Product review (4 stars): Worth the Purchase for large Family
It's quiet, it is big and it handles as much as you want to put in, and it is expensive. If you wash large items, big loads, this machine does it.
Did a lot of research and read what few reviews were out there - some myth, some true, and decided to purchase this. LG's reputation continues to strengthen, and thats a good thing - 1 star for that; purchased Washer & Dryer for $1900 delivered with all hookup accessories - 1 star; given a two year warranty - 1 star; and it cleans as advertises - 1 star; hope it lasts.
Like any new toy, I ran a small load and watched it, and immediately understood why some people complained about clothes not coming clean - read the manual folks. There are two myths that need to be dispelled: First, you do not need a lot of water - this uses very little water, barely enough, but it works excellent; Second, you do not need an agitator that beats the crap out of clothes to clean them - watching how this cleans and it became evident that the way it works is very efficient even with large loads. What is important is how you put in a load, read the manual. For large items, make sure you don't spread it out. Because this is such a large drum, one must pay some attention to how the large items go in - clothing is not as particular, as small items move a lot. However, if a single item sits in the very middle of the drum and does not reach across the drum, it will not come clean because it gets the least amount of agitation - once again, read the manual.
Concerning Noise - it is quiet, very quiet, with the exception of the rinse cycle. A cascading waterfall is used with the water spreading over a larger area as the tub rotates so that the clothing is rinsed evenly (and thats the noise). It does this a couple of times and does a thorough job of rinsing. The spin cycles are quiet, and do an excellent job of removing the water - you can even select really high spin. Note: high spins put in wrinkles that need to be steamed or ironed out.
Load size - in one load washed queen sized comforter, a blanket, two throw feather comforters, and a set of sheets. Flawless, and everything clean. Big star...and there was still room for more. A second load had 3 sets of sheets lots of pillow cases, and a queen comforter thown in - not a problem. But do not recommend these kinds of mixed loads - they won't dry...even in the largest dryer LG has (i got that too). Blankets, sheets, will wrap up in a ball, especially in the large dryers, consequentially, the stuff that got swallowed up just doesnt dry well. I ended up having to finish with an air dry for some items or seperating out and cycling again. Absolutely no problems with large loads of clothing, and I might add that my jeans did not come out in knots. If you are going to dry large loads of sheets/blankets, take a peek every ten minutes and see if they need pulling apart (love the glass window).
If you install under cabinets, make sure there is clearance when the lid is open, if installed on a pedestal, get a step stool or you will never get to the bottom of the tub.
Final words on washer: Worth the purchase for large families, or if washing large comforters, sleeping bags, this is it. Still a little pricey so shop around.

Dryer: It dries, and does it well. Dried as large of a load of clothing that the washer could produce. Other than the issues of loading multiple blankets/sheets that ball up, I have no real complaints with the drying or steam functions. The lint trap design could be better. It uses a clam shell catch that has to be opened for cleaning - somewhat of a nuissance, but it does the job. To maximize efficient drying, a straight exaust tube will really make a difference. Worth the Purchase.

BTW, when done washing/drying, be prepared for a plesantly surprising musical concerto.

Will add to this review as I learn More.

Update:  experienced loud rattles in the washing machine but ony during the wash cycle.  Could not duplicate with the next load, but happened again on the third load.  Apparently, metal snap-buttons on shirts can make a lot of noise in the big drums.
