I wish the solenoids for water flow were a little more dampened, they're very abrupt and cause some "water hammer" effect.  Also, it was bit a of bear to get delivered/installed--by LG's delivery people!  They pretended not to know how to unstack the unit and it took a cash bribe to get them to do the considerable work to get it installed in my condo.  Final issue is the app/notifications are sometimes kinda stupid.  Every 30-40 cycles it asks me if my hoses are hooked up properly, for example.  

Otherwise, it does a great job!
