Ninja Specialty CM407 Brewing Machine: Common Problems and Their Causes
Before diving into the solutions, let’s explore some of the most common issues you might encounter while using the Ninja Specialty CM407. These problems can stem from simple mistakes or regular wear and tear.
Coffee Maker Not Turning On
Possible Causes:
- Power Connection Issues: The coffee maker may not be properly plugged into the electrical outlet.
- Faulty Power Button or Plug: There could be an issue with the power button or the power plug.
- Internal Fuse or Circuit Issue: If the machine still does not turn on after checking the power source, an internal fuse or wiring problem might be the culprit.
Brew Cycle Issues
Possible Causes:
- Brew Cycle Stalls: If the coffee maker’s brew cycle stops halfway, it could be due to water reservoir issues or a clogged filter.
- Coffee Overflowing: Overfilling the water reservoir or using too much coffee grounds can cause overflow in both the brew basket and the cup.
Coffee Too Weak or Too Strong
Possible Causes:
- Incorrect Coffee Grounds Amount: Too few or too many grounds in the brew basket can affect the strength of the coffee.
- Brew Setting: The Classic Brew may yield weaker coffee compared to the Rich Brew setting.
- Grind Size: If you’re using very fine coffee grounds, it may cause the coffee to be too strong or lead to overflow.
Ninja Specialty CM407 Coffee Brewer: Step-by-Step Troubleshooting Solutions
Now, let’s dive into the specific problems and the steps to resolve them.
1. Power-Related Issues
If your Ninja Specialty Coffee Maker isn’t turning on, follow these steps:
Check the Power Supply
- Step 1: Ensure the coffee maker is properly plugged into a working electrical outlet.
- Step 2: Check the power cord for any visible damage. If damaged, replace the power cord.
- Step 3: Press the power button and check if the unit responds. If it still does not turn on, try plugging the coffee maker into a different outlet to rule out a faulty socket.
Internal Circuit or Fuse Issue
- Step 1: If the above steps don’t resolve the issue, there may be an internal circuit problem, such as a blown fuse. Contact Ninja Customer Service at 1-877-646-5288 for repairs.
2. Brew Basket Overflowing
An overflowing brew basket can make a mess and interrupt your brewing process. To prevent this, follow these steps:
Adjust Coffee Grounds Amount
- Step 1: Check if you’re using a medium grind coffee. If your coffee is too fine, it can clog the filter and cause the brew to overflow.
- Step 2: Ensure that you’re using the appropriate amount of coffee grounds for the size of the brew. The Ninja Smart Scoop™ or the provided chart should be followed for accurate measurements.
Check for Clogs
- Step 1: Remove the filter holder and inspect the filter basket for any blockages.
- Step 2: If you find a clog, clear it by washing the filter holder with warm, soapy water.
Don’t Overfill the Water Reservoir
- Step 1: Make sure the water reservoir is not filled past the Max Fill line.
- Step 2: If you overfill, the coffee may spill over during brewing.
3. Coffee Maker Leaking
If you notice water or coffee leaking from your Ninja Coffee Maker, follow these troubleshooting steps:
Check Brew Basket Assembly
- Step 1: Make sure that the brew basket is correctly placed and the drip stop is in the closed position when not in use.
- Step 2: If the leak is coming from the brew basket, ensure the filter holder is securely inserted into the basket.
Check Water Reservoir Valve
- Step 1: After removing the water reservoir, check if water is left in the valve. This can be cleaned with a dry cloth.
Internal Leak
- Step 1: If the leak persists, there may be an issue with the internal components, and you may need to contact Ninja Customer Service for further support.
Descaling Process and Maintenance
Regular cleaning and descaling are essential for maintaining your Ninja Specialty Coffee Maker. Not only will this improve its lifespan, but it will also enhance the taste of your coffee.
Cleaning the Coffee Maker
Proper cleaning ensures optimal performance. Here’s how you can clean different parts of the coffee maker:
Water Reservoir
- Step 1: Empty the water reservoir after each brew.
- Step 2: Hand-wash it or place it in the dishwasher for thorough cleaning.
Carafe and Brew-Through Lid
- Step 1: Wash the carafe and brew-through lid with warm, soapy water. Avoid using abrasive materials like wire brushes to prevent damage.
Permanent Filter
- Step 1: If using a permanent filter, wash it thoroughly with warm water and soap after each use.
Frother Whisk
- Step 1: After frothing, clean the whisk by twisting it out and washing it under warm water.
Descaling the Coffee Maker
Descaling helps to remove calcium buildup that can affect the coffee maker’s functionality.
Steps to Descale:
- Fill the Water Reservoir: Add 16 oz. of white vinegar and fill the rest of the reservoir with water up to the Max Fill line.
- Press the Clean Button: Select the Full Carafe size and press the Clean button. The machine will start the cleaning cycle.
- Flush the System: Once the cleaning cycle is complete, run one or two more cycles with just water to flush out the vinegar solution.

The Ninja Specialty Coffee Maker will display error messages to alert you of issues. Here are the most common error codes and how to fix them.
“Add Wtr” Message

FAQs
Why is my coffee brewing too slowly?
This can happen due to several factors, including overuse of coffee grounds, a clogged filter, or insufficient water in the reservoir. Check the amount of grounds and clean the filter basket to resolve the issue.
How can I make my coffee stronger?
To get a stronger brew, use the Rich Brew setting, or add more coffee grounds to the filter basket. You can also choose darker roast beans for a bolder flavor.
Why is there sediment in my coffee?
If using a permanent filter, finely ground coffee may result in sediment. To avoid this, use a medium grind or a paper filter instead.
