Appliance errors are the errors which generate the deactivation of the whole
hob.
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 hob
returns to normal operation.
