Separate a recipe problem from a carafe problem by starting with fresh refrigerator-cold milk at the marked level. The carafe lid, intake tube, adjustment control and outlet must be assembled exactly as shown. A Clean rinse after each milk use prevents dried proteins from narrowing the air and milk passages that create foam.
Follow the checks in order and change only one condition at a time. Run a short rinse or test after each action, so the result identifies the cause instead of hiding it. The procedures below stay within the cleaning, refitting and user-menu operations described by the manufacturer.
Before checking De’Longhi Coffee machine
- Switch the machine off, unplug it and let hot-water, steam and metal parts cool before removing or cleaning a component. Never open the casing.
