2. The filter holder
„ Using a damp cloth, regularly clean the filter holder housing in order to remove any
residual coffee that may have collected in this area.
„ Do not remove the seal. Do not remove the screws from the filter and filter holder.
This may only be carried out by an approved servicing centre.
„ To prolong the life of the filtering head seal, do not refit the filter holder if the coffee
machine will not be used for an extended period of time.
3. The drip tray
„ If necessary, clean the drip tray (I) and its grill (H) using water and a little mild detergent
(44-45). Rinse and dry.
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
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.

acid (total volume of mixture: 500 ml)
„ Plug the appliance in. Turn on the appliance by pressing the On button.

switches on, turn the thumb wheel to the left and allow the mixture to flow through (¼ of
the volume).
