SAFETY DEVICES
CONTROL AND SAFETY SYSTEMS OF THE OVEN
- PROTECTION OF THE AUXILIARY ELECTRIC CIRCUIT.
Controlled by a fuse (6.3 A) on the auxiliary circuit line.
- MOTOR-DRIVEN FAN PROTECTION
The motor-driven fan has an internal overload switch that automatically trips if the windings overheat. Reset is automatic
when normal temperature returns. The likely causes of this safety device tripping comprise: rubbing or stiffening of the motor
fan-pin system, excessive uneven scale on the blade, etc.
- OVEN DOOR MICROSWITCH.
The oven switches off automatically when the oven door is opened.
- SAFETY THERMOSTAT.
This device trips if there is any trouble with the oven temperature control thermostat so the admitted limits are not exceeded.
In the event of a failure, in order to restore operation, take off the control panel on the right and press the red push-button of
the safety thermostat. Notify a technical service centre.
STEAM GENERATOR SAFETY THERMOSTAT
This trips if the temperature in the boiler exceeds a certain level due to a shortage of water and when the two water level
sensors no longer react. One cause may be scale on the water level sensors.
In the event of a failure, in order to restore operation, take off the panel on the right and press the red push-button of the safety
thermostat. Notify a technical service centre.
SYSTEMS CONTROLLING THE LEVEL OF WATER IN THE BOILER
This check is made by the electronic card that controls two sensors: the maximum and minimum sensors. The advantage here
is of disconnecting the power supply to the boiler heating element until the water reaches the necessary level, avoiding
possible failure due to the boiler overheating because of a lack of water.
7.3
SWITCHING OFF IN THE EVENT OF EQUIPMENT FAULTS
IMPORTANT: YOU MUST SWITCH THE OVEN OFF WITH THE MULTI-POLAR SWITCH UPSTREAM.
CLOSE THE WATER SHUT-OFF VALVE.
REQUEST AN AUTHORIZED TECHNICIAN FROM YOUR DEALER.
A)
Replacing the light bulb illuminating the cooking chamber (see above paragraph).
B)
Waste water/cooking vapour outlet clogged.
If the waste water or cooking vapour outlet gets clogged, you need to:
- Check that the outlet is clear as far as the open siphon.
- Rinse thoroughly with running water and check it flows off freely when drained.
C)
The motor-driven fan stops.
There may be two causes:
- The microswitch is defective, or set wrongly, or the door is not properly shut.
- The overload switch has tripped, cutting off the power supply in the event of overheating.
Resetting is automatic.
If the motor stops often, request a skilled technician to find the causes of the trouble.
D)
Oven heating fails to work.
- Check whether the door is shut and the fan turns.
- If the heating fails to work, the safety thermostat of the cooking chamber has probably tripped.
In the event of overheating >350°C in the oven, the safety thermostat in the cooking chamber cuts off the
power supply.
- The safety thermostat in the cooking chamber can only be reset by a technician authorized by the dealer.
7.3.1
STEPS TO TAKE IF THE OVEN IS NOT TO BE USED FOR A LENGTHY PERIOD.
After thoroughly cleaning the oven both inside and outside:
- Open the multi-polar switch contacts to cut off the power supply.
- Shut the water valve upstream from the oven.
- Give all the steel surfaces a good wipe over with a cloth lightly soaked in Vaseline oil in order to apply a
protective film.
- Leave the oven door half open.
- Talcum powder on the gaskets.
