Descaling
Whenever steam is produced, irrespective of the hardness
of the local water supply (i.e. the limescale content of
the water), limescale is deposited inside the steam
generator.
The time interval between descaling depends on the
hardness of the water and frequency of use. If steaming
4×30 minutes per week, the appliance must be descaled
(depending on water hardness) roughly as follows:
Water hardness
Very soft
Medium
Very hard
The appliance automatically detects when descaling is
necessary and when this happens the Descale light stays
on.
If the Descaling procedure is not performed, some
cooking cycles after the Descale light starts to flash.
If once again the Descaling procedure is not performed,
some cooking cycles after the oven functioning is
blocked, the Descale light stays on and the display
shows "CAL" blinking.
IMPORTANT NOTE: Failure to descale the appliance will likely impair
the functioning of or cause damage to the appliance.
Suitable descaling solutions
For descaling, use the descaling solution "durgol" or
other professional descaling solution which allows a careful
descaling of your appliance. Please contact the Customer Care Centres.
Warning! Do not use vinegar or vinegar-based products as they can
cause damage to the oven's internal circuit.
Traditional descaling solutions are not appropriate because they can contain
foaming agents.
