It does not replace descaling.
