Water Hammer is a serious problem

Because LG did not properly engineer the water shutoff valve, it closes too quickly, creating a problem called water hammer. Water hammer is created by rapidly shutting down a water flow. This creates a major spike in water pressurein the supply pipes. Left untreated, it will result in leaks in the pipes affected. google on WM3470 water hammer and you will get over 400 hits. Reviews for devices which treat water hammer frequently mention this model specifically. There is even an online video of this model with the water arrestor installed. A good water arrestor costs about $50. You will need two. LG service does nothing to help with this issue. We have a Bosch dishwasher which does not create water hammer. Our previous Amana washer also never produced water hammer. The source of the problem is the LG design, not your plumbing system. So buyer beware. LG has known about this problem for a long time, since early 2012. But they did not change their design. Like the GM ignition problem, which cost a few cents to correct, they instead decided that profit, not proper performance, was paramount. In the case of GM, lives were lost. In the case of LG, water pipes are being destroyed because many people do not realize the problem they are creating by running the washer without a water hammer arrestor installed. I am thinking of starting a class action lawsuit to force them to make a retroactive repair or to pay for the parts and installation of the hammer arrestor. To deal with the water hammer, you will need to purchase this part (or one of similar design and quality): Watts LF150A, Water Hammer Arrestor, Lead Free and this coupling: Watts LF150HA, 3/4 Lead Free Thread for 1/2 Water Hammer Arrestor. These work much better than the el cheapo ones at Home Depot which we tried only to return since they did nothing to arrest the water hammer problem.<br /><br />All of that said, the washer is quiet once the water hammer arrestor is in place. It does an excellent job of cleaning clothes. If you take care to dry the rubber ring which seals the door, you will have no issues with mold or mildew. Hence, two stars instead of one.
