* Because the detecting ability of the sensor may be decreased by using it for a long time, periodically use

* Even if the water level or the water temperature are changed by the user in FUZZY(Normal) Program, 

the sensor will still work. The sensor algorithm may differ according to models.

and red in turn. And, after detecting, the LED lights a specific color according to the detecting condition as
follows:  

If the current washing condition (Detergent quantity, Water Temperature, water quality, etc.) is determined as
better than the standard one, it optimizes the algorithm to save the energy by decreasing washing time/strength,
and the LED automatically turns to red.  
If the current washing condition is determined as worse than the standard one, it optimizes the algorithm by
increasing washing time/strength, and the LED automatically turns to orange.
If the current washing condition is determined as equal to the standard one, the algorithm has no change and the
LED turns to green.
