Possible cause:
The hot water spout is not inserted or is inserted incorrectly.
When the hot water spout is inserted correctly, the machine does a "beep" sound. If this does not occur, please get in contact with our Customer Support.
Please Note:
To properly hear the "beep" sound, the "BEEP" function needs to be ON. Follow this Step-by-Step Guide to check if the function is ON.
