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.
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.
The element is too hot and has
turned off.
The touch control zone is too hot.
The element was in continuous use
for too long.
Remove the pans from the elements.
when you press the display, if the element has
cooled down sufficiently. Wait a few minutes until the
element has cooled down a bit. If
after the element is turned back on, the cooktop is
still too hot. Turn off the elements and allow them to
cool further.
Make sure that cookware is properly positioned on
the element, and no hot objects are in contact with
the touch control zone. Wait a few minutes until the
touch control zone has cooled down. If
after you turn on the appliance, call Technical Assis-
tance Service.
The automatic time limitation has been activated.
Touch any key. You can now turn on the heating ele-
ment immediately.
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.
