Consumer Reports tested it very recently, and it received a total score of 79, putting it in the top one-third of the tested machines. The dishwasher at the top of the ratings (a Bosch) received an 82. In other words, it tested very well for CR.
HOWEVER: LG is rated the lowest in reliability. Whirlpool is listed as the most reliable brand.
I have a two-and-a-half year old LG and it has performed flawlessly. It cleans well and is very quiet.
