We've been using this machine for a couple months now, and here's my experience so far:
The Good
It does a good job cleaning. It does so effectively and quietly. I like the app features (but more on that later) that let you control the unit to a degree from your phone. Since we have ours in the basement, I also like that I can check the estimated time remaining in the cycle remotely and that it sends me a push notification when my washing/drying is done. The lint trap is far easier to clean than my previous dryer. I like that the front control panel does not have any "printed-on" button labels - on my old machine, the lettering rubbed away, likely from age/exposure to solvents in the cleaning products. That should not be an issue with this design. I also like the central placement of the control panel vs. stacking units that could go side by side, which would make the dryer controls positioned above my head. Overall the performance has been good so far, but I am a nit-picky person, so...
The Bad
While the lint trap is easy to clean, I also have to clean the rubber door gasket on the dryer every couple of cycles, as it collects lint on it in a way my old machine never did. I thought the rear vent inside the dryer was starting to rust, but upon further inspection it looks like it may have had some kind of adhesive on it that has collected lint which is now stuck to it. I have found some of the settings to be counterintuitive, or require some backtracking to get the machine to do what I want. For example, some settings (let's say a particular water temperature, steam, etc.) are only available in certain wash modes. I find I end up going through a cycle setup only to find that I can't do steam and then need to start again, guessing at a different mode that hopefully will allow me to input the settings I want. I could also look through the manual each time, or eventually memorize them all (?) but that's not any more convenient to me than what I'm doing now. I wish I had more control rather than the unit deciding it's smarter than I am. If I want to super steam my delicates, I should have that right. Similar story with trying to activate the interior light - sometimes it will let you, sometimes not. Why must use of the light be restricted at times? Who is the light going to hurt? Though I really like the app, it's crazy that so much basic functionality is locked away in there instead being accessible from the main control panel of the unit. For example, it is not possible to set a delayed cycle from the main control panel, but this can be done through the app. I cannot fathom how this point got through a product design review. This is incredibly basic functionality, and there are so many opportunities for it to break - if I don't have a smart phone or if its battery dies or I don't have it available, if I don't have wifi or the wifi in my house goes down, if the wifi hardware fails on the washer/dryer, if the wifi signal is bad from my router to the washer/dryer location, if LG decides to stop supporting the app or to start offering it as a subscription service. If any of these things happen, then basic functionality of the unit is entirely inaccessible. And that's just what I can think of right now. Who was in charge of this decision? It's NUTS! The app is great, but some of these functions should really be part of the physical control panel.
