Noise emission
An induction hob can make noises when in
use. All these noises are neither the result
of technical errors nor are they the result of
poor quality. They are related to the induction
technology and do not negatively affect the
cookware or hob.
Possible noises:
– Low humming noise like a transformer
This noise can occur when a high power
level is used. The cause of this is that a
large amount of energy is transferred from
the hob to the cooking device. The noise
disappears or dissipates as soon as the
power setting is reduced.
– Quiet whistling
Quiet whistling can occur when empty
cookware is placed on a cooking zone.
It disappears as soon as water or food is
placed in the cooking device.
– Crackling
This noise can occur when cooking appli-
ances have layers made of different mate-
rials. The noise is caused by vibrations at
the joints of the different material layers.
This noise occurs in the cooking device
itself. The sound may change depending
on the type and quantity of the food being
cooked.
– High-pitched whistling sounds
These noises mainly occur when cook-
ware made of different layers of material
are used on two adjacent cooking zones
at maximum power. The noise disappears
or dissipates as soon as the power setting
is reduced.
– Whirring
Depending on the pot, volume or temper-
ature, a slight whirring noise may occur
when cooking on the induction hob.
With some pots, this noise may only arise
while they are heating up, and with others,
only once they are warm; in some, the
noise will arise only when the fill level is
very low and in others, only when they are
completely filled. The noise may be contin-
uous or may occur at intervals. It can occur
in the same pot on one cooking zone, but
not on another. Even when using the same
pot on the same cooking zone, the noise
may not occur every time. It may occur
when a specific pot is in a certain position
on the cooking zone – and may not occur
again the next time.
– Fan noise
A certain ambient temperature must not be
exceeded in order for the electronics inside
the hob to work properly. For this reason
the hob is equipped with a fan, which – in
this hob – switches on automatically when
one of the cooking zones is activated, and
which continues to run for some time after
the hob has been switched off.
This noise is likewise completely normal
and is not an indication of a technical fault
or of poor product quality.
