Hoover blown fuse, Series ZF12.0, Model U5194-900?

How can I find & replace the fuse? I was routinely vacuuming & it simply cut off. I thought I must have blown a house fuse but that turned out to not be true. The on/off switch has no effect, no matter where I plug the vacuum in, including A/C outlets I test. This model is called the "Mach 5 Multi-Chamber Cyclonic" vacuum. It is about 6 months old. Any pointers on where the fuse is located within the vacuum would be greatly appreciated.
