My Kenmore Elite H3t started having a smell of mildew for the past year. I would put bleach through it 3 times in a row with no laundry and it would seem to be better for 2 loads. I thought I was leaving the clothes in too long sometimes (1-3 hours after complete).
Well in looking for the common problem of why my washer wont work, I found that many, many people have the same issue.
Do you have a front loader washer that stinks? Check this out.

By the way, I have my washer tore apart in my laundry room, thinking about dropping the bin.
