Troubleshooting Guide
PROBLEMS POSSIBLE REASONS & SOLUTIONS
Sediment in my coffee.
If there is sediment at the bottom of the brewed coffee, this may be due to using finely ground 
coffee in the permanent filter.
To reduce the amount of sediment in the brewed coffee use a slightly coarser grind or use a paper 
filter.
Grounds in my coffee.
If there are grounds in your coffee, check to make sure the brew basket did not overflow.
If there are too many grounds in the brew basket, or you are using a fine ground coffee, the 
grounds will flow into an overflow channel designed to make sure overflow is captured in the brew 
vessel. For best results use medium ground coffee in the recommended measurements.
Brew Basket dripping 
after brew.
Check to see if the Drip Stop toggle is set to the closed, no-drip position. 
If the Drip Stop is set to the closed, no drip position and the brewer continues to drip, run a Clean 
Cycle or wash the brew basket thoroughly with warm, soapy water.
Paper filter falling 
over.
The Ninja Coffee Bar
®
 is designed to take a #2 cone filter. Be sure you are using this size and shape 
for best results.
Be sure the paper filter is firmly pressed into the brew basket. 
Wet the corners of the filter for best results.
If problem persists, try using the permanent filter.
Coffee is not hot 
enough.
To keep your coffee hotter longer, pre-heat your mug or carafe by rinsing it with hot water from the 
tap. 
If using a microwave safe mug with cream or milk, try pre-heating the cream or milk in the 
microwave for 30 seconds.
NOTE: Never place carafe in the microwave.
Over Ice Brew is 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.
Weak coffee.
If the coffee tastes weak, try adding more coffee grounds into the brew basket for the next 
brew cycle.
If the coffee is still weak after adding more coffee grounds, try Rich Brew to make a stronger, more 
concentrated cup.
Coffee too strong.
Try using a coarser grind.
If the coffee is still too strong, try using less coffee grounds.
Brew will not start.
Make sure the  Power Save Button light is illuminated. Check to make sure the brewer is plugged in 
and water is in the water reservoir.
If the Drip Stop is in the open position, check that the brew basket is pushed all the way into the 
brewer.
If you hear 5 beeps, check that the Drip Stop is in the open position.
NOTE: 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 your coffee grounds.
Brew cycle is too slow.
A carafe brew will take approximately 8 minutes and the single cup will take approximately 4 
minutes.
If the brew cycle is taking longer than normal, run the Clean Cycle with the descaling solution.

Brew basket 
overflowed.
Check the amount of coffee or type of grind used.
Water left in my 
reservoir.
Ninja Coffee Bar allows you to fill the reservoir up to but not exceeding the Max Fill line 
and Auto-iQ
™
 One-Touch Intelligence will only use the water needed for the brew size 
and style selected.
After a brew you may notice leftover water in your water 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.
You can brew multiple cups before needing to refill.
Does it take coffee 
pods?
This brewer is designed to brew coffee grounds only. Do not insert pods or K-Cups

.
My Ninja Coffee Bar is 
leaking.
If the leak is coming from the brew basket, be sure all the parts are fit securely in the 
brewer. 
If the leak is coming from the bottom of the brewer, call customer service 
at 1-877-646-5288.
My Ninja Coffee Bar 
beeped and did not 
complete the full brew 
that I selected.
Ensure the water reservoir is locked in place and is filled with enough water for the 
desired brew. 
Check the CLEAN indicator light. If illuminated, run a Clean Cycle with the appropriate 
descaling solution or a white vinegar mixture. See Care & Maintenance section.
Check the Drip Stop indicator light. If illuminated, ensure the brew basket is fully inserted 
into the brewer and open the Drip Stop once the vessel is placed under the brew basket.
If the problem persists, please call customer service at 1-877-646-5288.
Why is the second cup 
that I brewed hotter 
than the first cup?
Once the Ninja Coffee Bar has brewed the first cup, the brewing system is pre-warmed. 
This enables any following brews to be slightly hotter. For a hot first cup, try pre-
warming your mug. Or after pugging in or turning on your brewer from Power Save mode, 
allow 3 minutes for your brewer to preheat.
