. . . cakes or biscuits are unevenly
browned.
There will always be a slight uneven-
ness. Product information sheets give a
percentage result for standard brown-
ing tests. These refer to results for one
tray.
If browning is very uneven, check
– when baking with
Fan Heat
D
:
whether the temperature was set too
high,
whether the roasting filter was in
place,
whether the correct runner height
was used.
– when baking with
Conventional
A
:
the colour and composition of the
baking tins being used. Light col-
oured, shiny, or thin walled tins are
less suitable,
whether the correct runner height
was used.
. . . spots like rust appear on cata-
lytic surfaces.
When roasting on the rack, the circulat-
ing air sometimes picks up spices,
which are then deposited on the oven
interior walls. Such residues are not
removed by catalytic cleaning, they are
best removed while fresh with a mild
solution of hot water and washing up
liquid and a soft brush.
. . . there has been a power cut and
"12:00" and the triangle
V
are flash-
ing underneath the
m
symbol.
All pre-set times are deleted as a result
of the power failure.
Enter the time of day again, and any
other pre-set data.
. . . "F" and a number appear in the
display.
This combination indicates a fault.
–
"F 54"
: the roast probe is defective.
Remove the probe from its socket
and the message will disappear.
–
"F 55"
: the oven has automatically
switched itself off during use. This is
a safety feature to protect the oven if
it has been operating for an exceed-
ingly long period. The length of time
depends on the oven function se-
lected.
The oven can be used again immedi-
ately by simply turning the oven func-
tion selector to "0" and then entering
the process again.

If
any other fault message
appears in
the display, this will need a service
visit.
