Scoop KitchenThe machine will not start or stops
Most of the time the bowl or lid is not fully locked, or the tubpint is too hard or too full. Here is what to check, in order.

3 possible causes
The bowl or lid is not locked
Most likelyHow to tell: It will not start at all, or a light blinks.
Why: The CREAMi only runs when the outer bowl, lid and paddle are locked in place. Ninja says a blinking install light means the bowl is not installed properly.
Fix this tubpint
- Twist the outer bowl until it clicks, and check the lid and paddle are locked.
- Try again.
Next time
- Listen for the click every time.
The tubpint is too hard or too full
Most likelyHow to tell: It starts, then strains, stalls or stops.
Why: A very hard or overfilled tubpint makes the paddle work much harder.
Fix this tubpint
- Let a very hard base, like sorbet or diet drinks, stand for 10 minutes, then try again.
- Scrape a tubpint that froze above the line down to below it.
Next time
- Fill only to the max fill line.
- Freeze level, and scrape any hump flat.
The wrong tubpint for the machine
Most likelyHow to tell: The tubpint or bowl will not lock at all.
Why: TubsPints only fit their own machine family. A Deluxe tubpint does not fit a 7-in-1.
Fix this tubpint
- Use a tubpint made for your machine.
Next time
- Check the model number on the bottom of the machine.

Why won’t my Ninja CREAMi start?
Usually the outer bowl, lid or paddle is not locked. Twist the bowl until it clicks. If a light keeps blinking, check your manual’s guide to the lights.
