Water Temperature Sensing

WashSmart, GW, WA & FabricSmart, IW Machines
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 the Use & Care manual.
Specifications
NTC-type temperature sensor (Thermistor)
Resistance 10KΩ @ 25

As there is no thermistor (temperature sensor) in this Washer the only temperature that can be
adjusted is the warm wash temperature. The temperature of the warm wash is entirely dependent
on a number of factors:
a. Cold water temperature
b. Cold water pressure
c. Hot water temperature
d. Hot water pressure.
e. Warm wash setting.
As the above will vary from installation to installation it would be impossible to predict what
temperature each installation will ultimately achieve.
However under the conditions outlined below, a temperature of between 36–38
achieved.
Cold water temperature: 20
Cold water pressure: 320 kPa (46.5 psi)
Hot water temperature: 60
Hot water pressure: 320 kPa (46.5 psi)
Warm wash setting: Default setting (9 min wash LED – 3rd Green wash LED from the left).
3.4.1 Warm Wash Temperature Adjustment (QuickSmart MW Only)
The warm wash temperature adjustment will alter the amount of time that the hot valve pulses on
and off for.
1. Turn the machine on at the wall but of at the console.
2. Press and hold down the START/PAUSE button, then press the 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 Warm Wash Temperature.
4. Advancing the Wash Progress LED by pressing the ADVANCE button will increase the wash
temperature. If the ADVANCE button is continually pressed, the light will scroll back to the
coldest setting available for that wash temperature.
5. Press the POWER to 'lock' in the setting.
