Why does my Ninja Coffee Maker overflow?
- MMr. Scott CoffeyJul 30, 2025
If your Ninja Coffee Maker is overflowing, it could be due to a couple of reasons. First, make sure the cup, travel mug, or carafe was completely empty before you started brewing. Also, ensure you're using the correct size: at least a 12 oz cup for the 'cup' size, 14 oz for 'XL Cup', 16 oz for 'travel mug', and 20 oz for 'XL Multi-Serve'. Another cause might be that you filled the water reservoir past the Max Fill line before brewing. Make sure the water level is correct.
