The following points should be
observed to assist in maintaining
quality standards, for critical lab
glassware and to avoid damage to
the loads being cleaned.
If the cleaning result is subject to
particularly stringent requirements
(e.g. chemical analysis, specialized
process), a regular quality control test
should be carried out by the user to
ensure that required standards of
cleanliness are being achieved.
Be aware of the high risk when
interrupting a wash cycle and
opening the door, if toxic or chemical
substances could be present in the
wash water. Always check the seal of
the door and the function of the steam
condenser.
Use only Miele approved cleaning
agents with this machine. Use of
unsuitable cleaning agents could
adversely affect the components of the
machine. Damages resulting from using
unsuitable cleaning agents are not
covered by the warranty.
Pre-treating (e.g. with cleaning
agents) certain soiling, and
cleaning agents with a chemical
interaction can cause foam. For
pre-treatment and/or cleaning only use
low-sudsing detergents and
disinfecting agents which have been
approved by Miele. Suds can have an
adverse effect on the cleaning process.
When a chemical additive is
recommended, the manufacturer of
the machine takes no responsibility for
the effect of the chemical on the items
being cleaned. Please be aware that
changes in formulation, storage
conditions, concentration, etc., which
may not be publicized by the chemical
producer, can have a negative effect on
the cleaning result.
When using cleaning agents and
specialized products it is essential
that the manufacturer’s instructions are
followed. Only use the product for the
application described by the
manufacturer to avoid any material
damage or the occurrence of strong
chemical reactions.
The machine must only be
operated with water and the
recommended cleaning agents.
Organic solvents must not be used in
the machine, as there is the danger
under certain circumstances of
explosion. Although this is not the case
with all organic solvents, other
problems could arise with their use,
e.g. damage to rubber and synthetic
materials.
IMPORTANT SAFETY INSTRUCTIONS
6

In critical applications where very
stringent requirements have to be
met, it is strongly recommended that all
the relevant factors for the process,
such as cleaning agent, quality of
water, etc. are discussed with a Miele
Applications Specialist.
The mobile units and special
inserts should only be used for
their specific application.
Empty any containers or utensils
before arranging them in the
machine.
Do not allow any remains of acids
or solvents, and in particular
hydrochloric acid, chloride solutions or
corroding ferrous material to get into
the wash cabinet. Similarly avoid any
materials with a corrosive effect. The
presence in compounds of any solvents
should be minimal.
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.
Please follow the advice on
installation in these instructions
and the separate Installation

To achieve good cleaning results, the
labwasher needs soft water. Hard tap
water results in calcium deposits on the
glassware and in the labwasher.
If your tap water hardness is above
4 gr/gal (values are in US gallons), the
water should be softened. This takes
place automatically in the unit's
integrated water softener.
To ensure a steady supply of soft water:
1. Make sure the water softener is
programmed correctly.
2. The salt reservoir must be filled with
reactivation salt.
The local water authority will advise you
on the water hardness in your area.
The machine is factory set to a water
hardness level of 19°d (20 gr/gal).
If the water hardness differs (even
under 4 gr/gal) the factory setting
must be adjusted via the electronic
control.
For fluctuating levels (e.g. 8 - 17 gr/gal
[8 - 17°d]) set the water softener to the
highest setting (in this example to
17 gr/gal).
Important! The built-in water
softener has settings from 1°d to
60°d.
Enter the local water hardness level
here: gr/gal
Setting the water softener
Miele's Technical Service sets the local
water hardness when installing and
commissioning the machine. See
"Operating/Reactivation" in the
Programming manual.
Regeneration display
When the message REACTIVATION
appears in the display, the built-in water
softener cannot supply any more soft
water. It must be reactivated
immediately after the program has
ended with reactivation salt.
If this cannot be done immediately, and
further batches have been washed,
then the reactivation process must be
carried out twice in succession.
Water softener (optional)
13

Filling the salt reservoir
Only special, coarse-grained
reactivation salt* should be used in
this machine.
*Available from Miele. Please see
back page for contact 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’s Professional Department.
The salt reservoir holds approx. 2 kg of
salt.
,Inadvertently filling the salt
reservoir with detergent will damage
the water softener.
Pressure builds in the salt container
and when removing it chemical
burns to the operator could result.
Before filling, make sure that you are
using reactivation salt.
^Unscrew the filter insert from the salt
container and remove.
^Fill the salt container with reactivation
salt and screw the filter insert back in
place.
^Remove mobile units, baskets and
inserts from the wash cabinet.
Water softener (optional)
14

Positioning the salt container
^Remove the plastic cap on the upper
right-hand side of the wash cabinet.
,The plastic cap may hold a small
amount of water which can be hot
depending on the last program run.
^Place the salt container on the
connector and screw firmly into
place.
Starting the reactivation
^Close the door.
^Open the water supply.
^Select the program REACTIVATION.
The reactivation program starts.
After the program has finished
^Turn off the machine.
^Open the door and carefully remove
the salt container. If the container will
not come off manually contact the
Miele Service Department.
^Replace the plastic cap.
^Return the mobile unit into the wash
cabinet.
^Turn off the water supply.
^Empty the salt container outside of
the wash cabinet.
^Rinse the salt container and filter
insert with water.
The water pressure (flow pressure at
water intake) must be at least
14.5 psi.
If it is below 14.5 psi or if it
fluctuates, the water softener will not
work properly. After reactivation, salt
remains may still be found in the salt
container.
To use up salt remains and to rinse out
the water softener, the REACTIVATION
program must be carried out again.
Water softener (optional)

In operating level C the (optional) AWK
allocates a fixed program place to a
mobile unit with valid coding.
Program places 1-15 are reserved for
the AWK automatic mobile unit
recognition.
The unit coding (on the mobile unit)
and the program place with the
corresponding program (in the
electronic control unit) have to
match each other.
Matching the coding and program
place
^Each mobile unit must be coded
before being used for the first time
(see "Setting the mobile unit coding").
^The wash program through which the
mobile unit is coded has to be
assigned to the relevant program
place (operating level D, see the
"System function - Selector Switch
Organization" section in the
Programming Manual).
Important!
Before starting the program with the
"Start" button 6, check if the
program needed for the mobile unit
is displayed.
Insufficient wash results may occur!
Always check that programs for
mobile units with automatic unit
recognition (AWK) (on fixed program
places) are not exchanged.
Mobile unit coding
The AWK assigns a program place to a
mobile unit. The mobile units must be
coded with a magnetic strip via a Bit
combination. In operating level C the
only program available for a coded
mobile unit is the one assigned to the
corresponding program place.
After a coded mobile unit has been put
in the machine and the door is closed,
the control unit selects the allocated
program.
Make sure that no small metallic
items (e.g. keys) stick to the
magnetic strip or its underside. The
coding might be not readable.
^Press 6to start the program.
Coding is affected through 5 Bits:
– Bit 1 through 4 define the mobile unit
code,
– Bit 5 serves as a control (Parity-Bit).
Automatic mobile unit recognition (AWK)
16

Mobile unit coding strip
15 different codes can be set. They are
assigned to program places 1 to 15.
Under "System function - Selector
switch organization" the matching
programs have to be put into the first
15 program places.

The coded total must be an even
number.
If the coded total is an odd number, the
message CHECK MOBILE UNIT
RECOGNITION appears.
If the mobile unit total equals 0, the
message NO MOBILE UNIT
RECOGNITION will appear. In neither
case can the program be started and
the mobile unit recognition function will
have to be reset.
Setting mobile unit coding
To set or alter the coding of a mobile
unit with the AWK proceed as follows:
^Unscrew the track with an Allen
wrench and remove from the retainer.
^Remove the magnetic strip from the
track.

^Set the program place coding.
^Put the magnetic strip back in the
track.
Important:
The magnetic strip must be placed
in the track so that the Bit coding set
according to the chart is visible
through the round windows in the
track.
^Place the track in the holder of the
mobile unit and screw firmly in place.
The magnetic strip on the G 7836
must have grey magnets.

The machine can be fitted with a variety
of mobile units, baskets and inserts,
depending on the cleaning application
in question.
The diversity of these units and inserts
is so great that it is not possible to
illustrate them all or give detailed
instructions on their use here. For
example, there are inserts for direct
spraying or rinsing of glassware which
contain internal surfaces, tubes and
pipes that need stringent cleaning.
Loading the machine
Removing excess soils
^Empty all containers before loading
them into the machine.
,Ensure that no acid or solvent
residues, especially hydrochloric
acid or chlorides get into the wash
cabinet.
Preparing the items for
cleaning
– Are the items to clean correctly
sorted and connected?
– Are the spray arms clean and can
they rotate freely?
– Is the filter combination free of
coarse soiling?
– Is the adapter to the water inlet in
place?
– Are the spray arms correctly
connected?
– Are the detergent and neutralizer
containers full?

Note
^Load the items to be washed so that
water can access all surfaces. This
ensures that they are properly
cleaned.
^Do not place items to be cleaned
inside other pieces where they may
be concealed.
^Hollow vessels such as beakers,
measuring cylinders, flasks, etc.
should be inverted and placed in the
correct inserts so that water can flow
in and out unrestricted. A cover net
can be used to reduce the risk of
movement during the wash process.
^Use a cover net (e.g. an A 2) or a
mesh tray for small items, to secure
lightweight items and to prevent them
from blocking the spray arms or
being caught in the magnetic strip on
the automatic mobile unit recognition
system.
^Deep based items should be placed
at an angle to allow water to run off
easily.
^Tall, narrow pieces should be placed
in the center of the baskets. This
ensures good water coverage.
^Mobile units and baskets with an
adapter must engage correctly.
^The spray arms must not be blocked
by tall items or items which hang in
their path. If necessary, manually
rotate the arms to test.
Select mobile units, baskets and
inserts appropriate for the
application.
