How to Fix Your Keurig Not Brewing Full Cup

Person Fixing Keurig

Keurig is a great machine, but it’s not perfect. Sometimes your Keurig will just stop brewing a full cup of coffee or tea. It may be that the filter has gotten clogged up and needs to be cleaned out or replaced. Or maybe there’s something wrong with how your Keurig works or operates; there are many possible reasons why this could happen.


In a professional tone

Make sure that the water reservoir is filled with water.

  • Make sure that the water reservoir is filled with water.
  • Check the water level to ensure it is full. If your Keurig has a fill line, check that it’s not empty and that there’s enough room for more coffee in your cup. Also make sure there are no bubbles on top of your cup or anything else floating around inside of it—these could cause clogs as well!
  • Clean out any lingering crud from inside of the machine (and keep an eye out for mice while you’re at it). This will help prevent any future issues down the road, so take advantage of this opportunity!

The pod may be to blame.

  • Make sure the pod is inserted correctly. If it’s not, or if you have multiple pods in your machine, then this may be the cause of your problem.
  • Make sure the pod isn’t broken or damaged. If it’s still intact but just doesn’t seem to work, then this could be why your Keurig isn’t brewing full cups anymore!
  • Lastly, check expiration dates on all of your K-Cups and make sure they’re not expired—if they are, throw them away immediately!

The same pod may not work as well more than once.

  • If your keurig is not brewing full cups, there might be a problem with the pod.
  • To tell if the pod is bad: try brewing a new one. If it’s working correctly, then you know the issue was with your old one and not the machine itself.
  • If you are using an older model of Keurig coffee maker, then make sure that you check on how long ago it was manufactured by looking at its serial number (S/N). This can help identify any possible issues with either durability or functionality related to aging over time (e.g., lower water soluble solids content).

The Kcup needle may be clogged.

You may be able to fix the issue yourself. The Kcup needle may be clogged and if you clean it carefully, you’ll be able to unclog it without having to replace it.

  • Cleaning a Keurig Coffee Maker Needle

To avoid getting frustrated and wasting money on more expensive parts, try cleaning your coffee maker’s needle yourself first. First, make sure that you have some paper towels handy because once this process begins, there will likely be some residue left over from whatever was inside of it before (i.e., ground coffee). If so:

  • Pull off any paper sleeves from around your k-cup holder (if applicable).
  • Take out all of the old k-cups from inside of their holder as well as any filters or grounds still attached to them.*

Clean your needles.

If you’re having trouble brewing your favorite cup of coffee, it might be time to clean the needles. The Keurig brewer has been a staple in homes for decades and is still one of the most popular models on the market today. But if you’re experiencing issues with your machine, there could be a number of reasons why it’s not working properly:

  • Dirty or clogged needles – The main thing to keep in mind when cleaning these parts is that they should always be dry before using them again! You can use rubbing alcohol or even hydrogen peroxide if necessary; just make sure they’re completely dry before putting them away again (and don’t forget about any other parts). If they still aren’t functioning properly after this step, consider replacing them entirely—you might have other issues going on besides just being dirty!

Clean the inside of your machine regularly.

Keurig machines are easy to clean, but you should still take care of them. You can use a damp rag and warm water to scrub the inside of your machine, which will remove any residue buildup or coffee grounds that might be stuck in there.

This process is important because it helps prevent coffee grounds from clogging up your machine’s heating elements and slowing down its brewing time. The best way to tell if it’s time for cleaning: look at how much coffee brewed into each cup when you press the button on your brewer; if there isn’t enough left over after brewing one cup (and no more than half), then it may be time for some light scrubbing! Be careful not to get any water into any moving parts unless instructed by an expert technician—and remember: never use abrasive cleaners such as steel wool around delicate electronics like this one!

These tips will help you get back on track with your Keurig

  • Keep your Keurig clean.
  • Try different kcups in your machine. You can also try using different brands of kcups to see if that makes a difference for you, but make sure that you’re using the same brand and type of water (i.e., distilled or filtered).
  • Try different temperatures of water when brewing: cold and hot are both good options if you want something more flavorful or less bitter-tasting than what comes out at default settings on most machines out there today; however, if you’re looking for something similar again but not quite as intense then try putting it over ice instead! If this sounds like too much work then just stick with what works best for now until we find something else later down the road…or maybe even never because nobody likes change anyways so why bother trying anything new? Just kidding – I’m still working on getting mine fixed though so hopefully soon my life will go back into order again after all these years being stuck behind one person’s stupidity.”


Hopefully, you can now get your Keurig back on track. If you don’t want to fix the problem yourself, it might be worth calling in an expert. We know from experience how difficult it is to fix a broken Keurig, but with a little bit of care and attention we can help! In the meantime though, there are plenty of other things that could be causing your machine problems (such as clogged needles) so keep an eye out for those too.
