Normal Operating Noises Of The Cooktop - Gaggenau CI 491 602 Notice D'utilisation

Indicator Malfunction
—‚
Supply voltage outside normal operating
limits.
—ƒ / —„
The element has overheated and has
switched off in order to protect its cook-
ing surface.
Do not place hot pans on the control panel.
Notes
‒ Glass ceramic may have uneven areas on the
surface due to the nature of the material itself.
Because of the mirror-like finish on the cooking
surface, even extremely small bubbles less than 1
mm in diameter may be visible. These bubbles will
not have any adverse effect on the operation of
the cooktop nor on the durability of the glass
ceramic cooking surface.
‒ Depending on the countertop that is present in
the kitchen, an uneven gap between the cooktop
unit and the countertop can occur. For this
reason, a flexible seal is provided around the
entire cooktop unit.
Normal operating noises of the
cooktop
Induction technology is based on the creation of
electromagnetic fields. They may generate heat
directly on the bottom of the cookware. Pots and pans
may cause a variety of noises or vibrations depending
on the way they've been manufactured. These noises
are described as follows:
Low humming (like a transformer)
This noise is produced when cooking at a high heat
level. It is based on the amount of energy transferred
from the cooktop to the cookware. The noise ceases
or quiets down when the heat level is reduced.
Quiet whistling
This noise is produced when the cooking vessel is
empty. It ceases once water or food is placed in the
vessel.
Solution
Please contact your local electricity company.
Wait until the electronic system has cooled down sufficiently
before switching it back on.
Crackling
This noise occurs with cookware comprised of various
materials layered one upon the other. It's caused by
the vibrations of the surfaces where different
materials meet. The noise occurs on the cookware and
can vary depending on the amount and method of
preparation of the food.
Loud whistling
This noise occurs with cookware comprised of
different materials layered one upon the other, and
when they are additionally used at maximum output
and also on two cooking zones. The noise ceases or
quiets down when the heat level is reduced.
Fan noises
For proper operation of the electronic system, it is
necessary to regulate the temperature of the cooktop.
For this purpose, the cooktop is equipped with a
cooling fan, which is activated to reduce and regulate
the temperature of the electronic system. The fan may
also continue to run after the appliance is turned off if
the detected temperature of the cooktop is still too
hot after turning it off.
The noises described are a normal element of the
described induction technology and shouldn't be
regarded as defects.
