IMPORTANT SAFETY INSTRUCTIONS
Installation
The dishwasher must be installed
and connected in compliance with
the installation instructions.
Installation and repair work should
be performed by a Miele
authorized service technician. Work by
unqualified persons could be
dangerous and may void the warranty.
Do not install or use a damaged
dishwasher. A damaged appliance
is dangerous. Unplug the machine and
call your Miele dealer or the Miele
Technical Service Department.
Ensure that any plastic wrappings,
bags, etc. are disposed of safely
and kept out of the reach of children.
Danger of suffocation!
This equipment is not designed for
maritime use or for use in mobile
installations such as recreational
vehicles or aircraft. However, under
certain conditions it may be possible for
an installation in these applications.
Please contact the nearest Miele dealer
or the Miele Technical Service
Department with specific requirements.
It is recommended that the
dishwasher only be connected to
the mains with the plug (no
hard-wiring). The outlet must be
accessible at all times after installation
to disconnect the dishwasher.
, 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. Installing the
dishwasher in a tight space may crimp
the power cord or put pressure on the
plug which could cause overheating.

IMPORTANT SAFETY INSTRUCTIONS
Use
To reduce the risk of injury, do not
allow children to play in, on or near
the dishwasher.
Only use the dishwasher if all
panels are properly in place.
Do not tamper
with the controls.
Do not damage, sit or stand on the
door or baskets of the dishwasher.
Close the door when not in use.
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.
Only use detergents and rinse aids
recommended for residential
dishwashers. Keep all detergents and
rinse aids out of the reach of children.
Do not inhale or swallow
detergents. Dishwasher detergents
contain irritant and corrosive
ingredients. They can cause burning in
the mouth and throat if swallowed, or
inhibit breathing. Consult a doctor
immediately if detergent has been
swallowed or inhaled.
Do not drink water from the
dishwasher! Harmful residues
could be present.
Do not fill the rinse aid reservoir or
salt container with detergent. It will
destroy the rinse aid compartment and
water softener.
If the power cord is damaged it
must only be replaced by a Miele
Service technician with a genuine Miele
power cord.
Be sure that all items placed in the
dishwasher are "dishwasher safe".
For items not labeled, check the
manufacturer’s recommendations.
When loading tableware, place
sharp items away from the door to
prevent damage to the seal. Load
sharp items pointing downwards to
prevent injuries.

Energy saving washing
This dishwasher is exceptionally
economical in the use of water and
electricity. For best results follow these
tips:
For lowest energy consumption and
^
the gentlest washing of china and
crystal, connect the dishwasher to a
cold water source.
For fastest possible wash times, yet
^
higher energy consumption, connect
the dishwasher to a hot water source.
Make full use of the baskets without
^
overloading for the most economical
washing.
^ Use the correct amount of detergent
and rinse aid.
Caring for the environment
^ When using powder or gel detergent,
reduce the amount to
normal amount when washing a small
load.
^ Choose a program that best suits the
degree of soiling and the type of
dishes being washed.

Before using for the first time
Water softener
Every dishwasher is tested before
leaving the factory. Any water
remaining in the machine is from the
final factory test and does not
indicate that the machine has been
used.
To achieve good cleaning results, the
dishwasher needs soft water. Hard
water results in calcium deposits on
dishware and in the dishwasher.
If your tap water hardness is above 4°d
(4 gr/gal [US]), the water should be
softened. This takes place
automatically in the unit’s integrated
water softener.
The water softener is set automatically
to the local water hardness.
The water softener is designed for a
water hardness of up to 70 °d.
If the hardness of your local supply
is constantly lower than 4 °d (4 gr/gal
[US]), you do not need to add water
softener salt. The salt indicator
turns off automatically.
Checking the water hardness
Once the dishwasher has been
installed and connected, run the
"Rinse + Hold" program. After the
program has finished, the water
hardness measured by the sensor can
be displayed.
This value is displayed in °d and may
fluctuate depending on the water
quality.
Turn the dishwasher off s.
^
Press the "Start/Stop" button and at
^
the same time turn the dishwasher on
s. Hold the "Start/Stop" button until
the "Start/Stop" indicator comes on.
If it does not come on, start over.
^ Press the "Delay Start" button 6 times.
The "Delay Start" indicator flashes
6 times in intervals.
The measured water hardness is
displayed in °d and is shown in the time
display as the number after the p.
^
Turn the dishwasher off s.
11
Before using for the first time
Filling the salt container
Inadvertently filling the salt
,
container with dishwashing
detergent will damage the water
softener.
Only use water softener salt
,
specially formulated for
dishwashers. Other salts may
contain insoluble additives which
can impair the water softener.
Remove the lower basket and
^
unscrew the salt container lid.
When opening the salt container,
water will run out. Open the reservoir
only to refill salt.
Important: The salt container must
be filled with 2 quarts (2 l) of water
before adding salt for the first
time. Water does not have to be
added with subsequent refills.
Place the provided funnel over the
^
salt container. Carefully fill with salt.
The salt container holds approx.
4.5 lbs (2 kg) of salt. As it is filled,
water will run out.
^ Clean any excess salt from the
threads of the reservoir opening.
Screw the lid on firmly.
^ If the dishwasher will not be used
immediately, run the "Short" program.
This will remove any traces of salt
from inside the wash cabinet.
12
Salt indicator
^ When the "Salt" indicator comes on,
refill the salt after the program is
finished.
After the reservoir has been filled, the
water softener is automatically
reactivated the next time the
dishwasher is started. The "Salt"
indicator will be lit during this process.
Before using for the first time

Before using for the first time
Rinse aid
Rinse aid helps to prevent spotting on
dishes and glassware.
The rinse aid is filled in the reservoir

automatically dosed.
Filling the rinse aid reservoir with
,
detergent will damage the reservoir.
Only pour rinse aid formulated for
residential dishwashers into the
reservoir.
When using "2 in 1" detergents rinse
aid is not needed.
Adding rinse aid
^
Press the button in the direction of
the arrow until the flap springs open.

until it its visible on the surface of the
screen.
The rinse aid reservoir holds approx.
3.7 oz (110 ml).
^ Press on the flap until you hear it
click shut. Failure to close it all the
way allows water to enter the
reservoir during the wash program.
^
Clean any spilled rinse aid. The flap
will remain closed during normal
operation.
14
Before using for the first time
Rinse aid indicator
When the rinse aid indicator first comes
on, there will be enough rinse aid left
for 2 - 3 washes.
^ The rinse aid indicator on the control
panel will light when the rinse aid
reservoir needs refilling.
If the "2 in 1" function is selected, the
rinse aid indicator will not light, see
"Additional functions - Detergent
settings".
Adjusting the dosage
The dosage selector is preset to 3. This
dispenses approximately 3 ml of rinse
aid per program. It can be adjusted

Loading the dishwasher
Do not wash items soiled with
,
ash, sand, wax, grease or paint in
the dishwasher.
Ash and sand do not dissolve and
will be distributed throughout the
inside of the dishwasher.
Wax, grease and paint will cause
permanent discoloration and
damage to the dishwasher.
Scrape food from dishes before
^
placing them in the dishwasher,
rinsing is not necessary.
^ Some foods contain natural dyes,
e.g. carrots or tomatoes. Plastic items
may discolor permanently if they
come in contact with food dyes.
^ All items can be placed anywhere in
the baskets.
^ Load dishes so that water can reach
all surfaces. Do not place dishes or
cutlery inside other pieces.
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.
Place very small items in the cutlery
^
tray or basket so they do not fall to
the bottom of the wash cabinet.
Food residue and spilled liquids
^
should be cleaned from the sides of
the dishwasher door. These are
outside of the wash cabinet and are
not cleaned by water from the spray
arms.
^
Make sure that all items are securely
positioned.
^
Hollow items such as cups and
glasses should be placed upside
down in the baskets.
^
To ensure good water coverage,
tall, narrow and hollow items,
i.e. vases or champagne glasses,
should be placed in the center of the
basket rather than in the corners.
^
Concave based items such as mugs
or bowls, should be placed at an
angle so that water does not pool.
