7.9 Descaling
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.
The time interval between descaling depends on the hardness of the water
and frequency of use. Failure to descale the appliance will likely impair its
functions or cause damage to the appliance.
The descaling programme takes about 1 hour and 20 minutes. «durgol swiss
steamer» descaler is mixed in the ratio of 1:2 (e.g. 0.5 l durgol to 1 l water). If
the «Refresh» or «Hygiene programme» is used every second day, the follow-
ing descaling intervals can be expected:
Water hardness (see page 38) type Descaling interval
▪ Hard About every 3 months
▪ Medium About every 4 months
▪ Soft About every 7 months
Descaler
Durgol swiss steamer
Using the wrong descaler can damage the appliance!
Only use «durgol swiss steamer» to descale your appliance.
The descaler contains highly effective acid. If dripped or smeared (and
left to dry) on smooth metal or plastic surfaces or polyamide textiles
can cause stains. Immediately rinse away any splashes with water.
Follow the manufacturer's instructions.
See «Accessories and spare parts» (see page 49) for where to ob-
tain this descaler.
Standard descaling solutions are not suitable as they may con-
tain 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.
