Yeah, this one's common. The brewer's smart sensing system doesn't detect a properly closed brewing path. It needs to know if you're using grounds, a pod, or just hot water.
Check these three things, in order:
- Sliding Lid: Make sure it's fully slid closed over the brew basket.
- Ninja Pod Adapter: If you're using it, ensure the handle is closed and pulled toward you until it clicks into the LOCK position.
- Hot Water Dial: Turn it completely to the coffee bean icon (for grounds/pods) or the water droplet icon (for hot water). It can't be in between.
If you've done all that and it's still blank, the sensor might be faulty. Unplug the brewer for 60 seconds, then plug it back in. If the problem persists, you'll need to call support at 1-877-646-5288.
