. . . spots like rust appear on the
catalytic surfaces
When roasting on the rack, the
circulating air sometimes picks up
spices, which are then deposited on
the oven interior walls. These residues
are not removed by catalytic cleaning,
and should be removed while fresh with
a mild solution of hot water and
washing up liquid applied with a soft
brush.
. . . there has been a power cut and

. . . an "F" and a number appear in
the display.
This combination indicates a fault.
– "F55":
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 exceedingly
long period. The length of time
depends on the oven function
selected.
The oven can be used again immedi-
ately by simply turning the
programme selector to "0" and
entering the process again.
– If any other fault message appears
in the display, you should call the
Service Dept.
