Disposal of the packing
material
The packaging is designed to protect
the appliance from damage during
transportation. The packaging materials
used are selected from materials which
are environmentally friendly for disposal
and should be recycled.
Recycling the packaging reduces the
use of raw materials in the
manufacturing process and also
reduces the amount of waste in landfill
sites.
Disposal of your old machine
Electrical and electronic machines
often contain valuable materials. They
also contain materials which, if handled
or disposed of incorrectly, could be
potentially hazardous to human health
and to the environment. They are,
however, essential for the correct
functioning of your machine. Please do
not therefore dispose of it with your
household waste.
Please dispose of it at your local
community waste collection/recycling
centre, or contact your Dealer for
advice. Ensure that it presents no
danger to children while being stored
for disposal.

unsupervised.
~Please supervise children in the vicinity of the coffee machine
and do not allow them to play with it.
Remember that coffee and espresso are not suitable drinks for

children could become entangled in packaging or pull it over their
head and suffocate.
Warning and Safety instructions
11

Technical safety
~A damaged coffee machine could be dangerous. Before building
in the machine, check it for any externally visible damage. Do not
use a damaged machine.
~Before connecting the machine to the mains supply, make sure
the connection data (voltage and frequency) on the data plate
corresponds to the household supply. Consult a qualified electrician
if in any doubt.
~The electrical safety of this machine can only be guaranteed if
correctly earthed. It is essential that this standard safety requirement
is met. If in any doubt, please have the electrical installation tested
by a qualified electrician.
~Do not connect the machine to the mains electrical supply by a
multi-socket adapter or an extension lead. These are a fire hazard
and do not guarantee the required safety of the machine.
~For safety reasons, this machine may only be used when it has
been built in.
~If the coffee machine is to be built in above another appliance,
there must be a full-width, closed shelf between them.
~The coffee machine must not be used in a non-stationary location
(e.g. on a ship).
~Only use the coffee machine in rooms where the ambient
temperature is between +10 °C and +38 °C.
Warning and Safety instructions
12

~Ensure that there is sufficient ventilation around the coffee
machine. Otherwise condensation can build up and damage the
machine and / or the housing unit.
~If the coffee machine is installed behind a kitchen furniture door,
it may only be used with the furniture door open. Do not close the
furniture door while the coffee machine is in use.
~Repairs may only be carried out by a Miele authorised service
technician. Repairs and other work by unqualified persons can
cause considerable danger to users. The manufacturer cannot be
held liable for unauthorised work.
~While the appliance is under guarantee, repairs should only be
undertaken by a Miele authorised service technician. Otherwise the
guarantee is invalidated.
~Miele can only guarantee the safety of the machine when original
Miele replacement parts are used. Faulty components must only be
replaced by genuine Miele original spare parts.
~The machine must be disconnected from the electrical supply
during installation or repair work.
~Do not 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.
Warning and Safety instructions
13

~Only use genuine original Miele accessories with this appliance.
Using spare parts or accessories from other manufacturers will
invalidate the guarantee, and Miele cannot accept liability.
Correct use
,Caution. The central spout and the steam valve present a
danger of burning and scalding.
The liquids and steam dispensed are very hot.
Please note:
– Keep well away from the area underneath the central spout and
steam valve when hot liquids and steam are being dispensed.
– Do not touch hot components.
– The spouts can spray hot liquid or steam.
– Water in the drip tray can be very hot. Take care when emptying
it.
,Danger of injury.
Do not touch the brew unit when the machine is connected to the
electrical supply.
Do not clean the inside of the capsule plate opening.
,Never look directly at the lighting or use optical instruments to
look at it.
~Clean the coffee machine and the cappuccinatore (milk frother)
thoroughly before using for the first time (See "Cleaning and care").
Warning and Safety instructions
14

~Please note the following regarding water:
–Only use cold, fresh tap water to fill the water container. Warm or
hot water or other liquids could damage the 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 a reverse osmosis unit in this machine. This
would damage it.
~Do not put anything other than Nespresso coffee capsules in the
capsule carousel. Other manufacturers' capsules etc. would
damage the machine.
~The coffee capsules must be intact before use. Do not use coffee
capsules which are damaged, broken or dented. These could
become jammed in the machine and damage it.
~Do not use milk with additives. Sugar additives will stick to the
milk pipework and damage the coffee machine and the
cappuccinatore.
~If using animal milk, use only pasteurised milk.
~Never place a drink with ignited alcohol under the central spout of
the coffee machine. The flames could ignite plastic components
and cause fire damage.
~Do not swing from or hang anything on the machine front when it
is open as this could damage the machine.
Warning and Safety instructions
15

~Please note the following with regard to cleaning the coffee
machine:
–Clean the coffee machine and the cappuccinatore daily (see
"Cleaning and care").
–Do not use a steam cleaner to clean the machine. Steam could
reach electrical components and cause a short circuit.
–Descale the coffee machine regularly using the appropriate
number of Miele descaling tablets for the water hardness level in
your area. Descale the machine more frequently in areas with very
hard water. The manufacturer cannot be held liable for damage
arising from insufficient descaling.
~Do not use the coffee machine or the cappuccinatore for cleaning
other objects.
For machines with a stainless steel front:
~Do not use sticky notes, transparent adhesive tape, masking tape
or other types of adhesive on stainless steel surfaces. These
damage 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.

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
quantity of water and steam used. The
number of drinks which can be
dispensed before the machine needs to
be descaled will depend on the water
hardness level set.
Set the water hardness level on the
coffee machine to the water hardness
level for the local area to ensure that
the machine functions correctly and is
not damaged. This will ensure that the
reminder to descale the machine will
appear in the display at the correct
time.
The machine has four programmable
levels:
Water hardness Local water
