Why Is Keurig Not Pumping Water? 4 Easy Fixes

You’re one step away from a hot cup of coffee…

But then you realize your Keurig coffee maker is not pumping water.

Let me stop you before you start panicking.

In most cases, the reason for Keurig not pumping water lies in something that’s easy to fix.

Today, we’ll go over the most common reasons why your machine might be acting this way, as well as how to fix it.

Let’s dive straight in.

Keurig Not Pumping Water: The Problems & Solutions

Your Keurig machine is making noise but not actually pumping water through?

There are several different issues your coffee maker might be experiencing. 

Water Line and Filter are Clogged

Both tap and bottled water contain minerals such as calcium and magnesium.

Over time, these minerals build up inside your coffee maker, creating a layer of a hard, chalky substance called limescale.

Keurig machine feature a fine mesh screen filter that sits where water leaves the reservoir and flows into the water line. This little thing is designed to remove impurities from the water as it flows through the machine. 

But after prolonged use, the filter itself can get clogged from too much debris. 

If that happens, there are a few things you can do.

First, try this:

  1. Unplug the machine from the wall and remove the water tank. 
  2. Remove water from the tank, then take out the filter. For this, you’ll need a long magnetic screwdriver. There are three screws that hold it in place that you need to remove.
  3. Once the screen filter is out, let’s clean it. You can do that by soaking it either in soapy water or vinegar for about 45 minutes. 
  4. If the debris is not 100% gone from soaking, you’ll need to clean it manually. For this, you can use a toothbrush under a strong flow of tap water. Alternatively, you can use Waterpik oral irrigator to force a stream of water through the screen to remove limescale remains.
  5. When you’re done cleaning, do an additional fresh water rinse to make sure the entire filter is unclogged.
  6. Put the filter parts back together and screw the entire thing back into its original position.

If you’ve recently descaled and cleaned your machine, then the limescale buildup might not be too big. In that case, there might be a quicker and easier fix for your problem.

  1. Grab a baster pipette and insert it where the water tank meets the water line. 
  2. Force water through it a couple of times. The water should get murky as you force the limescale through.

In the case of slight debris buildup, this should do the trick.

There is Air in the Water Lines

Sometimes, the air can get stuck inside water lines. In that case, we need to get things shaking!

No, I’m not kidding. You’ll have to rock your machine to get the air out.

Here’s how:

  1. Unplug the Keurig brewer from the wall outlet. 
  2. Disassemble the water tank and the drip tray. 
  3. Grab the coffee maker with both hands and shake it like a bartender making a cocktail. I know it sounds weird, but shaking movement should release the trapped air inside the water lines.

Another thing you can do to remove stuck air bubbles is to turn the coffee maker upside down and smack it.

Alternatively, try this:

  1. Open the water tank lid.
  2. Close the water line with your finger.
  3. Check out the pod chamber to make sure there’s no Keurig K Cup inside the K Cup holder.
  4. Lower the handle and run a brew cycle with just water, with your finger still on the water line.

What this will do is it will force the water to flow through the line and push the air bubbles out.

Whichever method you decide on using, always make sure there’s no leftover hot water inside the machine. To be extra safe, unplug the coffee maker at least an hour before doing anything. 

Keurig Water Pump is Damaged

Not to sound pessimistic, but one possible reason why your Keurig coffee maker might not be working could be because the water pump got damaged.

And if that happens, the only thing you can do is replace either the motor or the whole thing. In that case, make sure you get the right part for your Keurig model.

“More Water Please” Error

If your Keurig sends out this error, there are two possible causes for this. First, the water you’re using might not be adequate. Keurig coffee brewer can be quite sensitive to the type of water you put inside. This is especially the case with distilled water.

Alternatively, your water tank might simply be sending incorrect signals.

Whichever it is, you can easily fix this error.

Here’s how:

  1. Remove the water tank from its designated spot. Pour any leftover water into the sink, then refill to the optimal level line. 
  2. Try running the machine. If it still doesn’t work, follow the next steps.
  3. Take out the water tank and pour out the water.
  4. Clean the inside of the water tank with a non-abrasive cloth. 
  5. Refill the water tank with clean water and put it back into its designated place.

In most cases, this should solve the issue and you are ready to brew coffee.

What to Do if Your Keurig Continue Not Pumping Water?

You’ve tried everything from the list, and your Keurig coffee maker is still not pumping water?

Unfortunately, there isn’t much else you can do yourself, aside from contacting customer service. They should guide you through possible fixes, step by step.

At the very least, Keurig customer service should tell you if they can repair your coffee maker or even replace it under warranty. 

FAQ

Still have some questions regarding Keurig troubleshooting? Here are the answers to some questions regarding the Keurig coffee maker you might want to know.

How do you reset a Keurig after descaling?

Resetting a Keurig machine is rather simple.

Unplug the machine from the wall outlet and remove the water tank. Let it rest for at least an hour. After the time is up, reattach the water reservoir and plug the Keurig back in.

Can you run vinegar through a Keurig to descale it?

Yes, you can, although there is a dedicated Keurig descaling solution. Ideally, you want to make a mixture of a 1:1 water to vinegar ratio. To descale your machine, add the mixture directly into the water reservoir, then run a couple of water-only brew cycles (without coffee grounds).

What does it mean to prime a Keurig?

If your Keurig coffee machine is showing a prime error message, this means that water isn’t flowing properly from the water reservoir. When this happens, the machine won’t brew. Luckily, in most cases, the reason for the prime message is one of the mentioned above.

To Sum Things Up

If your Keurig won’t pump water, that’s probably because there’s something blocking the water flow. 

In most cases, the problem lies either in the mineral buildup on the water filter or air bubbles inside the water line.

However, sometimes the reason is mechanical. In that case, it can only be fixed by changing the broken part or the entire machine.
