Thank you for your inquiry. Remove the mat from the platter and turn it until one of the large holes is at the 2 o’clock position. You will see what looks like a white plastic pulley. Make sure the belt is NOT around this because it is not a pulley. Then turn the platter until one of the holes is at the 10:00 o’clock position and you should see a brass pulley. This is the motor pulley, so make sure the belt is around this pulley and well seated into the groove. Replace the mat. If this does not resolve the issue you may have a service issue.
