Make sure the milk hose is securely connected to both the adjustable outlet and milk container. Check that the internal milk intake tube is correctly fitted to the container lid.

Milk residue can restrict the milk unit. Remove the detachable milk unit from the outlet, rinse its components with warm water and clean them using the supplied brush, following Melitta's instructions.

After preparing milk drinks, run the Easy Cleaning programme to flush the milk system with hot water and steam. This helps prevent milk residue building up inside the hose and outlet.

Hold menu/ok for two seconds, then select Care → Cleaning milk system. Follow the display instructions using the manufacturer-recommended milk system cleaner.

Melitta recommends testing the milk hose directly in a milk carton or cup, with the black end cap removed. This can help identify whether the milk container connection is restricting milk intake.

If milk frothing remains weak after cleaning, Melitta recommends running the machine's descaling programme. Follow the on-screen instructions and use a suitable descaling product.
