Causes of damage

NOTICES

• Scratches on glass ceramic surface: Cookware with rough bottoms will scratch the glass ceramic surface.
• Salt, sugar and sand: Salt, sugar or grains of sand will scratch the glass ceramic surface. Never use the cooktop as a working surface or for setting things down.
• Overheated cookware: Avoid heating pots or pans that are empty.
• Hot cookware: Never set down hot pans and pots on the control panel or frame. This may cause damage.
• Hard and sharp objects: Hard or sharp objects falling on the cooktop may damage it.
• Boiled-over food: Sugar and products containing sugar may damage the cooktop. Immediately eliminate spills of these products with a glass scraper.
• Foils and plastics: Aluminum foil and plastic will melt on the hot cooking zones. Stove protective film isn't suitable for your cooktop.
• Unsuitable cleaning agent: Shimmering metallic discolorations on the glass ceramic surface result from the use of inappropriate cleaning agents and abrasion from cookware.

Protecting the environment

Energy-saving advice

• Always place a fitting lid on cookware. Cooking with an uncovered pan will result in a four-fold increase in energy use. Use a glass lid to provide visibility and avoid having to lift the lid.
• Use cookware equipped with a solid, flat bottom. Curved pan bases increase energy consumption.
• The diameter of the pan base must match the size of the element. If not, energy may be wasted. Note: The manufacturer normally indicates the pan's upper diameter. This is normally greater than the diameter of the pan's base.
• Choose cookware of a size suited to the amount of food you are going to cook. A large pan that is only half full will use a lot of energy.
• Use a small amount of water when cooking. This saves energy, and vegetables retain a larger percentage of their vitamins and minerals.
• Select a lower power level.

Cooking with Induction

Advantages of induction cooking

Induction cooking is very different from traditional cooking methods, as heat builds up directly in the item of cookware. This offers numerous advantages:

• Saves time when boiling and frying.
• Saves energy.
• Easier to care for and clean. Spilled food does not burn on as quickly.
• Heat control and safety – the cooktop increases or decreases the heat supply as soon as the user changes the setting. The induction element stops the heat supply as soon as the cookware is removed from the element, without having to switch it off first.

Cookware

Only use ferromagnetic cookware for induction cooking, such as:

• Cookware made from enameled steel
• Cookware made from cast iron
• Special induction-compatible cookware made from stainless steel.

To check whether your cookware is suitable for induction cooking, refer to the section on "Suitability test of cookware".

To achieve a good cooking result, the ferromagnetic area on the base of the pan should match the size of the element. If a element does not detect an item of cookware, try placing it on another element with a smaller diameter.

Some induction cookware does not have a fully ferromagnetic base:

• If the base of the cookware is only partially ferromagnetic, only the area that is ferromagnetic will heat up. This may mean that heat will not be distributed evenly. The non-ferromagnetic area may not heat up to a sufficient temperature for cooking.

• The ferromagnetic area will also be reduced if the material of which the base of the cookware is made contains aluminum, for example. This may mean that the cookware will not become sufficiently hot or even that it will not be detected.

Unsuitable cookware

Do not ever use adapter plates for induction or cookware made of:

• Traditional stainless steel
• Glass
• Clay
• Copper
• Aluminum

Properties of the base of the cookware

The material(s) of which the base of the cookware is made can affect the cooking result. Using pots and pans made from materials that distribute heat evenly through them, such as stainless-steel pans with a three-layer base, saves time and energy. Use cookware with a flat base; if the base of the cookware is uneven, this may impair the heat supply

No pan or improper size

If no pan is placed on the selected element, or if it is made of unsuitable material or is not the correct size, the power level displayed on the element indicator will flash. Place a suitable pan on the element to stop the flashing. If you take longer than 90 seconds to place a suitable pan on the element, it will automatically turn off.

Empty pans or pans with a thin base

Do not heat up empty pans, or use pans with a thin base. The cooktop is equipped with an internal safety system. However, an empty pan may heat up so quickly that the automatic switch off" function may not have time to react and the pan may reach very high temperatures. The pan base could melt and damage the cooktop glass. In this case, do not touch the pan and switch the cooktop off. If the cooktop fails to work after it has cooled down, please contact the technical service.

Pan detection

Each element has a lower limit for pan detection. This depends on the diameter of the ferromagnetic area of the cookware and the material of which its base is made. For this reason, you should always use the element that best matches the diameter of the base of the pan.

Automatic detection in double and triple cooking zones

These cooking zones can detect cookware of different sizes. Depending on the material and the properties of the cookware, the cooking zone automatically activates the singe, double or triple cooking zone, supplying the proper power to obtain good cooking results.
