3.5 Operation of STAR burners
Press in on the knob and turn it counter-clockwise to the HI setting, the igniter for the
selected burner sparks to ignite the burner. When flame is present the igniter stops
sparking. Rotate the knob to any flame setting between HI and SIM. A blue light is posi-
tioned directly above each knob. When the knob is rotated to any active position the
light illuminates.

3.6 Extra Low STAR Burners
Caution
Hot components!
Burns
▶Allow components to cool before touching.
The ExtraLow burners can be set lower than the SIM setting on a normal burner. The
control knob has an extra range between the SIM and XLO settings. The heat is re-
duced for low temperature cooking, such as melting chocolate and butter, by varying
the length of time the flame is on.
The XHI is located at the right-front position of the rangetop. It offers the convenience
to quickly boil water, sear steaks, stir-fry vegetables, etc.
Checking Cap Placement
Check each burner to make sure there is no gap between the burner cap and burner
base. You may gently try to move the burner caps from side to side to check if the caps
are properly placed on the burner bases. When properly placed, each burner cap will
rest flat on top of its burner base and completely cover the star-shape of the burner
base when viewed from the top as shown.
Examples of correct and incorrect placements of the burner cap are shown below.
1 Correct cap placement
2 Incorrect cap placement
Cap placement
The burner caps must be properly placed on the burner bases for the rangetop to func-
tion properly. If the burner cap is not properly placed, one or more of the following prob-
lems may occur
Design and function
2019-04-13_58300000217218_ara_en_a Copyright by BSH Hausgeräte GmbH Page12of85

¡Burner flames are too high
¡Flames shoot out of burners.
¡Burners do not ignite.
¡Burner flames light unevenly.
¡Burner emits gas odor.
1. Burner cap
2. Igniter
3. Burner base
Each Star burner has its own electronic igniter that sparks when the burner is turned
on. Each burner should light in 4 seconds or less. If a burner does not light, check to
see that the burner cap is positioned correctly on the base.

3.9 Soft-close device in oven carriage
When the oven carriage is closed, the pin (5) pushes the soft-close device (4) out of its
rest position. In doing so, the soft-close device (4) firmly encloses the pin (5). The soft-
close device (4) is released and pulls the oven carriage shut.
Shortly after the pin (5) is firmly enclosed by the soft-close device (4), the damper (1)
hits the damper stop (4) and is tensioned as a result. This brakes the insertion move-
ment.
When the oven carriage is opened, the pin (5) pulls the soft-close device (4) into the
rest position. The soft-close device (4) is fully tensioned in its rest position. When the
soft-close device (4) has reached its rest position, the pin (5) is released again. When
the oven carriage is opened, the damper (1) is removed from the damper stop (2) and
is released as a result.
