What should I do if the cappuccino system is not pulling in milk or producing little froth?

Check that the appliance is correctly assembled, the lid button is in the CAPPUCCINO position, and that the steam nozzle is not blocked. Ensure the air nozzle is in place and not blocked — if it is, soak it in hot water with dish detergent, then rinse — and verify the flexible pipe is not blocked, twisted, or improperly inserted into the cassette. Also ensure the milk suction pipe is fully immersed in the milk, and use very fresh, cold pasteurized or UHT milk recently opened for best results. (Page 14)
