Abstract: A washing machine includes: a drum (630) in which laundry is put; an ion elution unit that elutes metal ions and adds them to water; a sensing unit (701) for sensing imbalance at the time of rotation of the laundry tub; and an imbalance correcting unit (702). When the sensing unit senses imbalance in the drum at the time of spin-drying rotation of the drum performed after metal ion added water supplied from the ion elution unit to the drum is supplied, the imbalance correcting unit corrects the imbalance by performing a processing different from a processing performed when imbalance is sensed in a case where the metal ion added water is not supplied. The different processing is not supply of tap water but balance correction rinsing in which the metal ion added water is supplied to the drum and agitation is performed.
