Keurig K cafe Milk Frother not working Properly | 7 reasons and solutions

Usually, there are many reasons behind Keurig K-cafe frother not working, especially if you haven’t been keeping it clean. Here we discuss some of the likely reasons why the Keurig K-café coffee machine isn’t frothing

1) The frother does not fit properly on the frother base

Sometimes the frother isn’t properly placed on the machine base. Usually, this happens after you have moved or cleaned your machine. The frother isn’t functioning, and the light will continuously blink until you have correctly placed the frother on the machine base.


Make sure that the frother is correctly seated on the machine base.

2) Milk is above the maximum line.

The frother will not function properly when you add more milk than it can handle. In some scenarios, you overfill milk in the machine so it does not work properly.


In this situation, make sure that the milk does not cross the overfill line. Add the milk in the second cycle if needed.

3)Trying to brew coffee and froth milk at the same time.

Some users try to froth milk while coffee is still brewing. These two processes conceding together make it much more difficult for the Keurig machine to handle. Therefore the light of the frother base starts pulsing.


Wait patiently until the machine brew coffee. Once the coffee is brewed, the frother will automatically start frothing milk.

4)You haven’t covered the frother with the lid.

The frother will operate only when it covers with a lid. Sometimes users forget to cover the frother, which is why the milk frother isn’t working.


Make sure to cover the frother with the lid that is shipped with the brewer.

5)The whisk has a buildup guck.

If you haven’t cleaned your frother for a longer time, Guck will form around the whisk and other components of the frother. Guck inhibits the magnetic force used by the frother to prepare the milk.


The milk frother and the whisk are completely dishwasher-safe. Therefore, you may clean them anytime or after regular use. Soak the whisk in warm soapy water and scrub the guck off with a light brush when washing by hand.

After cleaning or moving the machine, many users forget to check whether the whisk is correctly positioned in the frother or not. The light of the frother starts blinking in that case


Make sure the magnetic whisk is securely attached to the frother.

7) Problem with the Milk

Because of the ingredients, milk from different companies has distinctive qualities. Some brands, for example, have different amounts of protein and fat.

If the frother is only heating the milk and not making the foam then it’s evident that there is issue with the milk.


If you have an issue with the quality of frothing, the only solution is to switch to another brand of milk. And also cold Milk froths better than warm milk.

Why is Keurig Frother only heating the milk but not frothing it?

If your Keurig K cafe frother is only heating the milk but not frothing it then there is an issue with the milk you are using. Your frother is completely fine.

Fresh dairy milk, especially 2 percent or whole milk, is usually preferable. This dairy milk has a high-fat content which makes them ideal for frothing. Although 1 percent milk might also work, using skimmed milk or creamer is not recommended.

Most people face this issue because they add the creamer to the frother while it is certainly not recommended and can damage the frother. You can add the creamer at the top after preparing a cup of Cappucino or Latte
