1 SAFETY ADVICE

Before commencing repairs, ALWAYS disconnect the
appliance from the power supply! If tests have to be
performed while the appliance is live, ALWAYS use a
residual-current-operated circuit-breaker! When repairs are
completed, perform a function and leak test as well as a
test in accordance with VDE 0701.

3 OPERATION

3.1 Manual operation

Choose operation mode (humidity) and temperature. The
display shows operation symbols and the required end
temperature. When changing the operation mode you will
see (instead of the required end temperature) the humidity
in % for about 2 sec. By pressing button < 9 > you will see
the actual temperature (thermo-test).

When you open the door during operation the heating
element and the hot air fan are switched off and the water
injection stops.

Condensation

The function „condensation“ is limited to temperatures from
30°C/85°F bis 125°C/260°F and works only in connection
with the humidity levels 100 %; 80 % and 60 %.

Press button <

> for ca. 1 sec. The cooking process is
interrupted. for ca. 20 sec. The steam is condensed in the
inner oven. After this period, you will hear an acoustic
signal and the cooking process is continued, if the door ist
not opened.

The condensation process can be interrupted by opening
the door or by once more pressing button <

>.

Vaporization

The function „Vaporization“ works only in connection with
the humidity level 30 % and 0 %. (hot air function)

Press button <
as button <

>. The vaporization process lasts as long

> is pressed, but max. 8 sec. By pressing it

once more, the process is repeated.

3.3 Cleaning support

Turn both operation knobs from the upright position one
step to the left side. The disply shows the flame symbol
(no pyrolysis) as well as the period 00:30 min. (Appliance
heats up on 60°C/140°F with 100 % humidity).

Press button < 9 > in order to start the process.

3.12.3 How to fade out the time
Keep button < 9 > pressed and turn the humidity switch

one notch to the right.

Keep button < 9 > pressed and turn the humidity switch
one notch to the right.

Let button < 9 > go.

Let button < 9 > go.
Now turn the humidity switch two notches further. The

display shows “h/min.“ and the time.
With button < + > you can fade out the time. Confirm with
< 9 >.
Turn the humidity switch on < 100 % >.

3.12.4 Calibration / Height comparison

The boiling point of water depends on the air pressure.
To guarantee the optimal function of the steam oven, it
has to be adjusted in the place to the air pressure
conditions (varies with the height above sealevel)
before you run it for the first time. This so called
calibration process must not be interrupted, e.g. by
opening the door, otherwise the steamer cannot work.

The calibration process is started automatically at the
first operation of the appliance. When moving lateron to
a place with another hight above sealevel, the
calibration process has to be effected again over the
option menu.

Now turn the humidity switch three notches further. The
display shows < CAL > . Now turn the temperature switch
on min. < 30°C/85°F >.

After ca. 3 sec. The display shows over CAL a <

>

symbol and the time turns to the period of
< 00:18 min. >.
The calibration process is started now and the period of

00:18 min. expires.
After the calibration process you will hear an acoustic signal

and the display shows four dashes < - - - - > .
Turn the temperature switch on position < 0 >. The

appliance is now ready for function.

Hint

When the calibration process is stopped earlier and when
you try to start it again, the display shows alternatingly
< CAL > and < 40°C/105°F >, if the inner oven temperature
is higher than 40°C/105°F.

Open the oven door and let the appliance cool down for a
while. When the temperature is below < 40°C/105°F >, the
calibration process can be started again.

3.12.5 Exhibition mode

To deactivate

Ex works the appliance is programmed with the
exhibition mode. The display shows staticly <

>. In
order to deactivate the exhibition mode, the appliance
has to be calibrated. See „To deaktivate“.

To activate:

Close the water supply.
Keep button < 9 > pressed and turn the humidity switch

one notch to the right.
Let button < 9 > go.
Now turn the humidity switch three notches further. The

display shows < CAL >.
Now turn the temperature switch on min < 30°C/85°F > and

press button
< 9 > three times within 5 sec. The calibration is

interrupted..
The display shows four dashes < - - - - > and you will hear

an acoustic signal.
Turn the temperature switch on position < 0 >. The display

shows staticly <

>.

Open the water supply.
Turn the temperature switch on min. < 30°C/85°F >.
The appliance starts now a calibration process as at its

initial operation; see point 12.4.

3.12.6 Indication of the hardness of water / Indication and
reset of decalcifying

Hint

The appliance has no integrated decalcifying installation.
The time how fast the decalcifying symbol

> is shown in the display, differs depending on the set

<

water hardness 1, 2, 3 or 4 (see b) indication of
decalcifying)

Important

When the investigated water hardness is above 7°dH, then
the appliance needs a decalcifying installation: Typ Brita
Aqua Quell 33/Nr. 2780. This installation approved by us
can be ordered in a specialist shop or under the following
adress: Fa. Brita Wasserfilter Systeme GmbH

Heinrich-Hertz-Straße 4

D – 65232 Taunusstein

All values which were investigated before in a
successful calibration process are now deleted from
the EEPROM.

Set the range with button < + > or < - > according to the
value investigated before and confirm with button

< 9 >.
Turn the humidity switch on < 100 % >.

b) Indication of decalcifying
Is the symbol <

> blinking in the display, the water

supply hose in the inner oven has to be removed (behind
the air deflector panel on the left side) and decalcified. The

flange for the water supply hose can be cleaned now with
help of the auxiliary tool/BSH-No. 180751

delivered

together with the appliance.

Keep button < 9 > pressed and turn the humidity switch
one notch to the right.

Let button < 9 > go.
Now turn the humidity switch four notches further. For the

hardness of water, the display shows a range from 1 to 4
(ex works set on 4) and it shows the symbol <

>

Press button < 9 > in order to set the meter of the operation
hours on zero.

Turn the humidity switch on < 100 % >.

Insert the tool into the drilling and turn it to the right and to
the left. The display shows after the below mentioned hours
of operation the blinking symbol <

> depending on the

setted value of water hardness:
4= 070 h / 3 =100 h / 2= 200 h / 1 = 400 h
