1. A controlling method of a washing machine including a steam supply unit to evaporate water and supply steam into a drum and a washing heater mounted to a tub to heat washing water in the tub, the controlling method comprising: supplying washing water with detergent into the tub, wherein the supplied washing water is lower than a predetermined water level;performing a high concentration washing process by rotating a drum;supplying steam into the drum to increase an inner temperature of the drum by operating a heating part of the steam supply unit and without directly heating the washing water;supplying washing water without detergent until the washing water reaches the predetermined water level after the high concentration washing process and the supplying steam;performing a dilution washing process by rotating the drum;operating the washing heater when the washing water reaches the predetermined water level to increase a temperature of the washing water without operating the heating part of the steam supply unit and directly heating the wash water; andrinsing the laundry after the dilution washing process; andspin-drying the laundry. 2. The controlling method of claim 1, wherein the supplying of washing water to perform the high concentration washing process includes supplying washing water through a detergent box into the tub until a water level of the tub reaches around a bottom surface of the drum or at which a heater in the tub submerges. 3. The controlling method of claim 1, wherein the supplying of steam includes supplying steam until a temperature inside the tub reaches a predetermined temperature. 4. The controlling method of claim 3, wherein the supplying of steam includes supplying steam after the high concentration washing process until the temperature reaches a predetermined temperature appropriate to sterilize the laundry. 5. The controlling method of claim 4, wherein the predetermined temperature is between 40° C. and 80° C. 6. The controlling method of claim 3, wherein the supplying of steam includes supplying steam during the high concentration washing process until the temperature reaches a predetermined temperature appropriate for enhancing an activation of detergent. 7. The controlling method of claim 4, wherein the predetermined temperature is between 40° C. and 60° C. 8. The controlling method of claim 1, wherein the supplying of steam includes supplying steam for a predetermined period of time. 9. The controlling method of claim 1, wherein the supplying of steam includes repeatedly supplying steam with time intervals. 10. The controlling method of claim 1, further comprises circulating the washing water in the tub by using a circulation pump and re-supplying washing water into the tub. 11. The controlling method of claim 1, wherein the supplying washing water into the tub to perform a dilution washing process is performed when the washing water of high detergent concentration remains. 12. The controlling method of claim 11, wherein the predetermined level is predetermined based on an amount of laundry. 13. The controlling method of claim 1, wherein the operating of the washing heater includes operating the washing heater until a temperature inside the tub reaches 40° C. or higher. 14. The controlling method of claim 1, further includes sensing a water level of the tub while a motor to rotate the drum is turned off. 15. The controlling method of claim 10, further includes sensing a water level of the tub while a motor to rotate the drum and the circulating pump are turned off. 16. The controlling method of claim 1, further comprising: wetting the laundry and circulating the washing water supplied into the tub to the drum, which are carried out simultaneously, while the high-concentration washing process is carried out. 17. The washing method according to claim 1, further comprising: wetting the laundry, circulating the washing water supplied into the tub to the drum, and supplying steam into the drum, all of which are carried out simultaneously, while the high-concentration washing process is carried out. 18. The washing method according to claim 1, wherein the steam supplying is controlled, thereby the interior temperature of the drum being maintained at an optimum temperature level.
