Abstract
A fully automatic washing machine comprising a washing/dehydration basket, an agitator rotatably disposed inside the washing/dehydration basket, a motor for rotating the washing/dehydration basket or the agitator, a detector for detecting the amount of wash corresponding to the washing load, a detector for detecting the level of water in the washing/dehydration basket, and a control circuit for controlling operations of washing and dehydration processes. Water-reserved-starting of the dehydration process is effected in such a manner that dehydration is started while leaving a certain quantity of water in the washing/dehydration basket. The amount of cloth is detected by the cloth amount detector before the start of the washing process or at an initial stage of the same, and a value thus detected is stored in the control circuit. Washing water is discharged while reading a signal from the water level detector before the start of the dehydration process, thereby leaving a certain quantity of water corresponding to the cloth amount value previously stored.
