2) Don’t overfill the frother jug

The frother will not function properly when you add more milk than it can handle.


In this situation, make sure that the milk does not cross the overfill line. Add the milk in the second cycle if you want more instead of overfilling.

3) Clean the Whisk of Milk frother

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.


You must clean the frother after every use. Simply rinse the frother jug soak the whisk in warm soapy water and scrub the guck off with a light brush.

5) Don’t Try to brew coffee and froth milk at the same time In Keurig K cafe

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

If your Keurig 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.

It is recommended to use fresh dairy milk, especially 2 percent or whole milk. These kinds of milk have a high-fat content, making them suitable for frothing. Although, You can also use skimmed milk or non-dairy kinds of milk such as Almond or Soy Milk but it won’t form the perfect froth.

Also, it is strictly not recommended to add creamer to the frother as it can damage the frother. You can add the creamer at the top after preparing a cup of Cappucino or Latte
