Warewash machine with removable rotating arm and related method

A warewash machine arm for ejecting liquid in a warewash machine, the arm comprising:

• an arm body formed to provide an elongated interior liquid flow space along an arm axis, the arm body including one or more liquid ejection orifices;
• a mount hub connected to the arm body, the mount hub including a mount opening and a releasable latch mechanism that includes a first slidable actuator mounted for linear sliding movement relative to the mount opening and a second slidable actuator mounted for linear sliding movement relative to the mount opening, each of the first slidable actuator and the second slidable actuator having an interior end portion biased toward an axis of the mount opening and an exterior end portion biased away from the axis of the mount opening, such that movement of the exterior end portion toward the axis of the mount opening slides the interior end portion away from the axis of the mount opening, enabling latch mechanism release via a squeezing operation of the exterior end portion of the first slidable actuator toward the exterior end portion of the second slidable actuator.
