Warning: The surfaces of the oven become very hot during
Pyrolytic cleaning. Accordingly, keep children away
from the oven.
NOTE: before any cleaning, all accessories (wire grille, baking tray,
deep pan, grill tray, telescopic runners) must be taken out of the
oven, but only when the oven has cooled after any previous cooking
mode to avoid burns.

250°C. It is not unlocked until the temperature falls to 240°C.
The unit must remain connected to 240V mains power for the door
to release after it has cooled down.
