Primary water valve

Hi. I do see you have 2 water valves on this unit. If you have one that is leaking or not closing all the way there is a way we can find out. We will have to isolate one of the valves or take a look at the water lines. There is no information on this unit to show me which valve is first in the system. The last valve in the system must be the one not closing or we would not have a leak. Even if the first valve was letting some water pass through the second valve would stop water flow. One valve is going to be your water inlet valve that the water line coming to the unit should hook up at. Then the water will flow through some water lines and to the other valve. Where is that water leaking at? Is it dripping at the water dispenser or over filling the ice maker? The SMART valve is located under the ice maker section in the parts break down and it only has one port coming out of it so I am thinking this may be the ice maker valve. But it could also be the valve that is first in the series for both dispenser and ice maker. You will need to figure out which valve the water runs through last to get to is destination where you have the water overflow at. You can do this by tracing the water lines through the system. I can not find any videos anywhere for this ice maker. We are currently working on having one for the future. However the document I attached in your previous question has a complete instruction sheet on how to get to the ice maker. Please refer to that for your ice maker repair.I have attached the parts break down for this unit as well.
