5313217701 Genuine O-Ring Gasket for De'Longhi Coffee Machines, DeLonghi Replacement Seal

Here is the genuine De'Longhi O-ring gasket with part number 5313217701, a factory seal for De'Longhi coffee machines. Small rubber seals like this sit at the joints where water and steam pass between parts, and they harden and flatten with heat over time. The size and exact position aren't recorded on our system, so match 5313217701 against the exploded view for your machine or the number on your old parts before you buy.

Leaks and pressure loss from a worn coffee machine seal

Every connection inside an espresso or bean to cup machine depends on a seal to stay watertight under pump pressure and heat. When an O-ring perishes, water starts to weep from the joint. You might see puddles under the machine, a drip tray that fills faster than it should, hissing or spitting from a fitting, or coffee that runs thin because pressure is escaping. Scale and coffee oils speed up the wear, so seals in a well used machine often go at the same time as other service items.

Tips for replacing an O-ring

Unplug the machine and let it cool fully, as boilers and thermoblocks stay hot for a while. Lift the old O-ring out with a plastic pick rather than a metal screwdriver, which can scratch the groove and cause a new leak. Wipe the groove clean, then add a light smear of food-safe silicone grease to the new seal before you push the parts back together.

Questions about this part

How do I find my De'Longhi model number?
