8.7 Cleaning the accessories and shelf guides
▪ The stainless steel tray, perforated cooking tray, water tank and shelf guides can be
cleaned in the dishwasher.

not use washing-up liquid or any abrasive agents).
▸ If the water tank valve drips, descale it.
Removing the shelf guides
▸ Unscrew the knurled nuts 1 in the
front of the shelf guides in an anti-

position on the screws. Place the knurled nuts on the screws and tighten securely in a
clockwise direction.
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».
