Disposal of the packing
material
The packaging material protects the
appliance from transport damage. 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. Ensure that any plastic
wrappings, bags etc. are disposed of
safely and kept out of the reach of
babies and young children. Danger of
suffocation!
Disposal of the Miele descaling
cartridge
Dispose of the used Miele descaling
cartridge in your household waste.
Disposing of your old
appliance
Electrical and electronic appliances
often contain valuable materials. They
also contain specific materials,
compounds and components, which
were essential for their correct function
and safety. These could be hazardous
to human 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
community waste collection / recycling
centre for electrical and electronic
appliances. You are also responsible for
deleting any personal data that may be
stored on the appliance prior to
disposal. Please ensure that your old
appliance poses no risk to children
while being stored prior to disposal.

for their safety, and are able to recognise the dangers of misuse.

Warning and Safety instructions
9
Safety with children
Danger of burning and scalding on the dispensing spouts.
Children's skin is far more sensitive to high temperatures than that
of adults.
Ensure children do not touch hot surfaces of the coffee machine or
place parts of their body under the dispensing spouts.
 Install the coffee machine out of reach of children.
 Young children must be kept away from the machine and the
mains connection cable and plug/socket.
 Older children may only use the coffee machine unsupervised if
they have been shown how to use it safely and recognise and
understand the consequences of incorrect operation.
 Children should be supervised when they are near the coffee
machine. Do not allow them to play with it or to use the controls.
 Young children must not be allowed to clean the coffee machine.
Cleaning may only be carried out by older children under the
supervision of an adult.
 Remember that coffee and espresso are not suitable drinks for
children.
 Danger of suffocation! Whilst playing, children may become
entangled in packaging material (such as plastic wrapping) or pull it
over their head with the risk of suffocation. Keep packaging material
away from children.

Warning and Safety instructions
10
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 coffee 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.

Warning and Safety instructions
11
 Only use the coffee machine in rooms where the ambient
temperature is between +16°C and +38°C.
 Do not place the coffee machine near a window in direct sunshine
or right next to an appliance that gives off heat. These would subject
the machine to ambient temperatures outside its permitted operating
range.
 Position the coffee machine at a height of at least 850mm from
the floor.
 Danger of overheating! Ensure that there is sufficient ventilation
around the coffee machine. Do not cover the coffee machine with
tea towels etc. while it is in use.
 The coffee machine must not be installed in a niche. Heat and
moisture can accumulate in a niche or a cupboard either with or
without a furniture door. This can result in damage to the appliance
and/or furniture unit.
 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.
 Miele can only guarantee the safety of the appliance when
genuine Miele replacement parts are used. Faulty components must
only be replaced by Miele original spare parts.

Warning and Safety instructions
12
 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.
 Disconnect the coffee machine from the power supply if it is not
going to be used for a while, e.g. while on holiday.
 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.

Warning and Safety instructions
13
Correct use
Danger of burning and scalding on the dispensing spouts.
The liquids and steam dispensed are very hot. Heating surfaces
have residual heat after use.
Keep well away from the area underneath the spouts when hot
liquids 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.
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:
– The water quality must conform to the requirements for drinking
water in the country in which the coffee machine is being used.
– Only use cold, fresh tap water to fill the water container. Hot or
warm water or other liquids can damage the coffee machine.
– Change the water every day to prevent a build-up of bacteria.
– Do not use carbonated water.
 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.
 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 residual moisture. These can damage the
coffee machine grinder as soon as grinding begins.

Warning and Safety instructions
14
 Do not use coffee beans which have been treated with caramel,
sugar or other substances. Sugar will damage the coffee machine.
 Only fill the coffee chute with ground coffee beans.
 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.
 If decaffeinated coffee beans are used after dispensing a drink
with caffeinated beans, there may still be residues from the
caffeinated beans in the grinder or brew chamber. Discard the first
coffee drink when using decaffeinated coffee.
 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.
 When making tea, please follow the instructions on the packaging.
 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.

Warning and Safety instructions
15
Cleaning and care
 Disconnect the coffee machine from the power supply before
cleaning.
 Clean the coffee machine and the milk flask daily, particularly
before using for the first time.
 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.
 If you do not utilise automatic descaling, you will need to descale
the coffee machine manually on a regular basis. Miele cannot be
held liable for damage resulting from not descaling the machine,
using the wrong descaling agent or an unsuitable descaling solution
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.

Warning and Safety instructions
16
The following applies to appliances with stainless steel
surfaces:
 Do not adhere stickers, adhesive tape or any other adhesive
materials to the stainless steel surfaces.
 Stainless steel scratches very easily and even magnets can cause
damage to the surface.
