Our LG Side by side. Our LG Side by side fridge freezer model number GR-P207QE has stopped

Question

Our LG Side by side fridge freezer model number GR-P207QE has stopped producing ice, we can still get cold water but thats all. I have checked the water inlet fed from the mains through the filter up to the bottom connection of the fridge. water supply is connected to a blue valve with 2 solonoids one for the water dispencer and the other for the ice maker. There is water up to this valve but no water getting to the ice maker. At this point I am stuck as to how do I confirm which part is required. Help! Kevin
