3 TECHNICAL OVERVIEW
This Service Manual contains information on the Product Specifications, Diagnostic Mode, Detailed
Fault Codes and the complete disassembly and assembly instructions for the washing machine.
3.1 Electronics
3.1.1 Motor Control Module
The Motor Control microprocessor performs a wide variety of tasks. Primarily it controls the
electronic switching hardware to control the three phase currents in the Smart Drive DC motor.
The micro can accurately control not only the velocity of the motor but also the acceleration. This
accurate control is required to perform all the different agitator profiles, or wash actions, that are
used for caring for clothes. The Motor Control module performs the functions of fill, wash, drain
spray rinse and spin, when commanded to by the Display.
The Motor Control module microprocessor has a wide range of control with great accuracy over
water level, fill temperature, agitate action and spin speed. Having such control insures the wash
cycle selected provides the optimum soil removal combined with appropriate gentleness for the
washing and care of the clothes load.
The Motor Control Module for this Washer is air-cooled.
This Motor Control Module is not inter-changeable with other any other Series of machine.
Identification
The Motor Control module has an identification label attached to the top of the housing stating
P9NECO (Phase 9, Conventional Pump Non Eco) and P9ECO (Phase 9, Conventional Pump Eco)
Motor Control Module
Note: When replacing a Motor Control Module ensure that the pressure tube is clear of any
water droplets before operating the machine on a fill cycle. If the bowl is full of water drain
the water then blow down the tube before reconnecting the pressure tube.
Ensure you have checked the resistance of all components going to the controller such as
pump, water valves, etc. otherwise controller will short and fail.

421827
12
3.1.2 Display Module
The Display Module provides the link between
the washing machine electronics and the user.
Input on wash type, water level, spin speed,
start/stop and wash cycle time is given by the
user via the display push buttons.
Feedback on selection is given to the user by
LCD liquid crystal displays or Light Emitting
Diodes (LEDs) depending on model. Sound
effects accompany button presses.
IW Display
GW / WA & MW Display
3.2 Stand By Mode
If the machine has not received any instructions it will automatically go into a low power “Stand By”
mode. The control panel will be blank as if it was powered off at the wall. “Stand By” happens after
a period of 10 minutes for MW, GW & WA machines and 2 minutes for the IW.
Before entering the Diagnostic or Option Adjustment modes, the machine must be taken out of the
Stand-By mode. To do this, the POWER button will have to be pressed, or the machine turned off
and back on at the mains supply point.
3.3 Out of Balance Detection – ‘Bump Detect’
On this machine the Out of Balance detection, is undertaken with electronic sensing, known as
‘Bump Detect’. ‘Bump Detect’ is software written into the Motor Control Module, which looks at
specific feedback from the Motor.
No fault codes are associated with ‘Bump Detect’, and there are no hard and fast tests that can be
carried out.
If a machine continually goes into an out of balance condition then the following needs checking in
the order given.
1. Even distribution of the wash load.
2. Ensure that the corner cabs are clear of the floor & machine is sitting on its feet.
3. Ensure that the machine is both level and stable on the floor with feet inserts fitted.
4. Check the bias spring is fitted and attached.
5. Check the weight of the inner bowl. Bowl weights are as follows:
Compact: 7.30kg +/- 225g
Medium: 8.37kg +/- 225g
Large: 10.48kg +/- 275g.
Note: If the OOB problem persists after checking the above, we would then recommend
replacing both the suspension rods and the rotor. It is highly unlikely that the Motor
Control Module will be the cause.

421827

3.4 Water Temperature Sensing
WashSmart, GW, WA & FabricSmart, IW Machines
The thermistor for sensing water temperature is
located in the back of the outlet elbow on the
valve assembly, and is connected directly to the
Motor Control Module.
For details on the wash temperature adjustment
Refer to the Use & Care manual.
Specifications
NTC-type temperature sensor (Thermistor)
Resistance 10KΩ@ 25oC.
QuickSmart, MW Machines
As there is no thermistor (temperature sensor) in this Washer the only temperature that can be
adjusted is the warm wash temperature. The temperature of the warm wash is entirely dependent
on a number of factors:
a. Cold water temperature
b. Cold water pressure
c. Hot water temperature
d. Hot water pressure.
e. Warm wash setting.
As the above will vary from installation to installation it would be impossible to predict what
temperature each installation will ultimately achieve.
However under the conditions outlined below, a temperature of between 36–38oC should be
achieved.
Cold water temperature: 20 oC
Cold water pressure: 320 kPa (46.5 psi)
Hot water temperature: 60 oC
Hot water pressure: 320 kPa (46.5 psi)
Warm wash setting: Default setting (9 min wash LED – 3rd Green wash LED from the left).
3.4.1 Warm Wash Temperature Adjustment (QuickSmart MW Only)
The warm wash temperature adjustment will alter the amount of time that the hot valve pulses on
and off for.
1. Turn the machine on at the wall but of at the console.
2. Press and hold down the START/PAUSE button, then press the POWER. Two quick beeps will
be heard and the machine will show an unusual pattern of lights. In this mode the lights are
used to indicate the different options available.
3. Select the Warm Wash Temperature.
4. Advancing the Wash Progress LED by pressing the ADVANCE button will increase the wash
temperature. If the ADVANCE button is continually pressed, the light will scroll back to the
coldest setting available for that wash temperature.
5. Press the POWER to ‘lock’ in the setting.

Note:
If the required temperature still can’t be obtained, advance the wash progress LED (as
described in the procedure above) across to the spin LED and manually adjust the flow of
the taps.
3.4.2 Wash Temperature Adjustment (WashSmart, WA Only)
1. Turn the machine on at the wall but of at the console.
2. Press and hold down the START/PAUSE button, then press the POWER. Two quick beeps
will be heard and the machine will show an unusual pattern of lights. In this mode the lights are
used to indicate the different options available.
3. Use the Wash Temp buttons to select the WASH TEMPERATURE to be adjusted.
4. The wash progress lights show the temperature adjustment possible for that temperature.
Pressing the ADVANCE will cause the wash progress light that is on to change. Advancing the
Wash Progress light will increase the wash temperature. If the ADVANCE button is kept
pressed, the light will scroll back to the coldest setting available for that wash temperature
3.4.3 Controlled Cold (WashSmart, WA Only)
If the cold water inlet temperature is very low (below 20oC), an effective wash will not be obtained.
The controlled cold option solves this problem by adding a small amount of hot water to raise the
temperature of the wash. We have called this ‘Controlled Cold’.
1. Turn machine on at the wall but do not press POWER.
2. Press and hold down the START/PAUSE button, then press POWER. Two quick beeps will be
heard and the machine will show an unusual pattern of lights. In this mode the lights are used
to indicate the different options available.
3. Use the Wash Temp buttons to select the COLD wash temperature.
4. The Wash Progress lights show the temperature adjustment possible. When the first progress
light is on, the machine will fill with cold tap water only. Press ADVANCE to select the second
light and the SmartDrivewill control the temperature to approximately 20°C. Each following
light equals approximately a 1°C temperature rise.

421827
15
3.4.4 Wash Temperature Adjustment (FabricSmart, IW Only)
1. Turn machine on at the wall and touch
the POWER button.
2. Touch the Lifestyles/Options
button noting that OPTIONS is
highlight, and then use the Scroll
arrows or to highlight

3. Highlight the temperature required using
the Scroll arrows or then confirm
with the select button to set the
temperature.
4. If the temperature is to be permanently
programmed, when the “Save for Future
Washes” screen appears, confirm YES
with the Select .
3.5 Water Valves
The machine uses a dual valve block assembly.
Independent coils control the hot and cold water
supply, which feeds the water through a
common outlet.
The WashSmart, FabricSmart, GW, WA & IW
valve block has a location feature for the
thermistor. There is no thermistor location
feature on the QuickSmart, MW Washer.

421827
16
3.6 Diverter Valve (FabricSmart, IW Only)
The Diverter Valve is situated at the bottom of
the outer bowl beside the Pump. It consist of a
wax solenoid which heats up and moves a
flapper to close off the drain enabling the water
to be diverted back into the inner bowl, with the
pump running. When powered on there is 160
volts DC across the terminals.
NB: The Valve takes approximately 1 minute
to activate and 3 minutes to cool down and
return to its normal position.
3.7 Water Level Measurement
The machine is fitted with a pressure sensor, which can control the fill to any water level. The
pressure sensor is incorporated within the Motor Control Module and cannot be removed. The
pressure tube connects from the Motor Control Module to the air bell at the bottom of the outer
bowl, and is part of the harness assembly. Care must be taken when removing or refitting the
pressure tube to the pressure sensor as too much force can damage this device.
3.7.1 Manual Water Level (QuickSmart & WashSmart, MW, GW & WA)
The agitator has 5 levels marked on its stem that can be used to help the user select the correct
water level. Select the correct water level by using the mark nearest to the top of the clothes.
The levels marked on the agitator are a guide for the clothes and do not correspond exactly to the
water level.
Occasionally water may be added during agitation. This is to maintain the water level due to the
release of air trapped in the garments.
For example: If the garments sat between the medium and high marks on the agitator, choosing a
medium water level would be better than choosing a high water level. Alternatively additional
garments could be added so that the garments were brought closer to the high mark.

Water Level Settings
Tolerance for each water level = +/- 15mm
3.7.2 Auto Water Level (WashSmart, GW, WA Models)
The machine automatically selects the appropriate water level for the load when AUTO Water
Level is selected, and will choose one of the pre-existing 5 water levels (low, medium low, medium,
medium high and high). During fill the machine pauses occasionally to sense the water level. The
machine checks if the water level is correct by using a series of 2 different agitate strokes. A slow
stroke to sense the load and an agitate stroke to mix the load. If the machine detects that the
water level is too low it will fill with more water and check the level again.
When washing an unusual load, e.g. large bulky garments, pillows, it is recommended that the
water level is manually selected.
Manually select the water level if there is already water in the bowl.
If the machine does not fill to the correct level, the auto water level can be adjusted in the Option
Adjustment Mode. Refer to the Use & Care manual for the various options adjustments available.
To enter the option adjustment mode:
1. Plug the machine in but do not press the POWER.
2. Press and hold the Start / Pause button, then press Power
3. Three quick beeps will be heard and the machine will show an unusual pattern of lights.
4. Carry out any option adjustments necessary.
5. Press the POWER button to return to the normal mode.

3.8.1 Stator
The stator used is not interchangeable with any previous phase or series of machine. This stator
has 36 poles with the windings being Aluminium and is Identified by the printed marking AL 60
190T it looks the same as a copper Stator but is 19.5per winding.

Testing the Stator
If the stator needs to be tested we would first recommend testing the resistance of the windings at
the harness that is connected to the Motor Control Module. (Refer to Section 5.9).
Note: Ensure that the Rotor and bowl are stationary when measurements are made.
Testing the stator from the console
The resistance of each individual winding is approximately 19.5, however when testing the stator
from the console we are testing across two windings therefore the resistance should be
approximately. 39+/- 10%
To test all windings you will need to measure across:
Red & Blue
Red & Yellow
Blue & Yellow
If the meter shows an incorrect reading we would then recommend testing the stator from
underneath the machine as there could be a fault in the wiring harness. To test the stator, remove
the rotor and stator. Refer to Sections 8.19 and 8.20.
Note: Two clamp plates are used to secure the Stator, one on each side. The four bolts are
tightened to a torque of 5-7Nm. The plastic bolt for securing the Rotor requires a 16mm
socket and should be tightened to 8-10Nm.

Testing the Stator
After removing the Stator, it can now be tested.
Test points are:
R (Red) / B (Blue)
B (Blue) / Y (Yellow)
Y (Yellow) / R (Red)
The value should be approx. 39+/- 10%
across any of the two windings.
3.8.2 Rotor
The rotor is also unique to this machine. It has 48 blocks of individual magnets in a black
moulding.
The rotor is not interchangeable with any previous phase or series of machine.
The rotor can physically be interchanged, however electrically they are incompatible.
The photograph below shows the Rotor used.

3.9 Pumps
Blocked Pump Detection
This is achieved by monitoring the water level during drain. If the water level has not dropped by
approximately 3mm within a predetermined time period (approximately 9-10 minutes), then the
product will report a pump fault.
3.9.1 Selni
The pump is coupled directly to the outer bowl.
This eliminates tub to pump hoses and the
accompanying seals, clamps etc. The pump
housing is an integral part of the outer tub.
When removing the pump up to a litre of water
may leak from the pump cavity. When refitting
the pump; lubricate the seal face with liquid
soap or detergent (do not use grease).
Note: The Resistance of the pump should
read 33Ω+/- 8%. (Refer to section 2.6)
3.9.2 Hanning
This pump is an asynchronous pump that will
start randomly in either direction.
The pump comes with its own bracket which is
mounted to the outer bowl by three screws.
This configuration requires a tub to pump hose
in the form of an elbow and accompanying
hose clips
When removing the pump up to a litre of water
may leak from the pump cavity.
Note: The Resistance of the pump should read 93Ω+/- 8%. (Refer to section 2.6)
3.10 Lid Lock
All washers use a lid lock to secure the lid closed, which is
locked during the spin and drain out part of the cycle, prior to
spray rinse the lid will lock down until the completion of the
spin.
When locked on the QuickSmart, WashSmart, MW, GW &
WA machines the “Lid Locked” LED will illuminate. Once the
spin has completed, the lock will release and the lid can be
opened. To open the lid during the cycle, while the LED is
illuminated press the START/PAUSE button, the machine
will come to a halt, and the lid locked LED will extinguish.
If the lid is left open, the machine will be unable to lock the lid
and the cycle will be halted. The machine will play a tune
and the lid lock will flash until the lid is closed and the
START/PAUSE button is pressed.
