Yep it turned out the second valve is faulty. I made sure the voltage supply is good to confirm there is no issue with the control board as well.

Thx for your help

I also had this problem and ended up replacing both valves as water would not stop flowing into the ice maker tray. i relaced that valve a second time and now have no ice. When i pour water into the tray everything works fine; just wont supply water to the tray. I already checked the fill res/cup and it is empty and not frozen. What else do I need to check before replacing the ice maker as a whole ?
