Thanks
Thanks Appnut, Powerfin64, and Nmassman44 for your replies.
Nmassman44, I live in a house that was built in year 1926, which we bought in year 1976. Aside from (1) installing new vinyl tile flooring (in year 2000 or so) and (2) installing new shutoff valves (also in Feb when we got the new machine, because the old valves leaked and thy don't make those valves anymore) nothing (structurally) has been done to the laundry room since we bought the house. So given the fact the machine is on a pedestal, on a wood floor that is 47 years old (at least, I have no idea how old it really is), topped with vinyl tiles (which I read somewhere that LG specifically does not recommend), the machine is doing OK!
