If an E Ö and a series of numbers appear in the display panel, there is a fault in the
electronic system. Turn the appliance off and back on at the fuse or circuit breaker.
Call technical assistance if the same display appears again.
If an F and a number flash in alternation on the displays, your appliance has
detected a fault. Refer to the following table for possible remedies.
Fault
The cooking sensor is
defective.
The element is too hot
and has turned off.
The cooking sensor is
too hot.
The pot or pan is too
close to the control
panel.
The element has been
in constant operation,
at high power, for too
long.
A gap may form between the countertop and the cooktop. For this reason, there is a
flexible seal all the way around the cooktop.
Due to the characteristics of the material, there can be irregularities in the glass
ceramic surface. Because of the mirror-smooth surface of the cooktop, it is
possible for even the smallest of bubbles, less than 1mm in diameter, to be visible.
They are not detrimental either to the functionality or the durability of the glass
ceramic cooking surface.
Induction heating technology is based on the creation of electromagnetic fields that
cause heat to be created directly on the pan base. Depending on the construction
of the cookware, certain noises or vibrations may be created, such as the following:
This occurs when cooking at a high power. The cause of this is the amount of
energy which is transmitted from the appliance to the cookware. This sound
disappears or becomes quieter when the power is turned down.
This occurs when the cookware is empty. This sound disappears when water or
food is added to the cookware.
This noise occurs when cookware is used which consists of layers of different
materials. The noise is caused by vibrations in the joint faces between the different
layers. This noise comes from the cookware. It may change depending on the
amount and type of food being cooked.
Measure
Lower the cooking sensor. When the visual
indication disappears, you can cook again
without the cooking sensor.
Contact technical service.
Remove the pans from the elements. F2
disappears when you press the display if the
element has cooled sufficiently. Wait a few
minutes until the elements have cooled down
slightly. If F2 appears again after the element is
turned back on, the cooktop is still too hot. Turn
off the elements and allow them to cool further.
Remove the pan and press the cooking sensor.
Press any symbol on the cooktop. The F3
indicator disappears if the cooking sensor has
cooled enough.
Verify that the pot or pan is properly positioned
on the element.
Verify that nothing hot is on the control touch key
panel.
The automatic shut off was activated.
To continue cooking, press any symbol.
