Not so long ago when I was trying to make coffee, my mukka leaked water at the point where the upper part and the heater unit join. That was quite frustrating because the water would leak and I had to clean up this mess! I thought my mukka was unussable at the time but that was not the case! A very nice lady from Bialetti support center helped me out: she suggested that i put some machine oil on where it screw and then I sould screw it and unscrew it four to five times. It actually worked! The oil helped to remove tiny bits of coffee that were concentrated there and cause the leaking. After that simple prcedure the leaking stopped and I could enjoy my coffee again!
