Couple things to add that haven't already been said:
1. If you have a bad smell in a front-loader, check under the seal. I found a kitchen sponge stuck in there and it reeked.
2. We have stopped using fabric softener and I that's been helpful for avoiding build-up on the drum. Fabric softener is basically wax. Actually makes your towels LESS absorbent, even if fluffier. We now use 1/2 cup cheap white vinegar. Everything comes out soft and no build-up.
