Descale Instructions for the De'Longhi Magnifica 3300

De'Longhi is a small appliance manufacturer based in Treviso, Italy. The ESAM3300 Magnifica Super-Automatic Espresso/Coffee Machine features a built-in coffee bean grinder, a height-adjusting coffee spigot to accommodate all sizes of cups, a heated cup tray and an instant reheat function that keeps the machine at a particular temperature between brewing cycles. Because the machine holds heated water for long periods of time, lime scale deposits start to appear after extended use. The decalcification warning light indicates when it is time to descale your espresso maker.
