Quality assurance
The following points should be observed to assist in maintaining quality standards when
reprocessing laboratory glassware and utensils and to avoid damage to the loads being
cleaned.
Only authorised personnel may interrupt a programme in exceptional circumstances.
It is the responsibility of the operator to demonstrably ensure reprocessing standards in
routine operation. Process results must be inspected and documented on a regular basis.
For thermal disinfection, use temperatures and temperature holding times to achieve the
required infection prophylaxis in accordance with current health and safety regulations.
Only reprocess undamaged and suitable items. When washing plastic items, ensure that they
are thermally resistant. Nickel-plated items and items made of aluminium require special
procedures and are not generally suitable for machine reprocessing. Ferrous materials that can
rust or corrode must not be introduced into the wash chamber as wash items or soiling.
Under certain circumstances, process chemicals may damage the machine. Users are urged
to follow the recommendations issued by manufacturers of process chemicals. Contact Miele in
the event of damage and any suspicion of material incompatibility.
Cleaning agents containing chlorine can damage the elastomers of the machine.
If cleaning agents containing chlorine have to be used, a maximum temperature of 70 °C in the
“Main wash” programme blocks is recommended (see programme chart).
Abrasive substances should not be introduced into the machine as these could cause
damage to mechanical components in the water circuit. Abrasive residues on the load must be
removed completely before reprocessing.
Pre-treatment with cleaning or disinfecting agents, some types of stains and the interaction of
certain process chemicals can create foam. Foam can have an adverse effect on the disinfection
and cleaning result.
Reprocessing should not result in foam being discharged from the chamber. Foam discharge
can compromise the operation of the machine.
The process used must be monitored on a regular basis by the operator to check foaming
levels.
Even when a process chemical, e.g. detergent, is recommended, Miele takes no responsibility
for the effect of such chemicals on the load items. Please note that changes in product
formulation, storage conditions, etc., which are not announced by manufacturers of process
chemicals may impair the quality of cleaning results.
Always follow the relevant manufacturer's instructions on storage and disposal of process
chemicals.
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 detergents, water quality, etc.,
are discussed with Miele.
If the cleaning result is subject to particularly stringent requirements (e.g. chemical analysis),
regular quality control should be carried out by the operator to ensure that required standards of
cleanliness are being achieved.
Load carriers such as mobile units, baskets and inserts which hold the load must be used only
as intended.
Lumened items must be thoroughly cleaned, internally and externally.
Secure small and light items with cover nets or place in a mesh tray for small items, so that
they do not block the spray arms.
Empty any containers or utensils before loading them.
The amount of residual solvents on items going into the wash chamber should be minimal.
There should be no more than a trace of any solvents with a flash point of below 21 °C.
PRODUCT INFORMATION
REV.0.01_COD.650138_A4

PRODUCT INFORMATION
Chloride solutions, in particular hydrochloric acid, or ferrous materials that can rust or corrode
must not be placed in the chamber.
Ensure that solutions or steam containing chlorides or hydrochloric acid do not come into
contact with the stainless steel outer casing of the machine in order to avoid any damage through
corrosion.
After any plumbing work, the water pipework to the machine will need to be vented. If this is
not done, machine components can be damaged.
The gaps between a built-in machine and adjacent cabinetry must not be sealed, e.g. with
silicone sealant, as this could compromise ventilation of the circulation pump.
Follow the installation instructions in the operating and installation instructions.
Safety with children
Children should be supervised in the vicinity of the machine. Do not allow children to play with
the machine. There is a danger that children might shut themselves in the machine.
Children must not use the machine.
Keep children away from process chemicals. These contain irritant and corrosive ingredients
which can cause burning in the eyes, mouth and throat, or inhibit breathing. It is therefore
important to keep children away from the machine when the door is open. There could still be
residual process chemicals in the machine. Observe the safety data sheets for the process
chemicals and seek medical advice immediately if a child has swallowed process chemicals or
got them in their eyes.

Using accessories
Only use genuine Miele original spare parts and accessories suitable for the application they
are required for. Model designations are available from Miele.
Only use Miele load carriers, such as mobile units, baskets, modules and inserts. Using
mobile units, baskets and inserts made by other manufacturers or making modifications to Miele
accessories can result in an unsatisfactory cleaning and disinfection result. Any resultant damage
would not be covered by the warranty.
Disposing of your old appliance
Please note that the machine may contain contamination from blood and other bodily fluids,
pathogens, facultative pathogens, genetically modified material, toxic or carcinogenic substances,
heavy metals, etc., and must be decontaminated before disposal.

3. INSTALLATION
3.1 Water connection
Water quality
The quality of the water used in all the cleaning stages is essential in achieving good results.
The water must be compatible with the material from which the machine is made.
The water must be compatible with process chemicals.
The water must be compatible with process requirements for the various stages of the
process.
In order to achieve good reprocessing results, the machine requires a supply of soft water with a
low calcium content. Hard water results in the build-up of calcium deposits on the load and in the
machine.
Water with a hardness level higher than 0.7 mmol/l (4 °dH – German scale) must be softened. This
occurs automatically during a programme sequence on machines with a built-in water softener
(option ex works). The water softener must be set to the exact hardness of the water supply.
The water softener must be reactivated at regular intervals. This requires the use of special
reactivation salt. Reactivation is carried out automatically during a programme sequence.
Softened water must be provided on site for machines without a built-in water softener.
INSTALLATION
Note: The water hardness is set by the Miele Customer Service Department.
CAUTION
Water from the chamber is not suitable for drinking!
The machine must be connected to the water supply in strict accordance with local regulations.
The water used must comply with European regulations for drinking water quality as a minimum. If
the water supply has a high iron content, there is a danger of corrosion occurring on items being
cleaned in the machine, as well as the machine itself. If the chloride content of the water exceeds
100 mg/l, the risk of corrosion to the load in the machine will be further increased.
In certain regions (e.g. mountainous areas), the water composition may cause precipitates to form,
requiring the use of softened water in the steam condenser.
The machine is supplied as standard for connection to cold water (blue coded hose) and hot
water up to max. 60 °C (red coded hose). Connect the inlet hoses to the valves for cold and hot
water.
If no hot water supply is available, the red coded inlet hose for the hot water connection must also
be connected to the cold water supply.
The minimum flow pressure for cold water, hot water and DI water connections is 100 kPa.
The recommended flow pressure is ≥ 200 kPa for the cold and hot water connections and
≥ 200 kPa for the DI water connection in order to avoid excessively long water intake times.
The maximum permissible static water pressure is 800 kPa.
A booster pump is required if the flow pressure is below 100 kPa. If the pressure is higher than
800 kPa (8 bar), a pressure reducer must be installed.
If water pressure is not within the specified range, contact the Miele Customer Service
Department or an authorised service technician for advice.
REV.0.01_COD.650138_A4
Page 17
Page 18
INSTALLATION
A stopcock valve with a ¾” male threaded union must be provided on site. The valve should be
easily accessible, since the water supply should be shut off whenever the machine is not in use.
CAUTION
Do not overtighten the threaded unions on the hoses.
Information:
If no hot water supply is available, the red coded inlet hose for the hot water connection
must also be connected to the cold water supply.
A Y-piece can be used to connect both hoses to the cold water supply.
Miele cannot be held liable for damage or injury caused by non-compliance with the safety
instructions and warnings.
Non-compliance with the above conditions will render the warranty invalid.

4.1 Salt refill indicator
If the salt level in the salt container is low, the following reminder will appear in the display: “salt
loading”.
REV.0.01_COD.650138_A4
Page 20
Page 21
4.2 Refilling the salt
Use only special, coarse-grained dishwasher salt or other pure evaporated salt for reactivation.
Never use any other kind of salt, e.g. table salt, animal feed salt or de-icing salt. Other salts may
contain insoluble additives which can impair the functioning of the water softener.
The following prompt reminds the user to refill the salt container:
“salt loading”
The container for dishwasher salt is located in the base of the wash chamber inside the machine.
Open the door.
Remove the load carrier.
Unscrew the plastic cap on the container.
Fill the funnel with salt.
Raise the funnel by the handle and place it on the container.
Release the handle. The salt then passes from the funnel into the container.
Repeat the process until the container is visibly full.
BUILT-IN WATER SOFTENER (OPTIONAL)
The supply container contains approx. 780 g of salt.
CAUTION!
The container must always be completely filled. If filled to less than full, the
water softening capacity is reduced and limescale deposits may occur on the
load and on wash chamber surfaces.
Refit the plastic cap on the salt container and screw tight.
Place the load carrier in the machine.
Start the “Rinse” programme.
CAUTION!
Always run the “Rinse” programme after refilling the salt. This removes and
dissolves spillages of salt and brine. Excess salt and brine which has
overflowed can cause corrosion damage if they are not rinsed away.
CAUTION!
During reactivation, the following appears on the display: “regeneration”.

17. MAINTENANCE
17.1 General recommendations on maintenance
Maintenance for the machine described in this manual can be divided into routine maintenance
and special maintenance.
Machine status
The machine must be completely switched off. The person performing the task must ensure that
the safety of others in the vicinity is not compromised.
Safety systems
The machine should only be operated in compliance with valid standards and regulations relating
to the use of disinfectants (cf. data sheets for individual products). Rules relating to contact with
machine parts potentially contaminated with pathogens also apply. Personal protective gear must
be worn.
Procedure
If possible, run a disinfection programme for the wash chamber. Open the wash chamber door
and wipe with a suitable disinfectant.
Wipe all internal parts as well as any baskets and their contents.
Leave the disinfectant to act for the required amount of time (see the product data sheet or safety
data sheet for the disinfectant in question).
When performing maintenance on parts of the machine which have not been reached by the
disinfectant, take appropriate precautions and use suitable safety gear.
Decontamination procedures
Before making repairs or replacing mechanical parts (e.g. drain pump, heating elements, etc.) in
cases where disinfection has not been completed, the disinfection procedure must first be carried
out in order to eliminate any pathogenic residues.

Please note that the machine may contain contamination from blood and other bodily fluids,
pathogens, facultative pathogens, genetically modified material, toxic or carcinogenic substances,
heavy metals, etc., and must be decontaminated before disposal.
For environmental and safety reasons, dispose of all process chemical residues in accordance
with safety regulations. Wear gloves and protective goggles.
Make the door lock inoperable, so that children cannot accidentally shut themselves in the
machine. Then make appropriate arrangements for safe disposal of the machine.
Old electrical and electronic appliances often contain valuable materials. However, they also
contain harmful substances which were essential for their correct functioning and safety. These
could be hazardous to human health and to the environment if disposed of with general waste or if
handled incorrectly. Please do not, therefore, dispose of your old appliance with general waste.
Make use of local waste collection/recycling centres for electrical and electronic devices. Consult
your dealer if necessary. National legislation may require the deletion of personal data saved on
the machine before disposal. Please ensure that your old appliance poses no risk to children while
being stored prior to disposal.
