I have an LG washer and dryer that I love!! I puchased it a few years ago. No issues. It functions wonderfully and looks good. I loved my LG pair so much that I purchased an LG TV, LG free standing air conditioner, and a LG dishwasher. They all function great!

I have front load LG. I believe it's the 3900. No water hammer issues.

My LG front load washer was bought in 2005. The easily installed and inexpensive water hammer arrestors I installed did solve the water hammer issue.

That was 18 years ago. I was trying to create a thread with currant , within in3-4 years purchases. Everyone knows that there were issues.

Trying to see if the problem still exists, or if it has been corrected.

About 15 years ago, I babysat at my son's rental house and then in the house they purchased, and neither had a water hammer issue. The rental was a new build and the purchased house was built in the 1960's

I bought the WM4200 Fall 2021 and not any water hammer issue at all.
