Proper use
~Repair of the commercial
dishwasher during the warranty period
should be performed only by a
customer service center authorized by
the manufacturer, otherwise any
damage will not be covered by the
warranty.
~Always exercise care when handling
liquid cleaning agents or additives.
Some of these products contain
corrosive and irritating substances.
NEVER use organic solvents since
there is a risk of explosion.
ALWAYS observe the applicable safety
regulations. Use safety glasses
and gloves. Always follow the
manufacturer's safety
recommendations when using chemical
additives.
~The water in the wash cabinet is
NOT safe to drink.
~Avoid inhaling powdered cleaning
agents.
If detergents are swallowed, this can
result in chemical burns to the mouth
and throat or even suffocation.
~Certain pre-treatments (for example,
that contain detergents), as well as,
certain contaminants and some
dishwashing liquids, can generate
foam. Foam can adversely affect the
cleaning performance.
~The recommendation to use
chemical additives (such as cleaning
agents) does not mean that the washer
manufacturer accepts liability for how
these chemical additives may affect the
wash load.
Note that formulation changes, storage
conditions, etc., not disclosed by the
manufacturer, may alter the cleaning
results obtained.
~When using cleaning agents and
special-purpose products, comply
strictly with the instructions of the
respective manufacturer. In order to
avoid possible chemical reactions
(such as explosive hydrogen gas
reactions), use cleaning agents only for
the applications intended by the
manufacturer.
~The commercial dishwasher is
designed only for operation with water
and additive cleaning agents. Organic
solvents must NOT be used in the
appliance, as there is the danger of
explosion and/or damage.
(Note: Although many organic solvents
do not involve a danger of explosion,
they may still cause other problems,
such as the destruction of rubber and
plastics.)
~For critical applications, where very
high processing-quality requirements
have to be met, it is strongly
recommended that all process-related
factors (cleaning agents, water quality,
etc.) be discussed in advance with
Miele's Application Technology.
Safety instructions and warnings
6

~Ensure that no appreciable residues
of solvents or acids, and especially of
hydrochloric acid or chloride solutions,
are introduced into the wash cabinet
along with the wash load. This also
applies for corrosive ferrous material.
Solvents combined with contaminants
(especially from hazard class A1)
should be present in trace amounts
only.
~To avoid corrosive damage, make
sure the stainless steel housing (if
present on your model) does not come
into contact with solutions/steam
containing hydrochloric acid.
~After work has been performed on
the supply plumbing, the supply line to
the commercial dishwasher must be
vented.
Failure to do so can result in damage to
the water-intake components.
~NEVER hose down the commercial
dishwasher or the immediate vicinity,
for instance with a water hose or
pressure washer.
~Do not stand or sit on the open door,
as this could damage the commercial
dishwasher or cause it to tip over.
~Be aware of the potential for injury
when utensils with sharp, pointed ends
are placed upright, and position them
so they cannot cause injury.
~When operating the commercial
dishwasher in the upper temperature
range, proceed with caution. Be aware
of the danger of scalding or burning
when opening the door. Allow baskets
and inserts to cool off. Empty any hot
water remaining in hollow items into the
wash cabinet.
~When opening the door during or
after the end of the program, take care
not to touch the heating elements or
heated surfaces on the floor of the
wash cabinet. They remain hot for quite
a few minutes after the program has
ended and can cause burns.
~Empty all hollow items before
loading them.
Safety instructions and warnings
7

Proper installation
~The installation and operation of this
commercial dishwasher in non-
stationary locations should be
performed by specialized technicians
only and then only if they ensure that
the requirements for the safe use of the
appliance have been met.
~Do NOT install the commercial
dishwasher in an area where there may
be the danger of explosion or freezing.
~To ensure the stability of under-
counter dishwashers and integrated
under-counter dishwashers, they must
only be installed beneath a continuous
worktop that is bolted to the adjacent
cabinetry.
Children in the vicinity
~Always supervise any children in the
vicinity of the commercial dishwasher.
Never allow children to play with the
commercial dishwasher.
~Children must only be allowed to
use the commercial dishwasher without
supervision if the operation of the
dishwasher has been explained to them
in such a way that they can safely
operate it. Children must be able to
recognize the potential hazards of
improper operation.
~Do not allow small children to play
with the commercial dishwasher or to
operate it. Among other hazards,
children run the risk of locking
themselves in the dishwasher.
Accessories
~Accessories may only be attached
or installed if they have been expressly
approved by Miele. If other parts are
attached or installed, claims under the
warranty and/or product liability
become null and void.
~Whatever the application, only Miele
accessories should be connected to
this machine. Miele application
advisors can provide you with the item
names and numbers for accessories.
Disposal of the
commercial dishwasher
~For safety and environmental
protection, dispose of all detergent
residues in compliance with safety
regulations (use safety glasses and
gloves).
Remove or destroy the door latch to
prevent children from locking
themselves inside. Then dispose of the
commercial dishwasher properly (see:
Caring for the environment).
For commercial dishwashers with a
tank system, the water must first be

In order to achieve good cleaning
results, the dishwasher needs to
operate with soft water. Hard water
results in the build-up of calcium
deposits on cookware and in the
dishwasher.
Water with a hardness level higher than
4 gr/gal (4° d – German scale) needs to
be softened. This takes place
automatically in the integrated water
softener.
–The water softener requires
dishwasher reactivation salt.
–The dishwasher must be
programmed for the water hardness
in your area.
– Your local water authority can advise
you of the water hardness level in
your area.
Where the water hardness fluctuates
e.g. between8-18gr/gal (8 - 17 °d
German scale) always program the
dishwasher to the higher value (17°d in
this example).
If the water in your area is very soft
and consistently lower than 4 gr/gal
(4 °d) you do not need to add
dishwasher salt. The salt indicator,
however, will still come on, but
should be ignored.
Local water hardness:
gr/gal or °d
The dishwasher is programmed at
the factory for a water hardness level
of 20 gr/gal (19 °d).
If this setting corresponds with the
hardness of your water, continue with
"Rinse aid".
If your water is harder or softer, you will
need to program the water hardness
level using the buttons on the control
panel.
The programming can be canceled
at any time by pressing the "On/Off"
button. The procedure can then be
restarted.
Checking the programmed water
hardness level
^Turn the dishwasher off with the
"On/Off" button.
^Press and hold the "Extra drying"
and "Start / Stop" buttons in and turn
the dishwasher on with the "On/Off"
button.
^Release the buttons.
The hardness level set will flash in the
display.
The digit sequence after the a
indicates the hardness level set in °d.
^Turn the dishwasher off with the
"On/Off" button.

Filling the salt reservoir
Only special, coarse-grained
reactivation salt* should be used in
this machine.
*Available from Miele. Please see
back page for more 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
the Miele Professional Department.
The salt reservoir holds about 2 kg of
salt.
,Inadvertently filling the salt
reservoir with detergent will damage
the water softener.
Before filling, make sure that you are
using reactivation salt.
^Remove the lower basket.
^Unscrew the salt reservoir cap.
,Filling the salt reservoir with
salt for the first time:
Fill the reservoir with approx. 2 liters
of water first.
^Place the supplied funnel over the
salt reservoir.
^Carefully fill with reactivation salt.
Displaced water will run out as it is
being filled.
Water softener
16

^Clean any excess salt from the
thread and seal.
^Screw the cap on firmly.
^Close the door.
^Immediately run the "Pre-wash"
program to remove any traces of salt
from the cabinet.
Recharge indicator
The reactivation salt needs to be
replenished when the "Recharge"
indicator lights.
After the reservoir has been filled, the
water softener is automatically
reactivated the next time the
dishwasher is run. The salt indicator
may still light during this process. It will
go out once the salt concentration has
reached the correct level.

Rinse aid is needed to prevent spotting
on dishes and glassware. The rinse aid
is filled in the reservoir and the set
amount will be automatically dispensed
during the final rinse.
,Inadvertently filling the rinse aid
reservoir with powder or liquid
detergent will damage the reservoir.
Only pour rinse aid formulated for
household dishwashers into the
reservoir.

^Press the button of the rinse aid
reservoir flap in the direction of the
arrow until the flap springs open.
^Add rinse aid until it is visible on the
surface of the filter in the opening.
The rinse aid reservoir holds approx.
130 ml.
^Close the flap firmly so that it clicks
into place otherwise, water will enter
the rinse aid reservoir during the
program.
^Clean up any spilled rinse aid. This
prevents over-foaming from
occurring during the next program.
Rinse aid
18

Rinse aid indicator
^Fill the rinse aid reservoir when the
"Rinse aid" indicator comes on. There
will be enough rinse aid left for2-3
wash programs.
Setting the rinse aid dosage
The dosage selector has settings from
1-6. It is factory set to the
recommended setting "3" (3 ml).
Approx. 3 ml of rinse aid are used per
program.
If spots appear on cookware and
glassware
^Use a higher setting.
If clouding or smearing appears on
cookware and glassware
^Use a lower setting.
Rinse aid
19

Loading the machine
Removing excess soils
^Scrape food from dishes before
placing them in the dishwasher.
Inadequate pre-cleaning can clog
the filters and interrupt the wash
program.
Important
–Select baskets and inserts which are
appropriate for the application.
–Load items so that water can reach
all surfaces.
– Do not place dishes or cutlery inside
other pieces.
– Hollow items such as cups, glasses,
pots, etc. should be placed upside
down in the respective inserts.
Hollow vessels should be inverted
and placed in the correct inserts.
– Concave based items such as mugs
or bowls, should be placed at an
angle so that water does not pool.
–To ensure good water coverage, tall,
narrow and hollow items should be
placed in the center of the baskets
rather than in the corners. Do not
obscure them with larger items
below.
–The spray arms must not be blocked
by items that are too tall or hang
through the baskets. Check
clearance by manually rotating the
spray arms.
–Small items should be placed on the
cup racks in the upper basket. Do
not obscure them with larger items
below, e.g. place bowls on the rack
above the cups so that water
reaches all items.
–Do not place very tall items in the
front right hand area of the lower
basket as these would prevent the
detergent dispenser lid from
opening.
–Cutlery can be placed in any order in
the cutlery holders however, for the
best cleaning and drying results,
place the cutlery in the inserts with
the handles down.
,Be careful when sorting items
with sharp pointed ends. Position
them in the machine so 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.
