8.8 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 and indicates when descaling is necessary.
The cleaning programme guides you step-by-step through the descaling process.
We recommend descaling the appliance whenever the message appears. Contin-
ued failure 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
Very hard 5 months
Hard 7 months
Medium 9 months
Soft 12 months
Calling up the remaining operating time
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.
