Use caution when descaling your espresso
•
machine as the acid substance within the
descaling powder may damage countertops
or any other surface it comes in contact
with.
• The warranty of this machine does not
include espresso machines that do not
function, or do not function properly,
because descaling has not been carried
out.
We would advise you to use the Krups
descaling solution that is available from Krups.
Descaling depends on the hardness of the
water, but also on the frequency of use.
- To descale follow the following method:
• Unscrew the grid from the head of the
machine and clean it (21).
• Dissolve a packet of KRUPS descaling
solution in 17 oz/510 ml of lukewarm water
and pour the whole batch into the empty
water container.
• Start the machine (4).
• Place a container, as large as possible,
beneath the auto cappuccino accessory.
As soon as the start/stop switch begins to
glow continuously, the machine is ready.
• Press the hot water button
through 1/3 of the liquid.
• Press the hot water button again
stop.
• Move the container under the brewing
head.
• Run the second third of the liquid
immediately by pressing the coffee button
(10) as many times as necessary.
• Stop the machine by pressing the start/stop
switch (4) and wait for 10 - 15 minutes to
allow the descaler to take effect.
• Next, start the machine again (4) and allow
the rest of the liquid to run through by
pressing the coffee button
many times as necessary.
• Then rinse with two water containers of
fresh water, clean the brewing head and
replace the grid on the head of the machine
(see section on Cleaning the Machine).
