1) Cleaning groups and drain wells
- Put a tablespoon of detergent powder
for coffee machines into the blind filter,
supplied with the machine, and tighten
it onto the group you want to clean by
using a normal filter holder.
- For AV models: activate the automating
rinsing (backflushing) routine (see the
Software Programming Manual for more
detailed instructions). For MP models:
brew water for 3 sec and repeat ten
times for each group.
- Rinse the group using a normal filter,
by running hot water through it several
times
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
