This appliance conforms to 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 appliance, please
read these instructions carefully
before using it for the first time. They
contain important information on its
safety, use and maintenance.
Keep these instructions in a safe
place and pass them on to any
future owner.

Correct application

~

This dishwasher is not designed for
commercial use. It is intended for use in
domestic households and in similar
working and residential environments
such as:

– Shops

– Offices and showrooms

and by residents in establishments
such as

–

Hostels and guest houses.

~

This dishwasher is not intended for
outdoor use.

~

It must only be used as a domestic
appliance 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. Miele cannot be held liable
for damage resulting from incorrect or
improper use or operation.

~

This dishwasher is not intended for
use by people with reduced physical,
sensory or mental capabilities, or lack
of experience and knowledge, unless
they are supervised whilst using it, or
have been shown how to use it
correctly by a person responsible for
their safety.

Safety with children

~

This appliance is not a toy! To avoid
the risk of injury, keep children well
away and do not allow them to play in
or around the dishwasher or to use the
controls. They will not understand the
potential dangers posed by it. They
should be supervised whenever you
are working in the kitchen. There is also
a danger that children playing might
shut themselves in the dishwasher.

~

Older children may only use the
dishwasher when its operation has
been clearly explained to them and
they are able to use it safely,
recognising the dangers of misuse.

~

Keep children away from
detergents. Dishwasher detergents
contain irritant and corrosive
ingredients which can cause burning in
the mouth, nose and throat if
swallowed, or inhibit breathing. Keep
children away from the dishwasher
when the door is open. There could still
be detergent residues in the cabinet.
Consult a doctor immediately if your
child has swallowed or inhaled
detergent.

Warning and safety instructions

6

Technical safety

~

Before setting up the appliance,
check it for any externally visible
damage. Under no circumstances
should you use a damaged appliance.
It could be dangerous.

~

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. (See "Electrical
connection").

~

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 hob. The high radiant
temperatures which are sometimes
generated by a hob 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.

~

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.

~

Before connecting the appliance,
check that the connection data on the
data plate (voltage, frequency and
connected load) match the mains
electricity supply. If in any doubt,
consult a qualified electrician.

~

The electrical safety of this
appliance can only be guaranteed if
correctly earthed. It is most important
that this basic safety requirement is
observed and regularly tested and
where there is any doubt the electrical
system in the house should be checked
by a qualified electrician.
The manufacturer cannot be held liable
for the consequences of an inadequate
earthing system (e.g. electric shock).

~

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).

Warning and safety instructions

7

~

This appliance must not be used in
a non-stationary location (e.g. on a
ship).

~

The plastic housing of the water
connection contains an electrical
component. The housing must not be
submerged in water.

~

There are electrical wires in the
water inlet hose. Never 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 stopcock 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.

~

A damaged appliance could be
dangerous. If the dishwasher gets
damaged, switch it off at the mains and
call your Miele Dealer or the Miele
Service Department.

~

Unauthorised repairs could result in
unforeseen dangers for the user, for
which Miele cannot accept liability.
Repairs should only be undertaken by a
Miele approved service technician.

~

Faulty components must only be
replaced by genuine Miele original
spare parts. Only when these parts are
fitted can the safety standards of the
appliance be guaranteed.

~

Always disconnect the dishwasher
from the electrical supply for
maintenance work (switch off at the wall
socket and remove the plug).

~

If the connection cable is damaged
it must be replaced with a special
cable, available from Miele. For safety
reasons this must only be fitted by the
Miele Service Department or a Miele
authorised service technician.

~

In countries where there are 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 guarantee.

Warning and safety instructions

Installation

~

The dishwasher must be installed
and connected in compliance with the
diagram supplied.

~

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 must be adjusted
equally on both sides. They are
correctly adjusted when the door
remains stationary when left open at
45°. It is important that the door is held
in place by the springs and cannot fall
open.

Correct use

~

Do not use solvents in the

dishwasher. Danger of explosion.

~

Do not inhale or ingest dishwasher
detergent. Dishwasher detergents
contain irritant or corrosive ingredients
which can cause burning in the nose,
mouth and throat if swallowed, or inhibit
breathing. Consult a doctor immediate

­ly if detergent has been swallowed or
inhaled.

~

Avoid leaving the door open

unnecessarily, as you could trip over 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.

~

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 severe
chemical reaction.

~

Do not fill the rinse aid reservoir with
powder or liquid detergent. This will
cause serious damage to the reservoir.

Warning and safety instructions

9

~

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!

~

Please only use special coarse
grained dishwasher salt for reactivation,
as other salts may contain insoluble
additives which can impair the
functioning of the softener.

~

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.

~

On models with "Delay start", 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.

Accessories

~

Only use genuine Miele original
spare parts and accessories with this
appliance. If spare parts or accessories
from other manufacturers are used, this
will invalidate the guarantee, and Miele
cannot accept liability.

Disposal of your old
dishwasher

~

Make the door lock inoperative so
that children cannot accidentally shut
themselves in. Make appropriate
arrangements for the disposal of the
appliance.

The manufacturer cannot be held
liable for damage caused by
non-compliance with these Warning
and Safety instructions.

Warning and safety instructions

Caring for the environment

11

Energy saving washing

This dishwasher is exceptionally
economical in its use of water and
electricity. You can make the most of
your appliance by following these tips:

^

If your water supply is suitable, this
dishwasher can be connected to hot
water 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.

^ 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 Energy save programme

for energy-saving dishwashing.

^

Follow the detergent manufacturer's
recommendations on detergent
dosage.

^

When using powder or liquid
detergent, you can use

1

/3less

detergent if baskets are only half full.

Caring for the environment

12

To open the door

^ Press the release catch inside the

door grip upwards and pull the door
open.

If the door is opened during operation
all functions are automatically
interrupted.

To close the door

^ Push the baskets right in.

^

Then lift the door upwards and push
until it clicks into position.

Safety lock

Use the safety lock to prevent children
opening the dishwasher door.

^ To lock the door, push the slide

underneath the door grip to the right.

^ To unlock the door, push the slide to

the left.

Before using for the first time

13

Water softener

In order to achieve good cleaning
results, the dishwasher needs to
operate with soft water. Hard water
results in the build-up of calcium
deposits on crockery and in the
dishwasher.
Mains water with a hardness level
higher than 0.7 mmol/l (4 °d – German
scale) needs to be softened. This takes
place automatically in the integrated
water softener.

–

The water softener requires
dishwasher salt. If you use
combination products which have
salt in them in your dishwasher, you
should still add salt to achieve
optimum results.

– The dishwasher must be

programmed for the water hardness
in your area.

– Your local water authority will be able

to advise you of the water hardness
level in your area.

Where the water hardness fluctuates
e.g. between 6.7 - 9.0 mmol/l (37 ­50 °d German scale) always
programme the dishwasher to the
higher value (9.0 mmol/l in this
example).

In the event of a fault, it will help the
service technician if you know the
hardness of your local water supply.

^

Enter the water hardness below:

mmol/l or °d

The dishwasher is set at the factory
for a hardness level of

2.2 - 2.7 mmol/l (12 - 15 °d - German
scale).

If this setting corresponds to the
hardness of your water you do not need
to do anything more.

If your water is harder or softer, you will
need to programme the water hardness
level. See following section.

Before using for the first time

14

To programme the water hardness
level

Each time a button is pressed, one of
the indicator lights will flash and light
up in the control panel. However, only
the indicator lights mentioned in the
following programming process stages
are significant.

The programming procedure can be
cancelled at any time by pressing the
K button. The procedure can then be
re-started from the beginning again.

^ Switch the dishwasher off using the

K button.

^ Press the Start/Stop button in and

whilst holding it in switch the
dishwasher on using the K button.
Keep the Start/Stop button pressed in
until the Start/Stop indicator comes
on.

If this does not happen, start the
procedure from the beginning again.

^

Press the Delay start button twice.

The lowest programme indicator
flashes twice briefly at intervals, and the
Wash/Rinse programme sequence
indicator flashes 4 times briefly at
intervals (factory default setting).

The number of times the Wash/Rinse
programme sequence indicator flashes
tells you the value which has been set
(see chart).

°d mmol/l °f Wash/Rinse

1 - 4 0.2 - 0.7 2- 7 1 short

5 - 7 0,.9 - 1.3 9- 13 2 short

8 - 11 1.4 - 2.0 14- 20 3 short

12 - 15 2.2 - 2.7 22- 27 4 short

16 - 20 2.9 - 3.6 29- 36 5 short

21 - 25 3.8 - 4.5 38- 45 6 short

26 - 30 4.7 - 5.4 47- 54 7 short

31 - 36 5.6 - 6,.5 56- 65 8 short

37 - 45 6.7 - 8.1 67- 81 9 short

46 - 70 8.3 - 12.6 83-126 1 long

^ Use the Start/Stop button to select

the number of flashes which equates
to your water hardness level.
Each press of the button moves you
up a level. When the highest water
hardness level is reached, the setting
starts from the beginning again.

Example:

If your water hardness level is

4.0 mmol/l (22 °d German scale), the
Wash/Rinse indicator should flash
briefly six times at intervals.

^

Switch the dishwasher off using the
K button.

Before using for the first time

15

Checking the programmed water
hardness level

^

Switch the dishwasher off using the
K button.

^

Press the Start/Stop button in and
whilst holding it in switch the
dishwasher on using the K button.
Keep the Start/Stop button pressed in
until the Start/Stop indicator comes
on.

^

Press the Delay start button twice.

The Wash/Rinse indicator will flash for
the number of times which corresponds
to the water hardness level which has
been set (see chart).

^ Switch the dishwasher off using the

K button.

Before using for the first time

16

Before using the appliance for
the first time you require:

–

Approx. 2 litres of water,

–

Approx. 2 kg dishwasher salt*,

–

Domestic dishwasher detergent*,

–

Rinse aid* formulated for domestic
dishwashers.

* See "Optional accessories".

Every dishwasher is tested at the
factory.
There will be residual water in the
appliance from this test. It is not an
indication that it has been used
previously.

Filling the salt reservoir

If you use combination products
which have salt in them in your
dishwasher, you should still add salt
in order to achieve optimum results
and to ensure the continued
functioning of the water softener.

If the water in your area is very soft
and constantly lower than

0.7 mmol/l (4 °d - German scale)

you do not need to add dishwasher
salt.
The water softener must, however,
still be programmed to correspond
to the water hardness level in your
area.

Important! Before filling the salt
reservoir with dishwasher salt for the
first time, you must fill it with
approx. 2 litres of water to enable
the salt to dissolve. Once the
dishwasher has been used, there is
always sufficient water in 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.

Before using for the first time

17

^

Remove the lower basket and
unscrew the salt reservoir cap.

Water or saline solution will run out
of the reservoir when the cap is
removed. It should therefore only be
removed in order to refill the salt
reservoir.

^

Fill the reservoir with approx. 2 litres
of water (first use only).

^

Place the funnel provided over the
salt reservoir and carefully fill with
salt until the reservoir is full. The salt
reservoir holds approx. 2 kg of salt
depending on the brand used.

^

Clean any excess salt from around
the reservoir opening and then screw
the cap on again firmly.

^

Run the Quick wash programme im

­mediately without any crockery in the
dishwasher to remove any traces of
salt from the cabinet (do not use the
Turbo function if your dishwasher has
this feature).

Salt indicator

^

Fill the salt reservoir with dishwasher
salt when the salt indicator light
comes on. (If it comes on during a
programme, wait until the end of the
programme).

After the reservoir has been filled, the
water softener is automatically
reactivated the next time the
dishwasher is run. The salt indicator
light may still be illuminated during this
process. It will go out once the salt
concentration has reached the correct
level.
The salt refill indicator will not come on
if the dishwasher has been
programmed for a water hardness level
of less than 0.7 mmol/l (4°d, German
scale).

,

After refilling the salt reservoir,
run the Quick wash programme
immediately without any crockery in
the dishwasher to remove any traces
of salt from the cabinet (do not use
the Turbo function if your
dishwasher has this feature).

Before using for the first time

18

Rinse aid

Rinse aid is necessary to ensure water
does not cling and leave marks on
crockery during the drying phase and
helps crockery dry faster after it has
been washed.
Rinse aid is poured into the storage
reservoir and the amount set is
dispensed automatically.

,

Inadvertently filling the rinse aid
reservoir with powder or liquid
detergent will damage the reservoir.
Only pour rinse aid formulated for
domestic dishwashers into the
reservoir.

Alternatively, it is possible to use

– Household vinegar with a max. 5%

acid content

or

– Liquid citric acid up to 10% acid

content.

The resulting rinsing and drying quality
will not, however, be as good as when
rinse aid is used.

,

Do not use vinegar with a higher
acid content (e.g. vinegar essence
25% acid). This would damage the
dishwasher.

If you only ever use combination
products containing rinse aid in your
dishwasher, you do not need to add
rinse aid.

Adding rinse aid

^ Press the button on the lid of the

rinse aid reservoir in the direction of
the arrow until the flap springs open.

Before using for the first time

19

^

Add rinse aid only until it is visible in
the opening.

The rinse aid reservoir holds approx.
110 ml.

^ Close the flap firmly so that it clicks

into place. Otherwise water can enter
the rinse aid reservoir during a
programme.

^ Wipe up any spilled rinse aid. This

prevents over-foaming occurring
during the next programme.

Rinse aid indicator

When the light comes on the reservoir
contains sufficient rinse aid for2-3
programmes only.

^

Add rinse aid in plenty of time.
