LG washing machine has AWFUL mildew smell

I bought my LG washer & dryer set in July of 2006 and have taken great care of these machines. Just 5 months ago the washer started smelling like mildew even though I dry inside the rubber seal on the door and leave the door open to air dry inside after I'm finished with the laundry. I've been in contact with LG & Home Depot where I bought them and they've advised me to run bleach through it, empty the drain located on the front, rund Whirl Out through it, etc...
I've done all of these things and still have this horrible smell coming from inside the drum itself. The water that I emptied from the drain had no odor. When I clean under and in between the rubber seal on the door there is no sign of mildew or the odor on the towel that I use. I stick my head inside the washer and it's obvious that's where it's coming from. I was told the tub has a 5 year warranty on it. I don't know what else to do. I've wasted so much time of course trying to do everything possible (without taking this stupid thing apart) to make this smell go away or find the actual cause and no such luck. In researching the internet I've found where I'm not the only person having this problem, knor is LG the only washer that has the mildew smell, but they're all front loaders with the same problem. I've reported it to consumer affairs, but I don't know what else I can do! I spent so much money on this machine and it makes me sick to think that I'm stuck with a mildew smelling washing machine!!! HELP>>>>>>>PLEASE!!!!!!!!!
I began noticing that my towels had a musty smell - like the "shower house at a campground in the mid-west - in July!" a couple months after purchasing it. I read in the manual to run a 'tub clean' cycle with bleach, so I did. The smell always came back, so I finally called a repair man. He checked some things out, and said I needed to buy "Afresh" tablets, and use one once a month, so I did. Three months later, my machine smells most of the time, and we can only use our towels after two or so showers. By the way, we live in dry Colorado. I finally decided I do not want smelly towels (or house) for the next 10 years, so I have spoken to the manager of the store we purchased it at, and he has (thankfully) agreed to exchange it :). Now, I don't know whether to risk trying another front loader or not!
I bought a LG TROMM and the same. Some clothes retain the smell and for a while I thought that some clothes were dry rotting or something. It also seems to be natural fibers retaining the stench. I used strong fragranced fabric softener, liquid and two or three sheets in the dryer. I rub the tub clean cycle about once a week and leave the door open. No luck.
