Senses the quantity and quality of wash load to determine the water level and wash cycle appropriate for the wash load. Before the start of the entire wash cycle, press this button so that as the various processes take place, the machine keeps saving them in memory as the Favourite Program. This customized water level selector allows you to add some \'Extra\' water at any selected water level. If the water flow stops during the water filling process, the machine starts hibernating. If the water level shows no rise in level in the next 15 minutes the machine indicates by flickering LEDs. Ensures that your program settings stay the way you had set them in case of a power failure. If there is an imbalance in the wash load, the machine automatically stops, tries to redistribute the load evenly and resumes washing.
