The oven lighting
switches off after a
short time.
136
Cause and remedy
The wrong temperature or shelf level was selected.
 There will always be a slight unevenness. If the
unevenness is pronounced, check that the correct
temperature and shelf level have been selected.
The material or colour of the baking tin is not suitable
for the oven function.
 When using Conventional heat  use matt, dark
coloured pans. Light coloured, shiny pans will not
produce as desirable results.
The catalyser has been set at too high a level. This
can lead to an uneven browning result on more
delicate food such as sponge cakes.
 Set the odour reduction catalyser to a lower level
or switch it off (see "Settings - Catalyser").
The oven lighting is set to switch off after 15 seconds
(default setting). You can change the default setting
for this (see "Settings - Lighting").
