persons could be dangerous and may
void the warranty.
The installation of this unit in
~
non-stationary locations (e.g. ships)
must be performed by a qualified
installer or service agency, in strict
accordance with national and local
safety regulations and standards.
Before installation, make sure that
~

Only with these parts does the
manufacturer guarantee that they
comply with safety requirements.
Before installation or service,
~
disconnect the power supply to the
work area by unplugging the unit,
"tripping" the circuit breaker or
removing the fuse.
When work has been performed on
~

~
should be trained regularly.
Persons who lack physical, sensory
~
or mental abilities, or experience with
the machine should not use it without
supervision or instruction by a
responsible person.
Do not allow children to play in or
~
around the dishwasher, or to operate it.
Do not tamper with the controls.
~
BURN AND SCALD HAZARD
~
This dishwasher reaches very high
temperatures. Take care when
unloading the unit. Let baskets and
inserts cool before touching them. Any
water which may remain in containers
will be very hot and should be emptied
into the wash cabinet.
BURN HAZARD
~
The heating elements become
extremely hot during use. Do not touch
the heating elements during or directly
after the end of a program.
Take care when handling liquids
~
such as detergent, rinsing, wetting, or
neutralizing agents. These may contain
irritant or caustic ingredients. Do not
use any organic solvents. Danger of
explosion!
Follow the instructions and relevant
safety procedures carefully. Wear
protective gloves and goggles. The
manufacturer’s safety conditions must
be observed with all chemical agents.
5
IMPORTANT SAFETY INSTRUCTIONS
Under certain conditions, hydrogen
~
gas may be produced in a hot water
system that has not been used for two
weeks or more. HYDROGEN GAS IS
EXPLOSIVE. If the hot water system has
not been used for such a period, turn
on all hot water faucets and let water
flow from each for several minutes
before using the dishwasher. This will
release any accumulated hydrogen
gas. Do not smoke or use an open
flame during this time.
Avoid inhaling detergent. If
~
swallowed, it can cause burning in the
mouth and throat or inhibit breathing.
Be careful when sorting and loading
~
items to be washed: locate sharp items
so that they are not likely to damage the
door seal; and load sharp knives with
the handles up to reduce the risk of
injuries.
The water in the machine must not
~
be used as drinking water.
Do not sit or lean on the open door.
~
This could cause the machine to tip or
be damaged.
Never clean the machine or near its
~
vicinity with a water or high pressure
hose.
Only use cleaning agents
~
formulated for special processes and
approved by Miele for use with this
machine. Keep all cleaning agents out
of the reach of children. Use of
unsuitable cleaning agents could
adversely affect the
components of the machine.
Use only rinse agents for
~
commercial dishwashers. When other
rinse agents are used, there is the
danger that the rinse load and the
dishwasher might be damaged.
Pre-treatments with detergents can
~
create suds, as can certain rinsing
agents. For pre-treatment and / or
cleaning only, use low-sudsing
detergents which have been approved
by Miele. Suds can have an adverse
effect on the cleaning process.
When a chemical additive is
~
recommended on technical application
grounds (e.g. with a detergent), this
does not imply that the manufacturer of
the dishwasher takes responsibility for
the affect of the chemical on the
material of the items being cleaned.
Please be aware that changes in
formulation, storage conditions, etc.,
which may not be publicized by the
chemical producer, can have a
negative effect on the cleaning result.
Always follow the instructions of the
~
chemical manufacturer when using
detergents and special application
chemicals. Only use such chemicals for
the purpose and in the situation
specified to avoid such dangers as
chemical reactions and material
damage.
The dishwasher is designed only for
~
operation with water and additive
cleaning agents. Organic solvents must
not be used in the machine. An
explosion or machine corrosion could
occur with the use of organic solvents.
6
IMPORTANT SAFETY INSTRUCTIONS
In critical applications where very
~
stringent requirements must be met, it
is highly recommended that all relevant
factors for the process, such as
cleaning agent, quality of water, etc.,
be discussed with a Miele Application
Specialist.
The special inserts should only be
~
used for their specific application.
Do not wash plastic items unless
~
they are marked "dishwasher safe" or
the equivalent. If in doubt follow the
manufacturers recommendations.
Empty any containers or utensils
~
before arranging them in the machine.
Do not allow any remains of acids or
~
solvents, particularly hydrochloric acid
or chloride solutions, to get into the
wash cabinet. The presence of any
solvents should be minimized
(especially those in hazard class A1).
To avoid corrosion damage ensure
~
that solutions or steam containing
hydrochloric acid do not come into
contact with the steel outer casing of
the machine.
Disposal of the old machine
When disposing of your old
~
dishwasher first make it unusable.
Disconnect it from the mains power
supply, cut off the cable and plug from
the cable.
For environmental and safety
~
reasons ensure the machine is
completely drained of any residual
water and detergent. (Observe safety
regulations and wear safety goggles
and gloves).
Remove the door to the washing
~
compartment, so that children cannot
accidentally shut themselves in. Make
appropriate arrangements for the safe
and environmentally responsible
disposal of the machine.
For tank system machines ensure
~
that all water is emptied out the tank.
The manufacturer cannot be held
responsible for any damage caused
by non-observance of these
Important Safety Instructions.
Accessories
Only specific additional equipment,
~
made by Miele or approved by Miele,
should be connected to this machine.
Consult Miele on the type and
application of such equipment.

the water softener unit must always be:
1. correctly set for the water hardness
level in your area.
2. the salt reservoir must be filled.
(If the water hardness level is below
4 gr/gal (4 °d - German scale) the
water does not need to be softened.)
The machine is set at the factory for a
water hardness level of 19 gr/gal
(19°d).
If the water supply is harder or softer
than this (including below 4 gr/gal or
4 °d) the factory setting will need to
be changed. For settings see chart.

Water softener
Filling the salt reservoir
Only special, coarse-grained
reactivation salt* should be used in
this machine.
*Available from Miele. Please see
back page for contact information.
Do not use other types of salt, e.g. table
salt, agricultural or gritting salt. These
could contain components which are
insoluble in water and could damage
the water softener. If in doubt, consult
Miele’s Professional Department.
The salt reservoir holds approximately
5.5 lbs (2.5 kg) of salt.
Inadvertently filling the salt
,
reservoir with detergent will damage
the water softener.
Before filling, make sure you are
using reactivation salt.
^
Remove the bottom basket from the
machine.
^
Unscrew the salt reservoir cap.
Carefully fill the reservoir with salt.
^
Displaced water will run out as it is
being filled.
^ Wipe any residual salt off the screw
threads.
^ Screw the cap on firmly.
^ Immediately after this step: Run the
"Rinse" program to remove any traces
of salt from the cabinet.
Note: There may be a delay before the
"Rinse" program starts due to the
reactivation of the water softener.
Important: The salt container must
be filled with 0.6 gal (2.5 l) of water
before adding salt for the first
time. Water does not have to be
added with subsequent refills.
^
Place the funnel (provided) in place.
14
Salt indicator
When the salt reservoir is empty the
"Recharge" indicator, b, lights as a
reminder to fill the reservoir.
Reactivation takes place automatically
during a program. The "Recharging"
indicator, a, lights while this is
occurring.
