What does the SensorWash feature do on my GE Profile Washer?

The SensorWash senses the incoming water temperature and adjusts the fill water to obtain a more precise temperature range for all three wash temperatures (cold, warm, or hot). For example, some warm water may be added to a Cold Wash selection to reach the temperature needed to better dissolve detergents. The SensorWash will not adjust the fill on warm wash unless the washer lid is closed. (Page 6)
