Ninja Coffee Bar® Single-Serve System
I tried to start a brew cycle and my Ninja Coffee Bar® is beeping.
If your unit beeps five times when you attempt to initiate a brew cycle, there are two common reasons:
  • The drip stop is in the closed position. Toggle the drip stop to the open position, and re-select your brew size and type to start the brew again
  • There is no water in the reservoir. Fill the water reservoir up to, but not exceeding, the Max Fill line, then re-select your brew size and type to start the brew again

If your Ninja Coffee Bar® is still beeping, it may be time to run the Clean cycle. Please refer to the "How to clean & descale your Ninja Coffee Bar®" FAQ under Product Care.

My Coffee Bar just started to make coffee by itself and it spilled everywhere.
The drip stop is open. Close it by moving the drip stop tab on the brew basket to the closed position denoted by a water droplet icon with a slash through it. If this does not stop the brew, unplug the brewer.

I didn't get as much coffee as I should have.
Ensure that you have the correct size container for the program you have selected rich brew and ice brew will yield smaller and more concentrated amounts. The voltage in your home's electrical system and the type of water used can influence the amount of coffee the Ninja Coffee Bar® will yield. Hot water and/or high voltage will yield slightly less coffee, and cold water and/or low voltage will yield slightly more coffee.

My brew cycle is taking too long.
The Cup setting will take approximately 4 minutes to brew.

If the brew cycle is taking longer than normal, run a Clean cycle with the descaling solution.

The brewing cycle produced less coffee than expected.
Before brewing, make sure the Drip Stop toggle is set to the open position, denoted by the water droplet image, and the Clean light is off. If your brew cycle is not completing, it may be time to clean and descale your machine. Refer to cleaning instructions.

Before removing your cup, make sure you allow the Ninja Coffee Bar® to complete its full brew cycle. It will beep when finished. Each brew has a pre-infusion cycle with varying times. The brew will begin, stop, and be quiet for a short period of time before it begins again. This process is used to evenly saturate the coffee grounds.

For a single cup on Classic Brew, we recommend using a 12 oz. cup. The extra space ensures that you can comfortably add cream/sugar and carry your cup without spilling. Use a 14 oz. cup for XL Cup; a 16 oz. vessel for Travel Mug; and a 20 oz. vessel for XL Multi-Serve. Note that Rich Brew and Over Ice Brew will yield smaller and more concentrated amounts than Classic Brew.

Be aware that coffee grounds absorb water during normal operations; using more than the recommended amount of coffee grounds will result in less coffee. For the best experience, we recommend using the double-sided Ninja Smart Scoop, with no more than 3 small scoops (3 tbsp.) for Cup/XL Cup or 5 small scoops (5 tbsp.) for Travel/XL Multi-serve.

The voltage in your home's electrical system and the type of water used can also influence the amount of coffee the Ninja Coffee Bar® will yield. We recommend using cold water, as putting hot water directly into the water reservoir will yield slightly less coffee. High voltage will also yield slightly less coffee. Try moving to a different outlet, especially if you have an older electrical system in your building.

I didn't put in enough water, and my Ninja Coffee Bar® started beeping in mid-cycle. Can I just add more water and keep going?
To ensure the best possible coffee, a new brew cycle is needed. Refill the water reservoir to the correlating fill line for your brew size, or up to, but not exceeding, the Max Fill line. Empty the brew basket and the brewing vessel. Place the empty vessel beneath the brew basket, insert fresh coffee grounds in the brew basket, and start your brew cycle again.

Is it normal for the brew type button to pulse while the Ninja Coffee Bar® is brewing?
Yes, when the Ninja Coffee Bar® is brewing, you will notice that the brew type you have selected will be illuminated and pulse on and off during the brew.

My brew cycle will not start.
Make sure the unit is powered on, and the display is illuminated. If there are no lights, it means the machine is not getting power. Try a different outlet and press the Power button. Check to make sure there is water in the water reservoir.

Make sure the Drip Stop is open, as the machine will beep 5 times and the brew cycle will not start if the Drip Stop is in the closed position. If the Drip Stop LED is illuminated, and the Drip Stop is in the open position, it means the brew basket was inserted incorrectly. Reinsert the brew basket by aligning it with the rails, then slide it into the brewer until it clicks in place.

If your Ninja Coffee Bar® beeps 5 times, this could indicate that there is not enough water in the reservoir. Please refill the water reservoir, and reselect your brew size and type to restart the brew cycle.

If the above actions have not corrected the beeping, it may be time to run the Clean cycle. Please refer to the Care & Maintenance section.

NOTE: The brew will begin, stop, and be quiet for a short period of time before it begins again. This pre-infusion process is used to evenly saturate your coffee grounds.

My coffee still isn't hot enough.
Try these tips:
  • You can program the Warming Plate to stay on longer when brewing a Half or Full Carafe. Simply press and hold the Stay Warm button and use the hour (H) or minute (M) buttons to select the length of time you wish to have the Warming Plate remain on.
  • When using a ceramic cup, we recommend preheating the cup by running it under hot water from the sink. When using a travel mug, put the top on as soon as the brew cycle is completed.
  • When using the glass carafe, ensure the brew-through lid is on correctly and securely fastened. This helps maintain the carafe's temperature. Not using the brew-through lid, or not having the lid on properly, could allow heat to escape from the carafe, causing the coffee to cool rapidly.

My cup or travel mug overflowed.
The Ninja® Coffee Brewer is designed to deliver the following amounts on Classic Brew:
  • Cup - 9.5 oz.
  • Travel - 14 oz.

If your cup overflowed, please be sure that the cup can hold over 12 oz. of liquid, and your travel mug can hold over 16 oz.

NOTE: On Rich Brew and Over Ice Brew there will be less volume dispensed.

If your Ninja® Coffee Brewer has gradually increased the volume dispensed, we recommend running the clean cycle with a descaling solution specifically formulated for coffeemaker cleaning.

My Ninja Coffee Bar® started beeping right after I tried to start a brew.
If there is no water in the reservoir tank, refill with the appropriate amount of water, and start a new brew cycle.

If there is water in the tank and the LED drip stop light is illuminated, then the drip stop is on. If a brew cycle starts with the drip stop on, the Ninja Coffee Bar® will start to beep after 20 seconds and will continue until the drip stop is opened, or six minutes has passed, at which time the brew will be canceled.

Turn off the drip stop by moving the tab on the brew basket to the open position, denoted by the image of the water droplet. Once the drip stop is open, start a new brew cycle.

If these two steps have not resolved the issue, run a Clean cycle by following the directions in the "How to clean & descale your Ninja Coffee Bar®" FAQ under product care.

The water reservoir is leaking.
Water may drip from the reservoir when it is removed. Not to worry, this is a normal occurrence. Simply use a dry cloth to wipe away the water droplets from the machine after it has cooled.
Do not over-fill the water reservoir. Fill the water up to, but not exceeding, the Max Fill line.

The brew basket is overflowing—water and/or coffee grounds are coming out of the top and down the sides.
The bottom opening of the brew basket is clogged. This can happen with finely ground coffee, or if too many coffee grounds were put into the basket. Remove the basket carefully, discard the coffee grounds, and rinse the entire brew basket (and permanent filter, if applicable) with water to remove any grounds remaining inside. Do NOT touch the basket until it has completely cooled, as the water will be very HOT. Clogging of the brew basket can also occur when using the permanent filter in conjunction with a paper filter. When using a paper filter, do not also use the permanent filter.

The paper filter is folding over when I put the brew basket in the Ninja Coffee Bar®.
The Ninja Coffee Bar® is designed to take a #2 cone filter. Be sure you are using this size and shape, as larger sizes may fold over. If not, allow the brew basket to cool before handling. The paper filters are thicker on two edges. Fold those edges along the crease (once along the bottom and once along the side) before inserting into the brew basket. Alternatively, you can wet the sides of the paper filter to temporarily adhere it to the brew basket.

NOTE: When using a paper filter, do not also use the permanent filter.

There is "mud" or sediment in my coffee.
If using a permanent filter, the sediment at the bottom of the brewed coffee may be due to using finely ground coffee. To reduce the amount of sediment in the brewed coffee, use a slightly coarser grind, or use a paper filter.

There is no water coming out of the bottom of the brew basket into my cup.
If the drip stop LED light is illuminated, then disengage by moving the drip stop tab on the brew basket from the closed position to the open position, denoted by the icon of a water drop with no slash through it.

The bottom opening of the brew basket may be clogged. This can happen with finely ground coffee, or if too many coffee grounds were put into the basket. Remove the basket carefully, discard the coffee grounds, and rinse the entire brew basket (and permanent filter, if applicable) with water to remove any grounds remaining inside. Do NOT touch the basket until it has completely cooled, as the water will be very HOT. Clogging of the brew basket can also occur when using the permanent filter in conjunction with a paper filter. When using a paper filter, do not use the permanent filter.

The Ninja Coffee Bar® is equipped with Auto-iQ technology that includes a pre-infusion feature. This means there will be a short delay after you start your brew cycle where water is saturating with your coffee grounds in the brew basket to enhance the flavor of the coffee.

If problem persists, please wash out your brew basket and run a Clean cycle.

There is water left in the reservoir.
After a brew, you may notice leftover water in your reservoir after filling to the minimum fill line of the size selected. The water reservoir markings are minimum fill lines that indicate if there is enough water for the proper brew size in the reservoir, but all brew styles use different amounts of water to create the proper flavor and concentration. Auto-iQ One-Touch Intelligence will only use the water needed for the brew size and style selected. Please note that the system is designed to always leave some water remaining in the reservoir after a brew. This to protect the boiler from boiling dry, and helps extend the life of your machine.

Why is my Over Ice Brew not cold?
The Over Ice Brew is designed to brew hot coffee over ice to lock in the flavor for rich, smooth iced coffee. Make sure your cup, travel mug, or carafe is filled all the way to the top with ice cubes.

We strongly recommend using ice cubes when making iced coffee. Shaved and crushed ice have different packing characteristics. Because of this, you should NOT use shaved or crushed ice, as the vessel used may overflow once coffee is brewed over the ice.

IMPORTANT: DO NOT use hot water in the water reservoir. We recommend cool, fresh, filtered water.

My unit beeps, but the brew cycle will not start.
There are a few reasons why the unit will beep, but a brew will not start:
  • Ensure the display is illimunated. If there are no lights illuminated, it means the machine is not getting power. Try a different outlet.
  • Check the Drip Stop, and make sure it is set to the open position (denoted by the image of a water droplet).
  • Ensure the brew basket is properly inserted and aligned.
  • Ensure there is water in the reservoir. If there is no water, and the boiler is too hot, the unit will beep and not start the brew in order to protect the boiler from overheating.
  • If the boiler has become scaled from excessive hard water usage without cleaning and got too hot, the unit will beep and not start the brew in order to protect the boiler from overheating. Please run a Clean cycle, following the instructions in the Owner's Guide or under the FAQ titled "How to clean and descale your Ninja Coffee Bar®."
