cleaned.
Avoid inhalation of powder cleaning
~
agents. They can cause burning in the
mouth and throat if swallowed, and can
inhibit breathing.
Only use low-foaming cleaning
~
agents. Incorrect cleaning agents, as
well as some types of soiling can cause
a build-up of foam in the machine.
Foam can have an adverse effect on
the cleaning process.
Please be aware that changes in
~
formulation, storage conditions etc,
which may not be publicised by the
chemical producer, can have a
negative effect on the cleaning result.
When using cleaning agents and
~
specialised products, it is essential that
the manufacturer's instructions are
followed. Only use such chemicals for
the purpose and in the situation
specifed, 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 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).
11
Warning and Safety instructions
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).
Never clean the machine or near
~
vicinity with a water hose or pressure
washer.
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.
After any plumbing work the water
~
pipework to the machine will need to be
vented.
If this is not done the softener system
could suffer damage.
While the machine is under
~
guarantee, repairs should only be
undertaken by a service technician
authorised by the manufacturer.
Otherwise the guarantee will be
invalidated.
Be careful when sorting items with
~
sharp pointed ends and positioning
them in the machine that you do not
hurt yourself or create a danger for
others. Sharp knives, forks etc. should
be placed in baskets with the pointed
ends facing downwards.
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
~
or the heated surfaces on the wash
cabinet floor 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.
Empty any containers or utensils
~
before arranging them in the machine.
Do not sit or lean on the opened
~
door. This could cause the machine to
tip up and be damaged or cause an
injury.
12
Warning and Safety instructions
Installation
This machine may only be used in
~
mobile installations such as ships,
caravans, aircraft etc. if a risk
assessment of the installation has been
carried out by a suitably qualified
engineer.
Do not install the machine in an area
~
where there is any danger of explosion
or of freezing conditions.
Safety with children
This machine is not a toy! Keep
~
children away from it at all times and
supervise them whilst you are using it.
They will not understand the potential
dangers posed by it. For instance whilst
playing they could inadvertently shut
themselves inside it.

~
allowed to use it unsupervised if its
operation has been clearly explained to
them and they are able to use it safely,
recognising the dangers of misuse.
Accessories
Only use genuine Miele spare parts
~
and accessories with this machine.
They must be suitable for the purpose
they are being used for. Consult Miele
for advice.
If spare parts or accessories from other
manufacturers are used, this will
invalidate the guarantee, and Miele
cannot accept liability.
13
Warning and Safety instructions
Disposing of an old
dishwasher
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 inoperable, so that
children cannot accidentally shut
themselves in. Then make appropriate
arrangements for the safe disposal of
the machine.
For tank system machines ensure that
any water is emptied out of the tank.
The manufacturer cannot be held
liable for damage caused by
non-compliance with these Warning
and Safety instructions.
14
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 offered for recycling.
Disposal of your old machine
Electrical and electronic appliances /
machines 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 or machine. Please do
not therefore dispose of your old
machine or appliance 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.
15
Before using for the first time
Before using the machine for the first
time, the following steps must be
carrried out.
Each step is described in more
detail in the appropriate section
further on in the booklet.
Prepare the water softener unit
(Optional).
Only use cleaning agents formulated
for use in this type of machine.
Do not use cleaning agents designed
for domestic dishwashers.
Add cleaning agent
Follow the cleaning agent
manufacturer's recommendations on
dosage.
The water softener unit must be set for
the water hardness level in your area.
The salt reservoir also has to be filled,
first with water and then with
reactivation salt.
Inadvertently filling the salt
,
reservoir with cleaning agent always
leads to serious damage to the
water softener. Make sure you have
picked up the correct packet of
reactivation salt before filling the salt
reservoir!
Load the machine carefully
Arrange the load so that water will
come into contact with all surfaces.
Concealed surfaces will not be
cleaned.
The spray arms must not be blocked by
any items.
The amount required will depend on the
type of cleaning agent used and the
programme selected.
Read the notes on dosage given in
the programme chart.
Cleaning results may vary from brand
to brand. If you are not satisfied with
the results from one brand, try another
quality brand before contacting Miele
for advice.
The filter combination in the floor of
the wash cabinet and also the spray
arms must be kept clean.
It is therefore absolutely essential to
check and clean them regularly.
16
Opening and closing the door
To open the door
Grasp the handle and open the door.
^
The door should only be opened during
operation for emergencies, e.g. if
articles are knocking together or if a
programme fault is indicated in the
display (see "Cancelling a
programme").
Do not touch the inside of the
,
cabinet or the heated surfaces
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.
To close the door
Lift the door upwards and push until
^
it clicks shut.
17
Water softener unit (optional)
Only applies to machines with a
built-in water softener.
Important
The built-in water softener has settings
from 0.2 - 6.5 mmol/l (1 °d - 35 °d ).
To achieve good cleaning results, the
dishwasher needs to operate with soft
water. Hard water results in a build-up
of calcium deposits on crockery and in
the dishwasher.
To ensure a steady supply of soft water:
1. the water softener unit must always
be programmed correctly, 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 water softener unit 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.
Where the water hardness level is
above 5.4 mmol/l (30 °d) an external
water softener unit, e.g. the G 7897
Aqua-soft system will need to be fitted.
In the case of a fault, it will help the
service technician if you know the
hardness of your local water supply.
Enter your water hardness level here:
mmol/l or °d
Your local water authority will advise
you on the water hardness in your area.
Where the water hardness level
fluctuates, e.g. 1.4 - 3.1 mmol/l
(8 - 17°d), set the water softener to the
highest setting (3.1 mmol/l (17 °d) in
this example).

Filling the salt reservoir
Only use special coarse grained
reactivation salt with granules of
approx. 1-4 mm. Do not use other salts
such as cooking salt, agricultural grade
or gritting salt. These may contain
insoluble additives which can impair
the functioning of the water softener. If
in doubt consult the Miele Professional
Department.
The salt reservoir holds approx. 1.5 kg
of salt.
Inadvertently filling the salt
,
reservoir with cleaning agent always
leads to serious damage to the
water softener. Make sure you have
picked up the correct packet of
reactivation salt before filling the salt
reservoir!
^ Remove the bottom basket from the
machine.
^ Unscrew the salt reservoir cap.
Place the funnel provided over the salt
^
reservoir and carefully fill with
reactivation salt until it is full.
As it is filled, displaced water will run out.
^ Remove the funnel and wipe any
residual salt off the screw threads on
the socket.
^ Screw the cap back on firmly.
^ Close the machine door and press one
of the programme buttons.
Before filling the salt reservoir with
salt for the first time fill it with
approx. 2 litres of water.

If there is still water in the tank,
e.g. if you are refilling the salt
reservoir, you will need to run the
"Drain" programme beforehand.

The rinsing process will begin which will
dilute and flush out any residual salt. The
display will show the duration remaining
until the machine can be used again.
After the rinsing process has begun,
there may be a pause for a few
minutes whilst the water softener is
regenerated.
If the boiler and tank are full and the
operating temperature has been
reached, the rinsing time of the
programme selected will be shown in
minutes. The machine is now ready for
operation.
