9. MAINTENANCE
Unless otherwise speci
fi
ed, all maintenance operations
must be carried out when the machine is totally powered
down to OFF, it has cooled down and the mains socket is
unplugged. Use of metal, abrasive tools and solvents is not
recommended for machine cleaning operations:
they could all cause damages.
Where indicated, use speci
fi
c detergents for coffee machi-
nes that are available on sale in the specialised technical
service centres.
9.1 Daily maintenance
For cleaning operations use cloths or sponges that will not release
fi bres or threads.
· Clean the bodywork accurately and, on the stainless stele parts,
rub in the direction of the satin fi nish.
· Clean the steam and the hot water dispenser pipes. Check to
see that the spout diffuser nozzles are not clogged or partially
clogged with crusts and residues. If a crust removal operation is
necessary, be very careful not to deform or damage the relative
sprayer.
· Remove the fi lter baskets from the machine then remove the
fi lters and proceed with removing any coffee encrustations. To
remove grease deposits rinse out the fi lters and fi lter baskets
using hot water.
9.2 Weekly maintenance
9.2.1 Cleaning the dispensing groups
This operation must be conducted whilst the machine is operative
and under pressure.
· Place the blind fi lter on issue with the machine into the fi lter
basket. Add in a spoon of specifi c coffee machine detergent,
then reassemble the fi lter basket back into the group to be
cleaned.
· Activate the coffee dispensing start command on the group for
about 30 seconds.
In the Automatic version, once the fi lter basket is assembled
back on again, press keyboard keys 14 and 18 simultaneously.
The machine will automatically run fi ve wash cycles.
· Start up and stop the dispensing cycles for the number of ti-
mes required, until clean, clear water fl ows out of the group
discharge.
· Remove the fi lter basket, remove the blind fi lter and insert a
normal fi lter. Reassemble the fi lter basket back on and activate
the dispensing cycle for as many times as required to ensure
suffi cient rinsing.
· Make a coffee to eliminate any possible unpleasant tastes.
9.2.2 Cleaning the
fi
lters
· Prepare a cleaning solution using hot boiling water plus a packet
of the specifi c coffee machine powder detergent, in a container
that is not in aluminium or iron.
· Remove the fi lters and soak them together with the fi lter baskets
in said solution for at elast 20 minutes (if possible, all-night
soaking is preferable).
· remove the fi lters and the fi lter baskets from the detergent
solution and rinse them thoroughly under plenty of running
water.
9.2.1 Cleaning the collection tray
· Remove the cup carrier grid from the tray and clean if neces-
sary.
· Remove the discharge tray and clean it to remove any possible
encrustations and/or coffee grounds residues.
9.3 Periodic maintenance tasks
9.3.1 Water replacement and total emptying out of the
boiler
This operation must be conducted by the technical service per-
sonnel.
· Power the machine down to OFF and wait until there is no more
pressure inside the boiler (i.e. the pressure gauge must be on
“0”)
· Remove the safety valve by unscrewing it at the base using an
adjustable spanner (size 21).
· Use a pump to suck up all the water in the boiler.
· Reassemble the safety valve back on again.
· Proceed with fi lling the boiler back up again.
9.3.2 Regeneration of the water treatment units
For the regeneration of the water treatment units, please consult
the relative user’s manual and follow the instructions therein.
