•Stop the appliance by pressing the start/stop switch (4) and wait for 10 - 15 minutes to allow the descaler to take effect.

•Next, start the machine again (4) and allow the rest of the liquid to run through by

pressing the coffee button (10) as many times as necessary.

•Then rinse with two water tanks of fresh water, clean the brewing head and replace the grid on the head of the appliance (see paragraph on maintenance).

•The guarantee does not include espresso machines which do not function, or do not function properly, because descaling has not been carried out.
