I'm a mom trying to fix my ice machine. I have tested the water line to the fridge and it's clear. Emptied and cleared water lines from valve to filter back to valve and to machine. Put a new filter in. Nothing blocking. When I turned it one the lines never refilled. Does that mean I need a new valve or could it still be the actual machine? Is there a way to test if it's the machine or the valve. There had been a clicking noise for months and when the ice stopped the clicking stopped. Thank u in advance
