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 and indicates when descaling is necessary.
– After pressing the
touch button and finishing a cooking process, the following ap-
pears in the display:
Would you like to descale the appliance now?
You must accompany the process.
We recommend descaling the appliance whenever the warning appears in the dis-
play. Continued to descale the appliance will likely impair its functions 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 fre-
quency 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».
