Basic settings
Water Hardness setting
The appliance features a system that
automatically indicates when it is time to descale.
The system can be optimised for households with
very soft water (also through using a water
softening appliance) and very hard water, by
changing the user settings to the relevant range of
water hardness (see table below).
To set the water hardness parameter, proceed as
follows:
1. Rotate the Rotating knob (1) to the descaling
symbol. “” will start to flash (by default) on
the display (not necessary if your oven is first
plugged in or after a power failure).
2. Turn the rotating knob (2) to set the correct
water hardness parameter value, according to
the below table.
3. Press the OK key (5) to set the parameter. The
display shows the clock.
