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 chil‐
dren) with reduced physical, sensory or mental capabilities, or lack
of experience and knowledge, unless they have been given supervi‐
sion 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
11
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, rec‐
ognising 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 open‐
ing mechanism.
 Danger of suffocation! Children may be able to wrap themselves
in packing material or pull it over their heads with the risk of suffoca‐
tion. 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 alka‐
line and contain irritants and corrosive ingredients. They can be ex‐
tremely 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. 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
12
Technical safety
 Repairs and other work by unqualified persons could be danger‐
ous. Installation, maintenance work and repairs to electrical applian‐
ces must only be carried out by a Miele approved service technician.
 Before installation, check the dishwasher for visible signs of dam‐
age. Under no circumstances should you use a damaged dishwash‐
er. 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 elec‐
trical system in the house should be checked by a qualified electri‐
cian.
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 assur‐
ed 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 discon‐
nected from the electricity supply at any time.
 There must be no electrical sockets behind the dishwasher. Dan‐
ger 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
13
 To avoid the risk of damage to the dishwasher, make sure that the
connection data on the data plate (fuse rating, voltage and frequen‐
cy) matches the mains electricity supply before connecting the dish‐
washer 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 mecha‐
nism 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 in‐
stallations (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
14
 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 30 and 1000 kPa (0.3 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 appli‐
ance when Miele replacement parts are used.
 During installation, maintenance and repair work, the appliance
must be disconnected from the mains electricity supply.
 If the connection cable is damaged, it must be replaced with a
special cable of the same type (available from Miele) by a Miele au‐
thorised service technician only in order to avoid a hazard.

Warning and Safety instructions
15
 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.
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 dishwash‐
ers must only be installed under a continuous worktop which is se‐
cured to adjacent cabinetry.
 If you want to convert your freestanding dishwasher to a built-un‐
der ("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 in‐
gredients. 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 immedi‐
ately if detergent has been swallowed or inhaled, e.g. Poisons Infor‐
mation 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 dish‐
washer 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 dish‐
washers. 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 re‐
action (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 dish‐
washer 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) cut‐
lery 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 crock‐
ery 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 mod‐
el), make sure that the dispenser is dry before adding detergent.
Wipe dry if necessary. Detergent will clog if poured into a damp dis‐
penser and may not be thoroughly dispersed.
 Please observe the information given in "Technical data" regard‐
ing the capacity of the dishwasher.
Accessories
 Use only genuine original Miele spare parts. If spare parts or ac‐
cessories from other manufacturers are used, the warranty will be in‐
validated, and Miele cannot accept liability.
Disposal of your old dishwasher
 Make the door lock inoperative so that children cannot acciden‐
tally 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 mate‐
rial
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.
The packaging consists of the following
materials:
Outer packaging:
– Corrugated cardboard made from up
to 100% recyclable material:
or: Polyethylene (PE) shrink wrap
– Polyproplylene (PP) strapping
Inner packaging:
– Chlorine and fluorine free expanded
polystyrene (EPS)
– Base, lid frame and support battens
made from untreated natural wood
from renewable forests
– Polyethylene (PE) protective wrap
Recycling the packaging reduces the
use of raw materials in the manufactur‐
ing process and also reduces the
amount of waste in landfill sites. Rather
than just throwing these materials
away, please ensure they are recycled.
Ensure that any plastic wrap‐
pings, bags, etc. are disposed of
safely and kept out of the reach of
babies and young children. Danger
of suffocation.
Disposing of your old appli‐
ance
Electrical and electronic appliances of‐
ten contain materials which, if handled
or disposed of incorrectly, could be po‐
tentially hazardous to human health and
to the environment. They are, however,
essential for the correct functioning of
your appliance. Therefore, please do
not dispose of your old appliance with
your household waste.
Please dispose of it at your local com‐
munity waste collection / recycling cen‐
tre.
Ensure that your old appliance presents
no danger to children while being stor‐
ed for disposal.
To enable sorting by type of plastic for
recycling, all plastic parts of the appli‐
ance are labelled with international
standard symbols.

Caring for the environment
19
Energy-saving dishwashing
This dishwasher is exceptionally eco‐
nomical in its use of water and electrici‐
ty.
You can make the most of your appli‐
ance 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 ener‐
gy-saving dishwashing. This pro‐
gramme is the most efficient in terms
of its combined energy and water
consumption at cleaning normally
soiled crockery.
– If your dishwasher is connected to a
hot water supply, select the SolarSave
programme for washing a lightly to
moderately soiled load. Because the
water is not heated in this pro‐
gramme, crockery may still be slightly
damper at the end of this programme
than it would be with other pro‐
grammes.
– Follow the detergent manufacturer's
recommendations on detergent dos‐
age.
– When using powder or liquid deter‐
gent you can use 1/3less detergent if
baskets are only half full.
You can find further tips on energy-
saving dishwashing in "Miele's guide
to dishwashing".

Caring for the environment

EcoFeedback consumption in‐
dicator
The Consumption function is used for
calling up information about the energy
and water consumption of your dish‐
washer (see "Settings menu - Con‐
sumption").
Three different types of information can
be displayed:
– an estimate of the consumption be‐
fore the programme begins
– the actual consumption at the end of
the programme
– the total consumption of the dish‐
washer
1. Consumption estimate:
After a programme has been selected,
first the name of the programme and,
after a few seconds, the estimated en‐
ergy and water consumption will ap‐
pear in the display.
The estimated consumption levels will
be displayed as a bar chart. The more
bars (  ) in the display, the more ener‐
gy or water will be used.
The values are influenced by the pro‐
gramme selected and any programme
options selected.
The display will change automatically to
show the time remaining.
The consumption indicator is switched
on as standard. However, you can also
switch the indicator off (see "Settings
menu - Consumption").
2. Actual consumption
At the end of the programme you can
call up the actual amount of energy and
water used by the programme which
has just been run.
Press OK when the Consumption (OK)
message appears in the display.
Switching the dishwasher off at the
end of the programme will delete the
actual consumption values for the
programme which has just been run.
3. "Consumption" setting
The Consumption setting gives a total of
the energy and water which has been
used in all previous dishwasher pro‐
grammes (see "Settings menu - Con‐
sumption").
