My old model ( 12+ years) LG washing machine died. So, a new one was installed in mid-October 2022.   The new machine made many unusual sounds which my older model did not make.  In December an LG technician came out and said that  these  unusual noises were related to a new, and  smaller more efficient drain pump, LG should have put that information in the owners manual and saved me a lot of hassles.  Other than that, the clothes washer works just fine. The LG technician also had some great tips,  which I appreciated. very much.
