Leaks on your Nespresso Aguila machine can be caused by a number of reasons. 

• Are all the milk tubes connected properly? Please tighten the connectors in order to prevent leaks. 
• Are the tubes free from wear and tear? Hardening of the milk tubes or cracks can cause leaks. Please check and replace with new tubes if needed.
• Is there a blockage in the milk system? If so, please run a full cleaning cycle:

1. Empty the capsule drawer.
2. Press the cleaning button.
   • To start the cleaning, press the cleaning button again and hold it for 3 seconds. 
   • To exit the cleaning, press any other button. 
3. Carefully remove and drain the milk container(s).
4. Carefully wipe both milk suction tubes using different single-use disposable tissues or paper towels. Afterwards, press any button. 
5. Clean the milk container(s) in a dishwasher and place aside. 
6. Place empty 5 litre container into the refrigerator and guide both suction tubes into the container. The refrigerator door must be open during the cleaning process.
7. Press any button. 
8. Remove the cleaning key and insert two cleaning tablets. 
9. Insert the cleaning key. The cleaning procedure will starts automatically. 
   • After the cleaning process, the machine switches to the maximum saving mode. 
10. After the cleaning, carefully wipe both milk suction tubes using different single-use disposable tissues or paper towels. The use of non-disposable tissue or sponge can lead to bacterial contamination of the milk. Thoroughly clean the inside walls of the fridge with potable water. 
11. Empty the remaining water and clean the 5 litre container in dishwasher. 
12. Place the empty milk container(s) back into the refrigerator.
