Make sure the base of the pan is smooth, sits flat against the glass and is the
same size as the cooking zone. Use pans with a diameter as large as the graphic
of the zone selected. Using a pot slightly wider will result in the energy used at
its maximum efficiency. If you use a smaller pot the efficiency could be less than
expected.
Pots less than 140 mm in diameter could be undetected by the hob. Always
centre your pan on the cooking zone.
Always lift pans off the induction hob – do not slide as they may scratch the
glass.
