There’s a small leak in the connector. Ideas on how to fix this? Can’t get the part because it ain’t available in my country. The connector is the part no. 75 in the schematic diagram. Delonghi Dedica 685.
You probably need to replace the silicon o-rings in the thinner tube, pull the clip up and pull the tube, you’ll see the very small orings, my MrCoffee has the same issue, but I’m not able to find the replacement part. I coud make mine to stop leaking twice by just unmounting and mounting the orings in reverse order, i think they become molded after some time and lose the sealing.
