Correct application
8

Correct installation
~Do not install the machine in an area
where there is any danger of explosion
or of freezing conditions.
~In order to ensure stability, a
built-under or integrated commercial
dishwasher must only be installed
under a continuous worktop which is
secured to adjacent cabinetry.
~Furniture and fittings installed near
the machine must be of a commercial
standard able to withstand the effects
of steam and condensation.
Technical safety
~This commercial dishwasher must
only be installed, commissioned and
repaired by the Miele Service
Department or an authorised Miele Ser-
vice Dealer. Installation, repair and
other work by unqualified persons
could be dangerous and Miele will not
be held liable.
~The machine must be operated by
appropriately trained personnel only.
They must be instructed and trained
regularly.
~Before using the machine 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 machine, switch off at the mains
immediately and call the Miele Service
Department or an authorised Miele Ser-
vice dealer.
~Repair work to the machine can only
be carried out by the Miele Service
Department or an authorised Miele Ser-
vice Dealer. Any unauthorised work will
invalidate the guarantee.

~Before connecting the machine,
check that the connection data on the
data plate (voltage, frequency and fuse
rating) match the mains electricity
supply. If in any doubt, consult a
qualified electrician.
~There must be no electrical sockets
behind the machine. Danger of
overheating if the machine were to be
pushed up against a plug. See
"Electrical Connection".
~Do not connect the machine to the
mains electricity supply by a
multi-socket adapter or an extension
lead. These do not guarantee the
required safety of the machine (e.g.
danger of overheating).
~The machine must not be installed
under a hob. The high radiant
temperatures which are sometimes
generated by a hob could damage the
commercial 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 open the housing of the
machine. Tampering with electrical
connections or components and
mechanical parts is highly dangerous
to the user and can cause operational
faults.
~The machine 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.
~The machine must be disconnected
from the mains electricity supply before
any maintenance or repair work is
carried out. Do not reconnect it until the
maintenance or repair work has been
successfully completed.
~The plastic housing of the water
connection contains an electrical
component. The housing must not be
dipped 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 machine is correctly installed
and plumbed in.
– The machine is properly maintained
and parts are replaced where it can
be seen that this is necessary.
– The stopcock is turned off when the
machine is not used for a longer
period of time (e.g. during holidays).
~The Waterproof system will work
even if the machine is switched off.
However, the machine must remain
connected to the electricity supply.
Warning and Safety instructions
10

~In areas which may be subject to
infestation by cockroaches or other
vermin, pay particular attention to
keeping the machine 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.
Correct use
~The commercial dishwasher is
designed for operation with water and
cleaning agents suitable for use in
dishwashers only. Organic solvents and
flammable liquid agents must not be
used in this machine.
These could cause an explosion,
damage rubber and plastic
components in the machine and cause
liquids to leak out of the machine.
~Only use cleaning agents
formulated for use in dishwashers.
Using unsuitable cleaning agents could
adversely affect the components of the
machine, as well as items being
cleaned.
~Do not sit or lean on the opened
door. This could cause the machine to
tip up and be damaged or cause an
injury.
~After any plumbing work the water
pipework to the machine 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
temperaures. 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
machine. If foam escapes from the
machine the programme must be
cancelled immediately.
~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 specifed, to
avoid such dangers as chemical
reactions and material damage.
Warning and Safety instructions
11

~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. Seek medical advice imme-
diately if detergent has been swallowed
or inhaled. Follow the detergent
manufacturer's safety instructions.
~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 chloride to get into
the wash cabinet. Similarly avoid any
materials with a corrosive effect.
~Do not clean the machine or near
vicinity with a water hose or a pressure
washer.
~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 any containers or utensils
before loading them in the dishwasher.
Safety with children
~Supervise children when they are
anywhere near the commercial
dishwasher. Do not allow them to play
with it. There is a danger that children
playing might shut themselves in the
dishwasher.
~Do not allow children to operate the
commercial dishwasher.
~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.
Seek medical advice immediately if a
child has swallowed or inhaled
detergent.
Accessories
~Only use genuine Miele original
spare parts and accessories with this
commercial dishwasher. Using spare
parts or accessories from other
manufacturers will invalidate the
guarantee, and Miele cannot accept
liability.
The manufacturer cannot be held
liable for damage caused by
non-compliance with these Warning
and Safety instructions.

Disposal of the packing
material
The transport and protective packing
has been selected from materials which
are environmentally friendly for disposal
and should be recycled.
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.
The packaging consists of the following

Disposing of your old machine
Electrical and electronic machines
often contain materials which, if
handled or disposed of incorrectly,
could be potentially hazardous to
human health and to the environment.
They are, however, essential for the
correct functioning of your machine.
Please do not therefore dispose of it
with your household waste.
Please dispose of it at your local
community waste collection / recycling
centre or contact your dealer for
advice.
Ensure that it presents no danger to
children while being stored for
disposal.

Energy saving dishwashing
This commercial dishwasher is
exceptionally economical in its use of
water and electricity. You can make the
most of your machine by following
these tips:
^If your water supply is suitable, this
commerical 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 and the dishwasher is
going to be used primarily for
glasses 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 ECO programme for
energy-saving dishwashing.
This Standard 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 1/3less
detergent if baskets are only half full.
Caring for the environment
14

To open 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 menu,
AutoOpen").
^Reach under the door grip and pull
the door open.
If the door is opened during operation,
all functions are automatically
interrupted.
,Keep the area around the door
free of obstructions.
To close the door
^Push the baskets right in.
^Then raise the door up, and push
until it clicks into position.
,Do not put your hand inside the
door as it is closing. Danger of
injury.
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

Before using for the first time
17

Before using the machine for
the first time, you require:
–approx. 1 kg dishwasher salt for
reactivation,
–approx. 110 ml 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 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 must
be filled with dishwasher salt for
reactivation. The water softener is
suitable for a water hardness level of up
to 6.5 mmol/l (36 °d - German scale).
See "Settings menu, Water hardness
level" for information on programming
the water softener to the water
hardness level in your area.
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.
,Do not fill the salt reservoir with
powder or liquid dishwasher
detergent. This 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, as
other salts may contain insoluble
additives which can impair the
functioning of the water softener.
Before using for the first time
18

^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.
The flap will spring open.
^Lift up the funnel.
Do not fill the salt reservoir with
water.
^Add salt only until the reservoir is full.
The salt reservoir holds approx. 1 kg
of salt, depending on the brand
used.
Do not add any more than 1 kg of
salt.
As the salt reservoir is filled, displaced
water can overflow.
^Clean any excess salt from around
the reservoir opening, and then close
the flap.
^Run the Pre-wash programme imme-
diately without any crockery in the
dishwasher to remove any traces of
salt from the cabinet.
Before using for the first time
19

"Add salt" message
^Fill the salt reservoir with dishwasher
salt for reactivation when the FAdd
salt message appears. (If it appears
during a programme, wait until the
end of the programme).
^Confirm by pressing the middle
button.
The "Add salt" message will go out.
After the salt reservoir has been filled,
the "Add salt" message may still appear
in the display if the salt concentration
has not yet reached the correct level.
If this is the case, press the middle
button again.
The "Add salt" message will not appear
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 Pre-wash or Short
programme immediately (without
any crockery in the dishwasher) to
remove any traces of salt from the
cabinet.
