Bought this newer model based on recent high marks from online reviewer for highest reliability for LG dishwashers. So far, have only used a few times. I must admit there's still a leaning curve at least for me due to all of the bells & whistles including Wi-Fi interface. Also big change from older models simpler start-up and lack of so many options. However, so far seems to do a very nice job of cleaning. Love the interior lights and third rack.
