For obvious reasons, the water hoses tend to thump against the wall and the sheet-metal back of the clothes washer, so I added foam disks to mute the noise:

They’re closed-cell polyethylene foam, laser-cut from a sheet about 15 mm thick. The cut is a yawning 2 mm wide near the top, but it pretty much doesn’t matter in this application.
The black line in the split is a snippet of the usual outdoor-rated foam tape, which probably won’t stick well to PE foam. If these fall apart, a cable tie around their waist should suffice.
The nice clip in the foreground is one of two intended to corral the drain hose. It’d be nice if LG included a few clips for the water hoses, but no matter where they were, the hoses would want to go elsewhere.
