Common Questions
Can a worn O-ring cause steam or water leak from the frother tip?
Yes. A worn, flattened, cracked, or hardened O-ring can prevent a proper seal and may cause steam or water leaking from the frother tip.
Should I replace this O-ring during repair?
Yes. Replace it if it is damaged, flattened, brittle, or no longer seals correctly. Because seals are wear items, we also generally recommend replacement every 4 years during routine servicing, even if damage is not obvious. Reusing an old seal can cause leaks after reassembly.
Will this fit my machine?
Use the compatibility checker and the relevant exploded diagrams to confirm your machine model and the exact fitting location.
Is this a genuine part?
No. This is a compatible replacement and is not a genuine Gaggia part.
