The water recycling unit “WRG” must only be installed by an
approved Service technician or authorized Service Dealer.
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.
Disposal of old machines or appliances
Old machines or appliances contain materials which can be re-cycled. Please contact your local authorities or
scrap merchant about potential recycling schemes, before disposing of the machine or appliance. See also the
section under “Warning and Safety instructions”.

Warning and Safety instructions
To avoid danger of cross infection no
water must be recycled from programmes
treating laundry which may be infectious.
Water being recycled must never be
used as drinking water.
This water recycling unit must only be
used for water which has not come in con-
tact with dangerous or inflammable materials.
On no account use high pressure
cleaners or hose down the machine.
Disinfecting and cleaning agents often
contain chlorides (salts). If these substances dry on steel surfaces the residual
chlorides attack the steel and can cause rusting.
To protect your machine from rust damage
we recommend only using chloride free disinfecting and cleaning agents for washing and
disinfecting, and for cleaning the machine. If
you are not sure about a particular agent, contact the manufacturer for advice.
If you accidentally spill an agent containing
chloride on the machine it should be rinsed
off with water and dried using a soft cloth.
Accessories
Accessory parts may only be fitted when
expressly approved by Miele. If other
parts are used, guarantee, performance and
product liability claims may be invalidated.
It is also essential to read the operating in-
structions for the washer extractor.
Keep these instructions in a safe place.
The electrical safety of this appliance can
only be guaranteed when continuity is
complete between the appliance and an effective earthing system which complies with local
and national regulations.
It is most important that this basic safety requirement is regularly tested by a qualified
electrician. The manufacturer cannot be held
responsible for the consequences of an inadequate earthing system.
Do not use a machine with damaged con-
trols or damaged cables. These must be
repaired before it is used again.
During the cleaning programme the tank
is rinsed out with hot water. Ensure that
no personnel touch the tank and the filter unit
while it is still hot. They could burn themselves.

Cleaning and Care
Carry out cleaning and care of the unit as
soon as possible after use. Cleaning must
not be carried out during a wash programme.
Do not use a high pressure cleaner.
Before each wash cycle check the fluff filter
for fluff build-up and clean if necessary.
Cleaning programme
If use of the unit is to be or has just been discontinued for some time, there is a cleaning
programme available for this circumstance.
Before starting the cleaning programme,
clean the fluff filter and filter unit as described
below.
Remove any fluff and dirt from the filter
unit, the filter and the pump and rinse out
with water.
➧
For cleaning the water must first be let out
of the filter unit. To do this pull out the
stopper in the filter unit.
Refit the stopper.
Start the WRG cleaning programme.
At the end of the programme pull out the
stopper again to let the water out of the filter unit, and if necessary clean the fluff filter once again.
7 M.-Nr. 04809250
Cleaning and care
Cleaning the tank
From time to time the tank must be opened
and checked for dirt.
Start the WRG emptying programme.
At the end of the emptying programme
loosen the tension band at the top edge of
the tank with an SW 13 screwdriver.
Repairs to machines should only be under-
taken by a suitably qualified service engineer
to ensure safety. Unauthorized repairs could
be dangerous. Please contact the Service
Department in cases of malfunction.
Service Department needs model, machine
number (N°) and part number (TN).
This data is on the data plate.
Components should only be exchanged
for Miele original spare parts. In this case
Spare Parts Department also needs the
model, machine number (N°) and part num-
ber (TN).
Lift the lid.
Use a brush to remove any stubborn dirt.
Refit the lid and then start the cleaning programme.
The tank and the filter unit are made of stainless steel. However water with an iron content or foreign bodies in the water can lead to
rust deposits especially if the unit is out of use
for some time. In this case clean the tank
and filter unit with a gentle domestic scouring
agent.
Rinse thoroughly with water afterwards.
