A laundry is fed into a washer and a valve transfer knob(3) is set to the function of washing and rinsing and a mechanical rotary timer(2) is turned to set to the desired washing time. In case the water is supplied in excess of the normal, a pressure switch(12) is on and a discharge pump(13) is driven, according to the choice of a water flow switch(4), strong or weak, a gear clutch(10) changes either washing or rinsing. A valve transfer knob(3) is adjusted to drainage and a drainage valve(8) is opened, and the pressure switch is on, having the drainage pump(13) operated, thus the gear clutch changes to the drainage(10) and the discharge is carried out.
