13.6 Pyrolysis: automatic oven cleaning
Pyrolysis is an automatic high-temperature cleaning procedure which causes dirt to dissolve.
Before starting the automatic cleaning cycle, make sure that the oven does not contain any foods or
large spills from previous cooking operations inside.
A door interlock device means that the door cannot be opened during the procedure.
IF THE OVEN IS INSTALLED UNDERNEATH A HOB, MAKE SURE THAT THE BURNERS OR
ELECTRIC PLATES REMAIN OFF DURING THE AUTOMATIC CLEANING CYCLE.
13.6.1 Before starting the automatic cleaning cycle
Pyrolysis may be carried out at any time of the day or night (if you wish to benefit from the lower cost of
electricity overnight).
Before proceeding, check the following:
• only the baking tray, the oven tray and the roof liner may be left inside the oven since they will
withstand the high temperatures of the pyrolysis process; all the other accessories must be removed
from inside the oven.
• remove the most obvious dirt from the inside of the oven and the surface of the internal door glazing
(cleaning it by Pyrolysis would take too long);
• make sure that the oven door is firmly closed.
• When setting the cleaning cycle duration, refer to the chart below:
CLEANING DURATION LIGHT DIRT MEDIUM DIRT HEAVY DIRT
90 MIN. 135 MIN. 180 MIN.
During the first automatic cleaning cycle unpleasant smells may occur due to the normal evaporation of
oily manufacturing substances. This is an absolutely normal phenomenon which disappears after the
first cleaning cycle.
During the automatic cleaning cycle the fans make more noise because they are running at higher
speed. This is an absolutely normal function, intended to provide more effective heat dispersal. At the
end of the pyrolysis process the fans continue to run automatically for long enough to prevent
overheating of the sides of the cabinet and the front of the oven.
13.6.2 How the automatic cleaning cycle works (for models with digital programmer and
clock+programmer)
The table below shows an example of operation of the automatic cleaning cycle.
When the cycle duration is set, the thermostat light comes on but the door interlock device (and its
indicator light) is not activated.
About 2 minutes after the cleaning cycle starts an interlock device which prevents opening of the door is
tripped.
At the end of the cleaning cycle the thermostat light goes out.
The door interlock is only released later, when the temperature inside the oven drops back below 300°C.
