Product review (5 stars): Works great, no drying problems for us
We've had this for a few weeks and it is working really well.

I was terrified by the other reviews here, because I knew that our only option was to drain into a wall drain. I even asked my plumber to mount the drain low, but because of code he wouldn't do it.

It hasn't been an issue. Three things other customers taught me to do that have helped:

1) Fill the drum halfway. We've experimented and gone a little more than halfway, and been okay.
2) Drain the little drain house at the bottom of the machine (in front). There's a little door in front of the machine that opens, and there's a small hose and twist off trap. Make sure you tighten the twist off trap, because it will leak if you don't (trust me, I saw firsthand!).
3) Don't panic when the laundry is done and feels a little damp. It dries almost instantly.

I'm not sure if the complaints about the dryer were a design defect that LG has since fixed, but I would guess that some folks didn't follow the above steps.

It does take a little longer to dry, and you can't just stockpile tons of laundry and expect to have everything done. But not having to use a 220 electrical socket and vent out the window is a huge plus, as is running a continuous wash and dry cycle.

I'll update the review if something changes, but it looks like the dryer part of this works fine, and we certainly aren't using a bucket or floor drain.
