DISPLAY OF ERRORS
Heater errors
Heater errors are the errors which generate the switch off of one or more heaters.
When a heater error is detected, the involved heaters are switched off, a beep sounds (only if one or
more heaters are active) and the displays corresponding to these heaters show a “F” letter and the error
code alternately.
While in error status the keys of the corresponding heaters are not operative.
All errors are recoverable. That is, when the cause of the error disappears the corresponding displays
are deactivated and the heaters return to normal operation.
(**) Heater switched off and locked.
(***) All the Induction heaters switched off and locked.
(****)Left or right side heaters switched off and locked.
