Packaging material / Disposal of old machine
2
Packaging material
The packaging material used protects
the machine during transportation.
Please retain the original box and poly-
styrene pieces so that you can pack the
machine securely, should you need to
transport it in the future.
The original packaging should also be
kept in case the machine ever needs to
be returned to Miele for servicing.
Disposing of your old appli-
ance
Electrical and electronic appliances of-
ten contain valuable materials. They
also contain specific materials, com-
pounds and components, which were
essential for their correct function and
safety. These could be hazardous to hu-
man health and to the environment if
disposed of with your domestic waste
or if handled incorrectly. Please do not,
therefore, dispose of your old appliance
with your household waste.
Please dispose of it at your local com-
munity waste collection / recycling
centre for electrical and electronic ap-
pliances, or contact your dealer or
Miele for advice. You are also respons-
ible (by law, depending on country) for
deleting any personal data that may be
stored on the appliance being disposed
of. Please ensure that your old appli-
ance poses no risk to children while be-
ing stored prior to disposal.

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.
 To avoid the risk of damage to the machine, make sure the con-
nection data (voltage and frequency) on the data plate corresponds
to the household supply, before connecting the machine to the
mains supply. Consult a qualified electrician if in any doubt.
 The electrical safety of this coffee machine can only be guaran-
teed when correctly earthed. It is essential that this standard safety
requirement is met. If in any doubt please have the electrical installa-
tion tested 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 are a fire hazard
and do not guarantee the required safety of the appliance.
 The coffee machine must not be used in a non-stationary location
(e.g. on a ship).
 Unplug the machine from the power supply immediately if you no-
tice 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 damage the machine.
 Only use the coffee machine in rooms where the ambient temper-
ature 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.

Warning and Safety instructions
10
 If the coffee machine is positioned 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 ma-
chine 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.
 While the machine is under guarantee, repairs should only be un-
dertaken by a Miele authorised service technician. Otherwise the
guarantee is invalidated.
 Faulty components must only be replaced by genuine Miele Ori-
ginal spare parts. The manufacturer can only guarantee the safety of
the machine when Miele replacement parts are used.
 The coffee machine must be disconnected from the electricity
supply during repair work.
 Never open the outer casing of the machine. Tampering with elec-
trical connections or components and mechanical parts is highly
dangerous to the user and can cause operational faults or electric
shock.
 Only use genuine original Miele accessories with this machine.
Using spare parts or accessories from other manufacturers will inval-
idate the guarantee, and Miele cannot accept liability.

Warning and Safety instructions
11
Correct use
The 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 li-
quids and steam are being dispensed.
– Do not touch hot components.
– Hot liquid or steam could spatter from the spouts. 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 to look
at it.
 Please note the following regarding water:
– Only use cold, fresh tap water to fill the water container. 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 limes-
cale deposits to build up in your machine and damage it.
– Do not use water from a reverse osmosis unit in this machine.
This would damage it.
 Only fill the bean container with roasted espresso/coffee beans.
Do not fill the bean container with coffee beans which have been
treated with additives or with ground coffee.
 Do not fill the bean container with any type of liquid.

Warning and Safety instructions
12
 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 including sugary liquids. Sugar will dam-
age the coffee machine.
 Only add ground coffee or the Miele cleaning tablets for degreas-
ing the brew unit to the ground coffee chute.
 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 dairy milk make sure that it has been pasteurised.
 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 ma-
chine. The coffee machine could catch fire with the risk of the fire
spreading.
 The machine must not be used for cleaning objects.

Warning and Safety instructions
13
Cleaning and care
 The coffee machine must be disconnected from the electricity
supply before cleaning or maintenance.
 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 inad-
equate cleaning.
 Do not use a steam cleaner to clean this machine. Steam could
reach electrical components and cause a short circuit.
 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
agent or the use of descaling agent which is not of the appropriate
concentration.
 Degrease the brew unit regularly with Miele cleaning tablets. De-
pending 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 rub-
bish or on the compost heap. Do not empty them down the sink, as
they could block it.

Warning and Safety instructions
14
For machines with stainless steel surfaces:
 Do not use sticky notes, transparent adhesive tape, masking tape
or other types of adhesive on stainless steel surfaces. These dam-
age the surface, causing it to lose its dirt repellent protective coating.
 The finish on stainless steel surfaces is susceptible to scratching.
Even magnets can cause scratching.

velop fully until several coffees have
been made.

Using for the first time
19
Switch the coffee machine off with
the On/Off sensor. Do not switch
it off by withdrawing the plug. If you
disconnect it from the mains at this
early stage you will have to set it up
for use again.
A larger amount of beans will be
ground for the first few coffees. This
can lead to residues of ground coffee
settling on the lid in the drip tray.
The full aroma of the coffee and its
typical crema will not develop fully un-
til a few coffees have been made.
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 ma-
chine will need to be descaled.
The coffee machine measures the
amount of water used and steam made.
Depending on the level of water hard-
ness set, more or fewer drinks can be
dispensed before the machine needs to
be descaled.
Programme the coffee machine to the
water hardness level of your area so
that it functions correctly and does not
get damaged. A prompt to descale the
machine will then appear in the display
at the correct time.
Contact your local water supplier to find
out your local water hardness range if
necessary.
The machine is programmed ex-works
to hardness level 3.
The machine has four programmable
levels:
