This water hammer is caused by the actuation of the solenoid valves in
a clothes washer. It rattles the pipes, particularly the vertical ones
behind the bathroom wall.
Where is the best place to position an arrester? I had suggested
that one be temporaily attached to the nearest faucet (faucet then
left open, of course) to see if there was any effect before permanent
in-line attachment.
Which brings me to my next question: Do they always work?
Thanks in advance.

re Do they always work?

That one's easy: No.

re: attached to the nearest faucet

That might help...certainly worth a try. Although if it doesn't, it
must just not be the right location, so you might not really know.

re: rattles the pipes...behind the bathroom wall.

Any chance these pipes are accessible? Sometimes just securing the
pipes better will stop the banging.

Are any nearby pipes accessible? How about the hoses to the washers?
There are so many different types of arrestors, including homemade air
chambers, that it all depends on how accessible any given connection
point is.

DAGS for some ideas.

The ideal location is as close as you can get to the valve causing the hammer,
with the air trap portion of the hammer in line with the direction of the water
flow from the source pipe. Since that's not always possible, you try to get as
close to the valve as reasonable.

Lowes sell screw on hammer arrestors that attach to the valve the washer (or
dishwasher) hose screw into. I was very pleased with their performance on a
dishwasher install. Saves having to open up the wall.

It seems to me that the old soldered in style of stub pipes are no longer
allowed by code, but I don't know why. Maybe because they saturate over time and
you have to drain the whole house.

Thank you both. I will follow Rick's advice and try the
screw-on hammer arrestor that Lowes sells. At the same time,
we'll try to better secure the pipes that run up behind the tub.

Please repost without capital letters (and with punctuation if
possible.)

Come to think of it, I don't know what this means, so changing to lower
case won't help.

Like all "Green" consumer goods designed by the federal government under the influence of the tree and cloud huggers, none of them do the job very well and always seem to cost more money to obtain and repair. o_O

It's the price for saving the planet.
Things just, simply, don't work.

Another poster has already mentioned the water hammer arresters made for laundry room faucets. But there are many types. Here's a good link to a plumbing supply company with some very educational information on the subject. 8-)

That does matter to me sometimes (like when it's time to get dressed and
Im' still doing the laundry!)

Sometimes I stand at the machine with the lid open and advance the timer
when I think it's been doing the same thing long enough.

I stayed in a rented house with a front loading machine and there was no
way to advance the timer by hand. I hope if I ever have to buy a new
machine I remember all the things I want it to have. (I once bought a
car with no cup holders. It didn't occur to me to check if it had any.
It took me 2 years to make my own, but it was beautiful when I was
done.)

Perhaps a whole new industry could form around hacking and modding controls for those despised "Green" appliances. I remember when it was a big thing to buy a performance chip for a Chevy engine control computer so the car would run better and get better gas milage. 8-)

I walked in the office and quit, told them where to send my money.

For the record, I'm allergic to work.
