Keurig Coffee Maker Problems: (Machine Not Working?)

Were you just about to enjoy a freshly brewed cup of coffee only to find your Keurig coffee maker stopped working? This can be a real nuisance when all you want is a quick coffee in the morning. But with these troubleshooting tips, you can solve your Keurig coffee maker problems and get it back brewing in no time.  

Ever wondered, 'why is my Keurig not working?' It's a common question as they're responsible for a large portion of coffee maker sales. Your Keurig coffee maker has a lot of complicated parts, but most of the time, you can fix it yourself.

Let's look at some easy DIY fixes for some of the most common issues you will have with a Keurig coffee machine. These will help if your Keurig stops brewing after a few seconds or suffers any other common Keurig problems.  

1. Misassembled Parts 

If you’re wondering, ‘how do I get my Keurig to work?’, one of the most straightforward fixes for a Keurig coffee maker is correctly assembling all the parts. Every part has a specific purpose. If they're not in the right place or misassembled, then your Keurig coffee machine won't work.  

To troubleshoot each part, you should unplug your Keurig coffee machine and look at every part individually. For example, a common problem for many people is that the water reservoir isn't installed correctly. It should have a magnet holding it in place. If the water reservoir is in the right place, then the problem will be in another part. 

Missassembled parts can happen on any Keurig coffee machine, so it’s crucial to check them when troubleshooting. Examples include Keurig K Duo troubleshooting and Keurig 2.0 troubleshooting.  

2. Trapped Coffee Grounds 

The coffee grounds in Keurig problem is very common. Keurig Mini troubleshooting and Keurig K155 troubleshooting, along with troubleshooting for other Keurig machines, includes dealing with trapped coffee grounds. You can remove trapped coffee grounds by using a technique known as “burping” or “spanking.”  

You can use this technique to remove any stubborn coffee grounds or debris inside your Keurig machine. Firstly, you will need to remove the water reservoir and the drip tray. Then bring the whole device (unplugged) over to a sink or onto a plate to contain the mess. Turn the machine upside down and gently tap it a few times. This should remove residual water and any leftover coffee grounds trapped in your Keurig.

3. Clogged Needle 

The needle of a Keurig coffee maker needs to be maintained often. This is true when troubleshooting all Keurig coffee maker models, including Keurig Duo troubleshooting and Keurig Elite troubleshooting. The needle must be kept clean because it punctures the lids of the coffee capsules inserted into your Keurig machine. You can do this by sticking a paper clip or pin in the tube where the Keurig needle punctures the capsule.  

The needle can be a tricky part to clean. To clean the needle thoroughly, you will also need to clean all of the internal filters of your machine. You can use a potent cleaning mix of hot water and vinegar to clean the internal filters thoroughly. Then you can wash them with soap and hot water. Finally, you should put water through the filters for several cycles to eliminate unwanted flavors.  

4. Clogged Water Reservoir 

A clogged water reservoir is due to a build-up of debris or used coffee grounds in the water reservoir. This build-up results from constant usage and not enough water reservoir cleaning. This won't be relevant if you’re doing Keurig K Mini troubleshooting as it lacks a reservoir. 

Simply remove the metal mesh and wash it with warm soap and water to clean the water reservoir. Then dry it with a paper towel before re-inserting it into the Keurig coffee maker. When you have re-inserted it, do a few brewing cycles with just water to test it and eliminate any soapy tastes. If it’s still not brewing, you will need to keep troubleshooting your Keurig.   

5. Electrical Fault 

If you had tried the above suggestions with no success, then the problem with your Keurig coffee maker could be electrical. A sign of this could be your Keurig's electrical display. For example, the display might be flashing, not displaying all the information correctly, or the touch screen might not work.  

The best way to fix this problem is to unplug your Keurig for a few minutes before plugging it back in. If this technique fixes it, then it was simply an electrical glitch. However, if the problem persists, it might be something to do with the mechanics rather than an electrical fault. In that case, consider the other Keurig coffee maker troubleshooting tips in this article.  

6. Not Brewing A Full Cup 

Another common problem with the Keurig coffee maker is that it doesn’t brew a full cup of coffee. Brewing a less than full cup could be due to several different reasons. If it's making any strange noises, you may have wondered, 'why is my Keurig clicking and not brewing?’. The leading cause of this is due to clogging of the waterline. Clogging of the waterline significantly reduces the amount of coffee produced. The clogging of water lines is primarily due to debris and excess coffee grounds. 

To fix this, simply go through the brewing cycle a few times with only water. Don’t insert the capsule. It would help if you also cleaned the needle and water reservoir. When you have cleared the waterline, you should start getting the right amount of coffee again. 

7. Not Turning On 

Your Keurig coffee machine not turning on can be one of the trickier problems to fix (especially if you’re craving a coffee first thing in the morning.) Usually, if your Keurig is plugged in and you hold down the power button, your Keurig should turn on, and you should receive a welcome greeting on the display screen.  

However, if it doesn’t, the Keurig power button not working could be the problem, and you’ll need to find out. Make sure that your device is plugged into a socket that is working. Try a different socket to ensure that it’s not a faulty socket. If this doesn’t work, you should call customer care.   

8. Shuts Off On Its Own 

Fewer things are more enraging than when you're craving a coffee, and in the middle of brewing, your machine decides to switch off. The first thing you can check is the water reservoir magnet. If it's out of place, your Keurig will automatically switch off.  

Secondly, you will need to ensure that no timers and automatic shut-off features are switched on. You can find which ones your Keurig coffee maker has by referring to the instruction manual or by watching some videos online. If the problem continues the next time you power up your Keurig machine, you should contact customer care. 

9. Won’t Dispense Water (Pump Issues) 

If no water is coming out of your Keurig, then the Keurig pump not working could be the reason. This is a complicated subject, so we'll look at it in brief. There are numerous issues that can affect the water pump on Keurig coffee makers. Scaling is one of them, and debris inside the machine is another.  

Discovering which problem you have starts with removing the reservoir and examining it. Then refill it to one-third capacity, shake it, and clean the opening where the water usually enters via the pump. If this doesn't solve the problem, you've likely got a blockage inside the machine or a different technical fault.

10. Keurig Leaking 

The most common reason for a Keurig machine to leak is simply overfilling the water reservoir. This is easily done when you're in a rush, and it's the first thing that you should check if this happens. If it's not overflowing, there is likely a blockage somewhere in the machine. You can resolve this by cleaning your Keurig coffee maker and ensuring anything that could block its operation is washed out.  

If neither of these solutions works, then its possible your Keurig has a loose or broken upper gasket. This will need tightening or replacing, and you’ll need to research where to buy the part and how to replace it. It could also be a valve or hose that’s disconnected within the machine. In this case, you’ll have to contact customer care. 

11. Touch Screen Won’t Work 

The Keurig touch screen not working is another issue that can occur. If your touch screen isn't working, you should use the same technique mentioned above that we used to find any electrical faults. Unplug your Keurig coffee maker for a couple of minutes and plug it back in. Then, switch it back on and see if your touch screen is working again.  

Another thing you can do is clean the touchscreen. Spray a little bit of window cleaner onto a soft cloth or paper towel. Make sure to clean around the edges and the crevices on the outer edge of the touch screen. Dirt and dust can often stop your touch screen from working correctly, so it’s essential to clean it regularly and keep it dust-free.   

12. All Lights On 

If most of the buttons such as the ‘Add Water,’ ‘Heat,’ and ‘Cup Size’ buttons are on or flashing, then there could be an issue with one of the parts of your Keurig coffee maker.  

The first part you should check is the water reservoir. You should remove it and check that it is clean before putting it back in place. Next, you should check the water valve for any blockages and remove them if there are any. You will also need to ensure that the tank is in place correctly on its holder. Fill it with water and make sure that it is connected correctly.  

Next, you should run a brewing cycle with water alone. Remove any coffee capsules and run the brewing cycle. Select 6oz or 8oz and measure the amount with a measuring cup. If it’s the correct amount and all lights return to normal, your Keurig coffee maker will be fixed.    

If it’s not the right amount, then remove the water filter and repeat the brewing cycle. If you now get the right amount, you’ll need to change your water filter.

Everything You Need To Know  

To fix a Keurig machine, you won't need to purchase any complex tools or supplies, but you should follow the health and safety precautions included in your Keurig instruction manual. If you’re unsure about anything, it’s wise to do more research, but it’s okay to attempt fixing your Keurig by yourself. In most cases, you’ll make progress.  

One of the most common ways to solve any problems with your Keurig is through descaling. To descale your Keurig coffee maker, you’ll need to add a descaling solution or a mixture of vinegar and soap, perform a cleansing brew, leave the Keurig for 30 minutes and then wash it. 

Knowing how to reset your Keurig machine is also useful when it won't brew. Older Keurig machines have to be turned off, drained, and left for a while. But for newer models, it's complicated, and you might wonder, 'where is the reset button on my Keurig?' It involves pressing a sequence of buttons that varies by model.  

If your Keurig coffee maker won’t brew, check through the problems listed in the sections above and see if any of them apply to you. If not, you may need to contact customer care.

Step-By-Step Troubleshooting Guide 

If your Keurig coffee maker isn’t working and you’re unsure why, then this troubleshooting guide should help you find the solution.  

  1. 1

    Another common mistake is not having your machine turned on. After you plug it in, don’t forget to press the power button.  
  9. 9
    Deep clean your Keurig often. The more you deep clean your Keurig, the longer it will stay working and keep brewing tasty coffee.
