Keurig Frother Not Working: Here’s How To Fix It

Keurig is at the forefront of innovations when it comes to coffee devices. From single serve coffee makers to smart brewers, you can expect this company to deliver what you need. They even offer a standalone milk frother to accompany your coffee machine. However, like many brands, these kitchen appliances will inevitably experience issues at some point of usage.  

If you’re wondering why your Keurig frother is not working, you’ve come to the right place. We will discuss below the common causes and how to fix them.  

1. Flashing Light On The Front 

If this is happening to your Keurig frother, don’t panic. This may seem like a serious warning, but it’s just a sign that you are trying to froth milk while you are brewing a coffee. Unfortunately, you can’t do both at the same time.  

All you have to do is wait for the brew cycle to finish before you froth your milk. Once the brew is over, try to froth your milk, and you'll see that there's no issue with your device at all.  

2. Misaligned Frothing Wand 

Another reason you can’t froth milk with your Keurig device is its wand is poorly aligned. To check whether this may be the cause, you need to perform a steam test. This test can also eliminate the possibility that a more serious problem could cause your frother to malfunction.  

To do this, use a cup of water instead of milk to test the steam. Inspect the wand and check for any dirt or misalignment if you think there’s a problem with the steam function. Then, clean the frother if you find any dirt and try to use the steam again.  

If it still fails, adjust the wand. You can also check the user manual to ensure that you’re adjusting it correctly and prevent similar issues from happening in the future.  

3. Frother Not Covered With It's Lid 

Before you froth your milk, make sure that the device is covered with its lid. Sometimes, users forget to put on the top covering, which stops the device from functioning correctly. That’s why before you look for other causes, check whether you have covered it with the lid. If not, try putting it on and see if your Keurig Frother works.  

4. Milk Is Above The Max Line 

The max line in the Keurig Frother is there for a reason: to not overfill it with milk. If you’re putting so much milk into it than what’s shown, it might be the reason your machine isn’t working. Check the max line and make sure that your liquid is not more than that. Then, try using the frother again and see if your issue is fixed.  

5. Whisk Not Sat Properly  

If the components in your Keurig Frother are not properly placed, it’s most likely the reason it’s not frothing your milk. Another good practice before assuming that your device is broken is to check if all the moving parts are placed where they should be. If one of them is loose, such as the whisk, fix the position and use the machine again.  

6. Frother Not Sat Properly On The Base 

Again, the components of your Keurig Frother must be properly placed. If the frother is not sitting correctly on the base, it won't turn on or function even if there's no physical damage. Be sure always to check if it sits right where it should. Otherwise, you might end up spending time figuring out what’s wrong only to find out it was your mishandling all along.  

7. Build-Up Of Gunk Due To Poor Cleaning 

Like any kitchen appliance, you must know how to properly maintain your Keurig frother. If there’s a build-up of gunk in your device, it’s most likely to malfunction. So whenever you use your frother, clean it properly and ensure that you're not leaving any dirt that may lead to build up.  

8. Problem With The Type Of Milk You Are Trying To Froth 

Unfortunately, you can’t just froth any milk you have. You need to have the right quality of milk to make it work in your Keurig Frother. You need to make sure it’s not too warm or not too cold, or else it won’t create the consistency you want to achieve.  

Another thing that you should check is to make sure you’re using the correct milk. Sometimes, if you’re using something apart from skim milk, you won’t get the froth you usually see in cafes.  

9. Jug Stops Working Right After Starting The Frother 

If you just used the frother, the jug temperature might be a little high. This could cause the device to stop working. Before using it again, make sure that the jug’s temperature is cooled by letting it sit for at least two minutes or rinsing the inside of the jug with cold water. Once the jug is back to its normal temperature, try using it again.  

10. Frother’s Jug Is Overflowing 

In some cases, your frother works, but the jug produces so much froth that it overflows. If this is the case, you're probably using your froth wrong. When using the whisk with a round ring around it, you only need to fill the jug until the bottom line. A common mistake is pouring milk above the line, which results in overflow.  

11. Frother Motor Does Not Work 

Whenever you use the frother, you should clean it thoroughly. If you don’t, the milk residue will build up on the base and around the whisk. The machine won’t start if it detects the residue. So, remove the whisk and clean it along with the jug, using warm water with soap and a non-abrasive sponge.  

However, if you always clean your frother, the problem might be from the whisk attachment. Check if the black magnetic whisk is inserted and if it is, press it down firmly before you add milk.  

12. Frother Is Producing Charred Milk 

If your Keurig Frother is working but not producing the milk you want, you might be using it wrong. The good news is the device is functioning properly, and you don't have to worry about replacing it. However, you're frothing incorrectly, which produces unusable froth. All you have to do is follow the recommended milk dosage depending on the whisk you’ll use.  

If you use the whisk with the round ring around it, only fill the milk to the bottom line. If you want to steam milk using a smaller whisk, you can fill it to the top or bottom of the max line. Never try to use the frother below the max line, or you might run into some problems as well.  

Furthermore, not regularly cleaning the machine can cause the issue. If you don’t wash the jug and whisk after every use, there could be a milk residue in it, which can prevent the jug from sensing the temperature. Just clean the jug and whisk, and check if you're still getting charred milk.  

Keurig Frother Not Working: Here’s How To Fix It

How To Fix Keurig Frother Not Working? (Step-By-Step Guide) 

  • 1
    Before you froth your milk, make sure that you put the lid that is shipped with it on top.  
  • 2
    For better froth, always use chilled milk rather than warm milk. This is because cold milk froths much better than hot or room temperature milk. If you don’t have chilled milk, you can chill the frother cup before using it and dry the external walls before placing it on the base.  
  • 3
    Next, check the level of the milk in the frother and ensure that it’s not beyond the max line. If it is, pour some of it.  
  • 4
    Don’t brew your coffee and froth your milk at the same time. The device can only do one process at a time, so wait for the other one to complete before doing the next.  
  • 5
    Try to froth different kinds of milk and see which one can achieve the consistency you're looking for. Also, try different brands, as most companies have different formulations with their milk. Some have more proteins, while others have more fats. These types froth differently. At the same time, this will also allow you to see which varieties don't froth, so you can avoid purchasing them.  
  • 6
    When you brew your coffee before frothing your milk, make sure your brew selection is the Shot option for cappuccino or latte. According to some users, the frother attachment rarely works when they don’t press the “Shot Brew” before brewing the coffee.  
  • 7
    Check whether the magnetic whisk is correctly attached to the frother. If the milk is already poured into the jug, remove it so you can inspect it.  
  • 8
    Examine the frother and ensure that the cup is seated on the base correctly. Then, gently push it to keep it in place.  
  • 9
    Make it a habit to clean the frother, its lid, and whisk after every use. Not cleaning it right away can lead to different issues. Thankfully, the K-Cafe frother whisk and lid are all dishwasher-safe, making it easy to clean them right away. However, if you don’t own a dishwasher, you can soak the whisk in warm water with soap and scrub the dirt off with a soft brush. You should hand-wash the lid and frother using a soft lint-free cloth and rinse all parts thoroughly.
