"I got the LG dishwasher about a year and a half ago. It's the quietest dishwasher I've ever heard--you can hold a conversation right next to it while it's running without raising your voice. It gets full marks on that point.
Unfortunately, a dishwasher's primary function is not to stay quiet, but to get the dishes clean. In this regard, the LG is sadly lacking.
Frequently, the items in the top rack (especially glasses) do not come clean. This happens once or twice every month. Once the dishes have dried, there is nothing the dishwasher can do to clean them--they have to be scrubbed by hand.
I've been able to reduce the frequency of the problem by leaving extra space between the dishes in the top, and not putting anything in the top center. But this reduces the effective capacity of the machine significantly, and sometimes the problem occurs despite these efforts.
All in all, I am unimpressed."
