my macerator stopped working

I'm a newbie at the forum stuff after lurking around reading others' posts. So, here goes: 4th RV, brand new 2014 ACE 29.2. During walk thru the tech says, "here's the macerator button: turn it on, pull the black then pull the grey, that's it." Sounds easy.

Very first camping trip: almost full grey tank, I pull the grey and turn on the macerator. pump hums and never changes pitch. i can see that some water is coming out (not gushing out) and then the pump stops and the switch doesn't work. I wait 10 minutes and pump will work again. next time, it works 3 minutes and cuts off. now, it won't cut on at all. No blown fuses in the box. I've opened up the macerator and confirmed the blades will turn. I bypassed the macerator and confirmed (don't ask) that both the black and grey tanks are flowing freely. I can't see anything stuck in it. Is my macerator dead? Is there another fuse someplace to check. Help.
