Don't know if this is the same as your problem, but I had a Kenmore washer, (made by Whirlpool) that did the same thing. It was a high efficiency model without an agitator. I finally found out that this type of washer never drains completely but always has some water left in it. This water is somewhere internal that cannot be seen unless the machine is taken apart. That water goes bad and stinks. Everything smelled like mildew and for some while my husband thought I was was washing clothes and leaving them in until they dried. I ended up having to just buy a new machine and when the stinky washer was taken away, just tilting it caused all this foul water to come out everywhere. Also I found this on the internet http://www.consumeraffairs.com/homeowners/lg_washing_machine.html
scroll down and see how other people feel about this machine. I decided that instead of buying the newest, latest, greatest, with all the bells and whistles appliances, from now on I will buy the time tested, plain jane models.
