cappuccino and the other.
• Attention: after the last capppuccino has been
prepared, before turning off the coffee maker,
lift the suction tube of the milk tank above the
level of any remaining milk (as indicated in fig.
27) and allow the steam to come out for a few
seconds. With the tube extracted from the
remaning milk close the steam knob. For
reasons of hygiene, it is recommended that
this operation always be carried out so as to
prevent any milk from going sour in the
internal circuits of the coffee maker.

CLEANING AND MAINTENANCE

• Before beginning any cleaning or maintenance
operation, turn the machine off, remove the
plug from the electrical power source and let
the machine cool down.

CLEANING THE MILK FROTHER

The cleaning operations for the milk frother must
be done after each use. Proceed as follows:
• Remove the milk tank by pressing the (C) lever
(fig. 30), pulling upwards at the same time.
Wash it with hot water.
• Remove the red milk frothing instrument by
pressing down on lever (A) and at the same
time, pulling upwards (fig. 30). Remove the
rubber mixer, rinse it and clean it thoroughly
with hot water, with special attention paid to

the
following
the four holes illustrated in figure 31 (clean
them with the use of a needle).
Make sure that the hole marked with the arrow
B has not been clogged (clean it with the use of
a needle).
• Once clean, all of the pieces must be
reassembled in the correct order. In particular,
make sure that the rubber mixer has been
inserted properly all the way down and that
the milk tank and the red milk frother have
been inserted all the way until a click is heard.
If this cleaning procedure is not performed after
every use, the milk may not froth properly or it
may happen that milk is either not drawn up
properly or drips from the milk tube.

OTHER CLEANING PROCEDURES

• To clean the machine, do not use solvents or
abrasive detergents. A soft damp cloth should
be used to clean the surfaces.
• Regularly clean the filter holder, the drip
collection pan, the hot water drip spout, and
the coffee pots. Do not wash the filter holder
in the dish washer.
• Never immerse the machine in water: it is an
electrical appliance.
• Check from time to time that the holes in the
filter for espresso coffee are not obstructed. If
necessary, carefully clean the filter with hot
water, scrubbing with an abrasive pad.

DESCALING

If the water in your area is quite hard, the lime
from this water can accumulate with the passage
of time. Lime deposits can compromise the proper
functioning of the appliance.
The espresso coffee machine must be decalcified
every 1 to 3 months (depending on the hardness of
the water and the frequency of use) using white
wine vinegar. Proceed as follows:
• Fill the coffee pot for espresso coffee with
vinegar to level 4 (WATER LEVEL side);
• Pour the vinegar into the hot water tank and
replace the plug;
• Attach the filter holder;
• Place the small coffee pot under the filter
holder;
