SMART DRIVETECHNOLOGY
The Smart Drivewasher technology is different to
anything you may have seen before.
A brief description follows.
MOTOR CONTROLLER MODULE
This module contains the circuits needed to control
the water valves, pump, water level and rotation of
the motor.
The Pressure Sensor, used to detect the water
level, is part of the Motor Controller Module and
cannot be removed.
DISPLAY MODULE
This receives the inputs from the front panel (i.e.
User settings) and sends the appropriate command
to the Motor Controller Module.
NOTE: Electrostatic Discharge Sensitive
procedures should be observed for all electronic
component handling.
There are no field serviceable parts within the
Motor Controller or Display Module.
MOTOR
The motor is a 3-phase DC brushless motor. The
Motor Controller Module controls rotation of the
motor. Fitted to the Stator (stationary part) is the
Rotor Position Sensor. This detects the position of
the Rotor (moving part) and feeds a signal back to
the Motor Controller Module.
Between the Yellow and Blue connector the
resistance will be 32 ohms. The same resistance
should be measured between the Blue and Red
connector, and also the Yellow and Red connector.
WATER VALVES
The electronics control the water valves so that a
constant wash water temperature is achieved
irrespective of the temperatures and pressures of
the incoming hot and cold water. Two different
valves are used. It is important that the correct
water valve is fitted should they need replacement.
The cold water valve can be identified by the white
(or blue) filter and the hot valve by the yellow (or
red) filter.
IMPORTANTES CONSIGNES DE SÉCURITÉ

- 2 -
FLOATING BASKET
During spin, the agitator and the basket have to be
coupled together and turn as a single unit. In
agitate, the agitator and basket have to be free to
rotate independently.
At the base of the basket is a flotation chamber. As
the water level rises the basket will float. This
action disconnects a clutch between the agitator
and basket. The agitator and basket can now
move independently.
When the water is pumped out, the basket sinks
down and re-engages, allowing the agitator and
basket to turn as one unit.
DRAIN PUMP
The drain pump motor is attached to the base of
the tub. The pump housing is an integral part of
the tub. The pump can be accessed from the top, if
the agitator and basket are removed, or from
underneath the machine.
DIVERTER VALVE
A diverter valve is located underneath the tub. This
directs the tub water to the drain hose or to the re-
circulation hose. The valve is on whilst the
machine is filling and re-circulating the wash water.
It is also turned on briefly at the beginning of the
rinse cycle to allow the re-circulation hose to
empty.
LIDLOCK
This machine has a lidlock that will lock the lid
closed when the machine is spinning. If the lid is
open at the beginning of rinse or spin, the machine
will stop and sound a warning tune. See user
warnings
OUT OF BALANCE SWITCH
A lever and switch is located in the right rear corner
of the topdeck. If the switch is activated the
machine will stop and sound a warning. (See User
Faults).
LINT REMOVAL SYSTEM
As a result of the agitator action, lint and wash
water is drawn into the agitator stem and down to
the base, where they are directed into the cavity
between the basket and tub. The holes in the
basket allow the wash water to flow back into the
basket but prevent the lint from following. Lint is
carried out with the waste water.
OPTION ADJUSTMENT MODE
The washer can be adjusted to operate under a
number of different conditions. The feature is
called OPTION ADJUSTMENT MODE. Features
that can be controlled include:
•Rinse Options
•Number of End of Cycle warning beeps
•Automatic Out of Balance recovery
•Automatic water level adjustment
•Softener rinse volume adjustment.
•(See Use & Care Manual for details)
USER FAULTS
Incorrect installation or operation can cause user
faults. The washer can detect these and alert the
operator by a musical series of beeps and either
displaying a warning on the screen or flashing an
LED. These are also listed in the Use & Care
Manual.

DETAILED FAULT DESCRIPTIONS
GWL11
To obtain the detailed fault description, firstly enter
diagnostic mode (as described above). Then press
SPIN SPEED UP or DOWN buttons until the HOLD
and SLOW spin LED’s are on. The detailed fault
code can now be read from the wash progress
LEDs. See diagram below. For each LED that is on
add the values together. The LEDs with the value
‘32’, ‘16’ and ‘1’ are on, therefore
32 + 16 + 1 = 49
Fault Code #49 is displayed
IWL12
The Fault Status screen will display a code for the
last fault that has occurred in the machine. It will
also display how many cycles ago that the fault
occurred, and at what part of the cycle. Some
common fault descriptions are shown in the
following columns, for full detailed fault code
information refer to the Service Manual. See
Detailed Fault Codes for servicing tips.
Machine Size Error
Fault code #9
The machine size setting does not match that
stored in the memory. See MACHINE SIZE
SETTING above for corrective action.
Pump Blocked Error
Fault code #37
Machine has not drained out. Check that the pump
is not blocked or that the drain hose outlet is not
crushed or blocked or drain hose outlet is too high.
(Maximum is 7 ft.)
Pressure Tube Fault
Fault code #39
The probable cause of this fault is that the pressure
tube has become blocked, crushed or has fallen
off.
Basket Disengage Fault
Fault codes
#40
#47
The floating basket has not engaged even though
the pressure sensor indicates that the tub is empty.
Check that the clutch or the pressure tube is not
blocked or crushed.
Out of Balance Switch Fault
Fault code #43
The out of balance switch is permanently activated
or the harness to it is disconnected.
Hot and/or Cold Water Valve Faulty
Fault codes
#48
#49
#50
Check that the valve harnesses have been
connected correctly or valve is not open circuit.
Diverter Valve Fault
Fault codes
# 51
#52
Wash water is not circulating correctly in the re-
circulation hose. Check that diverter valve is
directing the water flow to the correct hose i.e.
during filling the water should be directed to the re-
circulation hose. There should be no flow in the
drain hose. Failure in the diverter valve could be
due to blockage in the valve, a wiring fault or fault
in the motor controller module. Check that there
are no leaks in any of the hoses. Also check
resistance of diverter valve.
Rotor Position Sensor Error
Fault codes
#130
#131
A faulty signal has been received from the Rotor
Position Sensor. Check for bad connection on the
harness between the Rotor Position Sensor and
the Motor Controller, or a faulty Rotor Position
Sensor.
High Motor Current
Fault codes
#132
#133
The Motor Controller Module has detected excess
current in the motor. Check the motor harness,
connectors and motor for shorts. Check the Rotor
Position Sensor and harness for water, mechanical
damage or corrosion. If all the above show no
signs of fault then replace the Motor Controller
Module.
Motor Stall
Fault codes #136
The Motor Controller Module has been unable to
start the motor. Possible causes of this fault are
faulty motor harness, faulty or jammed motor,
seized bearings or seals, faulty Motor Controller
Module, faulty Rotor Position Sensor or harness.

9. If the valve is replaced, ensure that a hose
clip is refitted to secure the hose to the tub.
Specifications are subject to change without notice.
After Reassembly and Testing…
If the machine is advanced to either rinse or spin
whilst filling or re-circulating, it may take up to 3
minutes before the drain pump turns on. This time
allows the diverter valve to cool down and direct
the water flow to the drain hose.
