1. A method of controlling a laundry apparatus, the method comprising:
supplying, in a water supply step, wash water into a tub of the laundry apparatus through a water supply valve;
circulating, in a fabric soaking step that occurs after termination of the water supply step, the wash water by operating a circulation pump and driving a drum of the laundry apparatus;
heating, in a heating step that occurs after termination of the fabric soaking step, the drum by driving an induction heating module of the laundry apparatus; and
washing, in a main washing step that occurs after termination of the heating step, by driving the drum,
wherein the induction heating module is located on the tub and configured to heat the drum through induction heating,
wherein the circulation pump is configured to pump wash water into the tub and supply the pumped wash water to the drum,
wherein the fabric soaking step is terminated based on a water level of the wash water being a circulation water level, and the water level of the wash water is maintained after circulating the wash water, the circulation water level being lower than a lowest end of the drum,
wherein the heating step is performed while maintaining the circulation water level, and comprises heating the drum, the wash water, and laundry by driving the drum, the circulation pump, and the induction heating module, and
wherein, in the heating step, a driving period of the drum and a driving period of the circulation pump are identical to each other or a portion of the driving period of the drum overlaps with the driving period of the circulation pump.
