The unit has a 4yr warranty call the 800# and the company will send you a new unit. 1 reason why it leaks is if you leave food inside the unit the food acids will eat thru the metal n over time it creats small holes hence the leak. make sure that you run water thru the unit and no food is left inside. units with date code 2005 have the latest updates for this issue. Yeas I have the 444 unit. powerfull, quite and has small leaks.
