An automatic washing machine in which an initial filling time required for filling a tub with water to a predetermined level at the start of a washing process is measured and stored in a memory, whereby time required for rinsing process is automatically determined on the basis of the measured initial filling time. Means is provided for determining the rinsing time duration on the basis of a preset rinsing time stored in the memory in place of the measured filling time when the latter is abnormally short, thereby to assure an adequate rinsing action.
