Magnifica S: Descaling and Cleaning

How to Descale Your De’Longhi Magnifica S ECAM 22.110 Coffee Machine?

Your Magnifica S, require regular cleaning and descaling to maintain it in perfect condition, but don’t worry! The machine tells you when it’s time to descale it by lighting up the “Descale” button under the control panel (Red light blinking ).

The descaling procedure takes around 45 minutes to complete, so be sure to have enough time to finish the process. We highly recommend using our descaling solution EcoDecalk.


It is important to use De’Longhi descaler only. Using an unsuitable descaler and/or performing descaling incorrectly may result in faults not covered by the manufacturer's guarantee.
