9. DESCALING
• Regular descaling of your appliance, as
mentioned in paragraphs A and B for the
coffee and steam functions, is the best
guarantee of your machine's long life. The
frequency of the descaling operations must
be adapted to suit the hardness of your water.
Ask for advice from your local water
authority.
• During the operation, do not stand your
appliance on a marble surface. The descaler
could affect it.
• To make this clearer, please find below a
summary table of the frequencies of the
descaling operations according to the
hardness of water and use:
If in doubt, we recommend carrying out a
descaling operation every month.
No repairs to your machine will be carried out
due to:
• descaling not being carried out,
• scale.
A. Descaling of the coffee function
• Unplug the appliance.
• Insert the filter holder (without ground coffee)
into the appliance and lock it into place by
turning it towards the right as far as possible
(fig. 3) .
• Place a recipient with a volume of more than
1/2 litre under the filter holder (fig. 4) .
• Check that the selector d1 is in the position
"0".
• Empty the tank and put it in place.
• Fill the tank with a mixture of three parts
water to one part vinegar or citric acid.
• Switch on the appliance.
• Place the D3 button in the maximum volume
position.
• When the temperature light of the ON/OFF
button remains lit, you can then switch to the
position
(coffee) (fig. 5) .
• Press the D4 1 cup button.
• Let the mixture flow through.
• Wait for 2 minutes then repeat the operation
twice, from the step of pressing the D4 1 cup
button.
• Turn the selector to the position "0".
• Now follow the instructions for descaling the
steam function.
B. Descaling the steam function
• Next place the recipient under the steam
nozzle.
• Turn the selector d1 to the position (steam
heat) (fig. 13) (to obtain steam, the
temperature must be higher than that
required for coffee).
• the LED of the ON/OFF button flashes then
remains lit.
• Turn the selector d1 to the position (steam
extraction) (fig. 14) : the steam pours into
the liquid. Let the rest of the mixture flow for
2 minutes.
• During the operation, it is normal for the
water temperature light to light up and then
go out.
• After a few moments, stop the appliance
(position "0").
• When the selector d1 is in the position "0", the
appliance cools down automatically. During
the cooling down phase, the LED of the
ON/OFF button flashes and hot water runs
into the drip tray.
