Do not close the steam release knob before
all steam is released or machine has been
turned “off“!
(see section CAUTION - PRESSURE).
ATTENTION:
The top closure of the “Perfect Froth“
attachment (see figure 18, part A). has a
very fine hole which draws air into the milk.
If this tiny hole gets clogged, “Perfect Froth“
will not work properly. Therefore, never
immerse the top closure in milk or froth.
Before cleaning, turn “off” the machine,
unplug it, and allow it to cool down.
The filter holder, filter basket, carafe, carafe
lid, and overflow grid can be put in the
dishwasher’s upper rack, away from the
heating/drying element.
The machine can be wiped clean by using a
damp cloth. Never immerse the body of
your “Il Caffè Duomo” in water or any other
liquid. Clean the brewing head with a damp
cloth and remove ground coffee. If there is
water left in the boiler chamber, let the
machine cool down, remove all loose parts
and empty through the top opening by
turning upside down.
Cleaning the Steam Nozzle
Clean the steam nozzle each time after you
have immersed it in the milk, otherwise the
inside of the nozzle becomes clogged and
the milk deposits on the outside harden and
become difficult to remove.
■ If clogging does occur, unscrew the tip of
the steam nozzle (see figure 16).
Remove all milk particles using a sewing
needle and rinse under the faucet. Replace
nozzle tip making sure to screw it on tightly.
Wipe off the outside of the nozzle with a wet
cloth. Hold the wet cloth very close to the tip
of the nozzle and open the steam valve.
Let the steam escape into the wet cloth for
one or two seconds, then close the valve.
Any milk residue will then be flushed out.
Cleaning the “Perfect Froth“ Attachment
■ For a thorough cleaning of the “Perfect
Froth” attachment, remove part C
(see figure 18).
All parts should be rinsed in warm water.
If the small suction opening in part A is
clogged up, it can be opened with a fine
needle.
Cleaning the Drip Tray
■ The overflow grid can be cleaned by
removing the grid (see figure 19).
CAUTION
Do not try to open or disassemble the main
body of the machine.
The espresso machine must be decalcified
regularly. The frequency depends on the
hardness of your water and how often you
use the espresso machine.
Before descaling, the brewing sieve on the
brewing head
must first be screwed off.
1. Remove all lime and coffee residues from
the brewing sieve and the brewing head.
2. Pull off the “Perfect Froth“ attachment.
For ecological and health reasons, we
recommend the exclusive use of biological
materials such as citric acid, which can be
obtained from KRUPS Consumer Service
Department or drugstores.
3. Dissolve 2 tablespoonfuls of citric acid in
10 fluid ounces of lukewarm water and
pour it into the boiler container. Put one
receptacle under the brewing head and
another under the steam nozzle.
(
Note: Do not use the filter holder during
decalcification)
4. Open the steam valve and turn on the
appliance. Allow the descaling solution to
run out of the espresso outlet and the
steam nozzle.
5. After each brewing cycle, switch off the
appliance and allow the appliance to cool
down.
