The water hammer arrester installed at the washer is not large enough to suppress the water hammer you are experiencing. This could be due to the length of the pipe between the washer and the water heater or the number of turns in the pipe. Water hammer can occur at right angle turns. Install another arrester near the water heater or at a turn where you hear the hammer sound occur.

What causes the hot water hose to vibrate while filling the washer?

Tru adjusting water pressure. Does the fill valve or hose have a pressure regulator? Try without this. Often the sound is generated from the watertap.

Pulsation water lines

What you are experiencing is known as "water hammer" It is caused when flowing water under pressure is turned off rapidly. The pipes then shake from the shock of the shutoff. Properly routed and secured water lines are less prone to this anomaly. You can install water hammer arrestors on the washer supply lines. They can be purchased at almost any hardware store or home center. Water hammers can cause pipe joints to fail and should be avoided if possible. The one below connects directly to the washer supply fitting. You then connect the washer hose to it. You'd need one for the hot and another for the cold line.

What type of hammer arrestor do I buy to fix banging pipes after installing a new Moen posi-temp cartridge?

Banging pipes are a result of improper piping support. If the piping is secured, the banging will stop. If your only option is to install chambers for water hammer, any will do. Their only purpose is to hold air.

Just recently, when the water valve that fills the washer closes, there is a loud bang. Otherwise, the washer works just fine. Is this a concern?

This is called water hammer. It is from AIR in the pipes - and the valve on the washer slamming shut.

There are devices that install into your pipes called hammer arrestors.

Check with a plumber to have them installed properly.

Water pipes making noise trying to locate

Good luck! If it is "water hammer" and you already have water hammer arrestors (dead end sections of pipe) the the arrestors MUST be water logged - when you drained the system how long did you leave it open after empty? Sometimes it can take a little while for the arrestors to drain after reaching "empty". The proper solution is to get the arrestors working or add more - not trying to find the noise and dampening or muffling it (the arrestors do more than stop banging!)
