Breville's consumer espresso machines use thermocoil heating (Barista Express, Bambino Plus) or dual stainless boilers (Oracle, Oracle Touch). The thermocoil system heats on demand — faster startup but more scale-sensitive than a boiler. Most Breville failures trace to the group head gasket, thermocoil scale, OPV drift, or grinder obstruction. This hub covers all three machine lines.
