Our GE washing machine would not start up and it was due to a bad drive belt. Got the replacement belt (generic) and not the right size! Got a true replacement (authentic GE part) and worked like a charm!
When you tried to put the first belt on you tried it on the wrong pulley. It should have gone on the smaller one, however, I bought the exact same belt from the same supplier on Amazon and it does not fit so I did what you did and bought direct from GE. Now we wait for delivery
