2 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 Phase 7 washing
machines.
2.1 Electronics
2.1.1 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 spin, fill, wash,
drain and spray rinse when commanded to by the Display.
The Motor Control module microprocessor has a wide range of control with great accuracy over
spin speed, agitate action, fill temperature and water level. 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 Modules for the Phase 7 Washers are air-cooled in the same way as the Phase
5, and 6 machines are, and are colored brown, the same color that is used for Phase 6, Series 11
& 12 machines.
This Motor Control Module is not inter-changeable with other any other Phase or Series of
machines.
Identification
The physical shape of the Motor Control Module is different to the Phase 6 machines. The Phase
7 module also has a yellow label attached to the top of the housing stating P7CP (Phase 7,
Conventional Pump).

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 basket is full of water
drain the water then blow down the tube.
517792A
10
2.1.2 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
Light Emitting Diodes (LEDs). Sound effects
accompany button presses.
2.2 Stand By Mode
If a Phase 7 machine has not received any instructions for 10 minutes after being switched on at
the power point, or after completing the cycle, 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.
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 power point.
2.3 Out of Balance Detection – ‘Bump Detect’
Past electronic machines have used a lever connected to a mechanical switch to detect if the load
in the inner basket is out of balance. On Phase 7 machines this system has been replaced with
electronic sensing known as ‘Bump Detect’. ‘Bump Detect’ is software written into the Motor
Control Module, which looks at specific feedback from the Rotor Position Sensor.
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 to be
checked in the order given.
1. Even distribution of the clothes load.
2. Ensure that the machine is both level and stable on the floor.
3. Check the weight of the inner basket (23.10 +/- 9.7oz / 10.480kg +/- 275g).
4. Check the RPS using a RPS Tester.
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.

2.4 Water Temperature Sensing
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 Section 2.4.1 & 2.4.2.

2.4.1 Wash Temperature Adjustment
1. Turn machine on at the wall but do not press POWER.
2. Press START/PAUSE and hold down, 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. 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
2.4.2 Controlled Cold
If the cold water temperature is very low (below 68 oF / 20 oC), a very 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 START/PAUSE and hold down, 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. Select 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 water only. Press ADVANCE to select the second light
and the EcoSmart
â
will control the temperature to approximately 68 oF / 20 oC . Each following
light equals approximately a 33.8
o
F / 1°C temperature rise.

2.5 Water Valves
The Phase 7 machines use a new dual valve
block assembly. Independent coils control the
hot and cold water supply, which feeds the
water through a common outlet.
The valve block has a location feature for the
thermistor.
2.6 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
basket, 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.
517792A
13
2.6.1 Manual Water Level
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.
EcoSmartÒ Water Level Settings
Tolerance for each water level = +/- .59in / 15mm
2.6.2 Auto Water Level
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 that
water level is too low it will fill with more water and check the level again.
· When washing an unusual load eg. large bulky garments, pillows, it is recommend that the
water level is manually selected.
· Manually select the water level if there is already water in the basket.
If the machine does not fill to the correct level, the auto water level can be adjusted in the Option
Adjustment Mode.

2.7 Motor
2.7.1 Stator
This stator used on the Phase 7 machines are unique to this phase only and therefore it is not
interchangeable with any previous phase or series of machines. The stator has 36 poles instead
of 42 poles, and the pole tips are curved. The resistance of the windings remains the same as for
the Phase 5, Series 9, and Phase 6, Series 11 and 12 machines at 16W per winding. The rotor
position sensor is also unique to this stator. (Refer to Section 2.7.3.)

2.7.1.1 Testing the Stator
If the stator needs to be tested we would first recommend testing the resistance of the windings
from the harness that is connected to the Motor Control Module. (Refer to Section 7).
Note: Ensure that the Rotor or basket is stationary when measurements are made.
Testing the stator from the console
The resistance of each individual winding is approximately 16W, however when testing the stator
from the console we are testing across two windings therefore the resistance should be approx.
32W +/- 10%.
To test all windings you will need to measure across:
· Red & Blue
· Red & Yellow
· Blue & Yellow
517792A
15
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, both
rotor and stator need to be removed. Refer to Sections 9.16 and 9.17.
Note: Two clamp plates are used to secure the Stator, one on each side. The four bolts are
tightened to a torque of 5Nm. The plastic bolt for securing the Rotor requires a 16mm
socket and should be tightened to 8Nm.
Testing the Stator
After removing the Stator, it can now be tested.
Test points are:
Red / Blue
Red / Yellow
Blue / Yellow
The value should be approx. 32W +/- 10%
across any of the two windings.
2.7.2 Rotor
The rotor is also unique to the Phase 7 machines. It has 16 blocks containing 3 individual
magnets, as opposed to 14 blocks, containing 4 magnets for Phase 5, and Phase 6 machines.
The rotors between Phase 7 and previous Phases of machines can physically be interchanged,
however electrically they are incompatible.
If a Phase 7 rotor is fitted to a Phase 6 or earlier machine, fault code 240 will occur. Conversely
fault code 240 will also occur if a rotor from a Phase 6 or earlier machine is fitted to a Phase 7
machine.
Apart from the number of magnets the other (and easiest) way to identify the Phase 7 rotor is by
the number of holes. The Phase 7 rotor has larger holes around the outer perimeter and an
additional set of large holes on the inner perimeter.
The photographs below show the difference between a Phase 7, and a Phase 6 Rotor.

2.7.3 Rotor Position Sensor (RPS)
One of the inputs that the Motor Control Module needs in order to determine which switches to turn
on is the position of the rotor. The rotor position sensor (RPS) supplies this information.
The RPS is a printed circuit board that contains
three Hall Sensors. These detect the magnetic
field of the individual magnets in the rotor. As
the motor turns, the position of a group of
magnets is detected. There are 5 wires on the
RPS, 2 for power supply and 3 signal wires.
Data on the position of the rotor is supplied to
the microprocessor in the Motor Control Module
via the three signal wires.
The printed circuit board sits in a plastic housing
encapsulated by resin to protect the board. The
only exposed area of the board is the connector
for the main harness.
2.7.3.1 Testing the Rotor Position Sensor
To test the RPS use a RPS tester, part number 502105, which is powered by a 9V battery. To test
the RPS of a Phase 7 Washer it will also require an adaptor harness, part number 420892. The
tester has 3 LEDs, and the pattern of these LEDs will change as the magnetic field of the Rotor
passes the hall sensors.
Connect the RPS tester to the RPS harness. Turn the basket and note the pattern of lights. A
valid pattern is a pass. A fail will indicate a failure of either the harness or the RPS. If a failed
pattern is showing, connect the RPS tester directly on to the RPS and retest.
A pass is when 1 or 2 LEDs are illuminated at a
time, 0 or 3 LEDs illuminated indicates fail. Any
flickering of the fail LED will indicate that the
RPS or rotor is faulty. A faulty rotor would give
a fail at certain points of rotation.
Note: This tester does not test all the functionality of the RPS. It tests the 3 outputs but
cannot indicate all faults, for example if a capacitor on the RPS is cracked.
The rotor may also be tested with a RPS Tester. A complete rotation will test all the magnets.
If the rotor has cracked or chipped magnets it will work fine, and does not need to be replaced.
517792A
17
2.8 Pump
The pump is coupled directly to the outer
basket. This eliminates basket to pump hoses
and the accompanying seals, clips etc. The
pump housing is an integral part of the outer
basket.
When removing the pump up to a liter 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).
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 blocked pump fault.
2.9 Lid Lock
The Phase 7 Washer uses the same lid lock that is used on
the Phase 6 series 11 & 12 machines. The difference being
is that the lid is now locked for the entire cycle. When the lid
is locked 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 the
START/PAUSE button must be pressed, 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
START/PAUSE is pressed.
· If the lid-lock fails in the closed position, the locked lid can be forced upwards and out of the
lock. Note: This is the only time in which we would recommend doing this.
· If the harness is damaged, the complete lid lock assembly will need to be replaced.
If the power supply is cut during the spin cycle, the machine will keep the lid locked until the rotor
has ceased to turn (3 to 10 secs). Only then will it release the lock. The motor is acting like a
generator and allows the lock to stay energized under the bowls inertia.
In a brown out situation, the machine will restart at the start of whatever section of the cycle it was
on and continue the wash. The lid lock would then be reactivated if it happened to be on a spin
cycle.
2.10 Inner and Outer Baskets
The outer basket is the assembly to which all the motor, pump system, suspension rods, etc are
mounted. Within the outer basket are the inner basket and the agitator. During spin, the agitator
and inner basket have to be coupled together and turn as a single unit. In agitate, the agitator and
inner basket are free to rotate independently.
The inner basket is free to move in a vertical direction. The position of the inner basket is
determined by the water level. At the base of the inner basket is a flotation chamber consisting of
a number of individual cells. When the machine is filling with water, the pressure on the air in
these cells increases as the water level rises until eventually the inner basket floats upwards and
disengages the driven spline from the drive spline. This action frees the agitator from the inner
basket and allows it to move freely in both directions.
517792A
18
When the water is draining, the pressure on the air trapped in the cells of the flotation chamber
decreases allowing the inner basket to settle back down onto the drive spline and re-engage the
driven spline, thus allowing the agitator and inner basket to turn as one unit. The floating basket is
also used to detect if the user has selected the correct water level for the size of the clothes load.
The point at which the basket starts to float is determined by the water level and the size of the
load. The greater the load, the more water is needed before the inner basket will float. By
detecting the point at which the basket floats, the machine can determine whether the correct
water level for the particular clothes load has been chosen by the operator. If the operator has
chosen a level that is too low for the load, the machine will override that choice and fill to the
correct level. This is to ensure optimum wash performance and minimal clothes wear. If the user
has selected a level that is higher than necessary, the machine will still fill to the users selected
level.
2.10.1 Detection Of Inner Basket Float Off Point – Basket Check
During fill the inner basket will rotate to ensure that the clothes are evenly saturated with water.
When the chosen water level is reached, and before the agitate cycle is started, the machine will
carry out inner basket float checks (basket check). The inner basket will stop and commence a
number of small agitate type actions. During this action the machine determines if the inner basket
has floated. If it has the machine will determine the required water level and check if the operator
has selected the correct level. If the inner basket has not floated, the machine will continue filling
and check again later. The water level at which the inner basket floats is not necessarily the same
as the final water level.
2.10.2 Detection of Inner Basket Re-Engagement – Basket Check
After the water has drained, the inner basket will sink down and re-engage onto the drive spline.
To ensure the inner basket has re-engaged correctly, the machine will carry out a basket reengage test sequence (basket check). Basket check consists of a series of short agitate type
actions before the spin cycle starts. A sound may be heard as the inner basket re-engages.
2.10.3 Balance Rings
The inner basket has 2 balance rings, one at the top, and one at the bottom. These are sealed
compartments half full of water. This water allows the basket to balance. If one or both of these
rings have lost water then the inner basket must be replaced. The easiest way to determine a loss
of water is to weigh the baskets on n accurate set of scales.
