Warning and safety instructions
Warning and safety instructions
This machine meets all the statutory
safety requirements. Improper use
may cause accidents and damage
to the machine.
Before installation and before using
the machine for the first time, read
the operating instructions carefully.
This way you will avoid the risk of
accidents and damage to the machine.
Keep the operating instructions in a
safe place.
Specified use of the machine
This machine is only authorised for
the applications mentioned in the
operating instructions. Do not use the
machine for purposes other than those
for which it was designed, as this
might be dangerous. The manufacturer
cannot be held responsible for damage caused by improper use of the
machine.
The electrical safety of this ma-
chine can only be guaranteed
when continuity is complete between
the appliance and an effective earthing
system. It is imperative that this basic
safety requirement is tested and where
there is any doubt, the electrical system should be checked by a qualified
electrician. The manufacturer cannot be
held responsible for damage caused by
the lack or inadequacy of an effective
earthing system (e.g. electric shock).
A damaged machine poses a
safety risk. Disconnect the machine immediately from the mains supply and inform a suitably qualified service technician.
Repairs should only be carried out
by suitably qualified and competent service technicians. Repairs by unqualified persons could be dangerous.
The machine should not be oper-
ated by unauthorised personnel.
Please note the following in order to
prevent accidents
Commissioning and repairs should
only be carried out by a suitably
qualified and competent Miele service
technician, an authorised Miele service
dealer or by other suitably qualified and
competent service technicians.
Do not install the machine where
there is a risk of explosion or
where sub-zero temperatures may
occur.
Take care when handling liquid
cleaning agents/additives. These
may contain irritants or corrosive substances. Do not use organic solvents
as there may be the danger of explosion.
Carefully follow the relevant safety instructions on packaging and wear protective gloves and goggles.
5
Warning and safety instructions
Avoid inhaling powder dust.
Swallowing detergent may cause
burns or even lead to suffocation.
The water in the machine must not
be used as drinking water.
Do not sit or lean on the open door.
This could cause the machine to
tip and be damaged.
Be careful when sorting sharp
pointed instruments not to injure
yourself. If necessary, place the
pointed end downwards with the
handles pointing upwards.
When using the machine at high
temperatures take care as the load
is extremely hot and may cause burns.
Baskets and inserts must first be
allowed to cool. Empty any water still remaining in concave items into the
cabinet before removing the load.
Do not touch the heating elements
after the end of a programme as
this may cause burns.
Never use a hose or a high-press-
ure cleaner on or in the vicinity of
the machine.
Before carrying out repairs, discon-
nect the machine from the mains
supply (switch off at the main socket
and pull out the plug, switch off the
appropriate circuit at the fuse box or
withdraw the mains fuse).
Please heed the following instructions in order to guarantee the quality
of cleaning performance and to
avoid damage.
Only use detergents which have
been tested and recommended by
Miele for use in special dishwashers.
Use of other cleaning agents may
cause damage to both the load and the
machine.
Prior treatment (e.g. with deter-
gent), but also certain types of soil
and some detergents may cause foaming which may have an adverse effect
on the quality of cleaning.
The recommendation of specific
chemical products (e. g. detergent) for individual applications does
not mean that the appliance manufacturer accepts responsibility for any
effect these may have on the articles
being processed.
Please note that variations in composition, storage conditions, etc., which
are not always announced by the detergent manufacturer, may affect the
quality of the cleaning results.
When using detergents and spe-
cial cleaning agents, take particular care to follow the manufacturer’s
instructions. Only use the appropriate
cleaning agent for the application
recommended by the manufacturer.
Improper use may cause damage to
material, or in some cases lead to
severe chemical reaction (e.g. oxyhydrogen explosion).
6
Warning and safety instructions
Only use water and cleaning agents
in this machine. Do not use organic
solvents as there may be a danger of
explosion.
(Note: There are many organic solvents
which do not pose a risk of explosion,
but may cause other problems, such as
damage to elastomers and plastic components).
In the case of critical applications
requiring a particularly high standard of cleaning, cleaning programmes
and parameters (detergent, quality of
water, etc.) should be coordinated with
the Miele Applications Technology
Department.
If a particularly high standard of
cleaning and rinsing is required
(e. g. chemical analysis, special industrial production, etc.), regular quality
checks must take place to guarantee
the correct standard of cleaning.
Use special inserts in accordance
with the instructions provided.
Do not allow any acid or solvent
residue, especially hydrochloric
acid and solutions containing chloride
to get into the wash cabinet. This also
applies to ferrous components susceptible to corrosion.
Only traces of solvent in conjunction
with soil (particularly for the highest risk
category) are permissible.
Take care that solutions/vapours
containing hydrochloric acid do
not come into contact with the stainlesssteel casing, as this may cause corrosion.
Please heed installation instruc-
tions and refer to the installation
diagram supplied with the machine.
Empty all concave items before
placing them in the machine.

Warning and safety instructions
Use of accessories
Only Miele accessories designed
for the appropriate application
should be connected to the machine.
Model designations of individual
appliances can be obtained from the
Miele Application Technology Department.
Disposal of old appliances
Before discarding an old machine,
unplug it and render the plug useless. For environmental and safety
reasons, ensure that the machine is
completely drained of any residual
cleaning agent. Observe safety regulations and wear safety goggles and
gloves. Make the door inoperative by
removing the lock pin (2 Phillips screws
above the door). This will prevent children from accidentally locking themselves in. Then make appropriate
arrangements for the safe disposal of
the appliance. For machines with a tank
system, ensure that the tank is evacuated before disposal of the appliance.
The manufacturer cannot be held
responsible for damage caused by
failure to heed the warning and
safety instructions.
In countries where there are areas
which may be subject to infestation by cockroaches or other vermin,
pay particular attention to keeping the
machine and its surroundings in a
clean condition at all times. Any damage which may be caused by cockroaches or other vermin will not be
covered by the machine guarantee.

Description of the machine
This Miele machine is a frontloading
commercial dishwasher with appropriately short batch times specially
designed for use in family restaurants,
fast food outlets, cafés, guest houses,
etc.
Description of the machine
This machine is
softener as standard.
A water softener is required in areas
with a supply hardness of more than
6°d (1.07 mmol/l).

Setting the water softener
Setting the water softener
- Only for machines with a built-in water
softener -
To avoid the build up of calcareous deposits on both the load and the machine,
the water needs to be softened, if supply
hardness is over 6°d (1.07 mmol/l).
To ensure a steady supply of soft water,
the built-in water softener must always
be:
1. Correctly set
2. Topped up with salt as soon as the
k indicator light goes on.
When commissioning a machine the
water softener must be set to correspond with supply hardness.
Your local water authority will advise
you on the supply hardness in your
area.
Setting the water softener
The hardness range is divided into 18
units and a zero position. The dishwasher is set at the factory for a water
hardness time setting "8", corresponding to 19°d (3.38 mmol/l).
If your water supply is softer than this,
then:
Change the setting on the controls
(see table).
