If the laundry box it self doesn't have water hammer arrestors this is definitely worth considering. They will hammer several times during a single load.If it's a newer washer, or maybe specific to LG, the way it shuts off the water so quickly usually results in a lot of pipe banging/water hammer. Could be the cause as to why your hoses failed. Putting some water hammer arrestors on usually helps, or turning the valve off slightly so it's not wide open.
People did try to sue LG over this as they claimed it damaged their pipes, but not sure it went anywhere.
They can be added after. @gingerbee
