What to do if my Ninja Coffee Maker cup overflows?
- JJames MillerAug 19, 2025
If your cup, travel mug, or carafe overflowed while using the Ninja Coffee Maker, it might be because they weren't empty before brewing or the water exceeded the max fill line in the reservoir. Ensure you're using at least a 12 oz cup for the 'cup' size and a 16 oz travel mug for the 'travel mug' size.
