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.
2-4. DOOR CONTROL
The door can be opened by pulling the door handle whenever washer is not in operation. When the cycle is completed, the DOOR LOCKED light will turn off.
