DEVELOPMENT HISTORY
September 2004 Date Code 33 Aquarius versions WD420 enter full production.
November 2004 Date Code 35 WD440P - General tactical model, same as WD420 but with 1400 rpm spin.
February 2005 Date Code 38 WD440G first produced.
April 2005 Models WD420 & WD440 Date Code 40 Change to Cold Fill and deletion of heater box fluff filter.
On 25
th
April 2005 (Date Code 40), this range of washer dryers changed from Hot and Cold Fill to Cold Fill only. Along with this change a modification was made to the tumble dryer heater box assembly with the introduction of a straight heating element, this to improve the air flow through the heater box. This change enables the removal of the heater box fluff filter and deletion of the flushing valve and hose. The thermistor, one-shot cut out and fan assembly are not affected. The 4-way valve is replaced by a 3-way valve and the hot supply hose is deleted.
A new file setting (EEPROM) is used for cold fill machines, but the consumer programmes remain the same for both Hot and Cold and Cold fill machines. The changes to the heater box assembly does not effect the EEPROM file settings.
May 2006 Model WD420 & WD440 (S/N 60508.0000) Re-introduction of flushing valve style heater box assembly.
On 8 May 2006 (S/N 60508.0000), the flushing valve and fluff filter was re-introduced in production, along with spiral element, metal fan, externally mounted dryer motor and thermal fuse cable, which is attached to the heater box upper casing in place of the one shot cut-out device.

INSTALLATION
Unpacking
1. Unpack the washing machine.
2. Check whether the washing machine has been damaged during transport. If this is the case, do not install it.
Remove the polystyrene base
The vertical block part of the base (see below) should have stayed intact when the base was removed. If it has broken off and is still inside the machine, carefully lay the machine on its side, onto the polystyrene top cap and then remove the block.
Warning:
Packaging materials are not childrens toys.
Remove the transit fixings
Follow these instructions to remove the TWO transit fixings. IMPORTANT: Situated one either side of the rear panel, both transit bolts (complete with spacers) MUST be removed before use.
Failure to do so may cause damage to the machine!
1. Use a crosshead screwdriver to remove the plastic cover.
Vertical block
polystyrene base
For safety, replace both plastic covers over the holes left by removing the two bolts.
Levelling
1. Install the washing machine on a flat sturdy floor, without resting it up against walls, cabinets etc.
2. Compensate for any unevenness by tightening or loosening the adjustable front feet. The angle of inclination, measured according to the worktop must not exceed 2°.
Levelling the appliance correctly will provide it with stability and avoid any vibrations, noise and shifting during operation. If it is placed on a fitted or loose carpet, adjust the feet in such a way as to allow enough room for ventilation beneath the washing machine.
2. Unscrew the bolt using a 13 mm spanner.
3. STOP when 3 threads can be seen.
4. Hold, slide and pull to remove.
! It is important the transit bolt and spacer come out intact
(see image left).

Connecting to the Water Supply
WARNINGS: The temperature of the hot water supply should ideally be 60°C and no higher than 70°C as this could cause damage to the laundry and the machine. Applies to
products produced prior to Date Code 40.
Do not connect the machine to a single outlet instantaneous water heater.
The hot and cold water pressure should be between 3 and 150 psi (21 - 1034 kPa). Incorrect pressures could lead to flooding.
The water supply taps should be accessible when the machine is installed.
Before connecting the fill hoses, check that water is running from the water supply taps you will use for the machine.
Connect the washing machine to the water supply using the fill hoses fitted to the machine.
Do not use old hoses.
Hot & Cold Fill - Cold fill only from D.C. 40
1 Unclip the grey and blue fill hoses from
the back of the machine.
2 Connect the free end of the grey fill hose
to the HOT water supply (see figure1). Connect the free end of the blue fill hose to the COLD water supply.
3 Turn on the water supply and check for
leaks. If there is a leak, turn off the water supply, remove the connector and check that the sealing washer is in place.
Refit the connector and tighten it. Turn on the water supply.
4 When moving the machine into its final
position, make sure that the hoses are not trapped or kinked.
Fig. 1 Fig. 2
If the fill hoses are too short:
Longer fill hoses are available. Remove the existing fill hoses from the inlet valves on the back of the machine and fit the new longer fill hoses as shown above with the angled ends of the hoses connected to the machine (see Fig. 2).
If no hot water supply is available or the hot water pressure is low, a cold fill adaptor (Fig. 3) and fitting instructions are available.
Applies to products produced prior to D.C. 40.
Electrical connections
Before plugging the appliance into the mains socket, make sure that:
- the socket is earthed and in compliance with the applicable law.
- the supply voltage is included within the values indicated in the Specifications page.
- the socket is compatible with the washing machines plug. If this is not the case, replace the socket or the plug.
Location
! The washing machine should not be
installed in an outdoor environment, not even when the area is sheltered, because it may be very dangerous to leave it exposed to rain and thunderstorms.
! When the washing machine is installe d, the
mains socket must be within easy reach. ! Do not use extensions or multiple sockets. ! The power supply cable must never be
bent or dangerously compressed. ! The power supply cable must only be
replaced by an authorised engineer.

Drainage Connections
Take care when you remove the drain hose from the clips on the back of the machine. All machines are tested with water before they leave the factory so a small amount of water may still be in the hose.
Do not remove the hooked end support from the GREY drainage hose when using any of the drainage methods detailed below. You may need to reposition it as required along the drainage hose.
For drainage into a standard work top sink, ensure the outlet pipe has a minimum diameter of 32 mm. If the sink is inset, the front edge of the basin must be less than 75 mm from the front edge of the worktop, so that the drain hose will hook securely into the sink.
Unclip the drainage hose from the back of the machine and hook over into the sink. Make sure that the sink is free of any obstructions and that the sink plug can not fall into the sink, preventing the water from draining away freely. Pumped out water may be very hot.
We recommend one of the following drainage methods:
Stand pipe Fig. 1 1 Make sure that the
standpipe has a minimum diameter of 38 mm.
2 Remove the
drainage hose from the clips on the back of the machine.
3 Make sure that the
top of the standpipe is positioned at least 500 mm from the floor (see Fig.1).
Use the plumbing indicator line label on the back of the machine as a guide.
4 Place the drainage hose approximately
100 mm into the standp ipe.
500 mm
Extending the drainage hose
If the GREY drainage hose is too short, a longer drainage hose is available from our Genuine Parts & Accessories Mail Order Hotline.
WARNING!
The company denies all liability if and when these warnings are not respected.
The first wash cycle
Once the appliance has been installed and before you use it for the first time, run a wash cycle without detergent and no laundry, setting the 90°C programme without a pre-wash cycle.
Under Sink Waste System

Fig.3
1 Cut out the
membrane, bung or blanking plug (see Fig. 2).
2 Unclip the drainage
hose from the back of the machine.
3 Move the hooked
end support along the drainage hose as required.
4 Attach the drainage
hose securely to the under sink drainage unit, using a hose clip (see Fig. 3).
5 Raise the hooked
end support up to at least 800 mm to avoid water being drawn back into the machine.
