u_ is displayed for a cooking zone on the induction cooktop.
Place a suitable item of cookware on the cooking zone that you have switched on.
Suitable cookware is made of:
stainless steel with a magnetic base
enameled steel
cast iron
Additional information can be found in the linked video.
Unsuitable cookware is made of:
stainless steel without a magnetic base
aluminum, copper
glass-ceramic/ceramic, earthenware, stoneware
If you are unsure whether a pot or pan is suitable for use on an induction cooktop, you can carry out the test described below. Hold a magnet to the base of the pan. If the magnet sticks, the dishware is suitable.
To ensure optimum use of the cooking zone, select a pot or pan that is large enough to fill the space between the innermost and outermost cooking zone markings. If the pan is smaller than the innermost marking, the induction process will not work. The cooking zone will behave as if no cookware has been placed on it.
