Descaling Program; Water Filter - Melitta Latticia OT Bedienungsanleitung

7.6 Descaling program

The descaling program is used to remove
limescale deposits. You should run the
program every three months or when the
appliance asks you to do so.
There must not be a water filter in the
water tank during descaling. If you use a
water filter, you need to remove it before
descaling (see section 7.7, page 29).
Only use Melitta® Anti Calc liquid descaling
agent for automatic coffeemakers.
Caution! Descaling agent causes eye
irritation. If it accidentally comes into
contact with your eyes, you should
rinse them with clear water for several
minutes. Consult a doctor if symptoms
persist.
The program takes approximately 15 min-
utes and should not be interrupted. The
program runs in several stages. Progress is
indicated by the number of coffee beans
displayed.
The Descaling display light tells
you to descale the appliance.

If the descaling program has been inter-
rupted, e.g. by unintentionally switch-
ing the appliance off, you must switch
the appliance on again and follow the
instructions from step 8. The appliance is
then ready for operation, even if it has not
been completely descaled. For complete
descaling, you need to start the descaling
program again.

7.7 Water filter

The use of a water filter extends the service
life of your appliance. The water filter filters
calcium and pollutants out of the tap
water.
If you use a water filter and change it on a
regular basis, you will need to descale the
appliance only once per year. This informa-
tion is based on an average of six 120 ml
coffee beverages per day and six filter
changes per year.
Only use Melitta® Pro Aqua filter cartridges
for automatic coffeemakers. Observe the
instructions on the packaging of the filter
cartridge.
