Hi, I bought a new washer about a month ago (unfortunately Illinois is taking forever to start the cash for clunkers so I didn't get to take advantage of that since my old washer was leaking). However, I shopped around and initially thought that I wanted a front loader and ended up buying another top loader. Even the salesman at Sears that could have made a much larger commission had I bought a front loader confessed that the maintenance on the front loaders is much more time consuming and that you should always buy the maintenance agreement with a front loader because you are definitely goign to need it. He said I would need to have someone come to my home annually to maintain the front loader if I didn't want to have to have emergency service. He said if I was "handy" I may be able to do the annual maintenance myself.
I also spoke with a coworker who bought an LG front loading combo, which are supposed to be top of the line and he has been really disappointed with them. He has to leave the door open on the washer when he is not using it so that he doesn't get a mildew smell, he has to buy the more expensive laundry soap, he has had to have someone come in to maintain the washer, there was more, but I don't remember everything. Oh, he said it doesn't clean heavily soiled clothes as well, he has 3 dogs and he said when his clothes are really dirty they end up stained even if he doesn't dry them. I don't know why that is. I spoke with a friend of mine with twins that uses cloth diapers and she actually got rid of her top loader becuase she said it didn't wash the diapers properly. These complaints were echoed online.
When I asked the salesman about the mildew smell issue and having to keep the door of the washer open, which I heard about a lot, he said that some of the more expensive front loaders now come with a fan that runs when the washer isn't running to dry out the washer so mildew doesn't form. I don't know what that does to the energy efficiency of the washer. It probably still uses less water, but more electricity. The top loader I bought is an energy efficient model and it has a water senser to know how much water to use and supposedly uses less than other top loader models.
Anyway, that was longer than I planned. Good luck with your decision.
