liquor ratios and, if necessary, disinfectants are to be used which
provide the necessary infection prophylaxis in accordance with
guidelines and microbiological and hygienic findings.
 Disinfection programmes must not be interrupted, as this can have
a limiting effect on the disinfection result. It is the operator's
responsibility to ensure that the standard of disinfection in thermal as
well as chemo-thermal procedures is maintained by carrying out
suitable validation tests.
 If special requirements are placed on the result quality of the
laundry, e.g. rinsing result, particle-free, wettability and permeability
to liquids, the process must be validated accordingly. The operator
must ensure the reprocessing standard through regular quality
controls.
 Gasoline, petroleum, kerosene, paraffin, or any easily flammable
liquid must not be stored or used near the washing machine. Risk of
fire and explosion.
 If the washing machine is operated in a publically accessible place,

Technical safety
 The washing machine must be installed by a Miele authorised
installer.
 Before installing and operating the washing machine, check it for
any visible exterior damage. Do not install or operate a damaged
washing machine.
 The electrical safety of this washing machine can only be
guaranteed when continuity is complete between it and an effective
earthing system which complies with current local and national safety
regulations. It is most important that this basic safety requirement is
present and regularly tested and, where there is any doubt, the on-
site wiring system should be inspected by a qualified electrician.
Miele cannot be held liable for the consequences of an inadequate
earthing system (e.g. electric shock).
 Unauthorised repairs could result in unforeseen dangers for the
user, for which the manufacturer cannot accept liability. Repairs
should only be carried out by a Miele approved service technician,
otherwise any subsequent damage will not be covered by the
warranty.
 Do not make any alterations to the machine, unless authorised to
do so by Miele.
 The washing machine must be disconnected from the mains
electricity supply before any maintenance, cleaning or repair work is
carried out. The washing machine is only isolated from the electricity
supply when
- it is switched off at the wall socket and the plug is withdrawn, or
- the mains fuse is disconnected, or

panels are in place so that it is impossible to touch an electrical
component or moving part.
 In the event of a fault or for cleaning and maintenance purposes,
the washing machine must be isolated from the electricity supply. It is
only completely isolated if:
- it is switched off at the wall socket and the plug is withdrawn, or
- the mains fuse is disconnected, or
- it is switched off at the mains circuit breaker.
 For further information see "Installation – Electrical connection".

Warning and Safety instructions
10
 The plug of the washing machine (if fitted) must be accessible at all
times to ensure that the washing machine can be disconnected from
the electricity supply at any time.
 The means for disconnection must be incorporated in the fixed
wiring in accordance with the wiring rules (AS/NZS 3000).
 The washing machine may only be connected to the water supply
using the new hose set supplied with the machine. Old hoses must
not be re-used. Check the hoses regularly for signs of wear. Change
the hoses in good time to avoid the risk of leaks and water damage.
The water flow pressure must be at least 100 kPa and must not
exceed 1000 kPa.
 Faulty components must only be replaced by genuine Miele
original spare parts. Miele can only guarantee the safety standards of
the machine when Miele replacement parts are used.
 If leakages occur, remedy their cause before operating the washing
machine again. Immediately disconnect the washing machine from
the electricity supply when leaking occurs.
 In case of malfunctions of the steam heater, temperatures in the
area of the drum door, the front of the detergent dispensing drawer
and the inside of the drum (especially the drum edge) may be
elevated. There is a risk of minor burns.
This only applies to appliances with steam heating.
 Please observe the instructions in "Installation".
 If the washing machine is hard wired, provision must be made on
site to switch off all poles from the electricity supply. The
disconnection switch must be located in the immediate area around
the washing machine, and must always be visible, accessible and
easily reachable.
 If the machine's mains connection cable has been damaged, it
must be replaced by the manufacturer or a qualified specialist.
 If maintenance or replacement of parts is carried out on the
machine, the power supply must be disconnected. If it is intended
that the mains plug be removed from the socket, the operator must
be able to clearly monitor from any access point that the mains plug
is still removed.

Warning and Safety instructions
11
Correct use
 The maximum load (dry laundry)
- for PW 6163: 16 kg
- for PW 6243: 24 kg
- for PW 6323: 32 kg
See the "Programme chart" for the maximum recommended loads for
individual programmes.
 Before using the machine for the first time, ensure that the transit
bars have been removed (see "Installation - Removing the transit
bars"). During spinning, transit bars which are still in place can cause
damage to both the machine and adjacent furniture or appliances.
 Never try to open the drum door of the washing machine using
force. The drum door can only be opened if appropriate information is
shown in the display.
 When washing with high temperatures, remember that the porthole
glass and the drum door become hot. Therefore, prevent children
from touching the porthole glass and the drum door during washing.
 Close the drum door after each wash programme. This way you
will avoid the danger of
- children climbing into the washing machine or hiding things in it.
- Small animals climb into the washing machine.
 Always close the drum door carefully. There is a risk of crushing
and cutting on the hinges of the drum door.
 It must be possible to open the drum door completely. The
opening range of the drum door must not be obstructed by doors or
structural conditions.
 Always make sure that the drum is stationary before reaching in to
remove laundry. There is a considerable risk of injury when touching a
drum that is still rotating.
 The procedures and machines listed here are not medical devices.
Observe the programme descriptions and procedural notes in the
programme chart.
 Disinfection of the laundry only takes place in the programmes with
a disinfection stage. All other programmes do not have a disinfection
stage (see programme chart - "Hygiene"). If laundry that has not been
disinfected is transferred to the "clean" side of the washing machine,
germ transfer or contamination can occur. The transfer of non-
disinfected linen to the "clean" side is the sole responsibility of the
operator.
 This washing machine may only be operated without supervision if
there is a floor drain (gully) in the direct vicinity of the washing
machine.

Warning and Safety instructions
12
 Disinfectants and detergents often contain chlorine-containing
compounds. If chlorine-containing agents dry on stainless steel
surfaces, the resulting chlorides can attack the stainless steel and
cause rust. You can protect your washing machine from rust damage
by using chlorine-free agents to wash, disinfect and clean the
stainless steel surface. If in doubt, have the manufacturer confirm that
the product is safe.
If agents containing chlorine get onto the stainless steel surface, the
stainless steel surface must be washed off immediately with water.
Then dry the stainless steel surface with a cloth.
 It is particularly important to observe the manufacturer's
instructions when using a combination of cleaning agents and special
application products. Products must only be used for applications
approved by the manufacturer to avoid any material damage or the
occurrence of strong chemical reactions. Confirmation must be
sought from the detergent manufacturer that using the agent in the
washing machine will not cause damage.
 If the correct amount of detergent is dispensed, the washing
machine should not need to be descaled. If, however, you do wish to
descale your washing machine, only use proprietary non-corrosive
descaling agents and strictly observe the instructions on the
packaging. Special descaling agent is available from Miele. Strictly
observe the instructions for the descaling agent.
 Turn off the tap if the machine is to be left for any length of time
(e.g. while on holiday), especially if there is no floor drain (gully) in the
immediate vicinity.
 Take care to ensure that foreign objects (e.g. nails, pins, coins,
paper clips) do not find their way into the machine with the laundry.
These may damage components of the machine (e.g. suds container,
drum). Damaged components can, in turn, result in damage to the
laundry.
 Fabrics that have been pre-treated in solvent-based cleaning
agents must be thoroughly rinsed in clean water before being placed
in the machine. Note that solvent residues may only be discharged
into waste water in compliance with local legislation.
 Never use solvent based cleaning agents, e.g. those containing
benzine, in this washing machine. This may result in damage to
component parts and create toxic fumes. Risk of fire and explosion!
 Do not store chemicals (liquid detergents, additives) on the
machine lid. They may cause discolouration or lacquer damage.
Accidently spilled chemicals should be removed from the surface
immediately with a wet cloth.
 A vent outlet is situated at the rear of the machine. It should never
be closed or covered. Observe the minimum distance in the
installation plan.

Warning and Safety instructions
13
 The application-technical recommendation of chemical washing
additives does not mean that the appliance manufacturer is
responsible for the effects of these addtives on the wash load and the
washing machine. Note that product changes not disclosed by the
manufacturer of these aids may affect the quality of the washing
result.
 Only use dyes, dye removers, and descaling agents suitable for
use in a washing machine. The manufacturer's instructions on the
packaging must be observed.
 Dye removers contain sulphur compounds which can cause
damage such as corrosion. Dye removers must not be used in the
washing machine.
 Check the washing result for laundry soiled with biological oils or
greases. Inadequately washed laundry can cause spontaneous
combustion during the drying process. Use special detergents or
wash programmes for such laundry.
 Do not use a pressure washer or hose to clean the washing
machine.
Chlorine and component damage
 Frequent use of chlorine products increases the risk of damage to
components.
 The use of substances containing chlorine, such as sodium
hypochlorite and chlorine bleach in powder form, can however result
in damage to the protective layer of stainless steel and corrosion on
components. Therefore, refrain from using agents containing chlorine.
Use oxygen-based bleaching agents instead.
If, however, chlorine bleaching agents are used, an anti-chlorine
treatment must always be carried out. Otherwise, the washing
machine components and the load may suffer lasting and irreparable
damage.
 Anti-chlorine treatment must be carried out immediately after
chlorine bleach has been used. Hydrogen peroxide and oxygen-
based detergents and bleaching agents are suitable for anti-chlorine
treatment. The suds must not be drained in between.
Treatments with thiosulphates can result in gypsum-like deposits,
particularly in combination with hard water. This gypsum can build up
in the washing machine or cause incrustations on the laundry.
Treatment with hydrogen peroxide is recommended over treatment
with thiosulphates because hydrogen peroxide neutralises chlorine.
The exact dispensing quantities and the treatment temperatures
required must be set and tested on site in accordance with the
dispensing recommendations of the detergent and additive
manufacturers. The laundry must also be tested to check whether it
contains any active chlorine residues.

Warning and Safety instructions
14
Accessories
 Only use genuine Miele spare parts and accessories with this
machine. Using spare parts or accessories from other manufacturers
will invalidate the warranty, and Miele cannot accept liability.
Miele cannot be held liable for damage caused by non-compliance
with these Warning and Safety instructions.
Disposing of your old appliance
 Ensure that the door locks are unusable when disposing or
scrapping old washing machines. This way you will prevent the risk of
playing children accidentally locking themselves in and endangering
their lives.

Caring for the environment
15
Disposal of the packing material
The packaging is designed to protect the washing machine from
damage during transportation. The packaging materials used are
selected from materials which are environmentally friendly for
disposal and should be recycled.
Recycling the packaging reduces the use of raw materials in the
manufacturing process and also reduces the amount of waste in
landfill sites. 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!
Disposing of your old appliance
Electrical and electronic appliances often contain valuable materials.
They also contain specific materials, compounds and components,
which were essential for their correct function and safety. These
could be hazardous to human health and to the environment if
disposed of with your domestic waste or if handled incorrectly.
Please do not, therefore, dispose of your old appliance with your
household waste.
Please dispose of it at your local community waste collection /
recycling centre for electrical and electronic appliances. You are also
responsible for deleting any personal data that may be stored on the
appliance prior to disposal. Please ensure that your old appliance
poses no risk to children while being stored prior to disposal.

Caring for the environment

Energy saving tips
Energy and water
consumption
- To get the most out of your machine, load the maximum dry load
for the programme you are using.
The most efficient use of energy and water is achieved when a full
load is washed.
Detergent - Do not exceed the amounts of detergent recommended by the
manufacturer on the packaging.
- Reduce the amount of detergent for smaller loads.
When drying with
a tumble dryer
Selecting the highest possible spin speed for the wash programme
will save energy when drying in a tumble dryer afterwards.
