Trickle to no water from dispenser / very little ice

Shutoff water and turn off fridge. Remove the main water hose from the fridge with pliers, then remove back bottom plate of fridge where the hose was at (about 5 screws) in order to disconnect the hoses going into the valve by pushing in on the plastic colored fastener(blue & white) while pulling on the hose at the same time. Do this for each of the hoses. Then disconnect the wires from the valve and unscrew the valve(1 screw) from the back plate. Replace with new valve which comes with brand new fasteners for the hoses so all you have to do is insert the hoses in the valve and reverse the above process to install the valve.
