Descale your appliance regularly, as indicated in sections A and B for the coffee and steam
functions, as this will help prolong its lifespan. The frequency of descaling depends on the
hardness of your water. Consult your water supply authority for more information.
While descaling, do not place your appliance on a marble worktop. The descaling agent
could damage it.
• To help you, here is a table of reference for the frequency of descaling according to water
hardness and how often your machine is used:
Average no. of coffees per
week
Less than 7
7 - 20
More than 20
If in doubt, descaling once per month is advised.
The coffee maker will not be repaired if:
• descaling is not carried out,
• there are scale deposits,
• the accessories have been washed in a dishwasher,
as this is not covered under the guarantee.
A. Descaling the coffee system
• Unplug the appliance.
• Insert the filter holder (without coffee) into the appliance and turn it to the right until it
stops.
• Place a receptacle with a volume greater than ½ litre under the filter holder.
• Check that the thumb wheel is set to position O.
• Fill the tank with a mixture comprised of 3 parts water to 1 part vinegar or citric/sulphamic
acid (total volume of mixture: 500 ml)
• Plug the appliance in. Turn on the appliance by pressing the On button.
• Set the selection button to the espresso position. When the espresso indicator light
switches on, turn the thumb wheel to the left and allow the mixture to flow through (¼ of
the volume).
• Stop the appliance by pressing the On/Off button and leaving the selection button set to
Espresso.
• Wait 5 to 10 minutes, then repeat the process twice more.
• Make sure that the tank does not fully empty (if removing, refer to the paragraph: FIRST USE).
B. Rinsing
IMPORTANT!
After descaling, rinse 2-3 times using clean water (no coffee), as described
in the "FIRST USE" paragraph.
Do not forget to rinse the nozzle. The appliance is now descaled and ready for use again.
