7. ALARMS MANAGEMENT
Each error is displayed on the user interface as described in the relevant functional specifications. The errors
are also managed in the course of the test cycle or in the self-diagnosis cycle (if available). In all operating
conditions, the cooling fan remains active at the maximum speed when the door lock is active, regardless of
the type of alarm signalled.

LARM MANAGEMENT ALARM RESET
ERR1 DEFECTIVE TEMPERATURE
PROBE:
It is activated if the signal from the
probe PT1000 (converted in °C)
provides a temperature value outside
the range -20 °C / 600 °C for at least
10 seconds
Risk: high internal temperatures that
cause risk to the user's health
All heating elements OFF
- cooling fan at max speed
STOP to the cooking cycle
- Buzzer ON
-the measured temperature is
within the range for at least 10
consecutive seconds
-Placing the display in STAND-
BY (e.g. knob set to function 0)
NOTES: If the alarm is reset by
placing the oven in STAND-BY
but the alarm condition
continues, this will return as
soon as the oven goes out from
the STAND-BY condition. To
reset the alarm display is still
required to put in the oven to
STAND-BY or OFF, even if the
