Possible cause and remedy
The cooktop is in Demonstration mode.
 Touch the 0 and 2 sensor controls at the same
time until  flashes alternately with  in the
timer display.
It has been operated for too long.
 You can use the cooking zone again by switching
it back on (see "Safety features - Safety switch-
off").
There is too much food in the pan.
 Start cooking at the highest power level and then
turn down to a lower one manually later on.
The pan is not conducting heat properly.
 Use a different pan which is better able to conduct
heat.
The pan is not conducting heat properly.
 Use a different pan which is better able to conduct
heat.
The pan is too large for the cooking zone.
 Use a smaller pan.
The outer ring of a double or extended cooking zone
is not switched on.
 Switch the outer ring on.
This "timing" of the element is normal. It is caused by
the electronic temperature control (see "How the
cooking zones work").
If the heating switches on and off at the highest
power level, the overheating protection has been
triggered (see "Overheating protection").
There was a power failure during operation or when
residual heat was present.
