Aj, just wanted to pass along some info that I discovered last week on this very same model. I found the belt badly burned like that , so I replaced it and left after checking the spin cycle. A week later the customer called back to report the machine not spinning. Upon my return I noticed that his drain hose was clamped off into a 3/4" Pipe going into the drain which was stopped up.
It began to make sense to me then why the belt burned off in the first place....this machine begins a spin cycle full of water, allowing the belt to slip slightly until the pump can draw off the water in the tub. With a blocked drain, the belt was constantly turning a full tub of water without any relief. This customer ended up having to do a major sewer cleanout and fixing his drainpipe back to a normal installation without the use of clamps due to a backup. Folks should ensure that their drain hose is not kinked and the machine empties the tub in 70 second or less after replacing a belt. Learn something new every day
