12.8 Descaling
How it functions
Whenever steam is produced, depending on the hardness of the local water
supply (i.e. the limescale content of the water), limescale is deposited in the
boiler.
The appliance automatically detects when descaling is necessary and indic-
ates this information.
– After pressing the touch button and at
the end of each cooking process, the following
appears in the display:
Would you like to descale the
appliance now?
You must accompany the pro-
cess.
We recommend descaling the appliance whenever the warning ap-
pears in the display.
Continued failure to descale the appliance will likely impair its func-
tions or cause damage to the appliance.
Descaling takes about 45 minutes.
Descaling interval
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
Hard 5 months
Medium 8 months
Soft 12 months
Read remaining operating time
The remaining steam operating time until the next descaling process can be
read in the user settings under «Descaling».
