"Water hammer arrestors" will stop the noise in the pipes. If it's just the hoeses dancing and knocking around, I'd simply attach them to the washer - use some duct tape or similar.

check your water pressure. if it's over 100 lbs, adjust the regulator to about 90# and if you don't have a regulator, BUY ONE!

oh, and what the "trainee" suggested, but high water pressure can cause issues with appliances so start there and install the anti-hammer device if high pressure isn't the issue.

I didn't have the hoses dancing around but had the "clunk" noise. I also have arresters soldered on my pipes, and they weren't helping the washer.

Go down to your plumbing supply store and get ones that attach to the washing machine spigot. Actually I have the the water hammer arrestors and then the water leak hose detectors attached to mine. Stopped the problem.

Google "Sioux Chief 660-H 3/4in Female Swivel Hose Thread X 3/4in Male Hose Thread Mini Rest" to see what I am talking about.

Thanks, all. Sioux Chief looks like a simple enough solution. (Isn't it interesting that Amazon packages them with a pressure meter?)
