2) Cleaning filters
- Put 2 or 3 teaspoons of detergent powder
for coffee machines in about 1/2 a litre
of water inside a heat-resistant container
and boil.
- Dip filters in the boiled solution and
leave them fully submerged for about 30
minutes.
- Rinse thoroughly with clean water and
run hot water through one group several
times with the filters in place.
- Make one cup of coffee and discard in
order to remove any unpleasant flavor.
3) Cleaning filter holders (portafilters)
Using the proper cleaning tool (brush)
wash the filter holders under hot water,
a neutral detergent may also be used.For
extraordinary cleaning see the Portafilter
Manual.
4) Cleaning the drain collector
Remove the drain tray grill at least twice
a week and clean, pull out the water drain
collector and clean it thoroughly. Inspect
and clean also the drain box and remove
any leftover grounds.
5) Cleaning the body
Wipe the stainless steel surfaces with a
soft, non abrasive cloth in the direction of
the glazing marks, if any. Do not use any
alcohol or solvents whatsoever on painted
or imprinted parts in order not to damage
them.
6) Cleaning the hot water and steam nozzles
Steam nozzles must be cleaned
immediately after use with a damp cloth
and by producing a short burst of steam
so as to prevent the formation of deposits
inside the nozzles themselves, which
may alter the flavor of other drinks to
be heated. Hot water nozzles must be
cleaned periodically with a damp cloth.
7) Cleaning the diffuser screen
- Due to filter holder discharge operations
(subsequent to coffee brewing), a certain
amount of coffee grounds may slowly
build-up on and obstruct, even partially,
the diffuser screen. To clean it, you must
first remove it by unscrewing the diffuser
screw.
- Put 2 or 3 teaspoons of cleaning
detergent for coffee machines in about
1/2 a litre of water inside a heat-resistant
container and boil.
- Place the diffuser screen(s) and diffuser
screw(s) in the solution and leave them
fully submerged for about 30 minutes.
Rinse thoroughly with clean water. Install
and run hot water through each group
several times with the screen installed.
8) Water Filter/Softener
Please see the documentation accompanying
the water filter/softener for proper operating
and cleaning instructions.
• Steam boiler draining: to activate this function
you need to access the programming menu
(see p. 93). Yearly, we recommend to fully
drain the steam boiler by means of the
specific drain cock located on the side of
the boiler or under the boiler.
9) Depressurize the steam boiler
Press and hold the encoder knob to set
the espresso machine to “OFF”, then
push down the steam lever in order to
depressurize the steam boiler.
IMPORTANT
If the machine has not been used for more
than 8 hours or, in any case, after long
periods of being idle, in order to use the
machine to its full potential it is necessary
to perform some cleaning cycles before
brewing beverages as follows:
- Groups: with the portafilters engaged
in the groups brew water through each for
at least two minutes
- Being careful to avoid burns, turn on
