Another reason could be that the milk being used is not fresh or has expired, which can affect its ability to froth properly. Additionally, if the Aeroccino 3 is not properly cleaned and maintained, it may stop frothing as well. Regular cleaning and maintenance of the Aeroccino 3 can help ensure consistent frothing performance. **

Additionally, avoid leaving milk in the container for extended periods of time to prevent spoilage. **
