Your Keurig indicating that you should add water, especially when the tank is full, is a fairly common issue. You can resolve this problem effectively by cleaning, resetting, filling, and properly placing the water reservoir on the Keurig. Also, try descaling, using filtered or bottled water, or blowing air into Keurig’s overflow pipe.
1. Fill the Water Reservoir to the Required Line
First things first:
Is your water reservoir actually sufficiently filled? It doesn’t hurt to double-check.
We all know that:
If your water reservoir is not sufficiently filled, the Keurig sensor will detect it and indicate this by telling you to add water.
Fill your reservoir with filtered water to the dotted line marking the maximum capacity.
Are you done?
Now that we are certain your reservoir is full, if your Keurig is still saying “add water, ” we have some other tips for you.
2. Clean and Reset the Water Reservoir and Ensure It Is Properly Placed
Here’s the thing:
If your Keurig says “add water” even after you’ve confirmed that the water reservoir is filled sufficiently, it might be a calibration issue.
The water reservoir may be improperly placed such that the Keurig does not recognize that it is full.
To fix this problem, you must ensure that the water reservoir is correctly aligned with the base of the Keurig coffee maker.
Here’s what to do:
Detach your Keurig’s water reservoir from the machine, drain it and clean it manually with dish soap. Note that not every Keurig water reservoir is dishwasher compatible.
Refill the tank with filtered water and attach it properly back onto the base of your Keurig. After doing this, the “add water” notification should disappear.
Unplug your Keurig before moving the water reservoir around to reset the machine.
3. Descale Your Coffee Maker
Another likely reason your Keurig might be asking you to add water to it is because of a clogged system.
The build-up of mineral compounds, coffee grounds, foil, and other debris gets lodged in your Keurig’s system and disrupts water flow.
The solution to this problem is descaling your Keurig. It is not a complicated procedure, and you can easily carry it out.
To descale your Keurig:
Fill your Keurig water reservoir with a mixture of Keurig descaling solution or white vinegar and water. Then, run a brew cycle to flush the system, collecting the water in a mug on the drip tray.
Leave the solution in the reservoir for a while to decimate the compounded limescale.
Discard the solution and the water collected in the mug and clean the reservoir thoroughly with dish soap.
Run several rinse cycles with plain water and no K-Cup pod to eradicate residual debris and ensure your Keurig is fully unclogged.
Descale your Keurig regularly to prevent malfunctions and enhance the quality of your brewed coffee.
4. Avoid Using Distilled or Unfiltered Water for Your Keurig Coffee Maker
Not everybody knows this but:
The water you use for your Keurig coffee maker is very important because they are sensitive to the precise type of water used. More specifically, Keurigs do not function well with distilled water.
The Keurig has a magnet in the water reservoir that serves as a sensor for detecting water levels. This sensor requires some degree of solid matter in the water for the electrical current to work.
Distilled water has little to no solid matter, so the sensors do not recognize it, and your Keurig assumes the tank is empty. This explanation could be why you are receiving the “add water” message.
To resolve this:
Ensure that you use filtered or bottled water instead. Avoid distilled or spring water for your Keurig coffee machine to prevent the “add water” error from occurring.
Using unfiltered water instigates the collection of mineral deposits and debris in your Keurig, limiting your device’s longevity.
5. Blow Air into the Overflow Pipe
After attempting all our suggestions above, your Keurig should stop notifying you to add more water to it.
If none of our suggestions seem to work for your Keurig, you should try this crude hack. It is unofficial and unusual, but it works, and your Keurig should be back to normal after trying it.
Off the record:
It would help if you filled the reservoir halfway with filtered water, then blew air into the overflow pipe for about 10 to 15 seconds. It gives the device a kickstart as the air pressure clears any internal obstruction.
If absolutely nothing works, contact Keurig customer support for assistance.
