A:Answer Hello there! Thank you for sharing your experience with us. We understand your concern regarding water hammer issues, especially after having them with your 2016 LG washer. The WM4000HBA model has been designed with updated technology to minimize such issues, but depending on your home’s water pressure and plumbing setup, it’s possible that water hammering could still occur. We recommend installing a water hammer arrestor in your plumbing system, which can help absorb the shock caused by water flow changes, thereby reducing or eliminating the noise.
For further assistance or troubleshooting steps, feel free to send us a private message on social media @LGUSSupport. We’d be happy to assist you further.
