This is a Zacconi Riviera Baby lever espresso machine made of brass and stainless steel with a chrome finish.
It operates as a piston machine at approximately 120°C.
This model is known for having a build quality often considered more robust than its competitor, the La Pavoni Europiccola.
This is a lovely machine which needs a service.
The boiler heats normally .
The pressure gauge reads ok
The steamer is fine.
There is a leak when you use leaver which I suspect would be fixed with a service kit for the rubber piston seals. These are readily available for about £50. Or a full service kit (best option for Approximately £70)
The lower price reflects the issue described
