What to do if “Err” appears on the Ninja Kitchen Appliances display screen?
- RrussellpamelaAug 5, 2025
If the Ninja Kitchen Appliance displays 'Err' on the screen, it means that the power to the unit was interrupted, or the function dial is not in the “OFF” position. To resolve this, turn the function dial to “OFF” and then turn the dial to your desired cooking mode. If the error persists due to a prolonged power failure, dispose of the food.
