The steamer will continue to run even if there is no water left in the tank. You will notice it begin to make a clicking sound and no steam will be emitted. Please pay attention and turn your steamer off (and refill the water tank) right away when this occurs. The steamer will only turn itself off in the unlikely event that it begins to overheat.
