ERRORS/ALARMS
Appliance errors are the errors which generate the deactivation of the whole cooktop. When an appliance error
is detected, all heaters are switched off, a beep sounds (only if one or more heaters are active) and all displays
show a “F” letter and the error code alternately. While in error status all the heater keys are not operative.
Except EEPROM and microcontroller errors, all errors are recoverable. That is, when the cause of the error
disappears all displays are deactivated and the cooktop return to normal operations.
