Correct use
9
This dishwasher complies with 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 dishwasher, please read these
instructions carefully before using it for the first time. They contain important in-
formation on its safety, installation, use and maintenance. Keep these instruc-
tions in a safe place and pass them on to any future owner.
 This dishwasher with its short programme running times and
powerful cleaning performance is intended for commercial use in of-
fice kitchens, clubhouses, small businesses, active kitchens and
other similar commercial environments.
It is also suitable for use in domestic households and in similar resid-
ential environments for example by customers in hotels, motels, bed
and breakfast and other related establishments.
 The commercial dishwasher is subsequently referred to as a dish-
washer in these operating instructions.
Glasses, cutlery and crockery are referred to generally as crockery
when not more specifically defined.
 This dishwasher is not intended for continuous use.
 This dishwasher is not suitable for the reprocessing of medical
products or devices.
 This machine is designed exclusively for use as a “dishwasher” for
cleaning crockery, glassware and cutlery as described in these in-
structions. Any other use, conversions and modification are not per-
mitted 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 should only be used for their specific applica-
tion.

Correct use
10
 This dishwasher can only be used by people with reduced phys-
ical, sensory or mental capabilities, or lack of experience or know-
ledge, if they are supervised whilst using it or have been shown how
to use it in a safe way and understand and recognise the con-
sequences of incorrect operation.
 This dishwasher can only be used on a ship if
– the ship’s hull is longer than 28metres.
– the list of the vessel is not more than2°.
– any external vibration is no more than 150Hz at an amplitude of
0.35mm.
The safe operation and correct functioning of this dishwasher can

 This 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. It is not suitable for
room lighting. Replacement lamps may only be fitted by a Miele au-
thorised person or by Miele Service.

Warning and Safety instructions
11
Correct installation
 This dishwasher may only be installed and used in mobile installa-
tions such as ships if a risk assessment of the installation has been
carried out by a suitably qualified engineer.
 This dishwasher must be fixed in position when it is installed.
Failure to do this could result in personal injury, damage to the ma-
chine and damage to property.
 This dishwasher must be securely bolted to the floor using a BBF
80 kit.
 Do not install this dishwasher in an area where there is a risk of
explosion or freezing conditions.
 Take care, both before and during installation of the dish-
washer, not to cut yourself on the metal parts. Danger of in-
jury. Wear protective gloves.
 To ensure stability a built-under dishwasher must only be installed
beneath a continuous worktop that is bolted to the adjacent cabin-
etry.
 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). It is also important that the door
cannot fall open. The dishwasher must only be operated with prop-
erly adjusted door springs.

Warning and Safety instructions
12
Technical safety
 This dishwasher must only be installed, commissioned, repaired
and maintained by Miele Professional Service or a suitably qualified
service technician. Installation, repairs and other work by unqualified
persons could be dangerous. Miele cannot be held liable for unau-
thorised work.
 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
mains immediately and call Miele Professional Service or a suitably
qualified service technician.
 Faulty components must only be replaced by genuine Miele ori-
ginal spare parts. Only when these parts are fitted can Miele guaran-
tee the correct functioning and safety of the appliance.
 The electrical safety of this machine can only be guaranteed when
correctly earthed. If in any doubt, please have the electrical installa-
tion 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”.

Warning and Safety instructions
13
 Do not connect the dishwasher to the mains electricity supply via
a multi-socket unit or an extension lead. These do not guarantee the
required safety of the machine (e.g. danger of overheating).
 Warning. Do not open the casing of the dishwasher. Any contact
with live connections or tampering with the electrical or mechanical
components of the dishwasher will endanger your safety and may
lead to machine malfunctions.
 The dishwasher must not be used if the electrical connection
cable is damaged. A damaged connection cable may only be re-
placed with a specific connection cable of the same type (available
from Miele Service). For safety reasons, such replacement may only
be carried out by a qualified technician or the Miele Service.
 The dishwasher must be disconnected from the mains electricity
supply before any maintenance or repair work is carried out.
 The plastic housing of the water connection contains electrical
components. It must not be dipped in water.

Warning and Safety instructions
14
 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 are replaced
where it can be seen that this is necessary,
– the stopcock has been turned off during longer periods of inactiv-
ity (e.g. whilst on holiday).
The Waterproof system will work even when the dishwasher is
switched off. However, the dishwasher must remain connected to
the electricity supply.

Warning and Safety instructions
15
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 compon-
ents in the dishwasher and cause liquids to leak out of it.
 Only use cleaning agents formulated for use in commercial dish-
washers. Unsuitable cleaning agents could adversely affect compon-
ents 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 would 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 damaged.
 Please be aware that the dishwasher may be operating at high
temperatures. When 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 con-
tainers could still be very hot. Empty them into the wash cabinet be-
fore 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 im-
mediately and the machine must be disconnected from the mains
electrical supply.

Warning and Safety instructions
16
 When using cleaning agents and specialised products, it is essen-
tial 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 clean-
ing agents contain irritant or corrosive ingredients which can cause
burning in the nose, mouth and throat if swallowed, or inhibit breath-
ing. 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. Ob-
serve 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, lubricating grease
or paint in the dishwasher. These materials will cause damage to the
dishwasher.
 Do not clean the dishwasher or near vicinity with a hose or a pres-
sure 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 posi-
tioning them in the dishwasher that you do not hurt yourself or cre-
ate 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.

Warning and Safety instructions
17
Safety with children
 Children should be supervised in the vicinity of the dishwasher.
Never allow children to play with the machine. There is a danger that
children might shut themselves in the dishwasher.
 Children under eight years of age must be kept away from the
dishwasher unless they are constantly supervised.
 Children aged eight and older may only use the dishwasher
without supervision if they have been shown how to use it in a safe
manner. Children must be able to recognise and understand the po-
tential risks of improper use.
 If the automatic door opening mechanism is active, keep young
children away from the area in which the door opens. There is a
danger of injury in the unlikely event of a fault with the opening
mechanism.
 Keep children away from chemical agents. These contain irritant
and corrosive ingredients which can cause burning in the mouth, or
inhibit breathing. Keep children away from the dishwasher when the
door is open. There could still be residual chemical agent in the
wash cabinet. Seek medical advice immediately if a child has swal-
lowed 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 li-
ability claims will be invalidated.
Miele cannot be held liable for damage caused by non-compliance
with these Warning and Safety instructions.

Caring for the environment
18
Disposal of the packing mater-
ial
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 manufactur-
ing process and also reduces the
amount of waste in landfill sites.
Disposing of your old appli-
ance
Electrical and electronic appliances of-
ten contain valuable materials. They
also contain specific materials, com-
pounds and components, which were
essential for their correct function and
safety. These could be hazardous to hu-
man 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 com-
munity waste collection / recycling
centre for electrical and electronic ap-
pliances, or contact your dealer or
Miele for advice. You are also respons-
ible (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 appli-
ance poses no risk to children while be-
ing stored prior to disposal.

Caring for the environment
19
Economical dishwashing
This dishwasher is exceptionally eco-
nomical in its use of water and electri-
city.
You can make the most of your ma-
chine by following these tips:
– For most economical dishwashing,
make full use of the baskets without
overloading the dishwasher. This res-
ults in the most economical dish-
washing.
– Choose the programme to suit the
type of crockery being washed and
the degree of soiling.
– Select the ECO programme for en-
ergy-saving dishwashing. This pro-
gramme is the most efficient in terms
of its combined 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.

Before using for the first time
20
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 pre-
ferred (see “Settings menu, AutoOpen”).
To open the door, reach under the
door grip and pull.
Open the door completely to re-en-
gage the door closing mechanism.
If the door is opened during operation
all functions are automatically interrup-
ted.
Water in the dishwasher may be
hot. Danger of scalding.
Only open the door during operation
if absolutely necessary and exercise
extreme caution when doing so.
Keep the area around the door
free of obstructions.
Closing the door
Push the baskets right in.
Then raise the door up, and push un-
til it clicks into position.
Danger of injury.
Do not put your hand inside the door
as it is closing.
Safety lock
The child safety lock can be used to
prevent children opening the dish-
washer. The door can then only be
opened by using a lot of force.
To lock the door, push the slide un-
derneath the door grip to the right.
To unlock the door, push the slide to
the left.
