Installing a water hammer arrestor at the washer water supply will help. It is also a sign that the supply lines in the wall were never secured properly. The only way to fix those is opening the wall so I would try the hammer arrestor first. Here is one so you know what you need:https://www.amazon.ca/Sharkbite-Washing ... 762&sr=8-3
