Water Supply
 For best operating conditions your hot water should be approximately 149˚F. The hot water
should not exceed 167˚F or the cold water exceed 95˚F. Temperatures above these may
cause the machine to fault or cause damage to the machine.
 If there is an uncontrolled water-heating source (eg a wet back or solar heating) a tempering
device should be fitted. This will ensure the hot water temperature remains within safe limits.
For the most suitable type of tempering device we recommend a local plumber or plumbing
supply merchant be contacted.
 Inlet Water Static Pressure 3psi (20kPa) to 150psi (1MPa).
Note: If using a header tank, then the top of the header tank must be at least 2 metres above
the top of the clothes washer.

2 THE UNIQUE AQUASMART™ WASH
The AquaSmartis a SmartDrivebased washing machine that has two modes of washing, High
Efficiency & Conventional. It is essentially a front loader and a top loader washer in one.
Both washing modes start the same way, with a detergent activating wash.
Detergent Activating Wash
AquaSmart™ fills at the selected water temperature, with just enough water
so that the clothes are saturated. This concentrated detergent solution is
then recirculated through the wash. This thoroughly dissolves and
activates the detergent.
High Efficiency Mode (front loader type wash)
In the High Efficiency mode, the AquaSmart™ then fills with just enough
cool water to lift the clothes off the low profile agitator, so that when it
rotates, the clothes gently roll over each other. This wash uses similar
quantities of water to most Front Loaders and so, not only are there the
benefits of water savings, but also the higher detergent concentrations give
optimum soil removal.
Conventional Mode (top loader type wash)
The Conventional mode is the immersion wash all Top Loader users are
familiar with. After the Detergent Activating Wash, the AquaSmart™ fills
with cold water until the clothes are underwater, whilst gently turning the
clothes over. We recommend this mode when the dilution effect of water
can solve or prevent common wash problems. For example when dye or
colour run can be a problem, or when washing sandy towels. Sheets are
better washed in this mode. Some cycles can be used in both modes,
whilst others work in only one

3 ELECTRONICS
3.1 Motor Control Module
The Motor Control Module used on the
AquaSmartwasher is similar to the other
Phase 7 washers in its physical size and shape,
however the electronics have different software
to control the unique aspects of this machine.
Therefore the Motor Control Module is specific
to this machine and is not interchangeable with
any other Phase 7 machines.
The text on the yellow identifier label (P7SPL)
stands for Phase 7, SmartPump™, Low profile
Agitator.
3.2 Control Panel
The three core components of the control panel are the console, the IMD facia, and the PCB and
housing. A new look that differs from existing machines has been created, so now capacitive
touch buttons drive a high-resolution dot matrix display. The facia provides a sleek look and no
protruding buttons makes it easier to clean.
Console – Part number 420957
The console, which is made from ABS, is the
housing to which the facia and PCB housing
attaches. Lugs at the base of the console
locate into the top deck. The console is secured
to the rear of the top deck by two screws.
IMD Facia – Part number 421075
IMD stands for In Mould Decorative display.
Clear plastic is moulded over the decorative
polycarbonate silver film. The last process is to
mould the seal on to the facia. The IMD
process means a reduction of parts and any
subsequent printing process.
•No lens.
•No light pipes.
•No separate buttons.
•No separate seal.

517794B

PCB and Housing – Part number 421052
The PCB, which contains the capacitive touch
buttons and LCD, is mounted within a plastic
housing. The PCB housing is clipped into the
console at the bottom, and secured with four
screws along the top.

5 WATER VALVES / DISPENSING SYSTEM
5.1 Water Valves
The water valve assembly incorporates four
valves that are joined by a common valve
body. The two main inlet coils control the flow
of water into the valve body assembly that then
in turn supplies water into the machine through
the inlet nozzle.
Two additional coils are used that control the
valves for the fabric and detergent dispensing.
They control the flow of water to the detergent
and fabric dispensing system via hoses that
run underneath the top deck.
1. Hot coil (White Clip)
2. Cold coil (White Clip)
3. Fabric coil (Yellow Clip)
4. Detergent coil (Purple Clip)

5.2 Dispensing System
Two hoses of different lengths run underneath
the top deck and connect to either the
detergent dispenser or the fabric softener. The
detergent dispenser hose has cream elbows.
The fabric softener hose has grey elbows.
Moulded into the top deck at the valve end are
identification letters (‘D’ for Detergent and ‘S’
for Softener). At the dispenser end are
moulded the words ‘Detergent’ and ‘Softener’.
It is important that the hoses are retained in the
clips around the perimeter of the opening of
the top deck correctly.
5.2.1 Detergent Dispensing
During fill, the detergent valve is also energised. This allows a proportion of the inlet water to flow
into the detergent dispenser.
The flow rate through the detergent valve is dependent on the inlet water pressure, but it is less
than the flow rate of water entering the machine. The valve will remain energised until the water
level reaches 1 inch (25mm), at which point the bowl starts stirring until the desired water level has
been achieved.
The detergent valve can be tested in diagnostics (refer to Section 14).
5.2.2 Fabric Softener Dispensing
The design of the fabric softener is such that it creates a self-siphoning effect. When the motor
control module calls for fabric softener, the fabric softener valve will energise. This allows water to
flow into and through the dispenser mechanism. The initial burst of water starts the siphoning
process. The valve is pulsed on and off for a total of 95 seconds (see table below) to ensure that
all of the fabric softener has dispensed.
On Off

10 10
10 10
10 10
10 10
Note: The 1st off time of 15 seconds is to ‘kick start’ the siphoning process.
If the fabric softener valve was to run continuously, the water would cut a path through the softener
and the bulk of the softener would remain in the dispenser. The maximum level of the softener is
90mls to the ‘Max’ mark. If the softener dispenser was to be filled higher than this mark, the
softener may self-siphon into the machine.
The softener valve can be tested in diagnostics (refer to Section 14).
5.2.3 Inlet Nozzle
In addition to its design, which ensures excellent rinse water distribution, the nozzle shares an
important relationship with the inlet valve assembly and the dispensing system as described
above.

517794B
15
An internal piston within the nozzle moves with the amount of water pressure against it. When the
water pressure is high, more holes in the nozzle are exposed, and the backpressure on the
dispensing valves is less.
When the pressure is low, more backpressure is created, which ensures that either during
detergent dispensing or fabric softener dispensing the dispensing system takes priority.
If the water pressure was very low during dispensing, it is conceivable that no water would enter
the machine via the inlet nozzle until the dispensing has been completed.
Conversely, if the piston was jammed, and the water pressure was high, a high flow rate of water
would go through the dispensing system and may result in water on the floor.
6 LOW PROFILE AGITATOR
The unique low profile agitator works well in both the High Efficiency and Conventional modes. In
the High Efficiency mode, the clothes have greater contact with the agitator due to the low water
level, and the agitator ensures a high level of clothes turnover.
In the Conventional mode, the clothes are completely submerged in the water and the curving
steep side walls and raised shoulders of the wash plate vanes create enough inward and upward
movement to keep the cloths turning over even when there is reduced contact with the agitator.
Top View Underside View
7 WATER LEVEL MEASUREMENT
The AquaSmartuses the same pressure sensing system used in the SmartDriveand Intuitive
Eco™ machines to determine the water level. The difference with AquaSmartis that on both the
Conventional or High Efficiency modes, AquaSmartwill automatically choose the water level, as
the precise water level for the clothes load is critical to the performance of the wash. The amount
of water used in either mode is unable to be selected or adjusted by the user.
So now there are an infinite number of water levels that AquaSmartcan choose depending on
the weight and type of the clothes being washed, as opposed to the more traditional 3 or 5 water
levels on previous machines.

8 SMART PUMP™
SmartPump™ provides a more flexible and efficient pumping system than a conventional
pump/diverter valve combination. SmartPump™ can be diverted quickly, it reacts faster and is
better controlled. In addition, SmartPump™ has the capability of pumping to a much higher head
whilst maintaining a constant volume flow rate regardless of pump efficiency degradations due to
age.
8.1 SmartPump™ in Detail
8.1.1 Hood and Cap
The hood and cap form the top of the pump
housing, which must seal to the outer bowl.
The hood and cap filters out objects that
cannot pass through the pump system.
8.1.2 Flapper Valve
A diverter valve has been integrated into the
pump cavity and operates automatically with a
change in pump direction. This change of
direction moves a flapper valve, which diverts
the water to the drain hose or to the re-
circulation hose. The valve is sealed off
against the port face with water pressure.
8.1.3 Impeller (non-field serviceable)
The impellor imparts rotational energy into the
water and keeps sand away from the shaft
seal.

8.1.4 Rotor and Stator
The rotor and stator magnetically interact with each other in order to convert electrical energy into
rotational movement of the rotor
Rotor
The rotor assembly is a complete unit that is
permanently fixed into the pump housing. The
resulting cavity is charged with water, which
acts as a lubricant. In the event of a failure of
the rotor, the whole assembly must be
replaced.
Note: Contained within the rotor cavity are
seals and bearings that are non field
serviceable. The bearings provide a low
friction wear surface for the rotor shaft to run
on, and the seals eliminate grit from the rotor
and bearing cavity
Stator & Shield
The Stator is mounted to the base of the pump
housing together with the shield & cap. The
harness connector inserts into the underside of
the motor. Care must be taken to isolate the
machine from the mains power before
servicing the pump, and it is important that the
harness connector cover has been refitted
after reassembly.
8.1.5 Pump Housing
The pump housing is bolted directly to the
outer bowl. It contains the volute shape and
flapper sealing faces and also provides a
structure to attach stator and rotor assemblies.

8.3 SLR Feature
SLR Feature stands for Simplified Leak
Recirculation. This feature has been added so
that should the flapper not completely seal
against the housing of the pump when draining,
water can bypass through this hole and back
into the pump, avoiding recirculating back into
the bowl and on to the clothes load.
It is important that this hole remains clear, and it
should be checked whenever the pump is
serviced.
8.4 Testing the Stator
SmartPump™ Wiring Diagram
The stator resistance can either be tested from the harness to the motor controller or at the
connections to the stator itself.
8.4.1 Testing SmartPump™ Stator From The Console
The resistance of each individual winding is
approximately 8.1Ω+/- 10%, however when
testing the stator from the console we are
testing across two windings, therefore the
resistance should be approximately 16.2Ω+/-
10%.
To test all windings you will need to measure
across:
• Red and White
• Blue and White
• Blue and Red

If the meter shows an incorrect reading, we would recommend testing the stator from underneath
the machine, as there could be a fault in the wiring harness. To test the stator it will need to be
removed from the machine (refer to Section 17.12).
8.4.2 Testing SmartPump™ At The Stator
After removing the stator it can be tested.
To test across all windings you will need to
measure across the centre and the two outer
terminals.
Note: Do not measure using the two inner
terminals as these are not used.
If an incorrect reading is obtained, remove the
stator shield and inspect the stator. Ensure that
the three spade terminals are fitted correctly
and have not been dislodged.
If the fault cannot be remedied, the entire pump
assembly must be replaced.
