en Causes of damage

]Causes of damage

Causes of damage

Caution!

Rough pan bases may scratch the hob.
Avoid leaving empty pots and pans on the hotplate.
Doing so may cause damage.
Do not place hot pans on the control panel, the
indicator area, or the hob frame. Doing so may cause damage.
Hard or pointed objects dropped on the hob may
damage it.
Aluminium foil and plastic containers will melt if
placed on the hotplate while it is hot. The use of laminated sheeting is not recommended on the hob.

Overview

You will find the most frequently caused damage in the following table:

Environmental protection en

7Environmental protection

Environmental protection

In this section, you can find information about saving energy and disposing of the appliance.

Energy-saving advice

Always use the correct lid for each pan. Cooking
without a lid uses a lot more energy. Use a glass lid to provide visibility and avoid having to lift the lid.
Use pans with flat bases. Bases that are not flat use
a lot more energy.
The diameter of the pan base must match the size of
the hotplate. Please note: pan manufacturers usually provide the diameter for the top of the pan, which is usually larger than the diameter of the pan base.
Use a small pan for small amounts of food. A large
pan which is not full uses a lot of energy.
Use little water when cooking. This saves energy and
preserves all the vitamins and minerals in vegetables.
Select the lowest power level to maintain cooking. If
the power level is too high, energy is wasted.

Environmentally-friendly disposal

Dispose of packaging in an environmentally-friendly manner.
This appliance is labelled in accordance with European Directive 2012/19/EU concerning used electrical and electronic appliances (waste electrical and electronic equipment ­WEEE). The guideline determines the framework for the return and recycling of used appliances as applicable throughout the EU.

fInduction cooking

Induction cooking

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 hob increases or
decreases the heat supply as soon as the user changes the setting. The induction hotplate stops the heat supply as soon as the cookware is removed from the hotplate, without having to switch it off first.

Cookware

Only use ferromagnetic cookware for induction cooking,
such as:
Cookware made from enamelled 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
~ "Cookware check".
To achieve a good cooking result, the ferromagnetic
area on the base of the pan should match the size of
the hotplate. If a hotplate does not detect an item of
cookware, try placing it on another hotplate with a
smaller diameter.
FP
FP
FP
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.
7
en Induction cooking
The ferromagnetic area will also be reduced if the
material from which the base of the cookware is made contains aluminium, for example. This may mean that the cookware will not become sufficiently hot or even that it will not be detected.

Unsuitable pans

Never use diffuser hobs or pans made from:
common thin steel
glass
earthenware
copper
aluminium

Properties of the base of the cookware

The material(s) from 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 three­layer 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.

Pan detection

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

Absence of pan or unsuitable size

If no pan is placed on the selected hotplate, or if it is made of unsuitable material or is not the correct size, the power level displayed on the hotplate indicator will flash. Place a suitable pan on the hotplate to stop the flashing. If this takes more than 90 seconds, the hotplate will switch off automatically.

Empty pans or those with a thin base

Do not heat empty pans, nor use pans with a thin base. The hob 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 base of the pan could melt and damage the glass on the hob. In this case, do not touch the pan and switch the hotplate off. If it fails to work after it has cooled down, please contact the Technical Assistance Service.

Chef's recommendations

Recommendations

When heating up puree, cream soups and thick
sauces, stir occasionally.
Set heat setting 8 to 9 for preheating.
When cooking with the lid on, turn the heat setting
down as soon as steam escapes between the lid and the cookware. Steam does not need to escape for a good cooking result.
After cooking, keep the lid on the cookware until you
serve the food.
To cook with the pressure cooker, observe the
manufacturer's instructions.
Do not cook food for too long, otherwise the
nutrients will be lost. The kitchen clock can be used to set the optimum cooking time.
For a more healthy cooking result, smoking oil
should be avoided.
To brown food, fry small portions in succession.
Cookware may reach high temperatures while the
food is cooking. We recommend that you use oven gloves.

Noises

Why I can hear noises while I'm cooking?
Noises may be generated while using the hob depending on the base material of the cookware. These noises are a normal part of induc­tion technology. They do not indicate a defect.
Possible noises:
A low humming noise like the one a transformer makes:
Occurs when cooking at a high heat setting. The noise disappears or becomes quieter when the heat setting is reduced.
Low whistling noise:
Occurs when the cookware is empty. This noise disappears when water or food is added to the cookware.
Crackling:
Occurs when using cookware made from different layers of material or when using cookware of different sizes and different materials at the same time. The loudness of the noise can vary depending on the quantity of food being cooked or the cooking method.
High-pitched whistling noises:
Can occur when two hotplates are used at the highest heat setting at the same time. The whistling noises disappear or become quieter when the heat setting is reduced.
Fan noise:
The hob is equipped with a fan that switches on automatically at high temperatures. The fan may continue to run even after you have switched off the hob if the temperature detected is still too high.
