After years of owning only DD Whirlpool machines, I purchased a LG WM8100HVA front loader. I like the machine so far, but I'm wondering if something is wrong with it. More often than not, it has a real hard time balancing itself to the point where the tub hits the side of the machine and I can watch it bow out. I'm new to front loaders and the tub itself seems to be able to move around quite a bit front to back. Also, I can push down and deflect the back of the tub some too. Not so much on the front of it. The first thing I did was was make sure it was level and it is. Anything else I should be looking at? Is it normal to have the tub move this much? I don't want to end up damaging it running it like this. Sometimes it works completely fine too. Than you in advance for any advice you have!
