Automatic turning-off
For safety reasons, the power supply to the hob cuts out after a certain time (1.5 to 6 hours). The higher the heat of the hotplate, the earlier the power is cut:

Once the time for one hotplate has expired, all hotplates in use then cut out. A line appears in the control window for these hotplates until you have reset the controls.
Choosing suitable pans
Greater attention needs to be paid to the type and condition of pans used on ceramic hobs than it does with radiant hobs. Here are some points to remember: � Check the pan bases. Bases which are convex (curve outwards) will tend to spin on the hob and will not conduct heat very well. � Aluminium is a good conductor of heat, but it can leave silver-coloured stains on the hob. You can remove these stains with the hob cleaner supplied with the cooker. � Glass vessels and enamelled bases with a rough pattern will � if pulled back and forth across the surface � cause greater wear on the hob than other materials. To save you time and therefore energy, the contact surface of the pan base should: � be at least as large as the hotplate. If the base is smaller than the hotplate, any spillages are quite likely to burn onto the hob. � be smooth or have a fine pattern � be flat. It takes longer to heat a pan with a base which curves in or outwards too much. When you are buying new pans, it is advisable to choose stainless steel ones with sandwich-type bases (i.e. layers of different metals).
