Greetings!

I've got a GE washer/dryer combo at home and for some reason, the drive belt repeatedly dropped off the pulleys.

initially when the washer stopped spinning in the middle of wash cycle, i followed this video to find out the belt has dropped, after I put it back, it worked for a month and then belt came off again. this repeatedly twice in the past week and I'm thinking maybe there's some other reason why this happens.
