A washing machine includes a rotary drum, a water tub, a water supplier for supplying water into the water tub, a water level detector for detecting water level of washing water in the water tub, and a circulating pump capable of rotating at a variable rotational speed. The washing machine further includes a water circulation system for circulating the washing water in the water tub into the rotary drum with the circulating pump, and a controller for controlling the rotational speed of the circulating pump. In a rinsing process, the controller also drives to rotate the circulating pump at a first rotational speed (S3) before the water level detector detects the water level (S4), and drives to rotate the circulating pump at a second rotational speed faster than the first rotational speed (S7) after the water supplier starts water supply (S5) and after the water level detector detects that the water level of the washing water is not lower than predetermined water level (S6). |
