Function of the glassware washer

This Miele dishwasher is designed for
cleaning and rinsing laboratory
glassware which is suitable for machine
reprocessing. Always follow the
labware manufacturer's instructions.

Examples of application areas:

laboratory glassware used in

–

research and development,

laboratory glassware used in areas

–

of analysis and specimen taking,

laboratory glassware used in

–

micro-biology and biotechnology.

The type of laboratory glassware which
can be reprocessed ranges from Petri
dishes to centrifugal test tubes.

Reprocessing glassware by machine
achieves reproducible results and
should be used in preference to
processing them by hand.

The cleaning program as well as the
agents used must be chosen according
to the type of soiling and load being
processed.
The agents used in the machine for
reprocessing should be selected
according to the level of cleaning
required as well as the method the
product will be used.

The use of a suitable carrier (mobile
unit, module, insert etc.) is important to
ensure adequate cleaning. Examples
are given in the section "Areas of
application".

The dishwasher is programmed to carry
out the final rinse with mains water or
with processed water of a quality to suit
the application (e.g. distilled, purified,
de-ionized or demineralized water). The
water quality is important for
applications requiring analytically clean
laboratory glassware.

programmed. The water needs to be
softened to avoid calcium deposits on
the items being cleaned and in the
machine itself.
If the water supply is harder or softer
than the factory setting (including
below 4 gr/gal or 70 ppm), the setting
will need to be changed. See "Setting
the water softener".

In order to function properly, the

–

water softener requires a supply of
reactivation salt.

– The cleaner must be correctly

programmed to match the hardness
of the tap water supply.

– Your local water authority can

provide information about the
hardness of the tap water in your
area.

If the water hardness is known to
fluctuate, always program for the
highest value.

The built-in water softener can be
programmed at settings from
1 - 60 gr/gal or 20 - 1080 ppm.

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

Please note the water hardness in the
space provided here:

Filling the salt reservoir

Only special, coarse-grained
reactivation salt* should be used in
this lab washer.

*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
Miele Technical Service.

The salt reservoir holds approximately

2.5 kg salt.

Inadvertently filling the salt

,

reservoir with detergent will damage
the water softener.
Before filling the reservoir, make
sure that you are using reactivation
salt.

Remove the bottom basket from the

^

machine.

^

Before filling the salt reservoir for the
first time fill the reservoir with
approximately 2.5 liters of water, so
that the salt can dissolve properly.
Once the lab washer has been
operated, there will always be
enough water in the reservoir.

^

Place the funnel provided in place.

^

Carefully fill the reservoir with the
reactivation salt.

15

Water softener

Wipe any residual salt off the screw

^

threads and seal of the reservoir.

^ Screw the cap on securely.

^ Immediately after this step, start the

"Rinse" program, to remove any
traces of salt from the inside of the
lab washer.

Note: There may be a delay of a few
minutes before the "Rinse" program
starts due to the reactivation of the
water softener.

Salt indicator

When the salt reservoir is empty, the
"Recharge Softener" indicator b lights
to remind you to fill the reservoir.

Reactivation takes place automatically
as needed during a program. The
"Recharging" indicator a lights while
this is occurring.

16

Areas of application

Depending on the type of labware you
wish to clean, the lab washer can be
used with an upper basket, lower
basket, or injector wagon, as well as an
assortment of inserts and special
baskets to suit your needs.

Baskets and inserts should be
properly selected to match the
application desired.

Before every program start, conduct
the following visual inspection:

– Is the labware properly loaded and

secured in the lab washer?

– Are the hollow vessels properly

loaded so that all cavities and
channels will be flushed clean?

– Are the spray arms clean, and can

they rotate freely?

– Is the filter combination free of

coarse debris (clean if necessary)?

After every program completion,
conduct the following visual
inspection:

Inspect the labware for cleanliness.

–

Has any hollowware been dislodged

–

from its proper position on the
nozzles?

Any items that were dislodged

,

from the adapters during a program
cycle must be washed again.

Are the cavities and channels in any

–

hollow vessels cleaned through?

– Are the nozzles and connections

firmly attached to the
baskets/inserts?

–

Is the basket adapter properly
connected to the water supply for the
spray arms and nozzles?

–

Are the chemical dispensers filled?

17

Areas of application

Loading the machine

Disposable items must not be
processed in the machine.

Always load items in a way that all

–

surfaces are exposed. This ensures
that the items will be properly
cleaned.

Do not nest any items inside other

–

items. Keep each item separate.

Hollow vessels must be arranged for

–

complete inside exposure to the
cleaning water.

– Prior to loading the machine or

connecting to the machine ensure
that vessels with long, narrow
cavities they can be completely
flushed.

– Hollow vessels should be inverted

and placed in suitable baskets and
inserts so that water will have
unrestricted access and exit.

–

Deep-based items should be
arranged at an angle, so that water
can run off easily.

–

Tall, narrow pieces should be placed
in the center of the basket for best
water coverage.

–

Secure light loads with netting and
place small items in a mesh
tray/basket so that they do not
obstruct the spray arms.

–

Baskets and inserts with an adapter
must be properly connected.

–

The spray arms must not be blocked
by items that are too tall or hang
through the baskets.

To avoid corrosion, only load

–

stainless steel instruments in good
condition.

Do not use this machine to wash

–

nickel-plated items or discolored
(oxidized) aluminum items.

Do not load plastics unless they are

–

heat-resistant.

Effects of Processing Chemicals

General information

Effects Action

Damage to elastomer (seals and hoses)
or plastic components of the lab
washer may cause the materials to
swell, shrink, harden or become brittle,
possibly causing cracks to form in the
materials. This will impair their function,
which will generally lead to leaks.

Strong foaming during the program
prevents proper cleaning and rinsing of
the load. Foam escaping from the wash
compartment can result in damage to
the lab washer.
If foaming occurs, the cleaning process
is not standardized and not validated.

Stainless steel corrosion in the wash
compartment and/or accessories may
appear in various ways:

– rust formation (red spots / stains),
–

black spots / stains,

–

white spots / stains (smooth surface
is slightly corroded).

Corrosion that forms holes can result in
leaks in the lab washer. Depending on
the application, the corrosion may
impair the cleaning and rinsing results
(laboratory analysis) or cause corrosion
of the load (stainless steel).

Find and correct the causes of the

–

damage.

See "Connected processing
chemicals", "Soiling" and "Reactions
between processing chemicals and
soils" for more information.

Find and correct the cause of the

Effects of Processing Chemicals

Connected processing chemicals

Effects Action

The ingredients of the processing
chemicals have a considerable effect
on the durability and functionality (feed
performance) of the metering systems.
The metering systems (feed hoses and
pump) are designed for a specific type
of processing chemicals.

General categories:

alkaline to neutral pH products,

–

acid to neutral pH products,

–

The processing chemicals can damage
the elastomer and plastic components
of the lab washer and its accessories.

The following processing chemicals
can result in excessive foaming:

– tenside cleaners containing

detergent and rinse aid.
The foaming can occur:
–

in the program block in which the

processing chemical is added,
–

in the subsequent program block

due to carry-over,
–

in the case of rinsing agents, in the

subsequent program due to

carry-over.

Use only those processing chemicals

–

recommended by Miele.
Consult a Miele Applications
Specialist.

Perform regular visual inspections of

–

the metering system.
Regularly check the feed

–

performance of the metering system.

– Use only those processing chemicals

recommended by Miele.
Consult a Miele Applications
Specialist.

– Perform regular visual inspections of

all visible elastomer and plastic
components.

– The process parameters of the wash

program, e.g. metering temperature,
metering concentration, etc. must be
set so that the overall process
creates little or no foam.

–

Observe the instructions of the
manufacturer of the processing
chemicals.

23

Effects of Processing Chemicals

Connected processing chemicals

Effects Action

Antifoaming agents, particularly
silicone-based antifoaming agents, can
cause the following:

deposits in the wash compartment,

–

deposits on the wash load,

–

damage to the elastomer and plastic

–

components of the lab washer,

attack certain plastics (e.g.

–

polycarbonates, plexiglass, etc.) in

the wash load.

Use antifoaming agents only in

–

exceptional cases or when they are
absolutely necessary for the process.

Periodic cleaning of the wash

–

compartment and accessories
without a load and without an
antifoaming agent using the
"Regular" or "Extended" program.

Consult a Miele Applications Specialist.

24

Effects of Processing Chemicals

Soiling

Effects Action

The following substances can damage
the elastomer components (hoses and
seals) and, in some cases, the plastic
components of the lab washer:

oils, waxes, aromatic and

–

unsaturated hydrocarbons,

softeners,

–

cosmetics, hygiene and skin care

–

products such as creams (analysis

and filling sections).

The following substances can cause
excessive foaming during washing and
rinsing:

– agents such as disinfection agents,

dish detergents, etc.
– reagents for analysis, e.g. for

microtitration plates,
– cosmetics, hygiene and skin care

products such as creams (analysis

and filling sections).
–

foaming substances in general, for

instance tensides.

Retrofit the lab washer with more

–

grease-resistant elastomers.
Depending on usage, periodically

–

wipe the lower door seal with a
lint-free cloth or sponge.
Clean the wash compartment and
accessories without a load using the
"Regular" or "Extended" program.

To process the load, use the

–

program "Regular" or "Extended" and
place additional powder cleaning
agent on the door.

– Thoroughly rinse the items in water

beforehand.

– Select the "Extended" program

(pre-wash with cold or hot water).

– Taking the specific application into

account, add an antifoaming agent,
one without silicone oils if possible.

The following substances can cause
corrosion to the stainless steel in the
wash compartment and accessories:

–

hydrochloric acid,
–

other substances that contain

chloride, e.g. sodium chloride, etc.
–

concentrated sulphuric acid,
–

chromic acid,
–

iron particles.

–

First rinse the load with a sufficient
quantity of water.

–

Let the load drip dry before putting it
on the carts, baskets and inserts and
placing in the lab washer.

25

Effects of Processing Chemicals

Reactions between processing chemicals and soils

Effects Action

Natural oils and greases can be
saponified with alkaline processing
chemicals. This may cause a lot of
foaming.

In combination with alkaline processing
chemicals, loads with soiling that
contains proteins, e.g. blood, can
cause excessive foaming.

In combination with very acidic or
alkaline processing chemicals, base
metals such as aluminum, magnesium
and zinc can release hydrogen
(detonating gas).

Use the "Regular" or "Extended"

–

program.
Depending on the application add an

–

antifoaming agent that does not
contain silicone oils.

Select the "Extended" program

–

(pre-wash with cold water) where a
cold water connection is available.

Observe the instructions of the

–

manufacturer of the processing
chemicals.

26

Only use cleaning agents
formulated for this machine. Do not
use detergents formulated for
domestic dishwashers.
Observe the instructions of the
manufacturer of the processing
chemicals.

Dispensing neutralizing or
rinsing agent

A duo-dispensing system for liquid
agents which can be used to dispense
either neutralizing agent or rinsing
agent, is located in the door.

A change of agent, e.g. from
neutralizer to rinsing aid, requires
re-programming by Miele Service.

The machine is set to dispense
neutralizer as factory default.

The duo-dispensing system consists of
two reservoirs and two dosage
selectors.

Dispensing chemical agents

Neutralizing agent

Neutralizing agent (pH-level: acidic)
neutralizes residues of alkaline cleaning
agents on the surface of instruments
and utensils.

The neutralizer is automatically
dispensed in the program stage Rinse
1 following the main wash of a program.
The dispensing system reservoir must
be filled and the dishwasher
programmed to dispense neutralizing
agent.

Rinsing agent

Rinse aid is necessary to ensure water
does not cling and leave marks on
items, and to help items dry faster after
they have been washed. The
dispensing system reservoir must be
filled and the dishwasher programmed
to dispense rinsing agent.

The components of the rinsing agent
remain on the surface of items after
they have dried. Depending on what
the utensils are being used for, it is
therefore important to check that rinsing
agent may be used.

The components of the rinsing agent
remain on the surface of items after
they have dried. Depending on what
the utensils are being used for, it is
therefore important to check that rinsing
agent may be used.

27

Dispensing chemical agents

Filling the reservoirs

Important: Both reservoirs must

,

always be filled with the same liquid
agent.

Only fill the duo-dispensing

,

system with neutralizing agent or
rinsing agent formulated for
dishwashers. Do not fill with
cleaning agent. This would damage
the reservoirs.

Open the door fully.

^

Add liquid agent until the level

^

indicator is dark (see arrow on
illustration). Use a funnel if
necessary.

Each reservoir holds approx. 6 oz.
(180 ml).

^ Screw the caps back on.

^

Unscrew the caps.

28

^ Mop up any spilt liquid agent. This

prevents over-foaming occurring
during the next program.

Dispensing chemical agents

Adjusting dosage

The dosage adjuster in the opening has
settings adjustable from 1 to 6 (1- 6 ml).
It is preset to "5" (10 ml) as the
recommended dosage for neutralizer.

^ Use a flat headed screw driver to turn

the dial to the correct setting.

If spots appear on items:

Add neutralizing agent indicator

^ The container for neutralizing agent

should be refilled when the indicator
lights up.

Add rinsing agent indicator

^

When using neutralizing agent select
a lower dosage.

^

When using rinsing agent select a
higher dosage.

If clouding or smearing appears on
items:

^

When using neutralizing agent select
a higher dosage.

^

When using rinsing agent select a
lower dosage.

^

Add rinsing agent to the rinsing
agent reservoirs when the indicator
lights up.

29

Dispensing chemical agents

Adding detergent

Use only cleaning agents

,

formulated for this machine. Do not
use detergents formulated for
household dishwashers.

Avoid inhaling cleaning agents

,

in powder form. If processing
chemicals are ingested, they can
cause chemical burns in the mouth
and throat or suffocation.

Before starting the program, load the
powdered detergent into the
compartment (except for the programs
"Rinse" and "Drain").

Dosage: To achieve a detergent
concentration of approximately 3 g/l,
use 30 g of detergent.

Always follow the detergent
manufacturer's recommendations for
dosage concentration.

The flap is always open at the end of a
program.

^ Add powder cleaning agent to the

The machine must be connected to

^

the water supply in accordance with
local and national regulations.

The washer is constructed so it may

^

be connected to a supply without an
extra non-return valve, unless
required by code.

An acceptable water pressure (flow

^

rate) is 10 - 147 psi. However, the
recommended pressure is
25 - 60 psi.
If the water pressure is below 30 psi,
the fill time will take longer.
If the "Fill/Drain" fault code "F..E" is
displayed, contact the Technical Ser­vice Department.

^ The machine is supplied to be

connected to a standard cold (coded
blue) or hot (coded red) water supply
to a maximum temperature of 158 °F
(70 °C).
Connect the water intake hoses to the
cold and hot water faucets.
If no hot water supply is available, the
hot water intake hose with the red
marking needs to be connected to
cold water by a y-adapter.
