8
Warning and Safety instructions
Technical safety
A damaged coffee machine is dangerous. Check it for any visible
damage before setting it up. Never attempt to use a damaged coffee
machine.
Before connecting the appliance to the mains supply, make sure
that the rating on the data plate corresponds to the voltage and
frequency of the household supply. This data must correspond in
order to avoid the risk of damage to the appliance. Consult a
qualified electrician if in any doubt.
The electrical safety of this appliance can only be guaranteed
when continuity is complete between it and an effective earthing
system. It is most important that this basic safety requirement is
present and tested regularly and, where there is any doubt, the
household wiring system should be inspected by a qualified
electrician.
Reliable and safe operation of the coffee machine can only be
guaranteed if it is connected to the mains electrical supply.
Do not connect the machine to the mains electricity supply by a
multi-socket adapter or an extension lead. These do not guarantee
the safety of the appliance (e.g. danger of overheating).
This appliance must not be installed and operated in mobile
installations (e.g. on a ship).
Unplug the machine from the power supply immediately if you
notice any damage or smell scorching, for example.
Ensure that the mains connection cable cannot be pinched or
damaged by any sharp edges.
The mains connection cable should not hang down. Someone
could trip over it with the risk of injury and the machine could be
damaged.
9
Warning and Safety instructions
Only use the coffee machine in rooms where the ambient
temperature is between +10°C and +38°C.
Danger of overheating! Ensure that there is sufficient ventilation
around the coffee machine. Do not cover it with tea towels etc.
whilst it is in use.
If the coffee machine is installed behind a kitchen furniture door, it
may only be used with the furniture door open. This will prevent the
formation of heat and humidity and subsequent damage to the
appliance and/or furniture unit. Do not close the furniture door while
the coffee machine is in use. Ensure the coffee machine has cooled
down completely before closing the furniture door.
Protect the coffee machine from water and water spray. Do not
immerse the machine in water.
Repairs and other work by unqualified persons to the machine
and the connection cable could be dangerous. The manufacturer
cannot be held liable for unauthorised work. Repairs may only be
carried out by a Miele authorised service technician.
The manufacturer's warranty will be invalidated if the appliance is
not repaired by a Miele approved service technician.
Faulty components must only be replaced by genuine Miele
original spare parts. The manufacturer can only guarantee the safety
of the appliance when Miele replacement parts are used.
10
Warning and Safety instructions
Before any repair work is carried out, the appliance must be
completely disconnected from the electricity supply. The appliance is
only completely isolated from the electricity supply when:
– it is switched off at the wall socket and the plug is withdrawn from
the socket. Do not pull the mains connection cable but the mains
plug to disconnect your appliance from the mains electricity
supply.
– the mains circuit breaker is switched off.
Never open the outer casing of the machine. Tampering with
electrical connections or components and mechanical parts is highly
dangerous to the user and can cause operational faults or electric
shock.
Use only Miele original spare parts. If spare parts or accessories
from other manufacturers are used, the warranty will be invalidated,
and Miele cannot accept liability.
11
Warning and Safety instructions
Correct use
The dispensing spouts present a danger of burning or
scalding.
The liquids and steam dispensed are very hot.
Please note:
– Keep well away from the area underneath the spouts when hot
liquids and steam are being dispensed.
– Heating surfaces have residual heat after use. Do not touch hot
components.
– Hot liquid or steam could spatter from the nozzles. Ensure that
the central spout is clean and fitted correctly.
– Water in the drip tray can also be very hot. Take care when
emptying it.
CM6350:Risk of injury to the eyes!
Never look directly at the lighting or use optical instruments
(magnifying glass or similar) to look at it.
Please note the following regarding water:
– Fill the water container only with fresh, cold tap water. Hot or
warm water or other liquids could damage the coffee machine.
– Change the water every day to prevent a build-up of bacteria.
– Do not use mineral water. Mineral water will cause serious
limescale deposits to build up in your machine and damage it.
– Do not use water from reverse osmosis units. The machine could
be damaged.
Only fill the bean container with roasted espresso or coffee beans.
Do not fill the bean container with coffee beans which have been
treated, e.g flavoured or caramelised, or with ground coffee.
Do not fill the bean container with any type of liquid.
12
Warning and Safety instructions
Do not use green (unroasted) coffee beans or mixtures of coffee
beans which contain green coffee beans. Green coffee beans are
very hard and still contain a certain amount of residual moisture.
These can damage the coffee machine grinder as soon as grinding
begins.
Do not use coffee beans which have been treated with caramel,
sugar or other substances. Sugar will damage the coffee machine.
Do not use any caramelised ready ground coffee. The sugar in the
coffee will stick to and block the brew unit of the coffee machine.
The cleaning tablets for degreasing the brew unit will not remove this
type of deposit.
Only use milk without additives. Additives in milk usually contain
sugar and this will stick to the milk pipework.
If using cow's milk, only use pasteurised milk to prevent a build-
up of bacteria in the appliance.
Do not place any alcohol mixtures which are alight underneath the
central spout. The flames could ignite plastic components and cause
them to melt.
Do not use naked flames, e.g. a candle, on or near the coffee
machine. The coffee machine could catch fire with the risk of the fire
spreading.
The machine must not be used for cleaning objects.
13
Warning and Safety instructions
Cleaning and care
Disconnect the coffee machine from the power supply before
cleaning.
Clean the coffee machine and the milk flask (supplied as standard,
depending on model) daily, particularly before using for the first time
(see "Cleaning and care").
All parts of the milk system need to be cleaned thoroughly and
regularly. Milk contains bacteria which proliferate rapidly with
inadequate cleaning.
Do not clean the machine with a steam cleaner or immerse it in
water as this will damage the machine. Steam or water could reach
the electrical components and cause a short circuit.
Avoid spillage on appliance connectors.
Descale the coffee machine regularly depending on the water
hardness level in your area. Descale the machine more frequently in
areas with very hard water. Miele cannot be held liable for damage
arising from insufficient descaling, the use of incorrect descaling
agents or the use of a descaling agent which is not of the
appropriate concentration.
Degrease the brew unit regularly with Miele cleaning tablets.
Depending on the natural oil content of the coffee used, the brew
unit can become blocked quite quickly.
Used coffee grounds should be disposed of with the organic
rubbish or on the compost heap. Do not empty them down the sink,
as they could block it.
14
Warning and Safety instructions
The following applies to appliances with stainless steel surfaces:
Do not adhere stickers, adhesive tape or any other adhesive
materials to stainless steel surfaces. The coating on the stainless
steel surfaces will become damaged and lose its protective
properties against soiling.
Stainless steel scratches very easily and even magnets can cause
damage to the surface.

powder from the coffee grounds may
adhere to the cover of the drip tray.
Water hardness
The water hardness level indicates how
much calcium is dissolved in the water.
The higher the calcium content, the
harder the water, and the harder the
water, the more often the coffee
machine will need to be descaled.
The coffee machine measures the
amount of water and steam used.
Depending on the level of water
hardness set, more or fewer drinks can
be dispensed before the appliance
needs to be descaled.

surface that the water container sits
on is dirty. If the water container is
not sitting correctly, the drain valve
will not be sealed. Clean the surface
if necessary.
23
Filling the coffee bean container
Fill the coffee bean container with
roasted coffee or espresso beans if you
want to use freshly ground coffee beans
for each cup of espresso or coffee.
Alternatively, you can make coffee or
espresso with ready ground coffee (see
"Making coffee or espresso using ready
ground coffee").
Important! Risk of damage to the
grinder.
Only put roasted coffee or espresso
beans in the container. Anything
else, including ground coffee, will
damage the grinder.
Do not fill the bean container with
any type of liquid.
Important! Sugar damages the coffee
machine.
Do not use coffee beans that have
been treated with sugar, caramel, or
other substances and do not put
liquids containing sugar in the coffee
bean container.
Do not use green (unroasted) coffee
beans or mixtures of coffee beans
which contain green coffee beans.
Green coffee beans are very hard
and still contain a certain amount of
residual moisture. These can
damage the coffee machine grinder
as soon as grinding begins.
Useful tip: You can use a nut or seed
grinder to grind green coffee beans.
These types of grinder generally have a
rotating stainless steel blade. You can
then add the ground green coffee
portion by portion to the ground coffee
chute and make the desired coffee
drink (see "Making drinks with ready
ground coffee").
Take the lid off the coffee bean
container.
Fill the container with roasted coffee
beans.
Refit the lid.

Cup heating
(CM6350)
Cups should always be pre-heated to
allow the flavour of the coffee to
develop and be retained.
The smaller the volume of the coffee/
espresso and the thicker the cup, the
more important it is to pre-heat the cup.
You can pre-heat cups or glasses on
the cup heating surface on the top of
the coffee machine.
The cup heating function must first be
switched on.
The cup heating surface will be heated
continually until the coffee machine is
turned off.
Switching cup heating on or off
Touch .
Select Cup heating and touch OK.
Select the required option and touch
OK.
Pre-heating cups

26
Adjusting the central spout to the correct cup height
You can adjust the central spout to suit
the height of the cup you are using so
that the coffee or espresso will not cool
down as quickly and the crema will
have a better consistency.
Pull the central spout down until it is
at the same level as the rim of the
cup.
Alternatively, push the central spout
up until there is enough room to fit a
larger cup or mug underneath.
