When an operation for washing is completed and door is unlocked, water level in a water tank is monitored only for a prescribed time period. When there is no water leakage, monitoring is stopped after the prescribed time period and the power is turned off. When there is a water leakage, water level in the water tank increases. When it is detected that a first water level is reached, the door is locked to prevent opening. After a prescribed time period, the power is turned off while the door is kept locked. If the door cannot be locked, the door lock error is notified and the water collected in the water tank is drained.

Washing machine capable of detecting leakage at water feed unit

A washing machine includes: a drum () in which laundry is put; an ion elution unit that elutes metal ions and adds them to water; a sensing unit () for sensing imbalance at the time of rotation of the laundry tub; and an imbalance correcting unit (). 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.
