Lelit Bianca – Brand New with a Leak Issue

Here at 1st-line, we bench every single machine we ship. Prior to Breville purchasing Lelit in 2022, the entire Lelit line of espresso machines was the exception. In 2024, we had to start testing the entire Lelit line. Yesterday, we had a Lelit Bianca leaking from the manual grouphead valve. We took off the lower valve only to find build up on a brand new machine. The build up was not allowing a proper seal, and thus, when the group head lever was lifted, water leaked from the lower manual valve on the group head. In addition, the actual seal was imprinted.

Question is why is there build up on a brand new machine built in 2024? Why is the black gasket with an imprint?
