spin dry tub 24 is forwardly rotated at the same speed and in the same direction when the pulsator 28 is forwardly rotated and repeats the idling fuzzy course when the pulsator 28 is backwardly rotated such that a fourth water current stronger than the water current in the third washing mode but weaker than the water current in the second washing mode can be formed unlike the third washing mode the fourth water current generates circulation or movement of cloths in the spin dry tub 24 to increase washing efficiency by which damage to the clothes is decreased such that the fourth water current is adequate to protection of cloths and washing of dirtier cloths turning to fig1 the washing control method thus operated according to the present invention includes steps s 510 s 520 s 530 s 540 for selecting one of a plurality of cloth or one of a plurality of washing courses and steps s 511 s 521 s 531 s 541 for controlling a water current according to the selected cloth or selected washing course the water current control method thus established is stored in a microcomputer and is embodied by a course selected by a user the method comprising a first water current control method wherein the pulsator and not the spin dry tub rotates in forward backward direction a second water current control method wherein a spin dry tub repeats forward backward rotations in opposite directions to those of the pulsator a third water current control method wherein the pulsator and the spin dry tub rotates in forward direction only and a fourth water current control method wherein the second water current control is alternatively operated under the third water current control state by.
