Can a loose drum/tub of a frontloader prevent the washer from spinning/draining? Over the weekend, I first had a slow drain problem (F02). I fixed that, thanks to your website, but now the machine won't spin giving me an F06 error code. I lightened up the load and continued the wash. It started spinning again, but with a loud banging noise as it spins. After the wash, I noticed that the drum/tub is not off-centered and I cannot mannually spin the tub. Does that mean it's loose? How can I check to see if it is loose and how do I fix it?
