Product review (5 stars): OEM Replacement Part Works Perfectly!
My LG WM2455HG front loader was giving an "FE" Error Code whenever I would run a wash cycle of more than 20-30 minutes (aka Speed Wash).  I researched the Error Code, and determined it could either be the Inlet Valves or the Water Level Sensor or the Sensor's Air Hose (If that hose is clogged with anything or torn open, it could artificially cause the same "FE" Error Code).  After further research it seemed to me that my machine was having an issue with the inlet valves due to high water pressure.  My water level sensor's air hose was clean and free of debris, and it wasn't torn or cracked anywhere.  So I decided to focus on the Inlet Valves.  I ran a long wash cycle with just the cold water, and determined that the "FE" code would still interrupt the wash cycle.  So this led me to believe it was the Cold Water Inlet Valve.

My original Hot Water Inlet Valve wasn't defective, but I decided to replace it at the same time as the Cold Water Inlet Valve was defective.  I noticed the parts were exactly the same with exception to the filter screen located inside the threaded opening.  The original part had a mesh steel screen with a rather large mesh opening compared to the new part that came with a plastic filter screen with much smaller holes in it.  My water lines have relatively high water pressure (100-105psi) and I don't have a Water Pressure Reducing Valve on my main water line, so I believe this is what led to the premature demise of the Cold Water Inlet Valve.  The smaller filter screen holes on the new inlet valves should also help reduce the incoming water pressure to a safer limit if you have high water pressure.  Hopefully this small design change will increase the lifespan of the water inlet valves!
