The washing machine has been a problem since day one. When water goes in and out of the washing machine, you get a water hammering noise that shakes the hose and  the pipes so loudly, I can hear it 2  floors up. LG says it is not their responsibility and I should buy a water hammering arrestor. I paid for these as well as for a plumber and it did not help at all. The Switch on the LG washing machine is obviously defective as it creates too much pressure as it opens and shuts. It’s very unfortunate that LG will do nothing about this and now I fear my pipes are going to be damaged and eventually burst.
