An ice machine has an ice-making assembly that includes a water distributor in which one or more structural elements form a first chamber. The first chamber is configured to receive an inflow of water, distribute the water laterally, and to controllably release the water. A mating member cooperates with the one or more structural elements to form a second chamber. The second chamber is configured to receive water from the first chamber and to controllably release the water onto a receiving surface. The mating member is configured to be detached from the one or more structural elements in a direction perpendicular to the direction of lateral water distribution.
