Robert,
Use your common sense
Anybody knows that ,if you turn off a refrigerator or freezer and not leave the door ajar,you'll get mildew and mold. Front AND top loading washers do the same thing. Top loaders have build up on the outer tub interior. Take apart any Whirlpool line washer and you'll see it foemed.on the plastic liner of the outer tub. The front loaders line, LG or Electrodaire,GE or Samsung,all have the magnet.to leave the door ajar without it swinging out too far. The Whirlpool products have a door that isn't as free moving as.the rest and may be left open a bit without swinging all the way out and in the way. If.one.follows the simple directions of wiping the boot and leaving the door ajar,no mildew will ever begin growing because the humidity and moisture are evaporated. My front loaders of all brands, Frigidaire GE, Maytag, LG, Asko, Westinghouse,Miele, Bosch, and Philco of Italy , never.,never,ever got any kind of growth in them. I always left the doors open and wiped the rubber boot to keep everything fresh and ready to use again.
In my sales profession, I taught my customers who bought the front loaders and or the combination front load LGs,how to do their wash on these and how to maintain them. Those who followed through were never heard from again. Those who didn't were always calling to pitch a bitch about,mold or a smelly washer. I'd have them get some Spray 9, pour about two cups of it into the dispenser and do a hot wash/warm rinse cycle.w/out any clothes. Then, leave the door and tray ajar overnight. After that,they kept it open when not in use. The.dispute with Whirlpool should be dropped because the reasoning is more customer error or misuse. Not the fault of the manufacturer. Read the use and care guides. They'rethere for a reason.
