Group head gasket weeping
Routine consumable wear. We replace the gasket and dispersion screen, clean the group threads, and reseat the portafilter under brew pressure to confirm a dry seal.

Chrome on the bar, restored
Sabrina sitting cold and gorgeous, doing nobody any good? We repair the heritage-shelled Astoria behind that chrome: a weeping group gasket, a steam valve dripping when it's closed, pump pressure off 9 bars, a boiler slow to recover. We handle the panels with care and put the showpiece back to work, usually in one visit.

Astoria · Current heritage-styled traditional espresso
The Sabrina is Astoria's heritage-styled café machine: 1960s chrome and curves over current CMA hydraulics. It pulls up to 250 shots a group on a heat-exchanger boiler, and specialty bars run it as much for presence as performance. Under the styling the service story is ordinary traditional-espresso work: group seals, steam valves, pump pressure, and boiler scale, with extra care on teardown so the panels and chrome come off and back on clean.
Why Grajqevci
Call in the morning and a technician is usually on-site before the day is out. Most Astoria Sabrina jobs get diagnosed and fixed on the first visit.
Commercial coffee equipment is all we do, and Astoria Sabrina is one of the platforms we know best. 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.

Sabrina faults we diagnose
The Sabrina faults below are the ones we see most, group seals, steam valves, pump pressure, and boiler recovery, with the cause and the fix for each, and notes on handling the chrome.
Routine consumable wear. We replace the gasket and dispersion screen, clean the group threads, and reseat the portafilter under brew pressure to confirm a dry seal.
Oil baking onto the screen disturbs even flow. We replace the screen, backflush with detergent, and verify even dispersion before reassembly.
Scale on the solenoid seat or coil wear. We test the coil, descale the valve, and rebuild the cartridge so the group fills and drains cleanly.
Mechanical pressurestat wear. We test against a reference gauge, adjust the deadband, and replace it if it's out of tolerance.
Pump wear, OPV drift, or an inlet-screen clog. We gauge brew pressure, isolate the cause, adjust the OPV, and quote a pump head if it's below spec.
Air, a starved inlet, or a worn vane. We bleed the line, confirm inlet pressure, and inspect the pump.
HX scale, steam-boiler pressure drift, or sensor calibration. We descale the HX, verify pressurestat calibration, and confirm brew water at the group with a Scace device.
Scale or a drifting pressurestat. We descale, measure element resistance, verify the pressurestat, and replace the failing part.
A group seal, a cracked line, or a drain blockage. We pressure-test, clear the drain, and trace the leak.
A failed solenoid, a scaled valve seat, or a level probe scaled over. We test the solenoid, descale the valve, and replace the probe if needed.
Steam valve cartridge wear. We rebuild the valve, descale the wand internals, and verify a dry shut-off.
Boiler not at pressure, or scale in the circuit. We descale, verify pressure under load, and clear the tip jets.
Flow-meter mineral buildup or a worn membrane. We clean the flow meter, verify pulse output, reprogram doses, and replace the membrane if it's intermittent.
We read the fault history, identify the code, and address the root cause. Most faults resolve with a sensor or relay replacement.
Sabrina body panels need careful handling on teardown. We protect surfaces during service, retorque mounting hardware to spec, and document any cosmetic state before and after the visit.

Not if it's done carefully, which is the point of using a specialist. The Sabrina's body panels and chrome need protection during teardown, so we cover surfaces, retorque mounting hardware to spec, and document the cosmetic state before and after the visit.
The steam valve cartridge or seat O-ring has worn, letting condensate and pressurized water past. We rebuild the valve with a fresh cartridge and seat O-rings, descale the wand internals if scale is contributing, and verify a fully dry shut-off across several steam cycles.
Almost always a worn group gasket. We replace the gasket and dispersion screen as a pair, clean the group threads, and reseat the portafilter so it seals clean under brew pressure. It's quick, routine work.
On the Sabrina's heat-exchanger boiler, brew temperature tracks steam-boiler pressure and HX scale. We descale the heat exchanger, check pressurestat calibration, and confirm brew water at the group with a Scace device so shots come back to a stable temperature.
Largely, yes. Behind the heritage shell the Sabrina runs current CMA hydraulics, so group seals, steam valves, pressurestats, and pump parts come from the same well-stocked catalogue as the rest of the range. The aesthetic is unique; the service parts mostly aren't.
Usually a scaled level probe reading wrong, a failed inlet solenoid, or scale in the valve seat. We test the solenoid electrically, descale the valve, clean or replace the level probe, and verify the auto-fill cycle runs end to end.
On a copper-boiler heat-exchanger platform, twelve to fifteen years of daily service is realistic with the scale kept down and the seals refreshed on schedule. The heritage styling doesn't change the lifespan; the water and the upkeep do.
Yes. The SAEP adds a mechanical pre-infusion chamber to the same Sabrina platform, which is one more wear point in the brew path. We strip and reseal the chamber, verify the check-valve, and confirm the pressure ramp on a gauge, on top of the usual Sabrina service.
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. 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, careful hands on the chrome, and the machine back to work.
