At the end of this small routine is a screw that closes the backflush channel, sealed by a tiny O-Ring.\u003c\/p\u003e\n\u003cp\u003eOn the LEVA and on machines with Smart Steam, this O-Ring sits in the same spot: small, unassuming, but responsible for making sure no pressure escapes sideways during backflushing.\u003c\/p\u003e\n\u003ch3\u003eA seal that works quietly – until it doesn't\u003c\/h3\u003e\n\u003cp\u003eRubber seals lose elasticity over time, mainly through repeated heat and pressure. Once an O-Ring turns brittle, it no longer seals completely – an effect that doesn't show up right away but becomes more noticeable with every backflush. Since the backflush screw is moved regularly during daily care, this O-Ring is one of the parts most likely to need replacing.\u003c\/p\u003e\n\u003cp\u003eThe replacement is small but important for a system that depends on a tight seal: the daily backflushing routine without cleaning agent, and the more thorough cleaning roughly every 50 shots.\u003c\/p\u003e\n\u003ch3\u003eAt a glance\u003c\/h3\u003e\n\u003ctable class=\"ccc-compare-table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible with\u003c\/td\u003e\n\u003ctd\u003eLa Marzocco LEVA and machines with Smart Steam (backflush screw)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eO-Ring seal for the backflush screw\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eRubber, heat-resistant\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eLa Marzocco, Florence, Italy\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eItem number\u003c\/td\u003e\n\u003ctd\u003eA02345\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eWho it's for\u003c\/h3\u003e\n\u003cp\u003eFor anyone with a LEVA or a machine with Smart Steam whose backflush screw no longer seals completely.
