Abstract
Abstract A clothes washing machine has a controller which can be set for a winter operation mode, i.e., when the wash water is relatively cold. In the winter operation mode, the weight of laundry articles in the wash tub is determined. If the weight is less a reference weight, the laundry articles are washed for a first time period. If the weight is more than the reference weight, the laundry articles are washed for a longer time period.
