2.0 Installation
 The Shipping Struts must be completely removed prior to any
operation and / or testing.
 Ensure the appliance is being installed on a suitable surface.
 Chlorine Bleach is not recommended.
 Only detergent carrying an “H.E.” (High Efficiency) designation should
be used.
 The appliance comes equipped to operate using only powder
detergent; to use liquid detergents an optional detergent drawer insert
is required - call Miele Technical Support to order.
 The machine must be perfectly level to ensure safe and proper
operation.
 To perform a stacked installation an approved Miele Stacking Kit that
matches the exact model numbers must be used. The washer must
be the lower appliance and installed first.
Note:
A Laundry Stand and a Stacking Kit cannot be used together.
2.1 Electrical Requirements
 120/240 (208) Volt, 60Hz., 15 Amp breaker
Washers are equipped with a 4 wire power cord consisting of L1, L2,
N and Ground; equipped with a NEMA 14-30 plug, for connection to a
NEMA 14-30 receptacle.
Note:
For proper appliance operation a Neutral is required.
Note:
If you do not have a dedicated 15 Amp circuit for this appliance, but have
a NEMA 14-20 or NEMA 14-30, 240V, 30 Amp outlet, you may be able to
use a Miele “Easy Installation Kit” to simplify the electrical connection.
For further information refer to Electrical Information pages in the
Installation Manual.
 Do not cutoff / remove the plug from the power cord.

2.2 Plumbing Requirements
Water Inlet
All W1900 series washer (except the W1903) are equipped with two
Water Inlet Hoses. Connect the Cold Water Intake Hose (blue mark)
to the Cold Water Valve and the Hot Water Intake Hose (red mark) to
the Hot Water Valve.
 The W1903 is equipped with a single Inlet Hose; that must be
connected to a cold water supply.
 The water pressure must be within 15-145 psi (1-10 bar). If the water
pressure is greater than 145 psi (10 bar), a Pressure Reducer must
be installed. If the water pressure is below 15 psi (1 bar), insufficient
water may be available for a complete fill. The Water Intake Hoses
are equipped with Screen Filters - do not remove these filters.
Note:
For customers requesting a “cold water only connection” on washers
equipped with Dual Inlet Hoses a “Y” adapter (available at most hardware
stores) can be utilized. Both Inlet Hoses (hot and cold) should be
connected to the adapter.
Drain Connection
The appliance is equipped with a 5 ft. (1.5 m) drain hose with a maximum
delivery height of 4ft. (1.2 m) which can be connected as follows:
1. Directly into a sink: hook the hose over the edge of the sink and
secure it firmly (i.e. by tying the hose to the water faucet etc...).
2. To a stand pipe: place the Drain Hose into a 1 1 /2" (38 mm) stand
pipe and secure in place.
3. To a floor drain: The machine is equipped with an Airgap/Anti-
Siphoning System so that no minimum drain height is required.
Important!
Ensure all connections are secure & hoses are free from sharp bends
and kinks.

2.3 Installation Procedure
1. Lift the machine from the shipping pallet and move it to the installation
site. Do not lift the machine by the Drum Door.
Note:
Ensure that the machine feet and the floor are dry to prevent slippage
during the spin cycle.
2. REMOVE THE SHIPPING STRUTS - by performing the following:
 Turn the left Shipping Strut 90° counterclockwise
Figure 2-1: Turning the left Shipping Strut Counter Clockwise.
 Turn the right Shipping Strut 90° clockwise.
Figure 2-2: Turning the right Shipping Strut Clockwise.
