This dishwasher complies with current safety requirements.
Inappropriate use can, however, lead to personal injury and
damage to property.
To avoid the risk of accidents and damage to the dishwasher,
please read the installation plan and the operating instructions
carefully before it is installed and used for the first time. They
contain important information on its installation, safety, use and
maintenance.
Keep the installation plan and the operating instructions in a safe
place and pass them on to any future owner.
Miele cannot be held liable for damage caused by non-compliance
with this information.

Warning and Safety instructions

Correct application
 This appliance is designed for domestic use and for use in similar
environments by guests in hotel or motel rooms, bed & breakfasts
and other typical living quarters. This does not include common/
shared facilities or commercial facilities within hotels, motels or bed
& breakfasts.
 This dishwasher is not suitable for outdoor use.
 It must only be used as specified in these operating instructions
for cleaning domestic crockery and cutlery. Any other usage is not
supported by the manufacturer and could be dangerous.
 This appliance is not intended for use by persons (including
children) with reduced physical, sensory or mental capabilities, or
lack of experience and knowledge, unless they have been given
supervision or instruction concerning its use by a person responsible
for their safety, and are able to recognise the dangers of misuse.

Warning and Safety instructions
10
Safety with children
 Young children must not be allowed to use this appliance.
 Older children may only use the appliance when its operation has
been clearly explained to them and they are able to use it safely,
recognising the dangers of misuse.
 Cleaning work may only be carried out by older children under the
supervision of an adult.
 Children should be supervised to ensure that they do not play with
the appliance. Keep small children away from the appliance at all
times to avoid the risk of injury. There is the risk that children may
lock themselves in the dishwasher.
 If the automatic door opening mechanism (depending on model) is
active, keep young children away from the area in which the door
opens. Danger of injury in the unlikely event of a fault with the
opening mechanism.
 Danger of suffocation! Children may be able to wrap themselves in
packing material or pull it over their heads with the risk of
suffocation. Keep children away from any packing material.
 Keep detergent and other household agents out of the reach of
children at all times. Some dishwasher detergents are strongly
alkaline and contain irritants and corrosive ingredients. They can be
extremely dangerous if swallowed, and can cause burning in the
mouth, nose and throat, or inhibit breathing. Avoid contact with the
skin and eyes. Keep children away from the dishwasher when the
door is open. There could still be detergent residues in the cabinet or
dispenser. Check that the dispenser is empty after the completion of
a programme. Seek medical advice immediately if your child has
swallowed or inhaled detergent, e.g. Poisons Information Centre
(Australia) or National Poisons Centre (NZ).

Warning and Safety instructions
11
Technical safety
 Repairs and other work by unqualified persons could be
dangerous. Installation, maintenance work and repairs to electrical
appliances must only be carried out by a Miele approved service
technician.
 Before installation, check the dishwasher for visible signs of
damage. Under no circumstances should you use a damaged
dishwasher. A damaged dishwasher could be dangerous.
 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 regularly tested and, where there is any doubt, the
electrical system in the house should be checked by a qualified
electrician.
Miele cannot be held liable for the consequences of an inadequate
earthing system (e.g. electric shock).
 Reliable and safe operation of this dishwasher can only be
assured if it has been connected to the mains electricity supply.
 The dishwasher must only be plugged into the electricity supply
via a suitable switched socket. The electrical socket must be easily
accessible after the dishwasher is installed so that it can be
disconnected from the electricity supply at any time.
 There must be no electrical sockets behind the dishwasher.
Danger of overheating and fire risk if the dishwasher were to be
pushed up against a plug.
 The dishwasher must not be installed under a cooktop. The high
radiant temperatures which are sometimes generated by a cooktop
could damage the dishwasher. For the same reason, it should not be
installed next to open fires or other appliances which give off heat,
such as heaters etc.

Warning and Safety instructions
12
 To avoid the risk of damage to the dishwasher, make sure that the
connection data on the data plate (fuse rating, voltage and
frequency) matches the mains electricity supply before connecting
the dishwasher to the mains. Consult a qualified electrician if in any
doubt.
 Do not connect the dishwasher to the mains supply until it has
been fully installed and any adjustment has been made to the door
springs.
 The dishwasher may only be operated if the door opening
mechanism is working correctly. Otherwise there could be a risk of
injury whilst the automatic door opening mechanism (depending on
model) is active.
To check that the door opening mechanism is working correctly:
– the door springs must be adjusted equally on both sides. They
are correctly adjusted when the door remains stationary when left
half open (approx. 45° opening angle). It is also important that the
door cannot fall open.
– the door locking pins automatically retract when the door opens
at the end of the drying phase.
 Do not connect the appliance to the mains electricity supply by a
multi-socket adapter or an extension lead. These do not guarantee
the required 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).
 Do not install the dishwasher in a room where there is a risk of
frost. Frozen hoses may burst or split. The reliability of the electronic
control unit may be impaired at temperatures below freezing point.
 To avoid any damage to the appliance, the dishwasher must only
be operated when it is connected to a fully vented plumbing system.
 The plastic housing of the water connection contains an electrical
valve. The housing must not be dipped in water.

Warning and Safety instructions
13
 There are electrical wires in the water inlet hose. Do not cut the
water inlet hose, even if it is too long.
 The integrated Waterproof system offers protection from water
damage, provided the following conditions are met:
– The dishwasher is correctly installed and plumbed in.
– The dishwasher is properly maintained and parts are replaced
where it can be seen that this is necessary.
– The tap has been turned off when the appliance is not used for a
longer period of time (e.g. during holidays).
The Waterproof system will work even if the appliance is switched
off. However, the appliance must remain connected to the electricity
supply.
 The water pressure (flow pressure at the connection point) must
be between 50 and 1000 kPa (0.5 and 10 bar).
 A damaged appliance could be dangerous. If the dishwasher gets
damaged, switch it off at the mains and call Miele.
 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 spare
parts. The manufacturer can only guarantee the safety of the
appliance when Miele replacement parts are used.
 During installation, maintenance and repair work, the appliance
must be disconnected from the mains electricity supply.
 If the mains connection cable is damaged, it must be replaced
with a special cable of the same type (available from Miele) by a
Miele authorised service technician only in order to avoid a hazard.

Warning and Safety instructions
14
 This dishwasher is supplied with a special lamp (depending on
model) to cope with particular conditions (e.g. temperature,
moisture, chemical resistance, abrasion resistance and vibration).
This special lamp must only be used for the purpose for which it is
intended. It is not suitable for room lighting. Replacement lamps may
only be replaced by a Miele authorised technician.
 In areas which may be subject to infestation by cockroaches or
other vermin, pay particular attention to keeping the appliance and
its surroundings in a clean condition at all times. Any damage which
may be caused by cockroaches or other vermin will not be covered
by the warranty.

Warning and Safety instructions
15
Correct installation
 The dishwasher must be installed and connected in compliance
with the installation instructions.
 Be careful when installing the dishwasher. Wear
protective gloves to avoid injury on any sharp metal
components.
 The dishwasher must be correctly aligned to ensure problem-free
operation.
 In order to ensure stability, built-under and integrated dishwashers
must only be installed under a continuous worktop which is secured
to adjacent cabinetry.
 If you want to convert your freestanding dishwasher to a built-
under ("U") model, you will need to order the appropriate conversion
kit. If you remove the existing plinth, you must replace it with a U-
model plinth. This is necessary to avoid the risk of injury caused by
protruding metal parts.
 The door springs on either side need to be evenly adjusted. They
are correctly adjusted if the half-opened door (approx. 45° door
opening angle) remains in this position when it is released. The door
must not fall down under its own weight.
The appliance may only be used with correctly adjusted door
springs.

Warning and Safety instructions
16
Correct use
 Do not use solvents in the dishwasher. Danger of explosion!
 Do not inhale or ingest dishwasher detergent. Some dishwasher
detergents are strongly alkaline and contain irritants or corrosive
ingredients. They can be extremely dangerous if swallowed, and can
cause burning in the nose, mouth and throat, or inhibit breathing.
Avoid contact with the skin and eyes. Seek medical advice
immediately if detergent has been swallowed or inhaled, e.g. Poisons
Information Centre (Australia) or National Poisons Centre (NZ).
 Avoid leaving the door open unnecessarily as someone could trip
over it and be injured by it.
 Do not sit or lean on the opened door. This could cause the
dishwasher to tip and be damaged, and you could get injured.
 Dishes can be very hot at the end of a programme. Allow them to
cool until they are comfortable enough to handle before unloading.
 Only use detergent and rinse aid formulated for domestic
dishwashers. Do not use washing-up liquid.
 Do not use commercial or industrial detergents as these may
cause damage, and there is a risk of a severe explosive chemical
reaction (such as an explosive oxyhydrogen gas reaction).
 Do not fill the rinse aid reservoir with powder or liquid detergent.
This will cause serious damage to the reservoir.
 Inadvertently filling the salt reservoir with powder or liquid
dishwasher detergent will damage the water softener. Make sure you
have picked up the correct packet of dishwasher salt before filling
the salt reservoir!
 Only use special coarse grained dishwasher salt for reactivation.
Do not use other salts such as cooking salt, agricultural grade or
gritting salt. These may contain insoluble additives which can impair
the functioning of the water softener.

Warning and Safety instructions
17
 In an appliance with a cutlery basket (depending on model) cutlery
is cleaned and dried more efficiently if placed in the basket with the
handles downwards. However, to avoid the risk of injury, place
knives and forks etc. with the handles upwards.
 Plastic items which cannot withstand being washed in hot water,
such as disposable plastic containers, or plastic cutlery and crockery
should not be cleaned in the dishwasher. The high temperatures in
the dishwasher may cause them to melt or lose shape.
 If you use the "FlexiTimer/Delay start" option (depending on
model), make sure that the dispenser is dry before adding detergent.
Wipe dry if necessary. Detergent will clog if poured into a damp
dispenser and may not be thoroughly dispersed.
 Please observe the information given in "Technical data" regarding
the capacity of the dishwasher.
Accessories
 Use only genuine original Miele spare parts. If spare parts or
accessories from other manufacturers are used, the warranty will be
invalidated, and Miele cannot accept liability.
Disposal of your old dishwasher
 Make the door lock inoperative so that children cannot
accidentally shut themselves in. Remove or destroy the locking
bracket of the door lock, and make appropriate arrangements for the
disposal of the appliance.

Caring for the environment
18
Disposal of the packing
material
The transport and protective packaging
has been selected from materials which
are environmentally friendly for
disposal, and can normally 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.
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.

Caring for the environment
19
Energy-saving dishwashing
This dishwasher is exceptionally
economical in its use of water and
electricity.
You can make the most of your
appliance by following these tips:
– For most economical dishwashing,
make full use of the baskets without
overloading the dishwasher.
– Choose the programme to suit the
type of crockery being washed and
the degree of soiling.
– Select the ECO programme for
energy-saving dishwashing. This
programme is the most efficient in
terms of its combined energy and
water consumption at cleaning
normally soiled crockery.
– Follow the detergent manufacturer's
recommendations on detergent
dosage.
– When using powder or liquid
detergent you can use 1/3 less
detergent if baskets are only half full.
– If your household water system is
suitable, this dishwasher can be
connected to a hot water supply for
further economies. If the water is
heated by solar panels, for example,
this would be energy efficient.
However, if your water is heated by
electricity, we would recommend
connection to cold water.
You can find further tips on energy-
saving dishwashing in "Miele's guide
to dishwashing".

Before using for the first time
20
Opening the door
