I have a Whirlpool super capacity plus. It went along with the super capicity plus top load washer. We've had it about 12 years. It's always worked great.
My washer went out (5 kids and lots of use) so I bought a front load washer (Whirlpool Duet), which holds a lot more. Even though I didn't get the dryer that matches the front loader the 12 yr old whirlpool dryer is working fine.
Now I can wash my king sized quilts at home with the new washer. My drier works on the quilts...but I have to untangle them and flip them around to get the wet center spots to the outside, since the dryer isn't as big as the front load dryer that goes with the new washer. Since the dryer works I didn't see a reason to replace it unless we decide to rearrange and have a stacked washer/dryer set.
My dryer has an "automatic" setting which is supposed to detect when the clothes are dry enough. It's the setting I almost always use. It will also continue to tumble periodically for another 30 minutes or so (if you have that setting turned on) to keep the clothes from getting wrinkled if you don't pull them out right away.
Oh -- about mold on front loaders. I've had my front load Duet washer for a year now. Never any problem with mold. The manual says to leave the door cracked open when it's not in use...so I do that.
** Make sure if you have young kids that you use the "CONTROL LOCK" feature so it can't be turned on by little kids. I heard of a couple of kids being killed in them. One was a 3-4 year old, climbed in and the 18-24 month old pushed the door shut and started pressing buttons and it turned on.
