If it is unbalanced, it won't spin the water out properly either.
After dismantling it, I found out that the outer tub came off or disconnected from the inner tube due to rust built up. That is the reason for it spinning in the middle but not moving the tub itself.
It is broken. No doubt needs a new bearing.
Our side loading Whirlpool washing machine drain was clogged with the grand baby's socks.
You will need to change the belt. It is probably worn
It sounds like you have a fault with your machine get the manufacture to look at it of it is still insured if not you will need a new one. Hope this helps
Maybe its due to clothes overload or you filter is semi blocked not totally sure
Probably the drain pump is cloggled or defective, or the hose is kinked or clogged too. Because if spin normally I do not think the belt is the problem.
