Descaling the filter coffee section
Formation of scale depends on the hardness of the water and on
how often the coffee machine is used.To obtain optimum perform-
ance, the appliance should be descaled regularly, at least every 40
cycles.
To descale, proceed as follows:
1. Fill the carafe with four cups of water;
2. Dissolve two spoonfuls (about 30 grams) of citric acid (available
from chemists or drug stores) in the carafe and pour the solu-
tion into the water tank.
3. Place the carafe on the hot plate and the filter holder without
ground coffee.
4. Filter the equivalent of two cups then turn the appliance off.
5. Leave the solution to work for 15 minutes, then repeat steps 4
and 5 once again.
6 Turn the appliance on again and allow the rest of the solution
to filter.
7 Rinse by operating the appliance with water only at least three
times (a full carafe each time).
Repairs for malfunctioning caused by problems of calcium
build-up are not covered by the guarantee if the descaling
process described above is not carried out regularly.
