Correct application
8
This appliance complies with all current local and national safety requirements.
Inappropriate use can, however, lead to personal injury and damage to property.
Read the Operating instructions carefully before using the appliance for the first
time. They contain important information on the safety, installation, use and
maintenance of the appliance. You will prevent the risk of accidents and
damage to the commercial dishwasher. Keep these instructions in a safe place
and pass them on to any future owner.
Correct application
 This dishwasher with its short programme running times and
powerful cleaning performance is intended for commercial use in
offices, lunch rooms, clubhouses, workshops, large kitchens and
similar commercial environments.
 This dishwasher is not suitable for continuous operation.
 This dishwasher is not suitable for the reprocessing of medical
products or devices.
 This dishwasher is designed exclusively for use as a "dishwasher"
for cleaning crockery, glassware and cutlery as described in these
instructions. Alterations or conversions to the dishwasher, or using it
for purposes other than those for which it is designed, 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 should only be used for their specific
application.
 This dishwasher cannot be used by people with reduced physical,

unless they are supervised whilst using it or have been shown how
to use it in a safe way and understand and recognise the
consequences of incorrect operation.

Warning and Safety instructions
9
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

 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 maintained by Miele Professional Service or a suitably qualified
service technician. Installation, repairs 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 a damaged
appliance. A damaged appliance could be dangerous.
 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
original spare parts. Only when these parts are fitted can Miele
guarantee the safety standards of the appliance.

Warning and Safety instructions
10
 The electrical safety of this dishwasher can only be guaranteed
when continuity is complete between it and an effective earthing
system. 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 dishwasher, 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. There
is a danger of overheating and risk of fire 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).
 Never open the casing of the appliance. 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, the
replacement must only be carried out by Miele Professional Service
or a qualified electrician.
 This 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 two
electrical components. It must not be dipped in water.
 There are electrical wires in the water inlet hose. Do not cut the
hose, even if it is too long.

Warning and Safety instructions
11
 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 tap has been turned off during longer periods of inactivity (e.g.
whilst on holiday).
– Only use new hose set supplied with the appliance. Old hose sets
should not be re-used.
The Waterproof system will work even when the dishwasher is
switched off. However, the dishwasher must remain connected to
the electricity supply.
 In 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 warranty.

Warning and 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 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 which are suitable for use in a
dishwasher. Unsuitable cleaning agents could adversely affect
components of the dishwasher or the items being cleaned.
 Do not sit, stand or lean on the opened door. The dishwasher may
tip or be damaged.
 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
containers could still be very hot. Empty them into the wash cabinet
before taking them out.
 The water in the wash 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.

Warning and Safety instructions
13
 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 by
the manufacturer to avoid any material damage or the occurrence of
strong chemical reactions (e.g. oxyhydrogen explosion).
 Do not inhale or ingest powder cleaning agent. Do not swallow
dishwasher cleaning agents. They can cause burning in the nose,
mouth and throat. 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 chloride to get into the wash cabinet.
Similarly avoid any ferrous 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 hose the dishwasher or near vicinity down to clean it, e.g.
with a hose 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. Knives and other utensils with sharp
points must be loaded with the pointed end facing downwards or
placed in a horizontal position.
 Remove any coarse food deposits and empty out any containers
or utensils before loading them in the dishwasher.

Warning and Safety instructions
14
Safety with children
 Children should be supervised in the vicinity of the dishwasher. Do
not let children play with the dishwasher. There is a danger that
children might shut themselves in the dishwasher.
 Young children must not be allowed to use this appliance.
 Older children may only operate the dishwasher unsupervised if
they have been taught how to operate it safely. Children must be
able to understand and recognise the possible dangers caused by
incorrect operation.
 Keep children away from chemical agents. These contain irritant
and corrosive ingredients which can cause burning in the mouth and
throat, or inhibit breathing. Keep children away from the dishwasher
when the door is open. There could still be residual process
chemicals in the cabinet. Seek medical advice immediately if a child
has swallowed or inhaled chemical agents.
Accessories
 Only use genuine Miele spare parts and accessories with this
appliance. If spare parts or accessories from other manufacturers
are used, this will invalidate the warranty, and Miele cannot accept
liability.
Miele cannot be held liable for damage caused by non-compliance
with these Warning and Safety instructions.

Caring for the environment
15
Disposal of the packing
material
The transport and protective packaging
has been selected from materials which
are environmentally friendly for
disposal, and can normally 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. 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.
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. You are also responsible for
deleting any personal data that may be
stored on the appliance prior to
disposal. Please ensure that your old
appliance poses no risk to children
while being stored prior to disposal.

Caring for the environment
16
Energy-saving dishwashing
This dishwasher is exceptionally
economical in its use of water and
electricity. You can increase the energy
saving of the machine by following
these tips:
You can 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 water is heated by
electricity and the dishwasher is used
primarily for glassware we would
recommend connection to cold water.
Make full use of the baskets without
overloading the dishwasher. This
results in the most economical
dishwashing.
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 detergent you
can use 1/3 less detergent if baskets
are only half full.

Commissioning
20
Before using the appliance 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 the dishwasher 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 on the inner
surfaces of the machine. Mains water
with a hardness level higher than 0.7
mmol/l (4°d - German scale) must be
softened. This occurs automatically in
the integrated water softener. The water
softener requires reactivation salt. 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"
for setting 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 dishwasher must however still
be programmed for the water
hardness level in your area.
Do not fill the salt reservoir with
powder or liquid dishwasher
detergent.
Dishwasher detergent will damage
the water softener.
Only use special coarse grained
dishwasher salt for reactivation, or
pure evaporated salt.
Suitable products are available from
Miele Professional.
Other salts may contain insoluble
additives which can impair the
functioning of the water softener.
