Warning and Safety instructions
12
Correct installation
 This 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 dishwasher are met.
 When installing the dishwasher, it must be securely fixed to the floor.
Failure to do this could result in personal injury, damage to the dishwasher and damage to
other objects and installations.
 This dishwasher must be securely bolted to the floor using the floor anchoring kit
included.
 Do not install this dishwasher in an area where there is a risk of explosion or freezing
conditions.
 To ensure stability a built-under dishwasher must only be installed beneath a continuous
worktop that is bolted to the adjacent cabinetry.
 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.
 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 operating instructions and the
installation plan.
 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 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.
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.
 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.
 There may be a risk of slipping if liquid is spilt on the floor depending on the type of
flooring and footwear being worn. Keep the floor dry where possible and take care to clean
up any liquid spills straight away. Take the necessary precautions when cleaning up
hazardous substances and hot liquids.

Warning and Safety instructions
14
 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).
 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.
 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.
 The grille of dishwashers with active drying must not be blocked or sealed.
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
15
Warning signs and symbols attached to the dishwasher
Warning:
Observe the operating instructions!
Warning:
Danger of electric shock!
Warning: Hot surfaces:
It can be very hot inside the wash cabinet when the door
is opened!
Risk of being cut:
Wear cut-resistant protective gloves when transporting

Disposal of your 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.
 Render the door lock inoperable to prevent children from accidentally locking
themselves inside the machine. Ensure a safe removal and proper disposal of the
dishwasher (see “Caring for the environment”).

Caring for the environment
16
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.
