2-2. NEURO FUZZY WASHING TIME OPTIMIZATION
To get the best washing performance, optimal time is determined by the water temperature,
the selected washing temperature, and the size of the load.
2-3. WATER LEVEL CONTROL
● This model incorporates a pressure sensor which can sense the water level in the tub.
● The water supply is stopped when the water level reaches the preset level, the washing
● The water supply is stopped when the water level reaches the preset level, the washing
program then proceeds.
● Spinning does not proceed until the water in the tub drains to a certain level.
