GE top load washer doesn't spin

Hi All,

I have a GE too load washer where the drum doesn’t spin. The motor spins and there was a burning smell so I replaced the belt (belt was worn out on inspection after removing). I reset the motor and tried running it again but have the same result, the motor spins but not the belt. The drive pulley from the motor spins but the belt around it doesn’t. What should I look at next? I was thinking maybe the idler pulley is not providing enough belt tension.

Thanks.
