							Installation surface
A concrete floor is the most suitable
installation surface for a washing
machine, being far less prone to
vibration during the spin cycle than
wooden floorboards or a carpeted
surface.
Please note the following points:
The machine must be level and
securely positioned.
To avoid vibrations during spinning,
the machine should not be installed
on soft floor coverings.
If installing on a wooden joist floor:
We recommend a plywood base
(at least 59x52x3 cm). The base
should span several joists and be
bolted to the joists and not only to the
floorboards. Check for the presence
of pipes and cables.
If possible, install the machine in a
corner, as this is usually the most stable
part of the floor.
If the machine is installed on a
raised plinth, ithas to be secured
against slippage during spinning
using retaining clips (available from
the Miele Spare Parts Dept).Installing the washing machine
To manoeuvre the machine out of its
packing case to its installation site hold
it by the edge of the lid where it
protrudes to the rear of the washing
machine as well as by the handle
recesses at the front.
Ensure that the machine feet and
the floor are dry to prevent the
machine from slipping during the
spin cycle.
Removing the transit bars

To remove the left and right covers
1. Use a screwdriver to prise out the
cover as illustrated.
2. Pull the cover forwards to remove.

							To avoid the risk of injury the
holes for the transit bars must be
covered after the transit bars have
been removed.
Fit the covers on to the two holes.
Then plug the holes as shown with
the caps.Secure the transit bars to the back of
the washing machine. Make sure that
holesare fitted over retainers.
The washing machine must not
be moved without the transit bars in
place.
Store the transit bars as shown or
keep them in a safe place for future
use. They must be re-fitted if the
machine is to be moved again
(e.g.when moving house).
Re-fitting the transit bars
Re-fitting is carried out by reversing the
procedure.

							Levelling the machine
The machine must stand perfectly level
on all four feet to ensure safe and
proper operation.
Incorrect installation may increase
electricity and water consumption and
may cause the machine to move about.
Screwing out and adjusting the feet
The four adjustable screw feet are used
to level the machine. All four feet are
screwed in when the machine is
delivered.

Using the spanner supplied turn
counter nut2in a clockwise
direction. Then turn counter nut2
together with foot1to unscrew.Use a spirit level to check the
machine is standing level.
Hold foot1securely with a pipe
wrench. Turn counter nut2again
using the spanner supplied until it
sits firmly up against the housing.
All four counternuts must be
firmly up against the housing. Please
also check this for the feet which did
not need adjustment. Otherwise
there is the danger of the machine
moving about.

							The fitting of building under kits and
stacking kits must only be
undertaken by qualified and
competent persons, in accordance
with the instructions supplied with
the kit.
Building under a continuous
worktop/in a kitchen run
If you wish to push your machine under
a worktop and there is space to do this
without removing the lid, the
conversion kit is not necessary.
Otherwise the conversion kit is
essential.
– A special building under conversion
kit* is required.
To ensure electrical safety, the
washing machine lid must be
replaced by the cover plate supplied
with the conversion kit.
– For installation under a work surface
900/910 mm from the floor, a raising
kit* is required.
–
Connections for electricity, water and
drainage should be installed in such
a way that they remain accessible
when the machine is in place.
Fitting instructions are supplied with the
conversion kit.
All parts marked* are available from
your Dealer or the Miele Spare Parts
Department.Washer and Dryer stack
A Miele tumble dryer can be stacked
with the washing machine. A WTV
stacking kit* is necessary and can be
purchased from the Miele Spare Parts
Department or via the internet at
www.miele-shop.com.
Please note:
aSafety distance to wall:
at least 2 cm
bHeight:
Stacking kit with pull-out shelf:
approx. 169 cm
Stacking kit without pull-out shelf:
approx. 170 cm
Replacing the lid
If the lid has been removed in order to
fit a stacking kit or cover plate, ensure
that, if the lid is replaced, it fits securely
into the rear holders. Otherwise, it is not
properly secure for transport.

							The Miele water protection
system
The Miele water protection system
protects the washing machine from
water damage.
The system consists of three main
components:
1) the inlet hose
2) the electronic unit and the washing
machine housing
3) the drain hose
1) Inlet hose
The inlet hose can withstand
pressure of more than 7,000 kPa.
2) Electronic unit and washing
machine housing
– Sump
Any leaking water is collected in a
sump in the base of the machine. A
float switches off the safety valves,
preventing any more water flowing
into the machine and water in the
suds container is pumped away.–Overflow protection
This prevents the washing machine
taking in too much water. If the water
level exceeds a certain level, the
drain pump switches in and pumps
the excess water away.
3) Drain hose
The drain hose is protected by a
ventilation system which prevents the
washing machine from being
emptied completely.
Installation and connection
49
 
						

							Connection to the water
supply
The machine should be connected to a
mains water supply in accordance with
local and national safety regulations.
The German authorities do not require it
to have a non-return valve as the
washing machine has been designed
to comply with DIN regulations.
The machine is designed to operate
with a flow pressure of between
100 kPa and 1,000 kPa. If it is higher
than 1,000 kPa it is essential to fit a
pressure reducing valve.
Connection to the mains water supply
should incorporate a mains stopcock
with
3/4 thread. The stopcock should
be fitted by a qualified plumber.
The connection point is subject
to mains water pressure. Turn on the
stopcock slowly and check for leaks.
Correct the position of the washer
and union if appropriate.
The washing machine isnotsuitable
for connection to a hot water supply
and connection to a household
water softener is not recommended.
Maintenance and care
Only use a genuine Miele hose should
you ever need a replacement or
extension. These are tested to
withstand pressure of at least
7,000 kPa.
In order to protect the water inlet
valve, the two dirt filters - one in the
open end of the inlet hose, one at
the inlet point in the machine must
not be removed.
Extension hose
–Longer hoses 2.5 or 4.0 m in length
are available from your Miele dealer
or the Miele Spare Parts Department
as optional extras.
