1.Do not use solvents or abrasive cleaning products to
clean the appliance. A soft, damp cloth is sufficient.
2.Clean the filter holder, filters, drip tray and water
tank regularly.
IMPORTANT: during cleaning, never immerse the

DESCALING
You must descale the coffee machine about every 200
coffees.
Use the descaler provided only. To descale, proceed as
follows:
1.Fill the tank with 34 ounces (1 liter) of water;
2.Pour the contents of the descaler bottle provided
(250 ml) into the tank. For subsequent descaling
operations, descaling solution can be purchased
from authorized technical service centers.
3.Press the ON/OFF button (fig. 3) and wait for the
OK indicator light to come on.
4.Make sure the filter holder is not attached and
position a container under the boiler outlet.
5.Press the coffee button, half empty the tank and
every now and then rotate the steam knob to allow a
little of the solution to run off. Then interrupt by
pressing the coffee button again.
6.Leave the solution to work for about 15 minutes, then
run off the rest of the water in the tank.
7.To eliminate residues of the solution and scale, rinse
the water tank well, fill with clean water and replace
in its housing. Press the coffee button and operate the
appliance until the water tank is completely empty;
8.Press the coffee button again and repeat the last
operation.
Repair of damage to the espresso maker caused by
