Once the gasket no longer sits exactly on the blind filter basket, pressure can escape sideways during backflushing instead of working fully through the group head – cleaning becomes less thorough without you noticing right away.\u003c\/p\u003e\n\u003cp\u003eReplacing this small ring is one of the simplest and most affordable maintenance jobs on the KB90, with a direct effect on your daily backflushing routine.\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 blind filter basket for KB90 (Straight-In)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eGasket for the blind filter basket\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\u003eA03149\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 KB90 whose blind filter basket no longer seals completely during backflushing, even though the basket itself is still in good condition.
