Cleaning (Daily)
Cleaning the Diffuser Screen. During the discharge
operation (subsequent to coffee brewing), small amounts
of coffee grounds may slowly build-up on and obstruct,
even partially, the diffuser screen. Remove the diffuser
screen by unscrewing the diffuser screw. Place 2 or 3
teaspoons of detergent powder for coffee machines in
about 1/2 a litre of hot water. Place the diffuser screen
and diffuser screw in the solution and leave them fully
submerged for about 30 minutes. Rinse thoroughly with
clean water. Install and run hot water through the group
head several times with the screen installed.
Cleaning the Brewing System. Remove the
diffuser screen as described in the previous
step. Install the blind fi lter into one of the supplied
portafi lter handles. Place a tablespoon of detergent
powder for coffee machines into the blind fi lter and
install the portafi lter into the espresso machine.
Cycle the espresso machine on and off using the continuous
button. Cycle approximately 10-20 times. The cycling
of the espresso machine allows the detergent powder to
fl ow through the brew system cleaning the components.
Remove the portafi lter from the espresso machine.
After cleaning, rinse the group head by activating the
continuous button or approximately 10 seconds. Using
a damp cloth wipe clean the area where the portafi lter
engages into the group head. Then replace the diffuser
screen.

Cleaning fi lter baskets and portafi lter handles
- Put 2 or 3 teaspoons of detergent powder for coffee
machines in about 1/2 liter of hot water.
- Dip fi lters baskets and fi lter holders into the solution,
being careful not to allow any rubber or plastic parts
to contact the solution, and leave submerged for
about 30 minutes.
- Rinse thoroughly with clean water and run hot water
through the group several times with the fi lters in
place.
- Make one cup of coffee and discard in order to
remove any unpleasant fl avor remaining from the
cleaning process.
Cleaning the Drain Box. Remove the drain box
assembly and wash each of the components with hot
soapy water. Rinse thoroughly and reinstall the drain
box assembly. All components of the drain box assembly
are dishwasher safe.
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, imprinted, or plastic parts in
order not to damage them. Clean the side panels using
a soft cloth. Do not spray the keypad or display with
any liquid. Clean only with a damp soft cloth.
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 fl avor of other
drinks to be heated. Hot water nozzles must be cleaned
periodically with a damp cloth. If milk residue is present
on the steam wand, soak the tip in a container of hot
water. After you can wipe the tip clean. Repeat process
if residue remains.
NOTE: This cleaning schedule is based upon a moderate
to average use (20-300) cups per day. If machine use is
less than moderate then this schedule may be adjusted
accordingly.
