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.
Solution
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 In Keurig K cafe
Some users try to froth milk while coffee is still brewing in Keurig K cafe. Keurig machines can’t handle these two processes at the same time. Therefore the light of the frother base starts pulsing.
