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 Customer Support.

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.

Getting familiar with the appliance
