to clean.
By operating the lever, raise and lower
the piston multiple times until the water
flowing out of the siphon is clear and
contains no soap.
WARNING:
during this stage, do not release
the lever. The system cannot generate
enough back pressure to prevent
hammering, which may damage the
machine.
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
During normal usage, coffee residues may
stain the diffuser screen and the bottom
section of the piston. To clean them, you
will have to remove the diffuser screen, if
needed using a spoon handle to lever it
out. Then clean the diffuser screen with
the powder detergent; also clean the
bottom surface of the piston with a wet
(non-abrasive) sponge.
Rinse with plenty of clean water before
reinstalling the diffuser screen.
After reinstalling it and making sure that
the spring has snapped, operate the group
multiple times to rinse it.
WARNING:
if you perform the cleaning
procedure while the machine is hot, the
diffuser screen, the parts around it and the
rinsing water will be hot. Protect yourself
by wearing gloves.
8) Cleaning the pressure gauge/transducer siphon
Should you notice any operation fault in the
delivery pressure gauge or in the transducer,
it might be due to the duct being entirely
or partially obstructed by coffee residues.
In this case proceed as follows:
• Install a blind portafilter
• Unscrew the screw indicated by the arrow
• Operate the lever to carry out a flushing.
• Once the flushing is completed turn the
screw back in.
Carry out a test by brewing a coffee.
