Hi Yvonne, here is a link to the user manual, you can either print the pages, or save it on your computer for future use.
Please check the trouble shooting part. but what usually fails in this case is the motor brushes, but since yours is so new it may be the safety switch.
Also the issue could be that the motor is just stuck you can tap it a bit with a rubber mallet, make sure the unit is unplugged first!
And tap at the back end on top, not hard enough to cause damage to the casing.
Please let me know how that goes, If that doesn't work you will need to replace the motor brushes.
I can help you with where to get the parts and I will help you all the way to replace them, its an easy task.
In any case, I will stick with you until this is complete.
