Problem
The rack and other
accessories make a
noise when being
pushed into or pulled
out of the oven.
Cause and remedy
The pyrolytic resistant surface of the side runners
creates friction when accessories are being pushed
into or pulled out of the oven.
 To reduce the friction, add a few drops of heat
resistant cooking oil to some kitchen paper and
use this to lubricate the side runners. Do this after
every pyrolytic cleaning programme.
