Checking the cooking sensor (Lambda sensor)
It is
not
possible to improve the function of the cooking sensor by
manually calibrating it in the Service program!
Only new cooking sensors may / must be calibrated, once only,
in the Service program (coordinates the cooking sensor with the
sensor module)!
Fig. 43:
Position of the cooking sensor (in the roof of the cooking compartment
at back right)
1. Check whether the openings in the metal housing of the cooking sensor are
soiled or blocked.
2.
Water or moisture will damage the cooking sensor!
► Do not clean the cooking sensor with wet or moist utensils.
Clean soiled or blocked openings in the metal housing of the cooking sensor
with a
dry
brush.
3. Start the Lambda sensor test in the Service program
4. Read off the
Ipump
µA value.
5. Read off the
Probe service
% value.
Result:
The values
Ipump
4000 µA ± 1000 µA and
Probe service
between 100 % and
90 % are normal.
With values of
Ipump
3000 µA ± 1000 µA and
Probe service
between 89 %
and 60 % the appliance can still function. Dishes that incorporate only a little
moisture may encounter problems with values Ipump between 3000 µA and
2000 µA.
The appliance
cannot
operate with values
Ipump
< 2000 µA or
Probe service
< 60 %.
6. Replace the defective cooking sensor.
7.
Calibrate the new cooking sensor manually in the Service program.
