These types of noise can be described
as follows:
Light buzz (like the noise made by a
transformer)
This noise is produced when cooking
with a high level of heat, and it is de-
termined by the amount of energy trans-
ferred by the hob to the pans. The noise
will stop or decrease when the heat
level is reduced.
Light whistle
This noise is produced when the pot or
pan is empty, and stops as soon as it is
filled with water or food.
Crackle
This noise occurs with pans made from
layers of numerous different materials,
and is caused by vibration of the sur-
faces where the different materials
meet. The noise comes from the pans,
and may vary according to the quantity
of food and preparation method being
used.

when these are used at maximum level
and on two cooking areas. The noise
will stop or decrease when the heat
level is reduced.
Fan noises
For the electronic system to operate
correctly, the temperature of the cooker
hob must be regulated. To do this, the
hob is equipped with a cooling fan that is
activated to reduce and regulate the
temperature in the electronic system.
The fan may continue to operate after
the appliance has been turned off, if the
temperature of the cooker hob is still de-
tected to be too high.
Rhythmic sounds like a clock ticking
This noise only occurs when at least
three cooking areas are operating, and
it disappears or decreases when some
of them are turned off.
The noises described are a normal fea-
ture of induction technology and are not
to be considered as defects.
Possible causes of the error
LIN cable damaged or badly connec-
ted to the hood electronic board
Continuous key activation detected.
Water or pan placed on the control
panel.

tronic parts is too high.
