Descaling
If the water in your local area is hard, lime scale will form over
time.These deposits may affect the correct operation of the appli-
ance.
The appliance should be descaled every 40 cycles.To descale,
always use a special descaling product for filter coffee machines
available on the market. Alternatively, citric acid can be used.
Proceed as follows:
• fill the carafe with four cups of water: empty into the water
tank.
• dissolve two spoonfuls (about 30 grams) of citric acid (available
in chemists or drug stores) and pour the solution into the
water tank;
• place the carafe on the hot plate and the filter holder into place
without ground coffee;
• press the ON/OFF coffee button (electronic models) or the O/I
button (mechanical models), filter the equivalent of two cups
then turn the appliance off;
• leave the solution to act for an hour;
• turn the appliance on again and allow the rest of the solution to
filter through;
• rinse by operating the appliance with water only at least three
times (a full carafe at a time).
