A spray arm assembly for delivering a fluid under pressure into a dishwasher wash chamber consists of a spray arm having a rotational axis and defining a fluid passageway for distributing incoming fluid into the wash chamber, a tower section, structure for mounting the tower section to the spray arm for guided movement relative to the spray arm between a retracted position and an extended position, and structure on the tower section for directing fluid from the fluid supply into the wash chamber with the lower section in its extended position. Mounting structure, integrally formed with the spray arm, prevents the tower section from separating from the spray arm with the tower section in its extended position. Any number of cooperating tower sections can be employed.
