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 Descale after about
Very soft 18 months
Medium 9 months
Very hard 6 months
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 steam cooking cycles may
not function 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
®”.
This solution allows a professional and careful
descaling of your appliance. Available at 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.
