Caring for the environment

Disposal of the packaging

The packaging protects the commercial
dishwasher from damage during
shipping. They have been selected for
environmental friendliness and can be
recycled.

The packaging comprises the following
materials:

Exterior packaging:

Corrugated cardboard made of up to

–

100% recycled material,
or: polyethylene (PE) stretch wrap
film

– Polypropylene (PP) tightening straps

Interior packaging:

– Expanding polystyrene (EPS) without

chlorine or fluorine

– Floor, lid frame and support strips

made of untreated natural wood
harvested from forest stewardship
forests

–

Polyethylene (PE) protective film

Returning the packaging to the
materials cycle saves raw materials and
reduces waste. Your local community
waste collection / recycling centre will
tell you where the nearest return depot
is located.

Disposing of your old
appliance

Old electric and electronic equipment
still contains useful materials that can
be recovered. However, it may also
contain harmful substances that were
necessary for their function and safe
use. Improperly disposing of these
items in your household waste can be
harmful to your health and the
environment. This is why it is important
NEVER to dispose of your old
appliance in your regular household
waste.

Instead, use your local community
waste collection and recycling centre
for electric and electronic appliances.

If the appliance is being stored prior to
disposal, please make sure it is
child-proof.

All the plastics in the appliance are
marked with standard international
symbols. This allows the separation of
different plastic waste materials for
recycling.

16

Energy saving washing

This commercial dishwasher is a water
and energy saving appliance.
For best results follow these tips:

You may connect the commercial

^

dishwasher to a hot water line. This is
particularly suitable with
energy-saving water heating sources
such as solar energy systems.
If the hot water system is electrically
heated and if loads comprise
primarily glassware we recommend
connecting the appliance to the cold
water line.

^ Make full use of the baskets' capacity

without overloading. This ensures the
most economical washing.

^ Choose a program that best suits the

degree of soiling and the type of
dishes being washed.

Caring for the environment

When using powder or liquid

^

detergent, you can reduce the
amount by
the baskets are only half full.

1

/3of the normal dosage if

^ Use the Normal program for energy

saving dishwashing.
From the aspect of combined energy
and water consumption, this program
is the most efficient for washing
normally soiled dishes.

The commercial dishwasher must be
correctly programmed to match the
hardness of your water.

–

Your local waterworks will be able to
advise you of the water hardness in
your area.

It is useful to know your water hardness
so that you can provide the service
technician with this information in the
event of any service calls.

Please note your water hardness below:

These basic settings are saved after
the first full program cycle is
completed.

The Welcome screen is no longer
displayed after the first full program
cycle is completed.

–

Where the water hardness fluctuates
(e.g. 17 - 25 gr/gal), always use the
higher value (in this example
25 gr/gal).

20

Before using the commercial
dishwasher for the first time
you will need:

approx. 1 kg reactivation salt,

–

approx. 110 ml rinse aid,

–

for detergent see "Operating the

–

commercial dishwasher". For
available process chemicals from
Miele contact Miele Professional.

Every commercial dishwasher is
tested before leaving the factory.
There may be residual water in the
machine from this testing. This is not
an indication that it has been
previously used.

Filling the salt reservoir

To achieve good cleaning results, the
commercial dishwasher needs soft
water (water that is low in minerals).
Hard water results in white deposits on
dishware and in the dishwasher.
Therefore, tap water with a hardness of
4 gr/gal (70 ppm CaCO3) or more must
be softened. This takes place
automatically in the integrated water
softener. The water softener requires
reactivation salt. The water softener is
suitable for a water hardness of up to
36 gr/gal (650 ppm CaCO3).

Before using for the first time

If the hardness of your water is
always below 4 gr/gal (= 70 ppm
CaCO3), you do not need any salt.
However, you must still program
your dishwater for your water
hardness.

Do not fill the salt reservoir with

,

dishwashing detergent (even liquid
detergent). Dishwashing detergent
will damage the water softener.

Use only special, coarse-grained

,

reactivation salt. Other types of salt
may contain insoluble components
which can damage the water
softener.

See "Settings menu - Water hardness"
for setting the water softener.

21

Before using for the first time

Only open the door half way when

^

adding salt to avoid spilling it.

^ Press the button on the top of the salt

reservoir in the direction of the arrow.
The cover will pop open.

Do not fill water into the salt
reservoir!

^ Only add just enough salt to fill the

reservoir. Depending on the type of
salt, the reservoir will hold up to
approx. 1 kg.

^

Open the funnel.

22

Never fill with more than 1 kg of salt.

Displaced water may run out as the
reservoir is being filled.

^

Clean any excess salt from the filling
area and close the cover of the
reservoir.

^

Immediately run the "Pre-wash"
program without a load in order to
remove any traces of brine from the
cabinet.

Refill salt indicator

Refill the salt reservoir as soon as the

^

Add salt message is displayed (if

F

it appears during a program, wait
until the end of the program).

Press the centre button to confirm.

^

The Refill salt indicator goes out.

If a sufficiently high concentration of
salt has not yet formed, Refill salt may
continue to be displayed after adding
the salt.
In this case, confirm again with the
centre button.

The Refill salt message is turned off if
you have programmed the commercial
dishwasher to a water hardness below
4 gr/gal (= 70 ppm CaCO3).

,

Immediately after each refill run
the Pre-wash or Short program
without a load in order to remove
any traces of brine from the cabinet.

Before using for the first time

23

Before using for the first time

Rinse aid

Rinse aid helps to prevent spotting on
dishes and glassware and speeds up
the drying process.
The rinse aid is filled into the reservoir
and the set amount will be
automatically dispensed. For available
process chemicals from Miele contact
Miele Professional.

Use rinse aid only. Never fill the

,

rinse aid reservoir with regular
dishwashing detergent or cleaning
agent. This will damage the rinse aid
reservoir.

Adding rinse aid

^ Press the button on top of the rinse

aid reservoir in the direction of the
arrow. The cover will pop open.

24

Pour rinse aid into the reservoir until it

^

is visible in the opening.

The rinse aid reservoir holds
approximately 110 ml.

^ Close the cover until you hear it click

shut, otherwise water might enter the
reservoir during the wash program.

Before using for the first time

Rinse aid indicator

When the ( Add rinse aid message
appears, the reservoir only contains
enough rinse aid for2-3wash
programs.

Add rinse aid soon.

^

Press the centre button to confirm.

^

The "Refill rinse aid" message goes out.

menu - Rinse aid").

25

Loading the commercial dishwasher

Tips:

Remove coarse food residues from the
dishware.

There is no need to rinse items under
running water!

Do not wash items soiled with

,

ash, sand, wax, grease or paint in
the commercial dishwasher.
These materials damage the
commercial dishwasher.

All items can be placed anywhere in
the baskets. However, note the
following:

– Do not place dishes or cutlery inside

other pieces. They will cover each
other.

– Load dishes so that water can reach

all the surfaces. This ensures that the
items will be properly cleaned!

– Make sure that all items are securely

positioned.

Concave items such as mugs or

–

bowls should be placed at an angle
so that the water can run off.

Ensure that the spray arms are not

–

blocked by items that are too tall or
that hang through the baskets.
Check clearance by manually
rotating the spray arms.

Place very small items such as lids in

–

the cutlery tray or basket (depending
on the model) so they do not fall to
the bottom of the wash cabinet.

Some foods, e.g. carrots, tomatoes
and ketchup, may contain natural
dyes. Plastic items may discolour
permanently if they come in contact
with food dyes. This discolouration
does not affect the stability of the
plastic items.

–

Hollow items such as cups, glasses
and pots should be placed upside
down in the baskets.

–

Place tall, narrow, hollow items, e.g.
champagne glasses, in the center of
the basket rather than in the corners.
This ensures good water coverage.

26

Loading the commercial dishwasher

Items not recommended for
dishwashing:

Wooden cutlery and dishes or items

–

with wooden parts, as they may
discolour and fade. In addition, the
glue used in these items is not
dishwasher-proof. This may result in
wooden handles coming loose.

Hand-crafted items, antiques,

–

valuable vases and decorative
glassware are also not
dishwasher-proof.

Plastic items which are not heat

–

resistant may become deformed.

– Copper, brass, tin and aluminium

items may discolour or become dull.

– Colours painted over a glaze may

fade after a number of washes.

– Fine glassware and crystal may

become cloudy over time.

We recommend:

When purchasing dishes and cutlery,

–

make sure they are dishwasher-safe.

Drinking glasses may become

–

cloudy over time. Fine glassware
should only be washed at low
temperatures (see "Program guide")
This reduces the risk of clouding.

Attention!

Silverware that was previously cleaned

with a silver polish may still be damp
or spotted at the end of a program
since the water does not run off
smoothly. Dry with a soft cloth.

Silver may discolour if it comes into
contact with foods that contain sulphur.
These include egg yolk, onions,
mayonnaise, mustard, legumes, fish,
fish brine and marinades.

,

Aluminum components (e.g.
grease filters) must not be washed
with caustic alkaline commercial or
industrial cleaning agents in the
commercial dishwasher. These may
damage the material. In extreme
cases they can cause a severe
explosive chemical reaction (such
as explosive hydrogen gas
reactions).

Cleaning and care

Check the overall condition of your
commercial dishwasher regularly
(approx. every4-6months). This
will help to prevent problems.

The outer surfaces of the

,

commercial dishwasher are
susceptible to scratching.
Contact with unsuitable cleaning
agents can alter or discolour the
outer surfaces.

Cleaning the door and the door
seal

Wipe the door seals regularly with a

^

damp cloth to remove food deposits.

Wipe food and drink residues off the

^

commercial dishwasher door.
These surfaces are outside the wash
cabinet and are not reached by water
from the spray arms.

Cleaning the front of the
commercial dishwasher

Cleaning the wash cabinet

The wash cabinet is largely
self-cleaning, provided that the correct
amount of detergent is always used.

If, however, there are limescale or
grease deposits in the cabinet, these
can be removed with a special
dishwasher cleaner (available from
Miele Service).

Washing at low temperatures can allow
germs and odours to build up inside
the appliance. To prevent this, run an
intensive program with detergent after
approx. 20 program cycles with low
temperatures.

Remove any soiling immediately.

,

Otherwise it might become
impossible to remove and could
cause an alteration or discolouration
of the surfaces.

^ Clean the front of the appliance with

a clean sponge, dishwashing liquid
and warm water. Then wipe dry with
a soft cloth.
You can also use a clean, damp
microfibre cloth without detergent.

^

For surface disinfection use low or
intermediate-level disinfectants only.

44

To avoid damage to the outer
surface, do not use:

cleaning agents containing soda,

–

ammonia, acid or chloride,

limescale removers,

–

abrasive cleaners such as scouring

–

powder, scouring liquid or pumice
stones,

cleaners containing solvents,

–

stainless steel cleaners,

–

dishwasher cleaner,

–

oven sprays,

–

– glass cleaners,

– rough scouring sponges or brushes

such as pot scrubbers,

– magic erasers,

– sharp metal scrapers,

Cleaning and care

Checking the filters in the
wash cabinet

The filter combination in the base of the
wash cabinet captures large dirt
particles from the wash water. This
prevents them from reaching the
circulation system and re-entering the
cabinet through the spray arms.

This commercial dishwasher

,

must not be used without all the
filters in place!

Collection of coarse particles may
cause the filters to clog over time. The
dirtier the dishware the sooner the
filters need cleaning.

every 50 program cycles.

You can turn off the filter check or set
the frequency to 30 to 60 program
cycles (see Settings menu - Filter
check).

protect the water inlet valve. The screen
must be cleaned when dirty, otherwise
insufficient water will flow into the wash
cabinet.

The plastic housing of the water

,

connection contains an electric
valve. The housing must not be
immersed in water.

Maintenance

Recommendation

If the water supply contains a large
amount of insoluble substances, we
recommend fitting a large-area filter
between the tap and the water inlet
hose.
This filter is available from Miele Ser­vice.

To clean the screen:

^ Disconnect the commercial

dishwasher from the electric power
supply. Always switch the appliance
off before unplugging it.

^

Close the water tap.

^

Unscrew the water inlet valve.

Take the seal ring out of the screw

^

connection.

^ Use needlenose pliers to pull out the

screen, then clean it.

^ When removing the screen, take care

not to pull out or displace the flow
regulator behind it.

^ Replace the screen and seal. Make

sure they are positioned correctly.

^

Reconnect the water inlet valve to the
tap. Make sure not to cross-thread
the connection.

^

Turn the tap back on.
If the connection leaks it might be too
loose or cross-threaded.
Unscrew and reconnect the water
inlet valve correctly.

equipped with a 14/3 AWG cord for
connection to a standard AC 120 V,
60 Hz power outlet with a NEMA 5-15P
plug.

If available, the dishwasher may be
connected to a 120/208-240V, 60Hz,
power supply. This will increase the
power to the heating elements and
shorten the time of selected wash
cycle.

120V 208-240V

Rated Load (kW) 1.5 3.9 - 4.2

Fuse Rating 15A 30A

To connect the machine to a

GROUNDING INSTRUCTIONS This
appliance must be grounded. In the
event of malfunction or breakdown,
grounding will reduce the risk of
electric shock by providing a path of
least resistance for electric current. This
appliance is equipped with a cord
having an equipment-grounding
conductor and a grounding plug. The
plug must be plugged into an
appropriate outlet that is properly
installed and grounded in accordance
with all local codes and ordinances.

WARNING – Improper connection of
the equipment-grounding conductor
can result in the risk of electric shock.
Check with an electrician if in doubt of
the appliance’s grounding. Do not
modify the plug provided with the
appliance: if it will not fit the outlet, have
a proper outlet installed by a qualified
electrician.

The wires in the cord are colored in
accordance with the following code:

green = ground

white = neutral

black = live 1

red = live 2

WARNING
THIS APPLIANCE MUST BE
GROUNDED

Plumbing

The Miele waterproof system

Providing the dishwasher was installed
correctly by a qualified technician, the
waterproof system will protect you from
water damage throughout the lifetime of
the machine.

Water intake

The water in the commercial

,

dishwasher is NOT safe to drink!

The commercial dishwasher must be

–

connected to the water supply in
accordance with local regulations.

– The water supply must at least meet

the standards for drinking water.
A high iron content can leave a rustfilm
on dishware and the commercial
dishwasher itself.
When the chloride content in the
domestic water supply is above
100 mg/l, the risk of corrosion damage
to dishware is greatly increased.

–

The commercial dishwasher can heat
its own water to the temperature
required by the wash program. This
allows for connection of the mashine
to either a hot (max. 60 °C) or cold
water source.
For lowest energy consuption and
fastest possible wash times connect
the commercial dishwasher to a hot
water source. All programs use hot
water in the rinse cycles.

The commercial dishwasher is

–

equipped with a safety system for the
protection of drinking water and may
be connected to the water supply
without a non-return valve, if national
regulations permit.

The water pressure (flow pressure at

–

the water connection) must be
between 30 und 1000 kPa (4.4 and
145 psi).
If the water pressure is lower, the
message
(see Frequently asked questions).
If the water pressure is higher, a
pressure reducer must be installed.

– A water shut-off valve with a

thread is required for connection to
the water supply. The valve should
be easily accessible, because the
water supply must be turned off
when not in use.

– The inlet hose is 1.7m long, with a

2 cm female hose thread. A 1.5 m
extension hose is available (flexible
metal hose certified for a pressure of
14000 kPa/ 2031 psi). The dirt
screen and the flow regulator in the
threaded water connection must not
be removed.

Water intake is displayed

–

In certain regions (e.g. mountain
regions) the water composition may
cause precipitates to form, requiring
the use of softened water for the
commercial dishwasher.

68

Plumbing

To prevent damage to the

,

commercial dishwasher, make sure
all air has been bled from the supply
line.

! The inlet hose must not be

shortened or damaged in any way
because it contains electrical wires
(see illustration).

69

Plumbing

Water drainage

The drain is equipped with a

–

non-return valve which prevents
waste water from flowing back into
the commercial dishwasher through
the drain hose.

The commercial dishwasher drain

–

hose should be connected to a
separate drain for the commercial
dishwasher only.
If no separate drain is available, we
recommend connecting it to a
dual-chamber siphon.

– The commercial dishwasher is

equipped with a 1.5 m flexible drain
hose with an internal diameter of
22 mm.
Connecting clamps are provided
with the commercial dishwasher.

– An additional hose and adapter can

be used to extend the drain hose.
The drain hose length must not
exceed 4 m and the pumping height
must not exceed 1 m!

Venting the drainage system

The drain must be vented if the
connection to the building' s drainage
system is lower than the roller guides
for the lower basket in the door.
Otherwise the water inside the
commercial dishwasher may siphon out
during the wash program.

For venting:

Open the commercial dishwasher

^

door completely.

–

The drainage system must be able to
accommodate a minimum drainage
flow of 16 l/min.

–

The drain hose must not be
shortened!

,

Make sure the hose is not

kinked, squashed or pulled too tight.

70

^

Pull the lower spray arm up to
remove.
