“Have the inlet valves been redesigned in this new model (WM3900HBA) to slow the closing of the valves? The previous models have well-known water hammer issues causing plumbing pipes to bang and thump everytime the valves close.”

Sorry, there was a problem. Please try again later.This is actually a problem with the plumbing in your home. When the water valve in the washer shuts off, it can cause pipes in your home to move, resulting in a loud banging noise. This effect, called water hammer, can be reduced by installing an item called a water hammer arrestor. Add-on arrestors can be purchased through your local hardware or home improvement store.
