ALARM ALERTS
In the event an operating anomaly occurs the stove starts switching off due to the alarm and informs the user of the type of
fault that has taken place via a 3 digit code which stays displayed on the rear emergency panel.
The alarm is indicated permanently by the relative 3 digit code, by a flashing red LED that lights up on the emergency panel and an
intermittent sound signal for the first 10 minutes of the alarm. Read the instructions in the following 2 paragraphs to cancel the alarm
status and restore the normal operating mode of the stove.
The following table describes the possible alarms indicated by the stove, associated to the respective code that appears on the emergency
panel and helpful tips to solve the problem.
