Macerator pum not working

[jimmyr5]

Hi All:
I have a 2014 R5 with a Jabsco Head. When I put the boat away for the winter every thing was working fine. The first time i tried to use it this season the pump dose not start. Its like there is no power to it. So before I start taking thing apart I would like to know if anyone has had this problem. also I didn't see a breaker for the Macerator there must be one just don't now were.
Thanks Jim
