Hot water in the ice cube box will make the ice on the
freezer floor melt and afford direct contact with the
metal freezer floor.  This will make the water freeze
faster than if the ice cube box and the freezer floor were
separated by a layer of ice (which is a good thermal
insulator), as will be the case if you were to start off
with cold water.
