The water valve (#800 on the
#2 break down diagram) is located behind the back cover on the right side.
This part is not too difficult to replace yourself - just a screw and a couple nuts. Do not forget to turn off the water to the fridge first.
I would recommend one of most reliable in-line water filter which can help to eliminate odor and scale and improve taste of water. It comes with the braided stainless steel over nylon reinforced vinyl hose and brass fittings and is pretty simple to install.
