A Rancilio that will not heat or brew: separate the symptoms
Silvia and commercial Rancilio equipment need different checks. Describe heat, water delivery, and steam separately when booking.
Identify the Rancilio before testing
The Silvia is a home machine with a single boiler. That matters when describing a change between brewing and steaming. A commercial Rancilio or a different home model can have a different heating and water arrangement. Send the model label rather than describing every machine as a Silvia.
Write down three observations: whether the machine powers on, whether water comes from the group under normal operation, and whether it produces steam in the correct operating mode. You do not need to open anything to give us that starting point.
When heat is missing
A lit panel is not proof that a boiler is heating. We check the control request, temperature sensing, and heater circuit as appropriate to the model. A stopped heating cycle may have more than one cause; replacing a thermostat by guesswork can leave the original problem unresolved.
When the pump runs but coffee does not flow
Tell us whether the symptom occurs only with a prepared coffee basket or also during the manual’s normal flushing procedure. A coffee restriction and a machine water-path problem require different investigations. Stop a test if water is unavailable or the machine sounds abnormal. Do not keep running a pump in the hope that it will clear itself.
Bringing the evidence with the machine
Include a short recording made during ordinary use, if you already have one, plus any recent cleaning history. Do not run a leaking or electrically unsafe unit to obtain a video. At the bench we investigate the reported fault and explain the proposed repair before work proceeds. Home and commercial deposits differ; the model determines the booking terms.
Model reference
Rancilio’s Silvia product information describes the single-boiler home platform. It should not be used as a wiring or repair guide for a commercial machine.
Pickup, assessment, and return
Rancilio home deposit: $200. Commercial deposit: $200 to $450, selected by model. Additional bench work: $150 an hour.
The deposit pays for collection, bench diagnosis, and delivery back to you. It is not a credit against the repair charge. We seek your approval for the proposed repair.
Allow up to a week for diagnosis. Most repair jobs run 3–4 weeks; confirm the status of your own machine with us.
Repair coverage: parts 6 months; labor 6 months; consumables 90 days. A return of the same repaired fault is corrected without another charge.

Before you book
Does weak coffee prove the pump needs replacing?
No. The coffee preparation and the water circuit both need consideration before a pump diagnosis.
