Note:
Do not perform the cleaning procedure
when other groups are dispensing coffee.
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) Cleaning the portafilter group
After pressing the straight-in release lever, it
is possible to use a non-abrasive soft cloth
to clean the portafilter support.
Do not use aggressive solvents on varnished
parts or plastic parts to avoid damage.
Clean the cover panels using a soft cloth.
Only clean with a wet cloth or with a cloth
soaked with warm water and neutral soap.
