lg lmxs30776d Fridge water issue

[Motomax]

Hello, I have a lg lmxs30776d fridge that won’t dispense any water from the door but will make ice no problem. 
so far I’ve tested the two valves in the door that control the water to the dispense and the ice maker. Everything is working correctly, The water dispenser triggers the door valve solenoid. 
The main water valve on the back of the fridge only activates with the ice maker. It does not activate with the water dispenser so no water flows through the main water line that feeds the door. 
The Water dispenser worked randomly once while I was trouble shooting everything. 
I’m at a loss here. I’m thinking maybe the main controller board?

Did you ever find out the problem?

Just had one. I messed with the door switches and it started to work.
