or for uses other than those for
which this appliance is
inten e .
When using your appliance, follow
basic safety precautions including
the following:
Installation
Be certain your appliance is
properly installed and grounded by
a qualified technician in accordance
with national and local safety
regulations. The manufacturer cannot be
held responsible for damage caused by
an incorrect installation or connection.
To guarantee the electrical safety

by a qualified electrician.
The manufacturer cannot be held
responsible for damages caused by the
lack, or inadequacy of, an effective
grounding system.
Do not connect the appliance to
the main electrical supply using an
extension cord. Extension cords do not
meet the safety requirements of this
appliance.
Before servicing, disconnect the
power supply by either shutting off
the power main or manually "tripping"
the circuit breaker.
IMPORTANT SAFETY INSTRUCTIONS
3

Do not install the cooktop directly
above a dishwasher, refrigerator or
freezer. Heat radiated by the cooktop
may damage them.
If the cooktop is installed above an
oven, keep the cooktop’s power
cord from contacting the oven.
Because of the heat radiated it is
not recommended to install the
cooktop above a drawer. It should only
be installed above a cabinet base unit
with a dummy drawer front and an
additional protective base between the
appliance and the cabinet.
This equipment has not been
designed for maritime use or for
use in mobile installations such as
aircraft or recreational vehicles.
However, under certain circumstances
it may be possible for an installation in
these applications. Please contact the
nearest Miele Dealer or the Miele
Technical Service Department with
specific requirements.
Use
Do not use the appliance until it is
properly installed in the countertop.
This appliance is equipped with an
overheating protection feature.

or heat the room. Due to the high
temperatures radiated objects left near
the appliance could catch fire.
IMPORTANT SAFETY INSTRUCTIONS
4

Protection from amage
Do not drop anything on the
ceramic surface of the cooktop.
Although the ceramic glass is shock
and scratch resistant, it is not shock or
scratch proof.
Do not use pots or pans with
pronounced edges or ridges on
the ceramic cooktop. These could
scratch the cooktop permanently. See
"Selecting Cookware" for more
information. Grains of salt and sand can
also scratch.Make sure that the bases
of any pots and pans are clean, free of
any fat or oils and are dry.
Do not allow either solid or liquid
sugar, pieces of plastic or
aluminium foil to fall on the burners
when they are hot. If these residues are
allowed to cool on the ceramic surface
pitting or even cracking could occur.
Any spills should be removed as
quickly as possible to prevent them
from burning on and becoming difficult
to remove.
Do not use a steam cleaner to
clean the appliance. Steam could
penetrate electrical components and
cause a short circuit.
Never place hot pots or pans over
the display, as the underlying
electronics may be damaged.
IMPORTANT SAFETY INSTRUCTIONS
5

Injury prevention
Do not touch the cooktop or the
area surrounding it during or
immediately after use. The cooktop may
be hot even though it is dark in color.
Areas near it may become hot enough
to cause burns. Do not touch, or let
clothing or other flammable materials
touch the cooktop or areas near it until
they have cooled.
Wait until the residual heat indicators go
out.
CAUTION: Do not store toys or
items of interest to children in
cabinets above or behind the
appliance. Children climbing onto the
cooktop to reach these items may be
injured.
Children should not be left alone or
unattended near the appliance
when in use. They should never be
allowed to sit or stand on any part of
the appliance.
Protect your hands with insulated
gloves or potholders when using
the appliance. Use only dry, heat
resistant potholders. Moist or damp
potholders used on hot surfaces can
result in steam burns. Do not let the
potholder touch the hot heating
element. Do not use towels or other
bulky items near the appliance.
To prevent burns and breathing
difficulty, allow the cooktop to cool
before cleaning. Some cleaners may
produce toxic fumes if applied to a hot
surface.
Keep all pans out of reach of
children. Danger of burns
Pot and pan handles should be
turned inward and not extend over
the countertop to reduce the risk of
burns, ignition of flammable materials,
and spills.
Use the proper pan size.
Select cookware having flat
bottoms large enough to cover the
heating element. Using undersized
cookware will expose a portion of the
heating element to direct contact and
may result in ignition of clothing or
handles becoming hot. The proper size
pot or pan will also improve effeciency.
Before using glass, glass/ceramic,
ceramic, earthenware or other
glazed cookware on the cooktop, verify
that they can be used on a cooking
surface.
Do not heat unopened food
containers. Build-up pressure may
cause the container to burst and result
in injury.
At higher settings, be cautious of
splattering grease or boiling over
liquids, which may produce smoke.
IMPORTANT SAFETY INSTRUCTIONS
6

Before removing pots and pans, be
sure to turn off the burners.
Do not store items on the
appliance when not in use. Items
could melt or catch fire from residual
heat or if the cooktop is turned on
inadvertently.
Never cover the cooktop with a
cloth. A fire could result.
Never leave the cooktop
unattended when cooking with oil
or fat. Overheated fat could ignite.
Always heat oil slowly, monitoring it as it
heats.
Do not use water on grease fires.
Smother any fire or flame, or use a
dry chemical or foam-type extinguisher.
When frying food, make sure that
the food is as dry as possible
before placing it in the oil. Moisture can
cause hot oil to splatter and boil over.
Do not flambé under an exhaust
hood. Flames could be drawn up
into the hood by the suction or the
grease filters may ignite.
Do not let cooking grease or other
flammable materials accumulate
on the appliance.
Be aware of loose fitting or hanging
garments when operating the
cooktop, they may present a fire
hazard.
Flammable materials should not be
stored on or near your appliance.
If there is a drawer directly
underneath the appliance without
any wooden base in between, ensure
that no aerosols, combustible liquids or
other easily flammable materials are
kept in it. If cutlery inserts are to be
placed in the drawer, they must be
made of heat-resistant material.

Overheating protection
Each burner is equipped with a
temperature limiter. This limiter turns off
the heating elements in the burner
before the ceramic surface becomes
too hot. Once the ceramic surface has
cooled to a safe temperature, the
heating elements will automatically turn
back on.
The overheating protection can be
activated by:
–turning on a burner without putting a
pan on it.
– heating an empty pan.
– an uneven pan not sitting evenly on
the burner.
– the pan not conducting heat
properly.
If the heating elements cycle on and
off, even at the highest setting, the
overheating protection has been
activated.
Use
16

The cooking surface
Your ceramic cooktop is made of an
extremely hard and durable material.
The surface is scratch resistant, not
scratch proof. Avoid using cookware
with ridged bottoms. Ridged pots with
dirty or chipped enamel bottoms may
scratch the cooktop if they are pulled
across the ceramic surface.
Make sure the cooktop and pot bottoms
are clean before cooking. Certain
items, particularly sugar grains or
crystallized liquids such as molasses or
syrups are actually harder than ceramic
and can scratch the surface if they are
not cleaned off immediately. Small or
light scratches will not affect the safety
or performance of the cooktop however.
The burner rings are fused into the
ceramic glass and are resistant to wear
if properly maintained. Do not use
abrasive cleaners or pads, as they may
eventually wear off the rings.
Pots an pans
Special cookware is not required, but
as is true with all types of cooking
appliances, the better the cookware,
the better the performance.
Following these tips will allow you to
make the most of your ceramic
cooktop.
– For the most even and energy
efficient cooking, the diameter of the
pots should match the diameter of
the burners as closely as possible.
– Use cookware with thick, flat, smooth
bottoms. Slightly concave bottoms
will also work adequately. Pans with
convex bottoms will not cook well.
Selecting cookware
17

–Using a lid while cooking will
minimize the loss of heat and
decrease the cooking time.
–Copper bottom and aluminum pans
may leave a residue on the cooktop
in the form of metallic lines. This is
normal. These lines can be removed
using a non-abrasive ceramic
cooktop cleaner or a sheilded
scraper blade.
Be sure to clean the cooktop after
each use. Each time the residue is
allowed to melt it becomes harder to
remove and may mar the
appearance of the cooktop.
Let the cooktop cool before
cleaning.
–Cast iron, glass or stoneware should
not be used because they have poor
heat transfer and may scratch the
surface.
Selecting cookware
18

When cleaning the cooktop, make sure
the cooktop is "Off", and be careful not
to accidentally turn it "On".
Under no circumstances should a
steam cleaner be used to clean this
appliance. Pressurized steam could
cause permanent damage to the
surface and to components for which
the manufacturer cannot accept
responsibility.
Do not use any sharp pointed objects
which could damage the seal between
the ceramic surface, the surrounding
frame and the countertop.
Never use scouring agents, pads,
abrasive cleaning agents or strong
cleaners, e.g. oven sprays, stain or
rust removers, as these could
damage the surface of the appliance.
The ceramic surface can be cleaned
using a cleaner for ceramic
surfaces. Follow the manufacturer’s
instructions on the packaging.
Make sure that no cleaner residue
remains on the ceramic surface by
carefully wiping the cooktop with a
damp cloth. Cleaner residues could
damage the cooktop when heated.
After cleaning, thoroughly dry the
ceramic surface with a soft cloth to
prevent a build up of limescale
deposits.
The ceramic surface should be cleaned
regularly with a cleaner for ceramic
surfaces. Follow the ceramic cleaner
manufacturer’s instructions. If you have
difficulty locating a suitable product
contact Miele’s Technical Service
Department.
Before cleaning allow the cooktop to
cool. Wipe spills off using a damp
sponge. Stubborn spills are best
removed with a shielded scraper blade.
To remove any limescale deposits or
metallic residue apply ceramic cleanser
using a soft cloth or use a sheilded
scraper blade if necessary.
A cleaner with a special additive to
prevent water marks and smears on the
ceramic surface may be used.
After cleaning, wipe the ceramic
surface with a damp cloth to remove
any residue. Cleaner residues could
damage the cooktop or create toxic
fumes when heated. Finally, dry the
cooktop with a clean soft cloth.
Any melted solids (e.g. sugar, plastic,
syrup, aluminium foil, etc.) should be
removed as quickly as possible and
while the burner is still warm. If they are
allowed to harden, the cooktop may
become pitted. Scrape the melted item
off the cooktop using a sheilded
scraper blade. Once the cooktop has
cooled, remove any remaining residue
using a ceramic cooktop cleaner.
Cooktop care
19

All repairs should be performed by a
trained technician in strict
accordance with national and local
codes. Any repairs or maintenance
performed by unqualified personnel
could be dangerous.
What if ...
... the cooktop or burners cannot be
turne on?
Check whether the electrical circuit has
blown a fuse or "tripped" the circuit
breaker.
If this is not the case, disconnect the
appliance from the electricity supply for
1 minute by "tripping" the circuit
breaker, or withdrawing the fuse.
Reconnect the appliance to the
electrical supply and if the cooktop still
does not heat up, contact a qualified
electrician or Miele’s Technical Service
Department.
... the heating cycles on an off at the
highest setting on one of the
burners?
The overheating protection is activated
(see "Overheating protection").
