• Scale (calcium carbonate) is a harmless natural mineral contained in water that may
deposit and create a thin solid coating on the inner walls of the boiler.
If you see that scale is forming, clean the boiler with a mixture of water and vinegar.
To eliminate the scale, pour a mixture of 50% water and 50% white vinegar into the
boiler. Do not insert the funnel. Close the espresso maker and place it on the power
supply base.
Let the espresso maker heat for a maximum of one minute, then remove it from the power
supply base and place it on a flat surface for a few hours (all night is recommended). Then
open the espresso maker, pour out the liquid and eliminate the remaining scale by rinsing
several times (fig. 19).
After this, run the espresso maker a few times filled with just water to remove any
residues of the water/vinegar mixture, which could alter the coffee's taste.
