Group gasket leaking
A worn group gasket. We back-flush, fit a fresh gasket, and check lock-up.
Built for the long shift
When a Classe 9 quits in the middle of a long shift, a high-volume bar loses its rhythm fast. We repair this multi-boiler Rancilio routinely: group temperature drifting across the heads, brew pressure sagging under load, a steam circuit gone weak, flow meters that have mineralized. Tell us what it's doing and the common wear parts are already on the van.

Rancilio · High-volume traditional espresso
The Classe 9 is Rancilio's high-volume chassis, a multi-boiler machine built for long, busy shifts. It runs as the semi-automatic S that specialty operators favour or the USB trim with volumetric dosing, and higher builds add per-group temperature control. High-volume cafes, multi-location operators, and hotel programs run it at hundreds of shots a day. On the bench the multi-boiler layout means more circuits to keep in balance, so group temperature, pressure, and flow-meter health are where the Classe 9 asks for attention.
Why Grajqevci
Call in the morning and a technician is usually on-site before the day is out. Most Rancilio Classe 9 jobs get diagnosed and fixed on the first visit.
Commercial coffee equipment is all we do, and Rancilio Classe 9 is part of the weekly rotation. Not a generalist guessing at a service manual. Genuine OEM parts, industry-standard procedures.
Flat rate for the visit, with parts billed separately. For bigger jobs you'll see a written quote on-site before we proceed.

Classe 9 faults we diagnose
These are the Classe 9 faults we see on real service calls, from group temperature drift to weak steam, each with its cause and the fix.
A worn group gasket. We back-flush, fit a fresh gasket, and check lock-up.
A clogged dispersion screen. We soak it in cafiza and replace it if worn.
Pump wear. We measure brew pressure, set the OPV to 9 bar, and replace the pump if it's below spec.
A clogged gicleur on one group. We pull it and clean it ultrasonically.
A chattering pressure stat. We replace it and confirm steady pressure.
A scaled boiler element. We descale and replace it if it's drawing low.
Group temperature variance across the boilers. We test the sensors against a reference probe and descale the affected circuit.
A scaled element. We descale the circuit and test resistance.
We pressure-test the circuits, dye-trace the chassis, and replace the weeping fitting.
A scaled level probe or a fill solenoid leaking past. We clean the probe and replace the solenoid.
A tired steam valve cartridge. We rebuild it with a fresh kit.
A scaled element. We descale it, test resistance, and replace it if it's drawing low.
A failed brew microswitch. We replace it.
A failed cup-warmer element. We test it and replace it.
A drip tray drain blocked with coffee fines. We clear the pathway.

The record
Their tech caught a worn pump on a scheduled maintenance visit before it actually failed. That's the difference between maintenance and just servicing what broke.

Updated July 2026
On the multi-boiler Classe 9 each group runs off its own circuit, so a drifted sensor or scale around one group shows up as temperature variance. We test the sensors against a reference probe, descale the affected circuit, and bring the groups back into line. Higher builds let us trim per-group offsets too.
It depends on volume. The Classe 9 is built for hundreds of shots a day and long shifts, so if you're pushing real throughput across two or three groups it's the right tool. For lighter volume the Classe 7 or 5 is a better economic fit, and we'll say so honestly.
Usually a worn pump that can't keep up under full load, or an OPV that's drifted. We measure pressure at the portafilter under load, reset the OPV, and replace the pump if it's below spec. We also check inlet pressure, since a starved supply mimics pump wear.
Specialty operators often prefer the semi-automatic S for manual control, while the USB trim gives volumetric dosing and repeatable shots across a long shift. Both are multi-boiler underneath. We service either, and the choice is about how your baristas like to work.
At high volume, plan on a descale and full seal check every few months, with group and steam circuits checked each time. A machine running near its 450-shot rating builds scale and wear fast, so a regular interval keeps it off the emergency list.
Yes. Mineralized flow meters are the usual cause. We pull and clean each meter, reprogram the doses by weight, and replace a meter that's worn past cleaning. After that the doses hold across the shift.
Yes, multi-machine visits are routine. One booking covers every group across your bars, with a report on each machine. When the same fault shows up on several, it usually points to the water or the cleaning routine rather than the machines.
Usually yes. A group rebuild costs a fraction of replacing a high-volume machine, and it brings extraction right back. We measure before and after and give you an honest read on the rest of the machine before you commit.
Flat rate for the visit, parts billed at their actual cost on top. You'll hear the rate when you book, and for bigger jobs we quote in writing on-site before any work starts. No estimate that balloons mid-job.
Same-day in most cases. Call in the morning and a technician is usually on-site before the day is out; calls placed later in the day book for the next morning. Urgent breakdowns get priority routing.
The GTA and most of the Golden Horseshoe: Toronto through Mississauga, Vaughan, and Markham, out to Oshawa, Hamilton, and Niagara. If you're not sure you're in range, call and we'll tell you straight.
No. We work call by call. Plenty of customers put us on a maintenance schedule eventually, but that's their choice after seeing the work, never a requirement.
Parts carry their manufacturer warranty, and we stand behind our labour: if the same fault recurs, call us and we'll review it. Specific terms are discussed upfront on each job, not promised in marketing copy.
On-site whenever possible, which is most of the time. If a job genuinely needs the bench, like a full boiler rebuild or major electronics work, we'll say so before anything leaves your building.
Call us or send the form on this page. We confirm the machine, the fault, and a time window the same day. If it's urgent, say so and we'll route the nearest technician.
Diagnosis first: we confirm the fault, tell you what caused it, and quote the fix before touching a wrench. Most repairs finish in that same visit because the common wear parts ride on the truck.
High-wear parts for the platforms we service constantly ride on the truck. Anything else we order, usually next-day where suppliers allow, and we tell you the lead time before committing you to anything.
Usually, yes. We service legacy machines for as long as parts can be sourced, and we're honest when a repair stops making financial sense against a replacement. You get the math, you make the call.
Often, but that's not the pitch. We quote against the actual work, not a factory pricing book, and we'll tell you when a manufacturer warranty claim is the better route. Transparency is the value; the price usually follows.
Yes, and we do it by default on the way out. Half of repeat faults trace back to skipped daily cleaning or wrong routine, so the technician walks your team through what actually matters before leaving.
One call, a real diagnosis, and a flat-rate quote before any work.
