For internal use only
• The process of descaling is only completed when the water tank is removed after two rinsing
phases have been fully implemented.
In the event of a power cut during the descaling process, the descaling program will be repeated or will
continue with operation from the procedure step (Descale, 1. or 2. Rinse) in which the power was cut off.
In addition, all of the indications, apart from the time, will be deleted. The time blinks at 12:00.
Attention! Modification from 2003 on
There are three new setting ranges for the water hardness (soft, medium, hard) among the user
adjustment. The medium water hardness is pre-adjusted, covering the usual range from 9 to 20°C
German hardness (resp. 16 to 35° C French hardness).
The descaling interval depends from the respective water hardness. For this reason it will be
automatically displayed in the clear text display, if descaling is necessary.

Programme time: 40 minutes
Each time steam is generated lime will be deposited in the steam generator depending on the degree of
hardness of local water (i.e. on the concentration of lime in the water).
A system in the appliance will recognise automatically when it is essential to descale.
The display will blink .
The descale cycle will depend on the respective water hardness and on how frequently the appliance is
used. For steaming for 30 minutes four times a week descaling will approximately be required as follows,
depending on the water hardness (with three settings for water hardness):
We recommend that you descale as soon as the display indicates that it is essential. If the appli-
ance is not descaled the functioning may be impaired or the appliance may be damaged.
Experience has shown that standard commercially-available descaling agents are not always effective.
These agents generally contain foaming tensides, cause corrosion or do not fully dissolve the lime-
scaling, which may result in faulty operation or damage to appliances.
Frothing means that the descaling process is not carried out properly which results incorrect readings in
the appliance.
Conducting bridges of foam may result from the level sensor so that the appliance never recognises that
the descaling or rinsing process has been completed and will hence never re-set the descaling metre.
