Abstract: A dishwasher includes a cabinet having a tub, a pump and at least one spray arm. The at least one spray arm has a flow path guide and first and second flow channels separated from each other. The flow path guide has a first opening to allow wash water to flow to the first flow channel and a second opening to allow wash water to flow to the second flow channel. A valve is coupled to the flow path guide and is configured to open or close one of the first opening and the second opening. The valve includes a rotatable float. The rotatable float closes the first opening while opening the second opening at a first point in time, and the rotatable float rotates to open the second opening while closing the second opening at a second point in time.
