The musty mildew smell is because you probably have a mildew build up from not taking care of your machine properly. After every load, you're supposed to wipe it dry and leave the door open. This is common sense and is true of any front load machine. There are also products out now that you can run once a month that were made to specifically clean out front load machines. As for your clothes not getting clean, the more you full your machine is, the better they will clean. Instead of having a big agitater in the way, your clothes agitate against eachother, thus cleaning them and giving you more space to stuff more clothes in. I've own this machine for a year now and have never had any problems because I followed the owners manual. The only complaint I have is that it has a tendancy not to spin out all of the water when I wash heavier items (ie.. comforters, heavy blankets, all jeans). I think it is a fantastic machine for the price. We paid just under $600 for it.
