2-2.FUZZY LOGIC 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

program then proceeds.

Spinning does not proceed until the water in the tub drains to a certain level.
