- MAINTENANCE
Maintenance opera-
tions must be carried
out when the machine
is off and cold. Some
particular operations
must be performed
when the machine is
operating.
Do not clean the machine by using metal
or abrasive devices, such as steel wool,
metal brushes, needles, etc. or general
detergents (alcohol, solvents, etc.)
When necessary, use special detergents
for coffee machines that can be pur-
chased in specialised service centres.
Keeping your machine clean will prolong
its life and produce better espresso bev-
erages.
8.1 Cleaning the steam
wand
1. Clean the steam wand after every use
by wiping with a damp cloth. Turn the
steam wand on to release condensation
and milk residue.
2. If the steam jets become clogged with
the powdered milk, unscrew the noz-
zle and unlock/clean with a paper clip
(fig._8.1).
8.2 Cleaning
the dispensing head
BACKFLUSHING
1. Remove the filter basket from the porta-
filter and fit the blind filter (A - fig_8.2).
2. While the brew water is flowing loosely
insert the portafilter into the unit head,
rotating the portafilter back and forth
(B -
fig_8.2).
Keep emptying the blind
basket of hot water until the water runs
clear.
3. Backflush the unit head every day.

a small amount of espresso cleaning

gent is available from every authorised
dealer.
