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 25th 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

sideofthe rearpanel,bothtransit 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 installed, 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 standpipe.

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.
