The storage tray under the oven can be taken out completely for easier
cleaning.
Pull it out all the way and lift it upwards at the front (like a drawer).
8.4 Door glazing
The glass in the door should always be kept thoroughly clean. Use
absorbent kitchen roll; in case of stubborn dirt remove with a damp
sponge and an ordinary detergent.
8.5 PYROLYSIS: Automatic oven cleaning (main oven only)
Pyrolysis is an automatic high-temperature cleaning procedure which
causes dirt to dissolve. Thanks to this process, it is possible to clean the
inside of the oven very easily.
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.
Before starting the automatic cleaning cycle, make sure that the oven does
not contain any foods or large spills from previous cooking operations.
During the pyrolysis cycle, a door locking device makes it impossible to
open the door.
