Saeco Espresso Machine Group Head Gasket Group head gasket for Saeco's home espresso lineup, sealing the portafilter against the group head to prevent water bypass and channeling around the basket rim. SPECIFICATIONS 66 x 36 x 16 mm COMPATIBILITY Fits: Saeco Armonia, Aroma (not the commercial Aroma SE), Classico, Estro Vapore (Starbucks Barista), Espresso Dream, Gran Crema, Magic Cappuccino, Poemia, Rio Profi, Rio Vapore (Starbucks Barista), and Via Venezia Replaces: Saeco/Gaggia #145841500; also cross-references to Ascaso, REPA, and Pavoni part numbers of the same spec INSTALLATION Simple DIY replacement, the old gasket pries out and the new one presses into the group head groove. PRO TIPS If you're seeing grounds spray around the portafilter rim or a sudden drop in brew pressure, a hardened or flattened group gasket is the most common cause, a five-minute fix that's often mistaken for a pump or valve problem. Double check that your Aroma is the home model, not the commercial Aroma SE, the two use different gaskets despite the similar name.
