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.
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.
If the only hotplate being used is the flexible cooking zone, larger cookware that is particularly suited to this zone can be used. You can find information on positioning cookware in the section on "Flex Zone".
Induction cooking
8 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 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
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.
You can find information on the dimensions and power of the hotplates in Page 2
Note: . Depending on the appliance model, individual details and colours may differ.
Touch controls
Touching a symbol activates the associated function.
Notes
■ Always keep the control panel clean and dry.
Moisture reduces its effectiveness.
■ Do not place any cookware near the indicators or sensors. The electronics could overheat.
The hob has a residual heat indicator for each hotplate. This indicates that a hotplate is still hot. Do not touch a hotplate while the residual heat indicator is lit up.
The following indicators are shown depending on the amount of residual heat:
■ Display 
: High temperature
■ Display 
: Low temperature
If you remove the cookware from the hotplate during cooking, the residual heat indicator and the selected heat setting will flash alternately.
When the hotplate is switched off, the residual heat indicator will light up. Even after the hob has been switched off, the residual heat indicator will stay lit for as long as the hotplate is still warm.
This chapter explains how to set a hotplate. The table shows heat settings and cooking times for various meals.
The main switch is used to switch the hob on and off.
To switch on: Touch the 
symbol. An audible signal sounds. The indicator next to the main switch and the hotplate indicators 
light up. The hob is ready to use.
To switch off: Touch the symbol until the indicator goes out. All hotplates are switched off. The residual heat indicator remains lit until the hotplates have cooled down sufficiently.
Notes
■ The hob switches off automatically if all hotplates have been switched off for more than 20 seconds.
■ The selected settings are stored for four seconds after the hob has been switched off. If you switch it on again during this time, the hob will operate using the previously stored settings.
Use the 
and 
symbols to select the required heat setting.
Heat setting 
= lowest setting.
Heat setting

Notes
■ If no pan has been placed on the hotplate, the selected power level flashes. After a certain time has elapsed, the hotplate switches off.
■ If a pan has been placed on the hotplate before switching on the hob, it will be detected within 20 seconds of pressing the main switch and the hotplate will be selected automatically. Once detected, select the power level within the next 20 seconds or the hotplate will switch off. If more than one pan is placed on the hob, only one will be detected when switching it on.
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.

Notes
■ The flexible cooking zone only counts as a single hotplate; place no more than one item of cookware on it.
■ If the diameter of the hotplate used is much smaller than the diameter of the cookware, only the middle of the cookware can be expected to heat up. This may result in the cooking results not being as good as expected or being less than satisfactory.
■ You can find information on this function in the section on “Basic settings”
■ You can find information on the type, size and positioning of the cookware in the sections on “Induction cooking” and “Flex Zone”
You can use the power manager to set the total power of the hob.
The hob is preset at the factory. Its maximum performance is specified on the rating plate. You can use the power manager to change the value in accordance with the requirements for the relevant electrical installation.
In order not to exceed this set value, the hob automatically distributes the power available between the cooking zones that are switched on.
As long as the power manager function is activated, the output of a cooking zone may temporarily fall below the nominal value. If a cooking zone is switched on and the power limit is reached, ¬ appears in the heat setting display for a short time. The appliance automatically regulates and selects the highest possible power level.
For more information about how the total power of the hob is changed, see section “Basic settings”
Suitable maintenance and cleaning products can be purchased from the after-sales service or in our e-Shop.
Cleaning
Always clean the hob after cooking. This will prevent food deposits from becoming burned on. Only clean the hob after the residual heat indicator has gone out.
Clean the hob with a damp dish cloth and dry it with a cloth or towel to prevent limescale build-up.
Only use cleaning agents that are suitable for this type of hob. Observe the manufacturer's instructions on the product packaging.
Never use:
■ Undiluted washing-up liquid
■ Cleaning agents designed for dishwashers
■ Abrasive cleaners
■ Harsh cleaning agents, such as oven spray and limescale remover
■ Scouring pads
■ High-pressure cleaners or steam jet cleaners
Stubborn dirt is best removed with a glass scraper, available from retailers. Observe the manufacturer's instructions.
You can obtain a suitable glass scraper from customer services or through our online shop.
Using a special sponge for cleaning glass-ceramic hobs achieves a great cleaning result.
Note: Do not use any cleaning agents while the hob is still hot. This may mark the surface. Make sure that any residue left by cleaning agents is removed.
To prevent damage to the hob surround, observe the following instructions:
■ Only use warm soapy water
■ Wash new dish cloths thoroughly before use.
■ Do not use harsh or abrasive cleaning agents.
■ Do not use a glass scraper or sharp objects.
Usually, faults are small matters that are easy to eliminate. Please read the information in the table before calling the after-sales service.
