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, or contact your dealer or

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.
 To avoid the risk of damage to the machine, make sure the
connection 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
guaranteed when 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.
 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
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 damage the machine.
 Only use the coffee machine in rooms where the ambient
temperature is between +16°C and +38°C.

Warning and Safety instructions
11
 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. Please ensure that there is adequate
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. 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.
 While the machine is under warranty, repairs should only be
undertaken by a Miele authorised service technician. Otherwise the
warranty is invalidated.
 Miele can only guarantee the safety of the appliance when
genuine original Miele replacement parts are used. Faulty
components must only be replaced by genuine Miele original spare
parts.
 The coffee machine must be disconnected from the electricity
supply during repair work.
 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.

Warning and Safety instructions
12
 Only use genuine original Miele accessories with this machine.
Using spare parts or accessories from other manufacturers will
invalidate the guarantee, 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.
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.
Danger 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:
– 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/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.
 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 including sugary liquids. 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.
 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.
 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
 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 use a steam cleaner to clean this machine. Steam could
reach 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
For machines with stainless steel surfaces:
 Do not use sticky notes, transparent adhesive tape, masking tape
or other types of adhesive on the stainless steel surfaces.
 Stainless steel surfaces are susceptible to scratching. Even
magnets can cause scratches.
