This Commercial Dishwasher complies with all current local and
national safety requirements. Inappropriate use can, however, lead
to personal injury and material damage.
Read the operating instructions carefully before using the Com-
mercial Dishwasher for the first time. They contain important infor-
mation on the safety, use, and maintenance of the machine. You
will prevent the risk of accidents and damage to the Commercial
Dishwasher. Keep these operating instructions in a safe place and
pass them on to any future user.
 This Miele Commercial Dishwasher with its short program cycle
times and powerful cleaning performance is intended for commercial
use. The Commercial Dishwasher can be used on ships with a hull of
longer than 91ft (28 m), as well as on oil rigs.
 The commercial dishwasher is subsequently referred to as a dish-
washer in these operating instructions.
Glasses, cutlery and dishes are referred to generally as cookware
when not more specifically defined.
 This dishwasher is not intended for continuous use.
 This dishwasher is not suitable for cleaning medical products.
 This machine is designed exclusively for use as a “dishwasher” for
cleaning wash items as described in these instructions. Any other
use, conversions, and modifications are not permitted and could be
dangerous.
Miele cannot be held liable for damage resulting from incorrect or
improper use or operation.
 This dishwasher is intended for stationary, indoor use only.
 The special inserts are to be used for their specific purpose only.
 This Commercial Dishwasher can only be used on a ship if
– the ship’s hull is longer than 91ft (28 m)
– the list of the vessel is not more than2°.

Proper use

 The door of the Commercial Dishwasher must not be opened dur-
ing operation.
 Inappropriate use can lead to water leakage.
 The Commercial Dishwasher may not be operated on an open
deck.
 The dishwasher is equipped with a special lamp to cope with par-
ticular 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, i.e., lighting the wash
cabinet. It is not suitable for room lighting. Replacement lamps may

Proper installation
 This Commercial Dishwasher may only be installed and assem-
bled on ships with a hull longer than 91ft (28 m) by qualified persons
who will ensure that the requirements for the safe installation of this
Commercial Dishwasher are met.
 When the commercial dishwasher is being installed, it must be
equipped with a mechanism that prevents the door opening acci-
dentally while at sea.
 When installing the Commercial Dishwasher, it must be securely
fixed to the floor.
Failure to do this could result in personal injury, damage to the Com-
mercial Dishwasher, and damage to other objects and installations.
 This Commercial Dishwasher must be securely bolted to the floor
using the supplied floor anchoring kit.
 Do not install the machine in an area where a danger of explosion
or of freezing temperatures may be present.
 Be careful when installing the dishwasher. Wear protective
gloves to avoid injury on any sharp metal components.
 To ensure the stability of undercounter dishwashers, these units
may only be installed beneath a continuous countertop that is bolted
to adjacent cabinetry.
 In order to reduce the risk of damage from condensation, the fur-
niture in the area around the dishwasher should be designed for
commercial use.
 The door springs must be evenly adjusted on both sides. They are
correctly adjusted when the door remains stationary when left half
open (approx. 45° opening angle). The door must not be allowed to
fall open. The dishwasher must only be operated with properly ad-
justed door springs.

Technical safety
 Installation and repair work should be performed by a qualified
and trained service technician in accordance with local and national
safety regulations. Work by unqualified persons could be dangerous
and may void the warranty.
 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. Do not use a damaged dishwasher. This could be danger-
ous.
 In the event of a damaged or leaking dishwasher, switch off at the
power supply immediately and call Miele Technical Service, a Miele
dealer, or a suitably qualified service technician.
 Faulty components may only be replaced by genuine Miele origi-
nal parts. Only when these parts are fitted can Miele guarantee the
safety standards of the appliance.
 The electrical safety of this dishwasher can only be guaranteed
when correctly grounded. If in any doubt, please have the electrical
installation tested by a qualified electrician. Miele cannot be held li-
able for the consequences of an inadequate grounding system (e.g.,
electric shock).
 Be sure to follow the installation instructions in this manual and in
the installation diagram.
 Ensure that the connection data on the data plate (voltage, fre-
quency, and fuse rating) match those of your electrical supply.
 WARNING - Fire hazard! Do not cover or crush the plug of the ap-
pliance. Ensure that the cabinet opening for the dishwasher provides
ample space for the plug and cord. Installing the dishwasher in a
tight space may crimp the power cord or put pressure on it. See
“Electrical connection”.

Important safety instructions
11
 Do not use an extension cord to connect this machine to electric-
ity. Extension cords do not guarantee the required safety of the ma-
chine (e.g., danger of overheating).
 Do not open the casing of the dishwasher. Any contact with live
connections or tampering with the electrical or mechanical compo-
nents of the dishwasher will endanger your safety and may lead to
machine malfunctions.
 The dishwasher must not be used if the wire is damaged. A dam-
aged wire may only be replaced by a suitable wire of the same type.
For safety reasons, such replacement may only be carried out by
Miele Technical Service or a qualified service technician.
 Before servicing the appliance, disconnect it from the power sup-
ply.
 The plastic housing of the water connection contains electrical
components. It must not be dipped in water.
 There are live wires in the water intake hose. Do not shorten the
water intake hose, even if it is too long.
 The built-in Waterproof system offers reliable protection against
water damage if the following conditions are met:
– Installation has been carried out correctly.
– The dishwasher is properly maintained and parts are replaced in
case of noticeable damage.
– The faucets have been turned off during longer absences (for ex-
ample, vacation).
The Waterproof system will work even when the dishwasher is
switched off. However, the dishwasher must remain connected to
the electricity supply.

Important safety instructions
12
Correct use
 This 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.
This could cause an explosion, damage rubber or plastic compo-
nents in the dishwasher, and cause liquids to leak out of it.
 Only use cleaning agents formulated for use in dishwashers. Un-
suitable cleaning agents could adversely affect components of the
dishwasher or the items being cleaned.
 You could injure yourself on the open dishwasher door or trip over
it. Avoid leaving the door open unnecessarily.
 Do not sit, stand, or lean on the opened door. This could tip or
damage the dishwasher.
 After any plumbing work, the water pipework to the dishwasher
will need to be vented. If this is not done, components can be dam-
aged.
 Please be aware that the dishwasher may be operating at high
temperatures. When the door is opened there is a risk of burning or
scalding. Wash items, 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 tak-
ing them out.
 The water in the wash cabinet is NOT safe to drink!
 The pretreatment of items (for example with dishwashing liquid
and other detergents), but also some types of soiling and some de-
tergents, 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 chamber can cause damage to the
dishwasher. If foam escapes, the program must be canceled imme-
diately and the dishwasher must be disconnected from the mains
electrical supply.

Important safety instructions
13
 When using detergents and specialized products, it is essential
that the manufacturer's instructions are followed. Detergents must
only be used for the purpose they are designed for by the manufac-
turer to avoid any material damage or the occurrence of strong
chemical reactions (e.g., oxyhydrogen explosion).
 Do not inhale or ingest powder 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 attention immediately if detergent has been swallowed or in-
haled.
 Miele cannot be held liable for any effect chemical detergents may
have on the material of the items being cleaned. Observe the deter-
gent 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. Simi-
larly avoid any materials with a corrosive effect.
 Do not wash items soiled with ash, sand, wax, lubricating grease,
or paint in the dishwasher. These materials will cause damage to the
dishwasher.
 Do not clean the dishwasher or its near vicinity with a hose or a
pressure washer.
 Ensure that the outer casing of the machine does not come into
contact with solutions or steam containing acid to avoid any corro-
sion damage.
 Be careful when sorting items with sharp pointed ends and posi-
tioning them in the dishwasher so that you do not hurt yourself or
create a danger for others. Cutlery should be placed in baskets in
such a way that no injuries can occur.
 Remove any coarse food deposits from the items being cleaned
before loading them in the dishwasher.

Important safety instructions
14
Children in the vicinity
 Children should be supervised in the vicinity of the dishwasher.
Never allow children to play with the dishwasher. There is a danger
that children might shut themselves in the dishwasher.
 Children must be kept away from the dishwasher unless they are
constantly supervised.
 If the automatic door opening mechanism is active, keep young
children away from the area in which the door opens. There is a dan-
ger of injury in the unlikely event of a fault with the opening mecha-
nism.
 Keep children away from process chemicals. These contain ingre-
dients which can cause burning in the mouth or throat, or inhibit
breathing. Keep children away from the dishwasher when the door is
open. There could still be residual process chemicals in the dish-
washer. Seek medical advice immediately if a child has swallowed or
inhaled any process chemicals.
Accessories
 Accessories may only be fitted if approved by Miele. If other parts
are used, any warranty and product liability claims shall be void.
Miele cannot be held liable for damage caused by failure to com-
ply with these safety instructions and warnings.

Caring for the environment
18
Disposal of the packing mate-
rial
The cardboard box and packing materi-
als protect the appliance during ship-
ping. They have been designed to be
biodegradable and recyclable.
Ensure that any plastic wrappings,
bags, etc. are disposed of safely and
kept out of the reach of children. Dan-
ger of suffocation!
Disposal of your old appliance
Electrical and electronic appliances
contain valuable materials. They also
contain certain substances, compounds
and components which were essential
for the proper functioning and safe use
of the equipment. Handling these mate-
rials improperly by disposing of them in
your household waste can be harmful to
your health and the environment. There-
fore, please do not dispose of your old
appliance with regular household waste
and follow local regulations on proper
disposal.
Consult with local authorities, dealers or
Miele in order to dispose of and recycle
electrical and electronic appliances.
Miele assumes no responsibility for
deleting any personal data left on the
appliance being disposed. Please en-
sure that your old appliance is kept
away from children until removal. Ob-
serve safety requirements for appli-
ances that may tip over or pose an en-
trapment hazard.

Caring for the environment
19
Energy-saving dishwashing
This dishwasher is exceptionally eco-
nomical in its use of water and electric-
ity.
You can make the most of your ma-
chine by following these tips:
– Make full use of the baskets without
overloading the dishwasher. This re-
sults in the most economical dish-
washing.
– Choose a program that best suits the
degree of soiling and the type of
dishes being washed.
– Select the ECO program for energy-
saving dishwashing. This program is
the most efficient in terms of its com-
bined energy and water consumption
for cleaning dishes with a normal
level of soiling.
– Follow the detergent manufacturer's
recommendations on detergent
dosage.
– When using powder or liquid deter-
gent, you can use 1/3 less detergent if
baskets are only half full.

Initial commissioning
20
Opening the door
Risk of damage due to water
leakage.
The door of the commercial dish-
washer must not be opened during
operation.
Once the program has started, leave
the door closed to ensure that no
water drips out.
Risk of damage due to opening
the door accidentally.
When the commercial dishwasher is
being installed, it must be equipped
with a mechanism that prevents the
door opening accidentally while at
sea.
Bolt the door with the mechanism to
ensure no wash items or baskets fall
out of the dishwasher.
To open the door, reach under the re-
cessed grip and pull.
Keep the area around the door free
of obstructions.
Closing the door
Push the baskets in.
Then lift the door upwards and push
until it clicks into position.
Danger of crushing injuries!
Do not put your hand inside the door
as it is closing.
Child lock
The child lock can be used to prevent
children opening the dishwasher. The
door can then only be opened by using
a lot of force.
To lock the door, push the slide un-
derneath the recessed handle to the
right.
To unlock the door, push the slide to
the left.
