PURPOSE: A method for sensing water level of a washer is provided to prevent damage by velocity change of a washing motor and to prevent an accident by sensing frequency of the water level sensing device. CONSTITUTION: A method for sensing water level in a washer comprises a first stage(S1) pressing an operating key by input laundry into a washing tub; a second stage(S2) memorizing present water level frequency into a first memory; a third stage(S3) deciding optimal water level corresponding to the laundry; a forth stage(S4) supplying water into a specific water level; a fifth stage(S5) renewing a second memory by water level frequency value of water pressure sensor; a sixth stage(S6) deciding whether the water level frequency of the second memory is the same as the optimal water level; a seventh stage(S7) washing while the water level frequency of the second memory is the same as the optimal water level; an eighth stage(S8) deciding whether water supplying time is over specific time by discordance of the frequency; and a ninth stage(S9) deciding whether the present water level frequency is empty water level frequency. |
