The only issue with front loader washers is that it is difficult to keep them dry on the inside when not in use. This often causes mold to develop in the door seal. You have to wipe them down after use and keep the door open for a while after use. If you don’t, mold may develop along with a foul smell.

I am also not totally convinced that they clean as well as the top loaders. They don’t seem to agitate the clothes as much. They are supposed to cause less wear and tear on the clothes though. We have both in our house and I always use the top loaders. I can’t remember the makes and models though.
