1. A method of controlling a washing operation of a washing machine having a tub containing water, a drum rotatably installed in the tub, and a heater installed in the tub to heat water supplied to the tub, and a water supply pipe to guide water supplied from a water pipe through a water supply valve into the tub, comprising: supplying water into the tub through the water supply pipe;soaking a laundry with the water by rotating the drum;after completing the soaking the laundry, re-supplying water in the tub through the water supply pipe for controlling a water level in the tub to be a preset level required for a generation of steam; andgenerating the steam by heating the water in the tub using the heater, and supplying the steam into the drum through apertures of the drum,wherein the supplying the water includes supplying the water in the vicinity of a storage part provided at a bottom of the tub to allow the water to be supplied to the storage part without passing the laundry, andwherein the preset level in the re-supplying is a level that allows the heater to be submerged in the water, while not allowing a bottom of the drum to be submerged in the water. 2. The method according to claim 1, wherein the supplying the water includes forming in the tub a level that allows the laundry on the bottom of the drum to be soaked when the drum is rotated. 3. The method according to claim 1, wherein the soaking the laundry further comprises circulating the water in the tub. 4. The method according to claim 1, wherein the soaking the laundry further comprises heating the water in the tub. 5. The method according to claim 1, wherein the supplying the steam includes supplying the steam until an inner temperature of the tub reaches a preset temperature. 6. The method according to claim 1, wherein the supplying the steam includes supplying the steam until a preset time period is expired. 7. The method according to claim 1, wherein the supplying the steam includes supplying the steam until the water level in the tub is lowered to a preset minimum level. 8. The method according to claim 7, wherein the supplying the steam further comprises further supplying the water to the tub until the preset level is reached, if the water level in the tub is less than the preset minimum level. 9. The method according to claim 1, further comprising rinsing and spin-drying the laundry after the supplying the steam is completed. 10. The method according to claim 1, further comprising discharging water in the tub through a water drain pipe for generating the steam, after the soaking the laundry and before the re-supplying the water. 11. A method of controlling a washing operation of a washing machine having a tub containing water, a drum rotatably installed in the tub, a heater installed in the tub to heat water supplied to the tub, and a water supply pipe to guide water supplied from a water pipe through a water supply valve into the tub, comprising: supplying water into the tub through the water supply pipe;soaking a laundry with the water by rotating the drum;after completing the soaking the laundry, discharging water in the tub through a water drainage pipe for controlling a water level in the tub to be a preset level required for a generation of steam; andgenerating the steam by heating the water in the tub using the heater and supplying the steam into the drum through apertures of the drum,wherein the supplying the water includes supplying the water in the vicinity of a storage part provided at a bottom of the tub to allow the water to be supplied to the storage part without passing the laundry, andwherein the preset level in the re-supplying is a level that allows the heater to be submerged in the water, while not allowing a bottom of the drum to be submerged in the water. 12. The method according to claim 11, further comprising re-supplying water in the tub through the water supply pipe for controlling a water level in the tub to be the preset level required for a generation of steam, after the discharging the water. 13. The method according to claim 11, wherein the soaking the laundry further comprises circulating the water in the tub. 14. The method according to claim 11, wherein the supplying the steam includes supplying the steam until an inner temperature of the tub reaches a preset temperature. 15. The method according to claim 11, wherein the supplying the steam includes supplying the steam until a preset time period is expired. 16. The method according to claim 11, wherein the supplying the steam includes supplying the steam until the water level in the tub is lowered to a preset minimum level.
