Weak or No Coffee Extraction

Solutions:

  • Ensure Proper Frother Setup: Make sure the frother is securely attached to the coffee maker and that the milk container is correctly positioned.

    2. Wash it thoroughly with warm, soapy water.

    4. Dry the frother completely before reattaching it to the machine.
