Miele H 357 Operating Instructions Manual page 63

If, after manual cleaning, the oven is
still heavily soiled heating it to a high
temperature will help remove soiling
caused by oil and grease splashes
from the catalytic surfaces.
Before cleaning the catalytic panels
using high temperatures, make sure
that all PerfectClean surfaces have
been cleaned as previously de-
scribed. Otherwise, the high tem-
peratures can cause deposits on
PerfectClean surfaces to become
baked on and impossible to remove.
To clean using high temperatures:
Take all accessories out of the oven.
Select Fan Heat D.
Select the highest temperature set-
ting.
Run the oven for approx. 1 hour. The
length of time will depend on the level
of soiling.
Any remaining soiling will gradually dis-
appear with each subsequent use of
the oven at high temperatures.
The timer can also be used to set the
finish time (see "Switching off automati-
cally").
Should the catalytic coating on the
back panel, side liners or the roof
liner become ineffective through im-
proper use or heavy soiling, a re-
placement can be obtained from
your Miele dealer or the Miele Spare
Parts dept.
