The invention discloses a washing control method and a washing machine. The washing control method comprises a washing step, a rinsing step and a dewatering step, wherein the washing steps is used for providing washing water to control a motor to operate at predetermined rotation time and stop time to wash and detecting the height of a water level in a bucket in real time to supplement water correspondingly; the rinsing step is used for discharging the washing water to control the motor to dewater at a dewatering period that the stop time is longer than the rotation time and providing rinsing water to rinse; the dewatering step is used for discharging the rinsing water to control the motor to operate to dewater at a rotation stop period that the stop time is longer than the rotation time. According to the method and the machine, the water is automatically supplemented during washing so as to prevent the influence of reduced water quantity on the washing effect; the rubbing time of clothes can be prolonged by controlling the motor to operate at the predetermined rotation time and stop time, so that the clothes have a better rollover effect; the motor is fully cooled through the dewatering period that the stop time is longer than the rotation time so as to reduce the temperature of the motor.
