children well away and do not let them
play with it or use the controls. They will
not understand the potential dangers
posed by it. They should be supervised
whenever you are working in the
kitchen.
Old appliances must be
disconnected from the power
supply, the plug rendered useless and
the cable cut off directly behind the
appliance to ensure it presents no
danger to children while being stored
for disposal.
Older children may use the
appliance only when its operation
has been clearly explained to them,
and they are able to use it safely,
recognising the dangers of misuse.
Supervise its use by the elderly or
infirm.

Do not use pots or pans on the
ceramic hob with bases with
pronounced edges or ridges. These
could scratch or scour the hob surface
permanently. Grains of salt and sand
can also scratch.
Unless the pan manufacturer
states that you can do so, do not
use pans with very thin bases on this
hob and never heat up empty pans as
they could get damaged. This could
also damage the appliance.
Do not allow either solid or liquid
sugar, or pieces of plastic or

cooking zones when they are hot. If this
should occur, switch off the hob and
carefully scrape off all the sugar, plastic
or aluminium remains from the hob
while it is still hot using a shielded
scraper blade. Take care not to burn
yourself. If these residues are allowed
to cool before the hob surface has
been cleaned, the ceramic surface will
be susceptible to pitting or even
cracking.
In countries where there are areas
which may be subject to infestation
by cockroaches or other vermin, pay
particular attention to keeping the
appliance and its surroundings in a
clean condition at all times. Any
damage which may be caused by
cockroaches or other vermin will not be
covered by the appliance guarantee.

bases are clean, dry and free of
grease.
11
Warning and Safety instructions
Protection from burning and
scalding
Do not cover the appliance, e.g.
with a cloth, kitchen foil, etc. This
could be a fire hazard if the appliance
is switched on by mistake.
The surface of the appliance is hot
when in use, and remains hot for
quite a while after being switched off.
There is a danger of burning until the
residual heat indicators go out.
Never leave the appliance
unattended when cooking with oil
or fat as these are fire hazards if
overheated. Very hot oil can catch fire
and could even set a cooker hood
above on fire. Always heat fat slowly,
watching as it heats.
For added protection it is advisable
to use heat-resistant pot holders or
gloves when using the appliance. Do
not let them get damp or wet, as this
causes heat to transfer through the
material more quickly with the risk of
scalding or burning yourself.
If, despite this, oil or fat does catch
fire, do not attempt to put out the
flames with water. Use a suitable fire
blanket, saucepan lid, damp towel or
similar to smother the flames.
Do not heat up unopened tins of
food on the hob as pressure will
build up in the tin and it can explode.
This could result in injury and scalding
or damage.
Do not flambé under a cooker
hood. The flames could set the
cooker hood on fire.
Do not use the hob as a resting
place for anything else. The article
could melt or catch fire if residual heat
is still present or if the appliance is
switched on by mistake.

Before using for the first time
General notes
Cleaning and heating up for
the first time
A data plate for your appliance is
supplied with this documentation. It
should be stuck into the space
provided at the end of the instruction
book.
Before using for the first time, clean the
appliance with a damp cloth only and
then wipe dry.
Do not use washing up liquid on the
ceramic surface as it can leave a
blue sheen which may be difficult to
remove.
Keep these instructions in a safe place
for reference and pass them on to any
future user.
Metal components have a protective
coating which may give off a slight
smell when the hob is heated up for the
first time. The smell and any vapours
will dissipate after a short time and do
not indicate a faulty connection or
appliance.
15
Use
Sensor switches
Switching on
This hob is equipped with electronic
sensor switches which react to finger
contact.
The hob must be switched on before
any of the zones can be used.
To operate a cooking zone, touch the
relevant sensor switch. Each time you
touch a sensor switch an audible tone
sounds.
To switch the hob on:
^ Touch the ON / OFF sensor s.
0 appears in each of the zone displays.
00 appears in the timer displays. If no
further entry is made, the hob will
switch itself off after about 30 seconds
for safety reasons.
Make sure that you only touch the
sensor you require except when
switching off a cooking zone or the
timer, and that you touch the centre
of the sensor.
To switch a cooking zone on:
^ Select a power setting between 1 and
12 by touching the - or + sensor.
Take care to keep the control area
clean. Do not place anything on the

Suitable pans
Energy saving tips
– For optimum energy consumption
during cooking, only pans with flat or
very slightly concave bases should
be used. When the pan is hot, the
base should rest evenly on the hob.
Uneven bases will lengthen cooking
time. Check for suitability when
purchasing new pans.
– Use a pan lid whenever possible to
minimise heat loss.

hot
– Check that the diameter of the pan
base is wide enough for the cooking
zone so that heat is not lost
unnecessarily. Please note that the

on the packaging and apply using a
soft cloth or kitchen paper towel.
Never use cleaners containing sand,
soda, alkalis, acids or chlorides,
oven sprays, dishwasher
detergents, nor steel wool, abrasive
cleaning agents, hard brushes,
scouring pads and cloths. You
should also avoid using sponges
etc. which have previously been
used with abrasive cleaning agents,
as this will damage the surface.
Finally, wipe the hob surface with a
damp cloth and then dry it with a clean
soft cloth. Ensure that every trace of
cleaner has been removed from the
surface. Any remaining trace could
have a corrosive effect on the hob
when it is next heated up.
Do not use washing up liquid to
clean the ceramic surface as it can
leave a blue sheen which may be
difficult to remove.
E-Cloth
Note that some cleaning agents contain
a protective additive designed to
prevent water marks and smears
adhering to the surface.
A microfibre "E-Cloth" is available from
the Miele UK Spare Parts Department
which is suitable for cleaning surfaces
such as stainless steel, glass, plastic
and chrome without the use of
chemicals.

Cleaning and care
Should any sugar, plastic or
aluminium foil spill or fall on to a hot
cooking zone while it is in use, first
switch off the appliance. Then, immedi-
ately, while they are still hot, scrape off
all remains of these materials using a
shielded scraper blade. Take care not
to burn yourself.
Allow the hob to cool down and then
clean with a suitable proprietary
ceramic cleaner.
