~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).
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.
IMPORTANT SAFETY INSTRUCTIONS
6

~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.
Accessories
~Only specific additional equipment,
made by Miele or approved by Miele,
should be used with this machine.
Consult Miele on the type and
application of such equipment.
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.

To avoid the build-up of calcium
deposits on items being cleaned and in
the machine the water needs to be
softened.
To ensure a steady supply of soft water
the water softener unit must always be:
1. correctly set (programmed) and
2. the salt reservoir must be filled.
(If the water hardness level is below
4 gr/gal (4 °d) the water does not
need to be softened.)
The machine is set at the factory for
a water hardness level
of 20 gr/gal (19 °d).
If the water supply is harder or softer
than this (including below 4 gr/gal
(4 °d) the factory setting will need to
be changed following the
instructions in the section "Setting
the water softener". For settings see
chart on the next page.
Your local water authority will advise
you on the water hardness in your area.
For fluctuating levels (e.g.8-18gr/gal
or8-17°d)setthewater softener to
the highest setting (in this example to
18 gr/gal or 17 °d).
Important
The built-in water softener has settings
from1-62gr/gal (1 - 60 °d).
For future servicing it is useful to make
a note of your water hardness level.

Filling the salt reservoir
Please only use special coarse grained
reactivation salt with granules of
approx. 1-4 mm. Do not use other types
of salt, e.g. table salt, agricultural or
gritting salt. These could contain
components which are insoluble in
water which could result in damage to
the water softener. If in doubt consult
your Miele Professional Department.
The salt reservoir holds approx. 5.5 lbs
(2.5 kg) of salt.
,Inadvertently filling the salt
reservoir with cleaning agent will
damage the water softener.
Before filling the salt reservoir make
sure that you have picked up the
right packet of reactivation salt.
^Remove the bottom basket from the
machine.
^Unscrew the salt reservoir cap.
Before filling the salt reservoir with
reactivation salt for the first time fill it
with approx. 2 quarts (2.5 liters) of
water.
^Place the funnel provided in place.
^Fill carefully with salt, (as it is filled
water will run out).
Water softener
15

^Wipe any residual salt off the screw
threads on the socket.
^Screw the cap on firmly.
^Immediately after this: Run the
"Rinse" program to remove any traces
of salt from the cabinet.
Important:
If after starting the "Rinse" program,
the machine will not start for a few
minutes. This is not a fault. The
water softener is being reactivated.
Salt indicator
When the salt reservoir is empty the
"Recharging" indicator light bcomes
on to remind you to fill the reservoir.

Loading the machine
Preparation
^Empty all containers before loading
into the machine.
,Ensure that no acid or solvent
residues, especially hydrochloric
acid or chlorides get into the wash
cabinet.
Notes
^Load items so that water will come
into contact with all surfaces. This
ensures that they will be properly
cleaned.
^Do not place items to be cleaned
inside other pieces where they may
be concealed.
^Hollow vessels such as cups,
glasses, pots, etc. should be inverted
and placed in the correct inserts.
^Deep based items should be placed
at an angle to ensure that water runs
freely off them.
^Tall, narrow, hollow pieces should be
placed in the center of the basket to
ensure good coverage of water.
^Small pieces should be placed on
the cup racks in the upper basket.
Do not obscure them by larger items
below. Cups should be on the lower
rack and bowls on the top rack so
that water reaches all pieces.
^The water duct for the spray arm in
the middle of the upper basket must
not be covered.
^The spray arms must not be blocked
by items which are too tall or which
hang down in their path. If necessary,
manually rotate the arms to test.
Use the upper basket for:
^small, lightweight, delicate items
such as cups, saucers, glasses,
dessert bowls etc. as well as for
lightweight thermally stable plastic
items.
Use the bottom basket for:
^larger and heavier items such as
plates, serving platters, saucepans,
bowls etc. Glasses may only be
cleaned in the bottom basket if it is
fitted with a special glassware insert
or if there is a special bottom basket.
Cutlery
^Unsorted cutlery should be placed in
the cutlery holders with the handles
facing downwards.
