A control method for layered washing in a dishwasher and a dishwasher itself, which includes: S: determining a rack that holds items to be washed; S: determining a first spray water path corresponding to the rack that holds the items to be washed; S: controlling a water divider piece to rotate to a position that opens the first spray water path, thereby connecting the first spray water path to a water supply device and closing other spray water paths; S: performing a pre-washing step, so that the spray water path sprays towards the rack holding the items to be washed. The method first determines the rack holding the items to be washed, and then determines the first spray water path of the rack, so that the first spray water path is connected to the sink, and other spray water paths are blocked from the sink.
