PROBLEM TO BE SOLVED: To provide a washing machine whose water level detection accuracy has been improved at low cost.SOLUTION: In a water level detection correction step, water is supplied until water overflows from an overflow port 13 and the water level becomes substantially constant, and, based on a frequency detected by water level detection means 10 when the water level becomes substantially constant, accuracy variation of the water level detection means 10 is calculated from a difference with the frequency of the reference water level. Based on the accuracy variation, the frequency of each water level in a plurality of steps is corrected from each reference frequency and inputted in storage means as correction water level data, and in a water supply step, the water level is determined by the correction water level data.SELECTED DRAWING: Figure 1 |
