FAULT CODES
There is a general differentiation between cooking zone- specific errors and general
errors.
Error conditions that may be definitely assigned to a cooking zone only switch off the
cooking zone.
But general errors always switch off the entire control unit. As long as there is an error
the control or the cooking zone may not be switched on again.
General errors with four cooking zones:
General errors are displayed with four cooking zone-displays for controls. Here, the
two back displays show blinking "E" and "r", and the two front displays show the two-
digit error number.
General errors with five cooking zones:
The existing fifth display is not used – the error indication is equivalent to that with four
cooking zones.
Cooking Zone- specific errors:
Are always displayed on the respective display – alternating with "E" and the one-digit
error number.
In any of these cases, it is still optionally possible to have a residual heat indication for
cooking zones with an error.
General errors basically have priority vs. Cooking zone -specific errors.
