Cleaning and maintenance - Descaling
every time you fill the coffee bean
container or, in any case, at least once
a week.
Turn off the machine and pull out the
plug.
Remove the dregs box (
1
) and drip
tray (
2
), then open the service door (
13
).
Take out the dispensing unit (
14
),
holding it by the handle and pushing the
PRESS button. Use hot water only,
without detergents
,
to clean the
dispensing unit.
Make sure that there are no coffee
residues on the two steel filters. You may
remove the upper filter by unscrewing
the plastic pin with the wrench provided.
Thoroughly wash and dry all the parts
of the dispensing unit.
Replace the filter and use the wrench
provided to tighten the plastic pin firmly
into place.
Thoroughly clean the machine
compartment.
Holding the dispensing unit by its
handle, fit it back securely into place
inside the compartment.
Then close the door and set the dregs
box and drip tray back into place.

DESCALING
Descaling is necessary to remove lime
scale from all surfaces and holes, thus
ensuring a perfect operation of valves,
heating controls and other important
parts.
Note: due to the complexity of the
coffee machine hydraulic circuit,
the following descaling cycles
(automatic and standard) do not allow
the descaling of tubes.
In fact, easily accessible components
such as the central unit (14) and its
plastic connection are excluded.
The machine must be descaled every 3-4
months, according to the water hardness
degree. A more frequent descaling is
recommended wherever the water
hardness degree is very high.
In case of hard water, a filter should be
used both to improve the coffee quality and
to protect the machine, thus reducing the
descaling frequency.
Note: for this purpose, use a
descaling product suitable for
coffee machines. Never use vinegar to
clean the machine; it might damage it.
To facilitate the above operation, the
machine displays a message whenever it
needs descaling:
d e c a l c i f y
r e a d y f o r u s e
The machine will continue to dispense
coffee, but should be descaled as soon as
possible.
Descaling may be performed either
manually or automatically by the machine
itself.

Conventional descaling
With the machine off, mix the descaling
solution in the water container in a
proportion of 1:1, following the
directions on the package.
Place a container under the steam/hot
water tube (5) and slowly turn the steam/
hot water knob (6) counterclockwise.
Press the main power switch to turn on
the machine and dispense approx. 3 dl
of descaling solution through the nozzle.
Set the knob (6) back in the initial
position. Again press the main switch to
turn off the machine and allow the
solution to act for approx. 5 minutes.
