5.6 Recognising a steam leak with the climatic sensor
Leaks, such as those caused by damaged or dirty door sealing, insufficient sealing of the hot air motor
shaft, open vent flaps, blocked steam emissions, climatic sensors which are full of water or anything
similar, will distort the temperature reading of the climatic sensor. A possible distortion of this nature is
determined by monitoring the measurement of the temperature on the climatic sensor. Should, over a
certain period, the steam temperature fall below the threshold value for the climatic sensor, the
difference between the maximum and minimum temperature of the climatic sensor is determined.
Should this reading fall below a certain reading, the F9 fault indication: “contact service” (steam leakage
monitor actuated) will be shown on the clear text display.
5.7 Fan, follow-on time and steam dissipation
By means of air circulation, the temperature-regulated follow-on time of the ventilator fan serves the
purpose of achieving a certain drying effect in the oven and on the ventilating system.
This involves the ventilator fan and the hot air fan being operated with opened inlet air flaps and vent
flaps at a certain setting until the oven temperature has fallen below a certain level.
During the operating modes steaming, regenerating and, if so required, hot air with steam vapours, an
additional active process of steam dissipation takes place.
