5332149100 Espresso Machine Generator O-Ring, Genuine Delonghi
If your Delonghi bean-to-cup espresso machine has started leaking water during brewing, or pressure seems weaker than usual, a worn generator O-ring is a common cause. This genuine O-ring, part number 5332149100, seals the generator (the boiler unit that produces brewing pressure) to keep water and pressure exactly where they should be.

What This Part Does
This O-ring forms a seal at the generator, the part of the machine that heats water and builds the pressure needed to brew espresso. As the ring ages, the silicone hardens and flattens under repeated heat and pressure cycles, which can let water or steam escape past the joint instead of being forced through the coffee.
Common Fault Symptoms
- Water leaking from underneath or around the machine during brewing
- Noticeably weaker brewing pressure than usual
- Espresso extraction that tastes weak or inconsistent
- Steam or water escaping from around the generator housing
