LG front loader main wash slow filling

Good morning this is my first post on this forum. I have an LG front loader model WM0642H. It is now seven years old. I have recently noticed that the main wash portion of the fill is doing so very slowly. The prewash fills normally, followed by the main wash which fills slowly. The hose valves are working normally, the inlet filters have both been cleaned. Considering that the prewash is filling normally I am puzzled. This occurs during the initial fill. I have not watched long enough to observe the fill nor the rinse cycles

Any suggestions would be greatly appreciated. If more information is needed, please let me know and I will do my best to oblige
