On the glass carafe version, the HOT SURFACE indicator is a safety feature that illuminates when the warming plate is hot. The HOT SURFACE indicator will remain on until the warming plate has cooled to a safe temperature. Do not touch the surface when this light is illuminated. There is no warming plate on the thermal carafe version.
We recommend cleaning the glass or thermal carafe with warm, soapy water. If you want to clean the carafe more thoroughly, we recommend using a soft foam brush. Do not use a wire brush. The glass carafe and brew-through lid are top-rack dishwasher safe. Please note that the thermal carafe is NOT dishwasher safe.
The water reservoir markings are minimum fill lines that indicate the amount of water needed for that brew size. However, all brew styles use different amounts of water to create the proper flavor and concentration, so occasionally some water may remain in the reservoir.
Each size and brew type produces a different amount of coffee to optimize strength and taste. For example, Rich brew will yield less coffee than Classic brew, while Over Ice produces a concentrated amount of coffee that drips over ice to create an iced coffee that's never watered down. Specialty brew will always produce 4 oz. of coffee.
Once the brew cycle is complete, move the drip stop to the closed position (denoted by the image of a water droplet with a slash through it) before removing your brewing vessel to avoid drips.
Ensure your cup, travel mug, or carafe is filled all the way to the top with ice cubes before brewing. The unit will brew at elevated temperatures to lock in the best flavor, then the ice will cool the brewed coffee or tea to the perfect temperature.
The thermal carafe has double"walled insulation, which keeps heat locked inside. The insulation barrier means the heat from the warming plate will not reach the inside of the carafe or affect the temperature of the coffee.
No, a paper filter and the permanent filter should NOT be used together when brewing coffee. Using both the permanent filter and a paper filter may result in clogging or water and/or coffee backing up in the brew basket.
We recommend using a descaling solution made specifically for coffeemaker cleaning. You can purchase our descaling solution at www.ninjakitchen.com. You may also use white vinegar.
A medium grind coffee is recommended. The brew basket is designed to fit a #4 cone paper filter. Note: Some models come with a permanent filter and should not be used with a paper filter.
No, you use the same amount of coffee for each brew style selected. Each brew style is designed to make the strength you need using the measurements denoted on the Ninja Smart Scoop.
Yes, we recommend using the brew-through lid as it helps maintain the carafe temperature, and to deliver optimal flavor. If the lid is not used, or is not properly in place, heat could escape from the carafe, causing the coffee to cool rapidly.
