I'm at a dead end here with this washer. It started out throwing LF code at first wash of day and now it has progressed to every wash now.I have replaced just about everything inside of this washer. replaced both water valves twice,replaced flow sensor, even replaced the ecu and front face board. after all that it still does the same code. I have reset the codes everytime and have checked the hoses and water pressure from outlet in utility room. the washer and dryer was purchased in 2014 and are in excellent shape.I could use some help with this situation to fix the problem. thanks in advance
