8
Warning and Safety instructions
Correct installation
Do not install this dishwasher in an area where there is a risk of
explosion or freezing conditions.
To ensure the stability of built-under dishwashers, they must only
be installed beneath a continuous worktop that is bolted to the
adjacent cabinetry.
In order to reduce the risk of damage from condensation, the
furniture in the area around the dishwasher should be designed for
commercial use.
Technical safety
This dishwasher must only be installed, commissioned, repaired
and then maintained by the Miele Service Department or an
authorised Miele Service dealer. Installation, repair and other work
by unqualified persons could be dangerous and Miele will not be
held liable.
This dishwasher must only be operated by appropriately trained
personnel. They must be instructed and trained regularly.
Before using the dishwasher, check it for any externally visible
damage. Under no circumstances should you use it if it has been
damaged. It could be dangerous.
In the event of a damaged or leaking dishwasher, switch off at the
mains immediately and call the Miele Service Department or an
authorised Miele Service dealer.
Faulty components must only be replaced by genuine Miele
original spare parts. Only when these parts are fitted can Miele
guarantee the correct functioning and safety of the appliance.
9
Warning and Safety instructions
The electrical safety of this dishwasher 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. Miele cannot be held
liable for the consequences of an inadequate earthing system (e.g.
electric shock).
Please follow the advice on installation in these instructions and
the separate Installation diagram.
Before connecting the appliance, ensure that the connection data
on the data plate (voltage, frequency and fuse rating) match the
mains electrical supply.
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 (see "Electrical connection").
Do not connect the dishwasher to the mains electricity supply by
a multi-socket unit or an extension lead. These do not guarantee the
required safety of the appliance (e.g. danger of overheating).
Do not open the dishwasher casing. Tampering with electrical
connections or components and mechanical parts is highly
dangerous to the user and can cause operational faults.
The dishwasher must not be used if the electrical connection
cable is damaged. If the cable is damaged it must be replaced with a
special cable available from Miele. For safety reasons this must only
be done by the Miele Service Department or an authorised Miele
Service dealer.

There are electrical wires in the water inlet hose. Do not shorten
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:
– installation has been carried out correctly,
– the dishwasher is properly maintained and parts replaced where it
can be seen that this is necessary,
– the stopcock has been turned off during longer periods of
inactivity (e.g. whilst on holiday).
The Waterproof system will work even if the dishwasher is switched
off. However, the dishwasher must remain connected to the
electricity supply.
11
Warning and Safety instructions
Correct use
This dishwasher is designed for operation with water and cleaning
agents suitable for use in commercial dishwashers only. Organic
solvents and flammable liquid agents must not be used in it.
This could cause an explosion, damage rubber or plastic
components in the dishwasher and cause liquids to leak out of it.
Only use cleaning agents formulated for use in commercial
dishwashers. Using unsuitable cleaning agents could adversely
affect components in the dishwasher, as well as items being
cleaned.
Do not sit or lean on the opened door. This could cause the
dishwasher to tip up and be damaged or cause an injury.
After any plumbing work the water pipework to the dishwasher will
need to be vented. If this is not done, components can be damaged.
Please be aware that the dishwasher may be operating at high
temperatures. If the door is opened there is a danger of burning or
scalding. Crockery, cutlery, baskets and inserts must be allowed to
cool down before they are unloaded. Any water remaining in
containers could still be very hot. Empty them into the wash cabinet
before taking them out.
The water in the cabinet must not be used as drinking water.
Pre-treating items (for example with washing-up liquid and other
cleaning agents) as well as some types of soiling and some cleaning
agents can cause a build-up of foam in the wash cabinet. Foam can
have an adverse effect on the cleaning result.
Foam escaping from the wash cabinet can cause damage to the
dishwasher. If foam escapes the programme must be cancelled
immediately and the machine must be disconnected from the mains
electrical supply.
12
Warning and Safety instructions
When using cleaning agents and specialised products, it is
essential that the manufacturer's instructions are followed. Cleaning
agents must only be used for the purpose they are designed for and
in the situation specified, to avoid such dangers as serious chemical
reactions and material damage (e.g. oxyhydrogen explosion).
Do not inhale or ingest powder cleaning agent. Dishwasher
cleaning agents contain irritant or corrosive ingredients which can
cause burning in the nose, mouth and throat if swallowed, or inhibit
breathing. Seek medical attention immediately if cleaning agent has
been swallowed or inhaled.
Miele cannot be held liable for any effect chemical cleaning
agents may have on the material of the items being cleaned.
Observe the cleaning agent manufacturer's instructions with regard
to storage conditions, use and dosage.
To avoid material damage and corrosion, do not allow any acids
or solutions containing chlorides or metals which are not rust-proof
to get into the wash cabinet.
Do not wash items soiled with ash, sand, wax, grease or paint in
the dishwasher. These substances could damage the dishwasher.
Do not hose the dishwasher or near vicinity down to clean it, e.g.
with a hosepipe or a pressure washer.
Ensure that the stainless steel outer casing of the appliance does
not come into contact with solutions or steam containing acid to
avoid any corrosion damage.
Be careful when sorting items with sharp pointed ends and
positioning them in the dishwasher that you do not hurt yourself or
create a danger for others. Sharp knives, forks, etc. should be
placed in baskets with the pointed ends facing downwards.
Remove any coarse food deposits and empty out any containers
or utensils before loading them in the dishwasher.
13
Warning and Safety instructions
Safety with children
Supervise children when they are anywhere near this dishwasher.
Do not let them play with it. There is a danger that children playing
might shut themselves in the dishwasher.
Children under 8 years of age must be kept away from the
dishwasher unless they are constantly supervised.
Children aged eight years and older may only operate the
dishwasher unsupervised if they have been taught how to operate it
safely and understand the dangers of incorrect use.
Keep children away from chemical agents. These 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 residual chemical agent in the cabinet. Seek medical advice
immediately if a child has swallowed or inhaled chemical agent.
Accessories
Accessory parts may only be fitted when expressly approved by
Miele. If other parts are used, warranty, performance and product
liability claims will be invalidated.
Miele cannot be held liable for damage caused by non-compliance
with these Warning and Safety instructions.
14
Caring for the environment
Disposal of the packing material
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.
Recycling the packaging reduces the
use of raw materials in the
manufacturing process and also
reduces the amount of waste in landfill
sites.
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, or contact your dealer or
Miele for advice. You are also
responsible (by law, depending on
country) for deleting any personal data
that may be stored on the appliance
being disposed of. Please ensure that
your old appliance poses no risk to
children while being stored prior to
disposal.
15
Caring for the environment
Energy-saving washing
This dishwasher is exceptionally
economical in its use of water and
electricity. You can make the most of
your machine by following these tips:
You may connect the dishwasher to a
hot water supply. This is particularly
suitable with energy-saving water
heating sources such as solar energy
systems. If the hot water system is
electrically heated and if loads
consist primarily of glassware we
recommend connecting the machine
to the cold water supply.
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.
When using powder detergent you
can use 1/3 less detergent if baskets
are only half full.
Follow the detergent manufacturer's
recommendations on detergent
dosage.
16
Commissioning
Opening the door
At the end of programmes with a drying
phase (see "Programme chart"), the
door will open automatically a little in
order to help the drying process.
This function can be deactivated, if
preferred (see "Settings, AutoOpen").
To open the door, reach under the
door grip and pull.
If the door is opened during operation
all functions are automatically
interrupted.
Closing the door
Push the baskets right in.
Then raise the door up, and push

18
A tick will appear beside the option
which is currently selected.
Commissioning
Standard settings
Switch the dishwasher on with the
button.
If the dishwasher is being switched on
for the first time, the welcome screen
will appear.
Language
The display will then change
automatically to the screen for setting
the language.
See "Display" for more information
about the display and controls.

press the middle button to confirm.
A tick will appear next to the
language that has been set.
Water hardness
The display will change to the screen
for setting the water hardness.
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 programmed at the
factory for a water hardness level of
2.7mmol/l (15 °d - German scale).
Select the water hardness level for
your water supply and confirm with
the middle button.
See "Settings menu, Water hardness"
for more information.
The following two messages Add
rinse aid and Add salt may then appear
in the display.
Press any button to confirm these
messages. The display will change to
show the main menu.
– The dishwasher must be
programmed for the water hardness
level 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 3.1 and 4.5mmol/l (17 25 °d - German scale) always
programme the dishwasher to the
higher value (4.5mmol/l or 25 °d in
this example).
19
Commissioning
Before using the machine for the first time, you will need:
– approx. 1kg dishwasher salt,
– approx. 110ml rinse aid,
– Dishwasher detergent, see
"Operation".
Every dishwasher is tested at the
factory. There will be residual water in
the machine from this test. It is not an
indication that it has been used
previously.
Filling the salt reservoir
In order to achieve good cleaning
results, the dishwasher needs to
operate with soft water. Hard water
results in a build-up of calcium deposits
on crockery and in the dishwasher.
Mains water with a hardness level
higher than 0.7mmol/l (4 °d - German
scale) needs to be softened. This takes
place automatically in the integrated
water softener. The water softener in
the dishwasher is suitable for a water
hardness level of up to 6.5mmol/l (36°d
- German scale).
If the water in your area is very soft
and constantly lower than 0.7mmol/l
(4 °d - German scale) you do not
need to add dishwasher salt.
The dishwasher must however still
be programmed for the water
hardness level in your area.
Do not fill the salt reservoir with
powder or liquid detergent.
Dishwasher detergent will damage
the water softener.
Only use special coarse grained
dishwasher salt for reactivation, or
pure evaporated salt.
Miele Professional offer appropriate
products.
Other salts may contain insoluble
additives which can impair the
functioning of the water softener.
See "Settings menu, Water hardness"
for more information.
20
When filling the salt reservoir only
open the door halfway to ensure
that all the salt gets into the reservoir.
Press the button on the lid of the salt
reservoir in the direction of the arrow
until the flap springs open.
Commissioning
Add salt only until the reservoir is full.
The salt reservoir holds approx. 1kg
of salt, depending on the type of salt
used.
Do not add any more than 1kg of
salt.
As the salt reservoir is being filled,
displaced water may run out.
Lift up the funnel.
Do not fill the reservoir with water.
Clean any excess salt from around
the reservoir opening, and then close
the flap.
Run the "Pre-wash" programme
immediately without a load in order to
remove any traces of salt from the
cabinet.
21
Commissioning
Add salt reminder
When Add salt appears in the
display wait until the end of the
programme and then refill the salt
reservoir.
Press the middle button to confirm.
The refill reminder will go out.
After the salt reservoir has been filled,
the refill reminder may still appear in the
display if the salt concentration has not
yet reached the correct level. If this is
the case, confirm again with the middle
button.
The salt refill reminder is deactivated if
the dishwasher is set to a water
hardness of less than 0.7mmol/l (0 - 4
°dH).
Run the "Pre-wash" or the
"Short" programme immediately
without a load in order to remove any
traces of salt from the cabinet.
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.
Fill the reservoir with rinse aid
only. Do not fill it with washing-up
liquid or cleaning agent.
This would damage the rinse aid
reservoir.
Suitable products are available from
Miele Professional.
Alternatively household vinegar with a
max. 5% acid content or liquid citric
acid with a max. 10% acid content can
be used. The resulting rinsing and
drying quality will not, however, be as
good as when rinse aid is used.
22
Do not use vinegar with a higher
acid content (e.g. vinegar essence
25% acid).
This would damage the dishwasher.
Commissioning
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.
Wipe up any spilled rinse aid. This
prevents over-foaming occurring
during the next programme.
You can adjust the rinse aid dosage
for best results (see "Settings menu,
Rinse aid").
Rinse aid refill reminder
When the Add rinse aid message
appears, the reservoir contains
sufficient rinse aid for 2 - 3 programmes
only.
Add rinse aid in plenty of time.
Press the middle button to confirm.
The refill reminder will go out.
Add rinse aid only until it is visible in
the opening.
The reservoir holds approx. 110ml.
Close the flap firmly so that it clicks
into place. Otherwise water can enter
the rinse aid reservoir during a
programme.
