1 Safety precautions
• Do not climb onto the appliance.
• Do not put hot cookware on the hob frame in order not to damage the
silicon joints.
• Always ensure that the base of the cookware and the surface of the hob
are clean and dry before use.
• Do not cut or prepare food on the surface. Avoid impact with hard objects.
Do not drag cookware across the surface.
• Take particular care that sugary foods or juices do not get onto the hot

do get onto hot cooking zones, clean away immediately (while still hot) with
a scraper for glass ceramic hobs.
• Do not leave the appliance unattended when in use.
• Keep animals away from the appliance.
• Induction hobs produce a high frequency magnetic field around the
cooking zones. Standing near the cooking zones can under unfavourable
circumstances have an adverse effect on or affect the working of
pacemakers, hearing aids or metallic implants.
• Tests have shown that under normal circumstances there is no risk to
cardiac pacemaker users. If, as the user of a cardiac pacemaker (or a
hearing aid or another type of implant), you would like to be reassured that

3.3How induction hobs function
Induction hobs work very differently from conventional hobs or hot plates. The
induction coils under the glass ceramic plate produce a rapidly changing
magnetic field which directly heats up the magnetic base of the cookware.
The glass ceramic plate is only warmed by the hot cookware.
Removing the cookware from the cooking zone immediately interrupts the
supply of energy.
Induction hobs are:
– quick reacting
– finely adjustable
–powerful
– energy-efficient
– safe.
Induction hobs can only be used with cookware with a magnetic base.
3.4Pan detection
Each cooking zone is equipped with pan detection.
This detects suitable induction compatible cookware with a magnetic base.
• If the cookware is removed during operation or if the cookware used is
unsuitable,
– illuminates in the power level display.
• If no suitable cookware is placed on the cooking zone before the pan
detection time (10 minutes) elapses,
– the cooking zone switches off
– the display changes from to
– If no other cooking zone is in use, the appliance switches off automati-
cally after 10 seconds.

3.5Cookware
Suitable cookware
Only cookware with a magnetic base is suitable for use with the induction
hob.
This can be tested in the following ways:
• A magnet sticks anywhere on the base of the cookware.
• On the hob, the power level set illuminates and not .
Do not heat any unsuitable cookware using aids such as metal rings
and the like. This can damage the hob.
Energy-efficient cooking
For maximum energy efficiency and even heat distribution note the following:
• The base of the cookware must be clean, dry and smooth.
• The diameter of the base of the cookware should as far as possible corre-
spond to the diameter of the cooking zone.
• Centre the cookware in the middle of the cooking zone.
•Use a well-fitting lid.
• Match the diameter of the cookware to the quantity of food to be cooked.
Coated cookware
• Coated cookware when empty may never be heated at a higher power
level than .
– The coating may otherwise become overheated and damaged.
• For frying, do not use a higher power level than 9.
Never use PowerPlus with coated frying pans.

Noise during cooking
Cookware can make noise during cooking. This does not indicate any
malfunction, nor does it affect the functioning of the appliance in any way.

5Care and maintenance
Clean the appliance when it has cooled down, as otherwise it could
be a burn hazard.
5.1Cleaning
Always clean the hob after use. This prevents food residues from burning on.
Dried-on or burned-on food residue is harder to clean off.
Use of improper cleaning techniques can result in damage to the markings
or surface.
Avoid cleaning the surface of the glass ceramic hob with abrasive
cleaning agents, scouring pads, wire wool, etc. which can damage the
surface.
➤ Use only a soft cloth or sponge with water and a suitable detergent for
cleaning everyday soiling. Always follow the detergent manufacturer's
instructions for use. Using a detergent with a protective additive is
recommended.
➤ Remove stubborn soiling, e.g. boiled-over milk, while still warm using a
glass ceramic hob scraper.
Always follow the scraper manufacturer's instructions for use.
➤ Foods with a high sugar content, e.g. marmalade, that boil over should be
removed while still hot using a glass ceramic hob scraper. The surface of
the glass ceramic hob could otherwise become damaged.
➤ Remove melted plastic while still warm using a glass ceramic hob scraper.
The surface of the glass ceramic hob could otherwise become damaged.
➤ Remove limescale stains when cool with a small amount of limescale
remover (e.g. vinegar, lemon juice, descaler). Then wipe clean with a damp
cloth.
