I have an LG front load that is about 13 years old. Just started getting the IE error. Replaced the flood safe hoses with new open style supply hoses. That didn’t fix it. I then replaced the hot and cold water inlet valves. This didn’t fix it either. I did the self diagnostic steps and all steps run except for the main wash step. No water flows and the solenoid for that hose isn’t getting 110v. I also replaced the water level pressure switch. This main wash solenoid has a white wire and two black. I pulled the main pub board and check continuity on the white wire back to the solenoid and it was good ... had continuity. Not sure what’s left. The other two solenoids in the same cold water valve have 110v and work fine. Busted wire ? Bad main board? Any help is appreciated
