Warning and Safety instructions
Personnel operating the machine
should be trained regularly.
Untrained personnel must not be
allowed access to the machine or its
controls.
This machine is not a toy! Do not allow
children to play in or around it, or to
operate it. There is a danger they could
injure themselves, or get into the
machine and lock themselves in.
Take great care when handling
liquid agents and additives. These
may contain irritant or corrosive
ingredients. Do not use organic
solvents as these could cause an
explosion.
Follow all relevant safety procedures
carefully. Wear protective gloves and
goggles. With all chemical agents, the
manufacturer’s safety conditions must
be observed.
Avoid inhalation of powder
cleaners. They can cause burning
in the mouth and throat if swallowed,
and can inhibit breathing.
When using this machine in the
higher temperature ranges, be
especially careful not to scald or burn
yourself when opening the door.
Baskets and inserts must be allowed to
cool down before they are unloaded.
Any water remaining in containers
could still be very hot. Empty them into
the wash cabinet before taking them
out.
Do not touch the heating elements
if you open the door during or
directly after the end of a programme:
you could burn yourself. They remain
hot for some time after the end of the
programme.
Never clean the machine or near
vicinity with a water hose or a high
pressure hose.

8
The following points should be
observed to assist in maintaining
quality standards, to protect users,
and to avoid damage to the machine
and items being cleaned.
If the machine is being used for
disinfection in accordance with
official regualtions on the control of
epidemics, the steam condenser and
its connections to and from the wash
cabinet must be cleaned and
disinfected whenever any repairs are
carried out or parts replaced.
Warning and Safety instructions
When running a disinfecting
programme in accordance with
official regulations on the control of
epidemics, the programme must not be
interrupted once it has been started
(see Cancelling a programme in an
emergency).
The standard of disinfection in the
disinfection programmes must be
routinely confirmed by the user. The
process should be regularly monitored
using thermo-electrical, chemical or
bio-indicators, and this should be fully
documented.
Disinfection programmes must not
be interrupted as this can have a
limiting effect on the disinfection result.
If interruption is unavoidable, however,
the complete programme must be
repeated.
For thermal disinfection, use
temperatures and temperature
holding times to achieve the required
infection prophylaxis in accordance
with current health and safety
regulations.
Only use Miele approved cleaning
agents in this machine. Using
unsuitable cleaning agents could
adversely affect the components of the
machine, as well as items being
cleaned.
For pre-treatment and/or cleaning,
only use low-foaming cleaning and
disinfecting agents which have been
approved by Miele. Foam can have an
adverse effect on the disinfection and
cleaning process.
Where a chemical additive is
recommended on technical
application grounds (e.g. a cleaning
agent), this does not imply that the
manufacturer of the machine accepts
liability for the effect of the chemical on
the items being cleaned.
Please be aware that changes in
formulation, storage conditions etc.
which may not be publicised by the
chemical manufacturer, can have a
negative effect on the cleaning result.
When using cleaning agents and
special application chemicals, it is
essential that the manufacturer’s
instructions are followed. Only use such
chemicals for the purpose and in the
situation specified, to the exclusion of
other chemicals, to avoid such dangers
as chemical reactions and material
damage.
The machine is designed for
operation with water and additive
cleaning agents only. Organic solvents
must not be used in this machine, as
there is the danger under certain
circumstances of fire or explosion.
(Although this is not the case with all
organic solvents, other problems could
arise with their use, for example
damage to rubber and synthetic
materials).
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, water quality
etc. are discussed with the Miele
Application Technology specialists.
9
Warning and Safety instructions
If cleaning and rinsing results are
subject to particularly stringent
requirements (e.g. chemical analysis,
specialised industrial processes etc.), a
regular quality control test must be
carried out by the user to ensure that
required standards of cleanliness are
being achieved.
The special inserts should only be
used for their specific application.
Hollow instruments must be thoroughly
cleaned, internally and externally.
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 or chloride solutions,
to get into the wash cabinet. Similarly
avoid any materials with a corrosive
effect.
The presence in compounds of any
solvents should be minimal (especially
those in hazard class A1).
To avoid any 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
Instructions.
Using accessories
Only use genuine Miele
accessories with this machine.
Consult Miele on the type and
application of such equipment.
Only use Miele mobile units,
baskets and inserts in this
machine. Using accessories made by
other manufacturers, or making
modifications to Miele accessories can
result in unsatisfactory cleaning and
disinfecting results, for which Miele
cannot be held liable. Any resultant
damage would also invalidate the
machine guarantee.
Disposal of your old machine
Before disposing of your old
machine first make it unusable.
Disconnect from the mains, cut off the
cable near the machine and any plug
from the cable.
For environmental and safety reasons
ensure the machine is completely
drained of any residual water and
cleaning agent. (Observe safety
regulations and wear safety goggles
and gloves).
Make the door lock inoperative, so that
children cannot accidentally shut
themselves in. Then make appropriate
arrangements for the safe disposal of
the machine.
The manufacturer cannot be held
liable for damage caused by
non-compliance with these Warning
and Safety instructions.
10
Caring for the environment
Disposal of the packing
material
The transport and protective packing
has been selected from materials which
are environmentally friendly for disposal
and can normally be recycled.
Ensure that any plastic wrappings,
bags etc. are disposed of safely and
kept out of the reach of babies and
young children. Danger of suffocation.
Rather than just throwing these
materials away, please ensure that they
are recycled.
Disposal of your old appliance
Electrical and electronic appliances
often contain materials which, if
handled or disposed of incorrectly,
could be potentially hazardous to
human health and to the environment.
They are, however, essential for the
correct functioning of your appliance.
Please do not therefore dispose of it
with your household waste.
Please dispose of it at your local
community waste collection / recycling
centre and ensure that it presents no
danger to children while being stored
for disposal.
It should be unplugged or disconnected
from the mains electricity supply by a
competent person. Any plug must be
rendered useless and the cable cut off
directly behind it to prevent misuse.
See the "Warning and Safety" section of
this booklet for further details.

Water softener
The water needs to be softened to
avoid calcium deposits building up on
instruments and utensils and in the
machine itself.
To ensure a steady supply of soft water
the water softener unit must always be:
1. correctly set (programmed) and
2. the salt reservoir must be filled.
(If the water hardness level is below
0.7 mmol/l (4 °d - German scale) the
reservoir does not need to be filled
with reactivation salt.)
The machine is set at the factory for a
water hardness level of 3.4 mmol/l
(19 °d).
If the water supply is harder or softer
than this (including below 0.7 mmol/l
or 4 °d) the factory setting will need
to be changed following the
instructions in "Setting the water
softener". See chart on the next
page for settings.
Your local water authority will advise
you on the water hardness in your area.
For fluctuating levels (e.g. 1.4 - 3.1
mmol/l or 8 - 17 °d) set the water
softener to the highest setting (in this
example to 3.1 mmol/l or 17 °d).
Important
The built-in water softener has settings
from 0.2 - 10.8 mmol/l or 1 °d - 60 °d.
