Lift up the edge of the lower heating
element a few centimetres and clean
the bottom.
Put the pizza plate support back in
place, pushing it in until it hits the back
of the oven, and push it down so that
the heating element plate is embedded
into the base itself.
When the operation is complete, damp parts should be dried thoroughly.
10.6 Removing guide frames
90
Instructions for the user
Removing the guide frames makes it easier to
clean the side parts of the oven, and it also
needs to be done whenever the automatic
cleaning cycle is used (only available on some
models).
• To remove the guide frames, pull the
frame towards the inside of the oven to
unhook it from its housing A, then slide it
out of the seats at the back B.
• When cleaning is complete, repeat the
above procedures in reverse order to put
the guide frames back in.
