Firgidaire GDSP4715AF0A dishwasher keeps shutting off

Brand new dishwasher. We hit start, shut the door. It runs for 5 minutes, and shuts off. Start/resume light is flashing. Pop it open, hit the button again, close the door, and it starts right up. Runs about 30 seconds then shuts off again. I’m not seeing any error codes being displayed.
