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 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

 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
 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 dangerous.
 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 original 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 liable 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, frequency, and fuse rating)
match those of your electrical supply.
 WARNING - Fire hazard! Do not cover or crush the plug of the appliance. 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”.
 Do not use an extension cord to connect this machine to electricity. Extension cords do
not guarantee the required safety of the machine (e.g., danger of overheating).

Important safety instructions
9
 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 wire is damaged. A damaged 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 supply.
 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.

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 example, 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
10
Correct use
 This commercial dishwasher is designed for operation with water and detergents
suitable for use in commercial or residential dishwashers only. Organic solvents and
flammable liquid agents must not be used.
This could cause an explosion, property damage due to the destruction of rubber or
plastic, and the resulting leakage of liquids.
 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 damaged.
 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 taking 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 detergents, 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 immediately and the dishwasher must be
disconnected from the mains electrical supply.
 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 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 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 inhaled.
 Miele cannot be held liable for any effect chemical detergents may have on the material
of the items being cleaned. Observe the detergent 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 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 corrosion damage.
 Be careful when sorting items with sharp pointed ends and positioning 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.

Important safety instructions
11
 Remove any coarse food deposits from the items being cleaned before loading them in
the dishwasher.
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 not be allowed to operate this dishwasher.
 Keep children away from process chemicals. These contain ingredients 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
dishwasher. Seek medical advice immediately if a child has swallowed or inhaled any
process chemicals.
Accessories
 Only use genuine Miele original spare parts and accessories with this dishwasher. Miele
will provide you with the article designations of the accessories.
 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.

Disposal of the commercial dishwasher
 For safety and environmental reasons, dispose of all process chemicals 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 failure to comply with these safety
instructions and warnings.

Caring for the environment
13
Disposal of the packing material
The cardboard box and packing materials protect the appliance
during shipping. 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. Danger 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 materials improperly by disposing of them
in your household waste can be harmful to your health and the
environment. Therefore, 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 ensure that your old appliance is kept away
from children until removal. Observe safety requirements for
appliances that may tip over or pose an entrapment hazard.
