Just had teck go back out yesterday and was going to give more info.
He did hear water in top ring ( we were thinking that also), he said that it will start to spin when draning and that when all the water is out it starts to bang off balance really bad.
Make sure unit is draining properly and that tub is engaging and disengaging during transition from wash to spin.
not sure about this, are they suppose to start-stop-start-stop for a while?
Sorry not sure why filling with water would make it off balance at spin cycle?
so you only changed the suspension balls, not the actual rods with the springs on them...i find them to be the culprit alot of the time
I thought about this one today before I got home, going to see what others think also.
Thanks so much you guys and gals for you help I love this site
