The Rancilio Silvia is a Melbourne favourite, and Rancilio’s commercial Classe machines are common in cafes. Here’s what goes wrong most often.
1. Silvia leaking from the group
Why it happens: the group gasket hardens and stops sealing.
The fix: a new group gasket and shower screen. We also check the 3-way solenoid valve.
2. Steam wand dripping
Why it happens: worn steam valve seals.
The fix: rebuild the steam valve.
3. Not heating
Why it happens: a failed thermostat, a burnt-out element, or the boiler running dry.
The fix: we test the heating circuit, replace the failed part and make sure the boiler fills properly.
4. Low pressure or slow shots
Why it happens: scale in the boiler or solenoid, a worn pump or a blocked shower screen.
The fix: descale, service the solenoid valve and test the pump.
5. Commercial Classe faults
Why it happens: on Classe 5, 7 and 9 machines we often see autofill faults, flowmeter problems, group leaks and steam valve wear.
The fix: regular group servicing and filtered water prevent most of these.
