Can I fix this myself?

Yes. This is a user-serviceable condition and the steps above are the ones the manufacturer publishes. If it returns straight after you complete them, stop and book service.

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 We do not repair machines and we do not publish a fix we cannot cite to the manufacturer.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.

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.
