Before buying a replacement try this: press the RESET button on your kitchen outlet or the breaker, since GFCI outlets can silently trip. Make sure the pitcher is twisted fully into the base and the lid is clicked on - many blenders won’t power unless both are locked. Check for any shipping spacer under the jar and see if there’s a tiny reset switch on the bottom of the motor base. If none of that helps, it’s probably a warranty issue, so a quick call to the maker should get you a free swap.
