I have an older Whirlpool front-load washer that's stinky. I periodically clean it inside and out (including the folds in the seal) but the smell keeps coming back. Last time this happened, I took the machine apart and found mold in the drain hose; replacing it fixed the problem. But now two months later, it's back again.
Is there any way to fix this problem permanently, or should I break down and replace it? If so, is there anything I can replace it with that won't simply exhibit this problem again?
