They contain important notes on
safety, on the operation and care of
the appliance. This way you will
avoid the risk of accidents and dam-
age to the appliance.
Do not let children access the ap-
pliance or its controls. Supervise its
use by the elderly or infirm.
Keep these instructions in a safe
place and pass them on to any fu-
ture user.
Correct usage
The appliance is intended for do-
mestic use to cook food. Any other
usage is at the owner’s risk and could
be dangerous. The manufacturer can-
not be held responsible for damage
caused by improper use of the ap-
pliance.
Technical safety
Before connecting the appliance
to the mains supply make sure that
the voltage and frequency correspond
to the rating on the data plate. Consult
a competent person if in doubt.
The electrical safety of this ap-
pliance can only be guaranteed
when continuity is complete between
the appliance and an effective earthing
system, which complies with local and
national regulations. It is most import-
ant that this basic safety requirement is
tested by a qualified electrician. The
manufacturer cannot be held respon-
sible for the consequences of an inade-
quate earthing system.
This appliance must only be oper-
ated as a built-in appliance. This is
necessary to ensure that all electrical
components are shielded.
Installation work and repairs may
only be carried out by suitably
qualified and competent persons to en-
sure safety. Repairs and other work by
unqualified persons could be dan-
gerous.
The appliance is only completely
isolated from the electricity supply
when:
– it is switched off at the wall socket
– or the mains fuse is withdrawn
– or the screw-out fuse is removed (in
countries where this is applicable)
Do not connect the appliance to
the mains electricity supply by an
extension lead.
Extension leads do not guarantee the
required safety of the appliance.

Warning and safety instructions
Use
Caution, danger of burning!
High temperatures are produced by
the hob cooking areas.
Great care should be taken to ensure
that small children do not touch the ap-
pliance when it is being used. The hob
can become quite hot. Turn pan
handles away from the edge to prevent
children from pulling pans over.
When switched on the cooking
areas heat up. A residual heat indi-
cator shows whether a cooking zone is
hot.
Apart from pans with contents do
not place any metallic object on
the hob. It could heat up. There is a
danger of burning.
In the event of any breakages or
cracks occurring in the ceramic
hob it must be switched off immediate-
ly and disconnected from the electricity
supply.
Contact the Service Department.
Do not use the hob until the damaged
ceramic plate has been replaced.
Continued use would be dangerous as
liquids etc. boiling over could pene-
trate to the electrical components
through any crack.
Do not use the hob as a resting
place for any other objects. This
could lead to a danger of the article
catching fire or melting, if there is any
residual heat.
Do not drop anything on the ce-
ramic hob.
Even a light object such as an egg
cup, could cause damage in certain cir-
cumstances.
Do not allow either solid or liquid
sugar or pieces of plastic or alu-
mium foil to get on to the cooking
zones when they are hot. If this should
occur, turn to a lower setting but do not
switch off. Immediately scrape off all
the sugar, plastic or aluminium remains
from the hob with a shielded razor
blade scraper, taking 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 crack-
ing.
Do not use any pots or pans on the
ceramic hob with bases with pro-
nounced edges or ridges.
These could scratch or scour the hob
surface permanently.
Do not push enamelled pots or
pans such as chip pans across the
ceramic hob as this can cause scrat-
ches to occur.

Warning and safety instructions
General notes
Under no circumstances use a
steam cleaner to clean this ap-
pliance. Pressurised steam could give
rise to a short circuit, or cause perma-
nent damage to the surface and to
components, for which the manufac-
turer of the oven cannot accept any
responsibility.
Do not leave the appliance unat-
tended when cooking with oils and
fats as these can be a fire hazard if
allowed to overheat.
Do not use plastic or aluminium foil
containers. These melt at high tem-
peratures. Additionally they could dam-
age a ceramic hob as they melt.
Do not use the ceramic hob to
heat up the room. Due to the high
temperatures radiated, objects left near
the hob could catch fire.
When using kitchen appliances
connected to sockets near the ce-
ramic hob, ensure that the cable can-
not come in contact with the hot cook-
ing zones, which could melt the cable
insulation and be dangerous.
Always ensure that food is suffi-
ciently cooked or reheated. Many
factors will affect the overall cooking
time, including the size and amount of
food, its temperature, changes to
recipe and the shape and size of cook-
ing container. Some foods may contain
micro organisms which are only de-
stroyed by thorough cooking, therefore
when cooking or reheating foods, e.g.
poultry, it is particularly important that
food is fully cooked through. If in doubt
select a longer cooking or reheating
time.
It is important that the heat is
allowed to spread evenly throug-
hout the food being cooked.
This can be achieved by stirring and/or
turning the food, and by observing a
sufficiently long standing time, which
should be added to the time needed
for cooking, reheating or defrosting.
In countries which may be subject
to infestation by cockroaches or
other vermin, pay particular attention to
keeping the appliance and its surround-
ings in a clean condition at all times.
Any damage which might be caused
by cockroaches or other vermin will not
be covered by the appliance guaran-
tee.

Warning and safety instructions
Use of accessories
After using the scraper ensure the
blade is shielded before putting it
away.
Keep these instructions in a safe
place and pass them on to any
future user.
Disposal of your old machine
Before discarding an old machine
switch off and disconnect it from
the power supply. Cut off and render
any plug useless.
Cut off the cable directly behind the
machine to prevent misuse.
The manufacturer cannot be held
liable for damage caused by non-
compliance with safety instructions.

Safety feature
Lock for hob
The hob lock can be used to prevent
the cooking zones from being switched
on inadvertently, when used either with
the oven, or oven with built-in hob con-
trols. It does not apply to the warming
zone.
The operating instructions for the oven
with built-in hob controls or the control
unit describe how to set the hob lock.
9

Hob controls
The cooking zones are controlled by
heat regulators.
Only turn the cooking zone control
as far as it will go in a clockwise
direction and back again. Turning
the control any other way could
damage it.
The display for the cooking zone lights
up when the cooking zone is switched
on. The colour of the display will
deepen from a light shade for a low set-
ting to a red for the highest setting
The cooking zone controls are fitted
with an "Auto heat-up" feature. This is
activated when the cooking zones are
switched on. After reaching an initial
high temperature the "Auto heat-up" the
automatically switches to the continua-
tion setting choosen, and the heat is lo-
wered accordingly, without the need for
manual intervention.
The length of the "Auto heat-up" time
depends on the setting selected.
Different heat-up times have been pro-
grammed for settings 1 – 7 (for boiling)
and 8 – 12 (for frying).
The "Auto heat-up" period increases in
step with settings 1 – 7; from 8 – 12
however the times are shorter.
If the setting within range 1 – 7 is al-
tered during the "Auto heat-up" period
the period will lengthen accordingly.
If the pan is removed from the cook-
ing zone when "pan recognition"
has been activated, the cooking
zone will switch itself off, but the
"Auto heat-up" period will continue
to count down.
If you wish you can turn "Auto heat-
up" off:
Turn the cooking zone control to a
setting.
The setting must be higher than the
one required.
After 10 seconds turn the control to
the setting required.
The "Auto heat-up" is now inactivated.
For cookers and control units with a
clock timer
When the two front zones are being
used for cooking they can be switched
on or off automatically independently of
each other.

Description of the hob
Cooking zones - diameters
The cooking zones are clearly marked
on the hob surface.
Only the particular zone which has
been switched on will beheated. The
rest of the hob surface remains rela-
tively cool.
Residual heat indicator
There is an indicator light for each
cooking zone in the hob display field.
When a cooking zone is switched on its
indicator lights up.
This also serves as a residual heat in-
dicator, which stays on after the cook-
ing zone has been switched off, and
only goes out when this area of the ce-
ramic surface has reached a tempera-
ture safe to touch.
Pan recognition
Each cooking zone has a "pan recogni-
tion" feature. With this the zone only
starts heating up once a pan has been
placed on it.
"Pan recognition" reacts when a pan
of a suitable metal is used.
It also reacts when any object of a
suitable metal is placed on it, so it
is very important to switch the zone
off immediately after use for cook-
ing.
When the pan is removed, the flow of
energy is interrupted. The indicator
light in the hob display field for that
zone flashes.
When the pan is placed back on the
zone the zone switches on again and
the light stays on constantly.
If you are using a pan made from
non-metallic material, e.g. glass, ce-
ramic, you can turn off the "pan rec-
ognition" feature as follows:
Turn the control anti-clockwise be-
yond the figure "0" until the control
light comes on.
Then turn the zone control clockwise
to the setting required.
To reactivate the "pan recognition" fea-
ture again turn the zone control to "0".
12

Description of the hob
Extended cooking zones •
Use the corresponding cooking zone
control to switch on the extended zone.
There is an indicator light in the hob dis-
play field for each extended cooking
zone. This lights up when the cooking
zone extension is switched on.
Turn the control in a clockwise direc-
tion until a resistance is felt. Other-
wise it can be damaged.
Turn the control clockwise beyond
setting 12 to the symbol "•".
Then turn to the setting required.
Turning the control back to "0"
– switches off the cooking zone,
– switches off the cooking zone exten-
sion.
13

Hobs - use
Choice of suitable pans
Attention to correct choice and use of
pans
– will help you obtain the best cooking
result most economically,
– and generally avoid food boiling
over and sticking.
Pan bases
For maximum economy of electricity
when cooking or frying, only use pans
with a flat or very slightly concave
base. When hot the pan will rest evenly
on the hob. Modern saucepans for elec-
tric cookers are the most suitable and
efficient for use on ceramic cooking
zones.
Size of pan
The diameter of the saucepan or frying
pan should be very slightly larger than
that of the hotplate/cooking area.
Pan lids
Cooking with the lid on the pan retains
the heat.
14

Hobs - use
Notes on the use on hobs
Take care before starting to cook
that there is no grit or sand on the
surface of the hob.
This would scratch the surface, espe-
cially if a pan was pushed across.
Do not use any pots or pans where
the base has ridges or a pro-
nounced edge.
These could also cause scratches.
Do not push roasting tins or baking
trays etc across the ceramic sur-
face. Scratches could occur.
Aluminium or stainless steel pans
with aluminium bases can leave
marks with a metallic sheen on the
ceramic surface. Clean these away
at the earliest opportunity, (see Sec-
tion on Cleaning and Care).
Never leave boiled-over sugar or sy-
rups, plastic items or aluminium foil
on the hob. If this does happen,
turn the hob to a lower setting, but
on no account switch it off. Use a
shielded scraper blade to scrape
off the sugar, plastic or foil residue
thoroughly.
If these residues are allowed to cool be-
fore the hob surface has been cleaned,
the ceramic surface will be susceptible
to pitting or even cracking.
15

Cleaning and care
Ceramic hob surface
In general you can use the same clean-
ing agents for the ceramic hob surface
as you would for ordinary glass sur-
faces.
Never use scouring agents or pads,
or strong cleaners such as oven
sprays or stain removers, as these
could harm the surface.
Clean after each use
Any minor spills which have not
dried on can be wiped off with a
damp cloth or sponge. If washing up
liquid or a similar cleaner is used, light
blue staining might occur.
These stains can be removed with a
proprietary ceramic hob cleaning
agent, although it may take several ap-
plications.
For stubborn spillages use a shielded
razor blade scraper.
Then wipe with a damp cloth or
sponge.
Removing marks
Light marks with a metallic sheen
(aluminium desposits) on the hob sur-
face can be removed once the hob has
cooled down by using a suitable pro-
prietary cleaner.
Lime deposits (caused for example by
water boiling over, or damp pan bases)
can be removed with vinegar or a pro-
prietary hob cleaner.
16

Cleaning and care
Removal of sugar, or syrups, plastic
or aluminium foil
Do not let the hob cool down.
Scrape the sugar or other residue
thoroughly from the hob with a
shielded razor blade scraper.
When the hob is cool, switch off and
clean with a proprietary cleaner.
Suitable cleaners
There are proprietary cleaners on the
market for cleaning ceramic hobs. Fol-
low the manufacturer’s instructions.
Do not apply to the hob when still
hot.
After applying the cleaner let it dry and
then rub it off using paper kitchen to-
wels.
Remove every trace of cleaner from
the hob with a damp cloth. It could
have an adverse effect on the hob
when heated up.
Some cleaners incorporate a silicone
ingredient which acts as a protective
film on the hob. It makes the hob sur-
face smoother and prevents water and
soiling adhering to the surface.
However, cooking at high temperatures
reduces the effect and the cleaner
needs to be reapplied for renewed ef-
fect.
By always cleaning the ceramic sur-
face with one of these special cleaners
you will help to avoid the damage
caused by sugar and syrups and alumi-
nium foil deposits.
17

Correcting minor faults
Installation, maintenance and re-
pairs to the electrical components
of this appliance should only be car-
ried out by a fully competent per-
son.
Unauthorised repairs can be dan-
gerous.
Some minor problems however can be
dealt with as follows:
What to do if . . .
. . . A slight smell is given off briefly
when the hob heats up for the first
time?
This is not a fault but is caused by the
moisture in the insulation dissipating.
. . . The hob cooking zones do not
warm up after being switched on
Check to see whether the control dis-
play is illuminated.
If not, check whether:
the hob lock is activated.
the house mains fuse has blown.
Contact a qualified electrician or the
Miele Service department.
. . . A cooking zone switches itself off
during use?
This is not a fault.
If the cooking zone is used for an un-
usually long period of time the safety
switch is activated.
The length of time, between approx
1 – 10 hours, depends on the setting
which has been programmed. The
higher the setting the shorter the time
before the automatic safety switch is
activated.
To use the cooking zone again:
Turn the cooking zone control first of
all to another setting and then back
to the setting originally used.
If the setting is altered during the cook-
ing process the time will be calculated
according to the most recently selected
setting.
18

Correcting minor faults
. . . The contents in the pan are not
properly cooked or have not started
to cook?
Check whether:
You are using a pan with a heat re-
taining bottom surface.
The heat from the bottem of the pan will
transfer slowly to the food.
You are using too large a pan.
In both of the above cases, choose a
higher heat-up level or bring to the boil
at setting 12 and then turn down.
. . . The indicator light in the hob dis-
play is flashing?
The "pan recognition" feature is not
operating.
Check whether:
You are using a non-metallic pan.
If so switch off the "pan recognition".
There was a delay in placing the pan
on the cooking zone after it was
switched on. In this case it is necess-
ary to turn the cooking zone control
back to "0" before the hob can be
brought into use again.
