2.0 INTRODUCTION

This Service Supplement contains information on the Product Specifications, Diagnostic Mode and
the Detailed Fault Codes. For all other Service and Option Adjustment information please refer to
your GWL03 Service Manuel part number 426348.
Note: The water temperature adjustment in the Option Adjustment mode is only available on
model GWL03. Model GWL10 has 5 preset temperatures which are factory set and are non­adjustable.

The detailed fault codes in this Service Supplement can also be used for GWL03 Smart Driveä
washing machines.

PERFORMANCE CHANGES

The introduction of model GWL10 sees changes to the way the Smart Drive wash cycle is
composed.

RECIRCULATING SMART DRIVE SYSTEM

The machine will start to fill with the temperature selected by the user. The bowl will only fill until
the clothes load is 100 per cent saturated with water. The machine will stop filling and begin the re­circulating phase (for every cycle except Permanent Press, which features a traditional full bowl
fill). The water in the bowl is pumped up through the re-circulating hose and back into the bowl
onto the clothes, with a fan-like spray pattern. As the water recirculates, the bowl will stir, pausing
every 16 seconds. Short top-ups may occur, as garments absorb water, keeping the water level
constant. Recirculating this small amount of water dissolves detergent, activates enzymes plus
bleach that will then penetrates dirt at fibre level, accelerating the wash process.

After 3 minutes, the bowl will begin to fill with cooler water (cold controlled to 16°C/61°F) to the
level selected by the user, or, if auto is selected, to the level chosen by the machine and will begin
to agitate. Because the wash cycle has already been boosted, less agitation time is needed.

The default rinse setting for the regular cycle of the GWL10 consists of a series of multiple shower
rinses and spins that flush water through the clothes, assisted by the specially designed nozzle.
Fabric Softener cannot be dispensed during this rinse. If fabric softener is required, the Softener
Rinse Option must be selected. This will convert the machine to a spray and deep rinse, which will
allow the fabric softener to be dispensed correctly.

The Smart Driveä washing machine has 2 load sensing methods to ensure the right wash action is
used for the type and size of wash load.

· LSD - Load Sensing Detection is used to continually sense the load and automatically adjust

the agitation profiles to suit the wash load. It is also used to determine when a maximum
capacity profile needs to be used. If additional garments are added during the cycle the washer
will adjust accordingly, increasing the amount of water and changing the wash profile. If the
machine is operating on high water level, regular cycle, with a very large heavy load, then the
Load Sensing Detection will activate the Maximum Capacity Profile.

· MCP - Maximum Capacity Profile is present in the regular cycle, high water level only. It is

clearly noticeable. The machine will stop agitating and restart with a perceivably different
profile. The agitation time will also increase by 1 minute. MCP usually occurs 1-3 minutes into
the wash and will, of cause, only occur if the machine is heavily loaded.

ELECTRONICS

The electronics for Series 10 Smart Drive are now air cooled instead of being water cooled as in
previous models. This has been made possible by changes to the stator winding which allows a
lower current through the electronics and the use of the latest low loss semiconductor-switching
device.
With the Series 10 Smart Drive you can no longer turn the machine on by using the cycle buttons,
you must press the Power button first.
The delay start is now 1, 3 or 9 hours; previous models were 1, 6 or 9 hours. This change was
introduced as a result of the last customer survey.
On the Delicate and Permanent Press cycles the medium spin speed can now be selected if required,
the default setting is still the slow spin. This was done to improve the customer's options, as slow
spin left the clothes too damp for some customers.

Electronic Modules are not inter-changeable between models. The different modules for the
different models can be identified by their color. Phase 3 modules are green, Series 8 modules are
yellow and the latest Series 10 modules are Grey.
It is important not to mix the different colored modules as they are not compatible with each other
and you will find that the washing machine will not work. It will automatically display a fault code
and beep if the modules have been mismatched.

STAND BY MODE

If the washing machine has not received any instructions for 15 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. 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 on and off or the
machine turned off and on at the power point.

WATER TEMPERATURE SENSING

The Thermistor for sensing the water temperature is now located in the inlet chamber ( GW models
only ) and will be available as a separate spare part under part number 479164P. See specifications
for the temperature/resistance reading.

WATER VALVES

The water valves are now 24 volts and are not interchangeable with previous model Smart Drive
washing machines. The terminals have been changed to the "RAST 2.5" system. Extra care must
be taken to ensure these connections are plugged in squarely to avoid damage to the terminals.
When removing the harness plug from the valve you must release the small retaining clip located on
the solenoid coil behind the plug.

RECIRCULATING VALVE

The Recirculating valve is situated at the bottom of the bowl, and is connected to the pump. If the
valve should leak or block then to service the valve, (working under the machine) remove the hose
clips connecting the hoses to the valve, and remove the screwed clamp around the inlet hose to the
valve. The valve now can remove for cleaning or checking.

The valve can be tested in the DIAGOSTIC mode by pushing the Delicate button. This will turn
t

he valve on and off.

Note: T

he valve will take approx. 1 minute to activate and approx. 3 minutes to cool down and

return to it default position.
