I have LG Direct Drive Front load washing mashine, everything sounds and work fine except this annoying hissing sound when the drum (metal barrel) rotate during different wash cycles its not a loud sound, to hear it you should isolate every sound in the surroundings its like an electrical or magnet hiss sound i don’t know how to describe it, it sounds like sssssssssss please help because it’s irritating on long periods washing cycles thank you all

That is usually the water inlet valve leaking. Do you ever have a little water in the tub after it has been sitting for a while? Is there a specific action the machine is doing when you hear it?
