5332149100 Genuine O-Ring for De'Longhi Coffee Machines, DeLonghi Rubber O-Ring Seal for Leaks and Drips

Genuine De'Longhi O-ring, part number 5332149100. O-rings like this seal the joints between water tanks, pipes, valves and the brew unit in De'Longhi coffee machines, and they harden or flatten with heat and age. We don't hold a model list for 5332149100, and the size isn't on file, so check the number against the exploded parts diagram for your machine, or send us your model number.

Leaks and drips from a worn O-ring

Inside a coffee machine, O-rings stop hot water and steam escaping where two parts meet. Repeated heating, scale and old coffee oils make the rubber harden, crack or lose its shape. Once that happens you might notice water pooling under the machine, drips around the brew unit or water tank, weak pressure, or steam hissing from a joint. Swapping a perished O-ring is a small, simple fix, but it has to be the right size and material for the job, which is why the part number matters.

Changing an O-ring

Unplug the machine and let it cool fully before opening it up. Remove the old O-ring with a plastic pick so you don't scratch the groove, then wipe the groove clean. A light smear of food safe silicone grease helps the new ring seat without twisting. Reassemble, refill the tank and check for drips with the first few cups.
