When the SD card integrated in the control panel is
corrupted the oven will show a different set of alarms:
■ AF27
AF23.01

When the oven triggers the AF23 alarm, the
display shows you a string of values like X|Y|Z|
W which mean:
■ X = temperature of the cooking chamber when
the alarm triggered;
■ Y = number of times the oven successfully ignited
at the first ignition attempt;
■ Z = number of times the oven successfully ignited
at the second ignition attempt;
■ W = number of times the oven successfully ignited
at the third ignition attempt.
The oven could trigger an AF23.00.
