Drain Pump Test

GW Washer
When in diagnostic mode to activate the drain-pump press the REGULAR button. To deactivate
the pump, press REGULAR button again.
5.3

Water Valve Test

The water valves can be activated in diagnostic mode by pushing WASH TEMPERATURE UP
button to activate the Hot Valve and WASH TEMPERATURE DOWN button to activate the Cold
valve.
Pressing each button once will activate the valve. To de-activate the valve press the same button
again. This is also good to use when installing machines as it takes the shock out of the fittings
and seals and allows checking for leaks on the inlet hoses, at both machine and tap ends.
Caution: Do not leave the machine unattended when either or both valves are operating.
5.4

Recirculation Valve Test

The recirculation valve can be activated while in diagnostic mode by pressing the DELICATE
button to turn the Recirculation valve on. Then fill the Basket with water to the low level indicator
on the agitator using the WATER VALVE TEST procedure (refer to 5.3). Once the water is at the
Low water level mark, activate the pump by pressing the REGULAR button; the water should
recirculate from the rear right hand corner of the inner basket. To turn the recirculation valve off
press the DELICATE button, the recirculation valve will take up to 3 minutes to cool and close,
allowing the water to drain. Once water has drained press the REGULAR button to stop the pump.
5.5

Restart Feature

If a fault occurs in the machine, the diagnostic system will detect it. However, instead of displaying
a fault code immediately, the machine will try to restart. If the fault was only of temporary nature,
the machine will restart and finish the cycle. If there is a continuous fault the machine will try to
restart a number of times.
This process could take up to 8 minutes depending on the type of fault. After this, if the machine
still cannot restart, the fault code is displayed and the machine will beep continuously. The number
of retries will depend on the fault that it has detected, however the maximum number or retries for
any one fault is 32 times.
The restart feature is turned on when a machine leaves the factory. For servicing we strongly
recommend that this feature be disabled.
To disable the restart feature follow the procedures below:
1. Enter diagnostic mode (Refer to Section 5).
2. Press WATER LEVEL DOWN button so that the low water level LED is not lit.
3. Press POWER button to turn the display off (the 5 leftmost wash progress LEDs will be
flashing).
4. Press POWER button to turn the machine on.
5. The machine can now be tested on any cycle.
