Thanks, John, for the tips. When we first bought the original version of this washer in 2000, I would say we were probably doing washes of 70% warm-water, 20% cold and 10% hot. We've always used liquid chlorine bleach, but only on our white washes, which were perhaps one load every other week.
In the past few years, we've switched to doing maybe 60% warm washes, and 40% hot. (I think I've got hubby trained now to not do any more cold washes, LOL.)
We started leaving the detergent drawer open when I noticed mold growing on it the first time, and I didn't want to have to clean it again. We didn't leave the washer door open, because it would swing open wide on its own and I didn't want our cats crawling inside. We never noticed any odor problem, though, and I regularly checked.
The new washer door seems to rub on its hinge against its hole in the case, thus it will stay put if I only open it slightly.
I like that feature I've seen on some of the new front-loaders where there is a clip to hold the door open slightly. Also, I think the ones that have a built-in fan to dry everything out inside is a good idea.
