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
commercial dishwasher for the first time. They contain important
information on the safety, use and maintenance of the appliance.
This way 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 owner.
 This Miele commercial dishwasher with its short programme
durations and powerful cleaning performance is intended for
commercial use. It can also be used on ships with a hull longer than
24 metres as well as on oil rigs.
 This commercial dishwasher is subsequently referred to as a
dishwasher in these operating instructions.
Glasses, cutlery and crockery are referred to generally as crockery
when not more specifically defined.
 This appliance is designed exclusively for use as a “dishwasher”
for cleaning loads as described in these instructions. Conversions,

Warning and Safety instructions
10
Correct installation
 This commercial dishwasher may only be installed and assembled
on ships with a hull longer than 24metres by qualified persons who
will ensure that the requirements for the safe installation of this
commercial dishwasher are met.
 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
commercial 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 this dishwasher in an area where there is a risk of
explosion or freezing conditions.
 In order to reduce the risk of damage from condensation, the
furniture in the area around the dishwasher should ideally be
designed for commercial use.
Furniture can be protected using the vapour protection set, which is
available as an optional accessory.
The vapour barrier film should be stuck under the worktop in the area
around the dishwasher door.
Technical safety
 This dishwasher must only be commissioned, repaired and
maintained by the Miele Customer Service Department, a dealer or a
suitably qualified service technician. Unauthorised installation,
maintenance and repairs can cause considerable danger for the user.
 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
dangerous.
 In the event of a damaged or leaking dishwasher, switch off at the
power supply immediately and call the Miele Customer Service
Department, a Miele dealer 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 correct functioning and safety of the appliance.
 The electrical safety of this dishwasher can only be guaranteed
when correctly earthed. If in any doubt, please have the electrical
installation tested by a qualified electrician.
 Please follow the advice on installation in these instructions and
the separate Installation diagram.

Warning and Safety instructions
11
 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 via 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 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 appliance malfunctions.
 The dishwasher must not be used if the electrical connection cable
is damaged. A damaged connection cable may only be replaced by a
suitable connection cable of the same type. For safety reasons, such
replacement may only be carried out by the Miele Customer Service
Department or a qualified service technician.
 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.
 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 that 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 stopcocks have been turned off during longer periods of
inactivity (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.
Correct use
 This dishwasher is designed for operation with water and
detergents 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.

Warning and Safety instructions
12
 Only use detergents formulated for use in commercial
dishwashers. Unsuitable detergents could adversely affect
components of the dishwasher or the load items.
 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. 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 chamber 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 appliance must be disconnected from the mains
electrical supply.
 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 detergent. Dishwasher detergent
contains 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
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 or onto the
casing. 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.

Warning and Safety instructions
13
 Do not clean the dishwasher or 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
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.
Safety with children
 Children should be supervised in the vicinity of the dishwasher.
Never allow children to play with the appliance. There is a danger that
children might shut themselves in the dishwasher.
 Children must not use the dishwasher.
 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 swallowed or
inhaled chemical agent.
Accessories
 Only use genuine Miele original spare parts and accessories with
this dishwasher. Using spare parts or accessories from other
manufacturers will invalidate the guarantee and Miele cannot accept
liability.
 Only use Miele baskets and inserts with this dishwasher. Using
baskets and inserts made by other manufacturers, or making
modifications to Miele accessories can cause unsatisfactory cleaning
results, for which Miele cannot be held liable. Any resultant damage
would not be covered by the guarantee.

Warning and Safety instructions

Disposal of your old dishwasher
 For safety and environmental reasons, dispose of all chemical
agents according to the manufacturer's instructions and to safety
regulations. Safety goggles and protective gloves should be worn.
 Remove or disable the door lock prior to disposal of the
dishwasher, so that children cannot become trapped inside (see
“Caring for the environment”).
Miele cannot be held liable for damage caused by non-compliance
with these Warning and Safety instructions.

Caring for the environment
15
Disposing of the packaging material
The packaging material is used for handling and protects the
appliance from transport damage. The packaging material used is
selected from materials which are environmentally friendly for
disposal and can generally be recycled.
Recycling the packaging material reduces the use of raw materials.
Use material-specific collection points for valuable materials and take
advantage of return options. Your Miele dealer will take the packaging
material away.
Disposing of your old appliance
Electrical and electronic appliances contain many valuable materials.
They also contain certain materials, compounds and components
which were essential for their correct functioning and safety. These
could be hazardous to human health and to the environment if
disposed of with household waste or if handled incorrectly. Please do
not, therefore, dispose of your old appliance with household waste.
Instead, please make use of officially designated collection and
disposal points to dispose of and recycle electrical and electronic
appliances in your local community, with your dealer or with Miele,
free of charge. By law, you are solely responsible for deleting any
personal data from the old appliance prior to disposal. You are legally
obliged to remove any old batteries which are not securely enclosed
by the appliance and to remove any lamps without destroying them,
where this is possible. These must be taken to a suitable collection
point where they can be handed in free of charge. Please ensure that
your old appliance poses no risk to children while being stored for
disposal.
