An ice maker appliance, the ice maker appliance comprising:

• an ice engine comprising a water supply opening;
• a flow control device;
• a lower reservoir comprising a supply outlet opening;
• an upper reservoir comprising a body, the body comprising a side wall and a base wall, wherein a supply inlet opening, and an ice engine supply opening are formed through the body, and wherein the body forms a receiving plenum at which water is received from the supply inlet opening, and wherein the upper reservoir comprises an articulatable top panel permitting selective access to the receiving plenum, wherein the top panel couples to the body;
• a water supply conduit fluidly coupling the upper reservoir to the ice engine, wherein the water supply conduit fluidly couples from the ice engine supply opening to the water supply opening, wherein a water filter is positioned fluidly upstream of the water supply conduit and the ice engine;
• and
• an upper reservoir supply conduit fluidly coupling the lower reservoir to the upper reservoir, wherein the upper reservoir supply conduit fluidly couples from the supply outlet opening to the supply inlet opening, and wherein the flow control device is configured to selectively feed water through the upper reservoir supply conduit from the lower reservoir to the upper reservoir.
