ABSTRACT:
A washing machine water level detecting method using a weight sensor for supplying water up to the decided water supply level and performing a next cycle if the determined water supply level is below the predetermined level, or measuring a displacement in accordance with water supply per unit and storing the measured displacement data in a microcomputer if the determined water supply level is above the predetermined level. The method enables an accurate detection of the water level in a washing machine without requiring an additional sensor.
