Decalcification:
In areas with particularly hard water the
machine may not operate optimally. Decalcify
the machine approximately every 2 months
(depending on the frequency of use and the
hardness of the water) using the special anti-
scaling powder.
Important:
This procedure must only be
performed when the machine is cold and has
not been recently used.
1. Make sure that the main power switch (1) is
in the "O" (off) position.
2. Remove the water tank (6) and empty it.
3. Unscrew the
(counterclockwise) and empty the boiler (12)
by turning the machine upside down.
4. Remove the shower plate (17) and clean it.
5. Prepare a solution of approximately 1.8
liters of water mixed with one packet of
powdered anti-scaling agent.
Fill the boiler (12) with enough solution to
reach the ¾ mark (approx. 0.8 lit.) on the
water level indicator (23). Replace and
tighten (clockwise) the boiler cap (4) and
make sure the steam knob (7) is also tightly
closed (clockwise). Pour the rest of the
solution (approx. 1 liter) into the water tank
(6) and replace the tank in the machine.
6. Turn the main switch (1) to the "I" (on)
position. The red ON light will light up. Wait
until the green ready light (3) lights up.
Slowly open (counterclockwise) the steam
knob (7) to discharge the "false pressure"
due to the air remaining in the boiler. Close
the steam knob (clockwise) slowly and wait
for the green light (3) to come on.
7. Place an empty cup under the coffee group
(14) without installing the portafilter (9).
Raise and lower the coffee lever (2) until it
stops. Repeat this operation until the cup is
full of water. Leave the machine on and wait
20 minutes.
8. At this point, work the coffee lever (2) until
all the solution in the water tank (6) has
been pumped out. Rinse the water tank (6)
boiler cap (4)
• 15 •
thoroughly and refill it with clean water.
Once again, using the lever, pump water
through the machine until the tank is empty.
9. Turn the main switch (1) to the "O" (on)
position. Slowly open (counterclockwise) the
steam knob (7) and wait until all residual
steam has been released from the steam
nozzle (8). Remove the boiler cap (4), empty
the boiler (12) and rinse thoroughly with
fresh water. Reinstall the shower plate (17).
