depending on water hardness – roughly as follows:
Water hardness
Very hard
Hard
Medium
Soft

The approximate operating time remaining with steam until the next descaling can be
called up in the user settings under «Descaling».

Using the wrong descaler can damage the appliance!
Only use «durgol swiss steamer» to descale your appliance. The descaler contains
highly effective acid. Immediately rinse away any splashes with water. Follow the
manufacturer's instructions.
See «Accessories and spare parts» for where to obtain this descaler.
«durgol swiss steamer» was developed especially for this appliance.
Standard descaling solutions are not suitable as they may contain foam-
creating additives or not be effective enough.
Using a different descaler could cause
▪ overfoaming inside the appliance
▪ insufficient descaling of the boiler
▪ damage to the appliance in the worst case.
Starting descaling
The appliance must have cooled down before descaling.
Remove accessories, cookware or other objects from the cooking space. Do not
leave the appliance unattended: during the descaling process, the descaler must
be added and the water tank must be emptied. The appliance door must be
closed during descaling.
