. The percolation head, the filter holder
and the filters
These must be cleaned after every use. Simply
run a damp cloth over the percolation head
and clean the other accessories with water
and a small quantity of non-abrasive liquid
cleanser. Rinse and dry.
• If the percolation head becomes heavily
encrusted, unscrew its grid using a coin,
clean it and replace, tightening it firmly (9).
. The seal for the percolation head
When you are not using your espresso, do not
leave the filter holder in the appliance in order
to prevent wear on the seal.
• Clean the seal regularly using a damp cloth.
. The steam nozzle (g)
• It must be cleaned with a damp cloth after
every use.
Please note: it may still be very hot!
For more thorough cleaning, the nozzle may
be taken off (10):
• Unscrew the tip (g1), if necessary using a
coin.
• Separate the various components and clean
them with hot water and a small quantity of
non-abrasive liquid cleanser. Rinse and dry.
• If need be, unblock the tip (g1) using a fine
needle.
Descaling
It is vital that you descale your espresso
machine in order to guarantee its continued
operation.
• Descale your espresso at regular intervals
using citric or tartaric acid.
We do, however, advise you to use the Krups
descaling accessory, reference 054, which
is available from approved Krups service
centers. This accessory includes, in addition to
two doses of descaler, a water hardness test
strip to evaluate the frequency of descaling
for your appliance in normal use. The amount
of scaling depends on the hardness of the
water, but also on how often it is used. The
frequency of descaling indicated by accessory
054 is thus given by way of indication only.
You must never, under any circumstances, use
classic sulfuric acid or other products
containing this acid as there is a risk of
damaging the appliance. Carefully check the
composition of the descaling products you
intend to use.
- Then use the following method:
• Unscrew the grid of the percolation head
and clean it (9).
• Dissolve 2 tablespoons of descaler or one
packet of accessory 054 in half a liter (16 oz)
of lukewarm water and pour the mixture
into the empty water tank.
• Set the «on/off» switch (h). The indicator
light (h1) comes on.
Once the appliance reaches the appropriate
temperature, the temperature control
indicator light (c) comes on.
• Place a container under the percolation
head. Run through about 1/3 of the mixture,
setting the function selector (b) to the
position «
».
• Set the «on/off» switch (h). The indicator
light (h1) comes off and wait 10 to 15
minutes to allow the descaler to take effect.
• Then set the «on/off» switch (h). The
indicator light (h1) comes on.
• With the function selector (b) in the position
« », allow the remainder of the mixture to
run into the container placed under the
percolation head.
• Then reset the function selector (b) to O.
• Run two tanks of fresh water through to
rinse the percolation head. To do this:
. fill the tank
. place a container under the percolation
head, set the function selector (b) to « »
and allow the content of the tank to run
through.
. then set the function selector (b) to O.
• Set the «on/off» switch (h). The indicator
light (h1) comes off
. replace the grid on the head of the appliance
(see paragraph «Maintenance») (9).
Notes:
In the case of serious scaling, soak the grid of
the percolation head for 5 minutes in 1/3 of
the mixture obtained during the first run-
through.
If necessary, this operation can also be
performed with the steam nozzle:
