9. DESCALING
The guarantee does not cover appliances which become faulty because the descaling operations have not
been carried out regularly.
Descale your espresso maker regularly using commercial white vinegar (available from hardware stores)
or a packet of citric or sulphamic acid which you can buy in most hardware stores.
We recommend that you use the Krups descaling accessory, reference F054, available in Krups
authorized service centres. In addition to two descaling sachets, this accessory includes a water hardness
tape tester to assess the required frequency with which your appliance should be descaled, in normal use.
The amount of scale depends on the hardness of the water but also the level of use. The frequency of
descaling given by the F054 accessory is therefore purely indicative. However, you can refer to the
following table:
Ave. number
coffees per week
Less than 7
From 7 to 20
Over 20
DESCALING OF THE STEAM AND COFFEE CIRCUIT
n Empty the tank and put it back in place.
n If your appliance is fitted with our Claris - Aqua Filter System F088 cartridge, please remove the
cartridge before the descaling operation. You should also remove the steam nozzle or auto-cappuccino
accessory.
n Fill the tank with a mixture composed of three parts water for one part commercial white vinegar or a
mixture of ½ litre of water and a packet of descaler available in the shops.
n Insert the filter holder (without espresso ground coffee) into the appliance and lock it by turning it to
the right as far as it will go.
n Place a container under the steam nozzle.
n Press the "on-off" button (fig.4). During the pre-heating phase, the indicator light will flash.
n Once it stops blinking, turn the knob to the "steam" position (fig.13) and let 100ml of this mixture drain
flow through (the equivalent of a mug) and then turn the knob back to the "0" position (fig.15).
n Place a container of sufficient volume under the filter holder.
n Once the light stops flashing, press the "2 cups" button and let the water flow through before repeating.
n Turn the appliance off by pressing the "On / Off" button immediately after this second cycle.
n After 15 minutes, turn the machine back on.
n Make the rest of the water run through into a recipient by pressing the "2 cups" button.
RINSING
IMPORTANT!
After descaling, perform 2-3 rinsing operations with clear water (without espresso
ground coffee), as described in paragraph 5 "using for the first time".
Remember to rinse the steam circuit by following the instructions below:
n Place a container under the steam nozzle.
n Press the "on-off" button.
n Once the "on/off" light stops blinking, turn the knob to the "steam" position (fig.13) and let the water
drain through the nozzle until the steam begins to appear and then return it to the "0" position (fig.15).
The appliance is descaled and ready to be used again.
