during rinse cycle. The water circulation system uses both water and detergent more efficiently.
RollerJets
Washing ball enhances wash performance and reduces
damage to clothing. The jets spray and help tumble clothes to enhance washing performance while maintaining fabric care.
Automatic Wash Load Detection
Automatically detects the load and optimizes the washing time.
Built-in Heater
Internal heater automatically heats the water to the optimum temperature on selected cycles.
Child Lock
The Child lock feature prevents children from pressing any buttons to change the settings during operation.
