Keurig Add Water Light Not Coming On: Troubleshooting and Fixes

Keurig Troubleshooting

Are you facing a morning dilemma with your Keurig coffee maker, where the Add Water light refuses to come on, leaving you puzzled and caffeine-deprived? You аre not alone. This common issue can disrupt your daily coffee routine, but fortunately, it’s often easy to fix.

In this article, we will explain why the Keurig Add Water light is not coming on and offer solutions to get your machine back in action. Plus, we will share some prevention tips to help avoid future hiccups.

Let’s start!

Why Is The Add Water Light Not Coming On?

Keurig Add Water Light

The Add Water light on your Keurig coffee machine is a helpful indicator that lets you know when the water reservoir needs a refill.

If it is not lighting up when expected, here are a few potential reasons:

  • Sometimes, the reservoir might have just enough water to not trigger the light, but not enough to brew a cup. It is a fine line.
  • The sensor that detects the water level could be malfunctioning or obstructed, preventing the light from activating.
  • Like any electronic device, Keurigs can experience software or hardware glitches that affect their indicators.
  • If the water reservoir is not properly seated, the machine might not detect its presence or water level accurately.

What To Do If The Add Water Light Is Not Coming On?

Now that know what is possibly causing the problem, let’s tackle the solutions:

Check And Refill The Water Reservoir

Before you start with more complex troubleshooting, pay attention to the basics: the water level. Your Keurig is designed to alert you when water is low, but sometimes, the sensor needs a bit more water to trigger the light.


Remove the reservoir, check the water level, and if it is low, fill it to the max line. Sometimes, simply repositioning the reservoir after filling can help the machine detect water more accurately.

Properly Align And Seat The Water Reservoir

A misaligned or improperly seated water reservoir can prevent your Keurig from detecting water levels correctly. As a result, this might stop the Add Water light from activating.


Remove the water reservoir and check if there are any signs of damage or misalignment. Carefully clean the base and the machine’s contact area, then reattach the reservoir. Make sure it clicks into place securely. This can help re-establish a good connection and proper sensor function.

Clean The Water Level Sensor

Dirt, coffee grounds, or mineral deposits can obstruct the sensor responsible for detecting water levels, affecting the Add Water light functionality.


Locate the water level sensor in your Keurig (usually found in the reservoir area or at its base). Gently wipe the sensor with a soft, damp cloth to remove any buildup. For mineral deposits, a diluted vinegar solution can help. Rinse thoroughly with water after cleaning to prevent any vinegar taste.

Reset Your Keurig Coffee Maker

Reset Your Keurig Coffee Maker

Electronic devices can sometimes benefit from a simple reset, which clears temporary glitches or software issues that might be affecting the sensors or lights.


Turn off your Keurig and unplug it from the power source. Wait for about 5 minutes before plugging it back in. This can reset the system, potentially resolving any minor electronic issues. Turn the machine back on and check if the issue has been resolved.

Contact Keurig Customer Support

If you have tried all the above solutions and the Add Water light still refuses to come on, it might indicate a deeper issue with your coffee maker.


Contact Keurig customer support for professional advice. Make sure to have the model number of your coffee machine readz. They may offer additional troubleshooting tips, repair options, or information on warranty coverage.

Prevention Tips

To keep your mornings running smoothly, consider these preventative measures:

  • Keep your Keurig clean, including the water reservoir and sensor area, to prevent buildup that could interfere with machine functions.
  • Always make sure that the water reservoir is placed properly and filled to the recommended level before brewing.
  • Use filtered or bottled water to reduce the risk of mineral buildup inside the machine, which can affect sensors and overall performance.
  • Follow the manufacturer’s guidelines for descaling and maintenance to keep your machine in top condition.

Frequently Asked Questions

Preventive measures include regular cleaning and descaling, using filtered water to minimize mineral buildup, and making sure the water reservoir is always properly aligned and securely attached.

What should I do if cleaning the water level sensor doesn’t fix the Add Water light issue?

After cleaning the sensor, if the Add Water light still doesn’t come on, try resetting your Keurig by unplugging it for a few minutes. If this doesn’t work, it might be a more complex electrical issue, and you should contact customer support.


When the Add Water light fails to come on, it can be a minor problem in your coffee journey, but you can easily fix it with a bit of troubleshooting.
