Adjust the coffee strength by selecting the coffee strength button on the control panel, which allows you to choose between different levels such as mild, medium, or strong.
Ensure the milk frother is clean and free of blockages. Check the steam nozzle for any milk residue and clean it with a damp cloth. Make sure the steam function is fully operational.
