Cleaning and maintenance

Before cleaning or maintenance, always turn the appliance off,
unplug from the mains socket and leave to cool.
Cleaning the milk frother
The milk frother must be cleaned each time you use it. Proceed as
follows:
• Remove the milk container by pressing the "PRESS" lever and at
the same time pulling upwards: wash with hot water.
• Remove the red frother by pressing on the clip (A) and at the
same time pulling upwards (fig. 14).Remove the rubber mixer,
wash and clean with hot water, particularly the four holes indi-
cated in figure 15 (use a needle). Make sure the hole indicated
with the arrow B is not blocked.
• Once clean, all elements must be replaced correctly. In particu-
lar, make sure the rubber mixer is inserted completely and that
the red frother is pushed in fully until it clicks into place.
Important: to help clean the milk tube, use the tube
brush provided.
If you do not clean the tube after use, milk frothing may not be
successful, the milk may not be sucked up or milk may drip
from the milk tube.
Other cleaning
• Also clean the carafe, filter holder and permanent filter regular-
ly.
• When cleaning plastic parts of the appliance, do not use sol-
vents or abrasive detergents. Clean with a soft damp cloth only.
• Remove the drip tray, empty and wash regularly.
• NEVER emerge the appliance in water.

Descaling

Over time, calcium in the water may build up and cause blockages,
reducing the efficiency of the coffee machine and increasing the
time required to make the coffee.
Formation of scale depends on the hardness of the water and on
how often the coffee machine is used.To obtain optimum perform-
ance, the appliance should be descaled regularly.
The machine should therefore be descaled at least every 40 cycles.
To descale, proceed as follows.
• extract the chlorine filter and the permanent filter (to avoid
contamination);
• fill the carafe with four cups of water;
• dissolve two spoonfuls (about 30 grams) of citric acid (available
from chemists or drug stores) and pour the solution into the
water tank;
• place the carafe on the hot plate and the filter holder without
ground coffee;
