I've read that the front loaders have issues of mold/mildew growing in the gasket for the door. Anyone else hear about or experience this?

After 4 years our Kenmore Elite front loading washer stopped draining, it was because a built in trap was clogged with the crap little kids keep in their pockets, like rubber bands and coins, in addition to lint, etc. I googled the problem and fixed it myself. While googling the problem I read that people were smelling mildew for similar reasons, the trap clogs a little after years of use and water doesn't drain. It looks like the trap needs to be cleaned every couple of years. Unfortunately the trap wasn't designed to be reached easily. It's not a hard job, but requires a few tools to get the job done.

I still like the washer and dryer pair. The dryer keeps up with the washer, for one thing. A front loading washer is also easier on clothes, and our clothes seem to be staying in better shape for a longer period of time.
