         4 . The washing machine according to  claim 1 , further comprising:
 a water supply unit; and   a speed detector to detect a rotating speed of the drum,   wherein when the rotating speed of the drum reaches a predetermined speed, the controller controls the water supply unit to supply water to the door.   
     
     
         5 . The washing machine according to  claim 1 , further comprising:
 a circulation unit to circulate water in the drum,   wherein when a washing or rinsing operation has been completed, the controller controls the circulation unit to remove residual bubbles from the door.
