Saturated groups, kept pulling
Storm SAE dead between rushes and a specialty queue building? We repair these saturated-group machines week in and week out: head seals weeping at the brew chamber, twin-PID temperature drifting between groups, SAE doses wandering, a touchscreen or controller locking up. Give us the symptom when you book and the parts for the likely fix ride along.

Astoria · Premium traditional espresso
The Storm SAE is CMA's modern flagship traditional machine, built for up to 350 shots a group. It runs saturated brew groups, a PID per group, and SAE electronic dosing on the same platform that carries the championship Tempesta, which is why specialty cafés and high-volume hospitality choose it. On the bench it's a known quantity: the saturated head seals wear first, the per-group PIDs need the odd recalibration, and the rest is honest mechanical work.
Why Grajqevci
Call in the morning and a technician is usually on-site before the day is out. Most Astoria Storm SAE jobs get diagnosed and fixed on the first visit.
Commercial coffee equipment is all we do, and Astoria Storm SAE 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.

Storm SAE faults we diagnose
These are the Storm SAE faults we meet on real service calls, from saturated-group seals to twin-PID drift, each with its cause and how we clear it.
On the Storm's saturated groups the head seal sits directly against the brew chamber, so it shows wear sooner than a conventional gasket. We pull the group, replace the head seal and dispersion screen as a pair, inspect the saturated-group body for pitting, and pressure-test the seal under brew load.
Routine consumable wear after nine to eighteen months on a busy bar. We swap the gasket and dispersion screen together, clean the group threads, and reseat the portafilter to confirm a dry seal under brew pressure.
Usually a pitted or oil-baked dispersion screen, or a worn brew-side seal letting water bypass the screen. We replace the screen, backflush with detergent, and inspect the screen carrier for warpage, verifying even flow across the face before reassembly.
Mechanical pressurestat wear opens up the differential over time, so steam pressure swings beyond spec. We test the pressurestat against a reference gauge, adjust the deadband where it's adjustable, and replace the unit if the swing is out of tolerance.
Rotary pump wear, OPV drift, or a clogged inlet screen are the three usual causes. We gauge brew pressure with a blind portafilter, isolate the pump from the OPV, adjust the valve against a calibrated gauge, and replace the pump if output is below spec.
Air in the line, a starved inlet from low feed pressure or a partly closed shutoff, or a worn rotary vane. We bleed the line, confirm inlet pressure is within spec, and inspect the pump head, quoting a replacement only if the rotary assembly is worn.
The OPV cartridge wears, and once the seat is grooved the valve weeps and brew pressure turns unsettled. We rebuild or replace the expansion valve, recalibrate against a portafilter pressure gauge, and confirm a flat 9-bar profile across the shot.
Each Storm SAE group runs its own PID and brew-side sensor, so drift means a sensor out of calibration or a PID offset changed without documentation. We measure brew water with a Scace device per group, recalibrate the offsets, and confirm stability across ten consecutive shots per group.
Scale insulating the steam-boiler element, followed by a drifting pressurestat, or a sensor fault on PID-controlled steam trims. We descale the boiler, measure element resistance and current draw, verify the pressurestat against a reference gauge, and replace whichever part is failing.
Either a brew-group seal leak, a cracked internal water line, or a drain-line blockage causing backflow. We pressure-test the brew circuit, clear the drain to confirm flow, and trace the leak to its source, replacing seals on the spot and quoting cracked lines first.
A failed solenoid coil, scale lodged in the valve seat, or a level probe scaled over and reading full when the boiler is low. We test the solenoid electrically, descale the valve, clean or replace the level probe, and verify the auto-fill cycle runs end to end.
Steam valve cartridge wear or scale on the seat lets condensate past. We rebuild the valve with a fresh cartridge and O-rings, descale the wand internals, and verify a fully dry shut-off across several steam cycles.
Either the steam boiler isn't reaching set pressure, descale and pressurestat, or scale has narrowed the steam-circuit bore. We descale the wand and circuit, verify boiler pressure under load, and clear the wand-tip jets, replacing eroded tips.
Flow-meter mineral buildup is the leading cause, with a worn-through dose-button membrane behind the rest. We pull the flow meter, clean the impeller, verify pulse output to the controller, reprogram doses against a calibrated shot glass, and replace the keypad membrane if it's intermittent.
We read the fault log through the service interface, identify the specific code, and address the root cause, whether sensor, relay, board, or solenoid. Software hangs clear with a controlled reset; hardware faults are quoted before we replace any parts.
Sensor wires fatigue at the strain relief, or the sensor itself drifts after years of thermal cycling. We test the NTC against the resistance reference table, inspect the harness for chafe, and replace the sensor if it's out of spec, recalibrating the group's PID after the swap.
Either the cup-warmer element has failed open-circuit or the thermostat is sticking. We measure element resistance, test the thermostat, and replace the failing component, verifying against a surface-temperature probe before sign-off.

Updated August 2026
On the Storm's saturated groups the head seal sits right against the brew chamber, so it wears sooner than a conventional gasket and weeps from the head. We pull the group, replace the head seal and dispersion screen together, check the saturated-group body for pitting, and pressure-test the seal under brew load.
Each Storm SAE group has its own PID and brew-side NTC, so a single drifting sensor or an offset changed without a note throws that group off. We measure brew water with a Scace device per group, recalibrate the PID offset, and confirm it holds across ten straight shots.
Most Storm codes point at a sensor, solenoid, or board rather than a catastrophic fault. We read the fault log through the service interface, identify the exact code, and fix the root cause, an NTC out of range, a flow meter not pulsing, a level probe scaled over. Software hangs clear with a controlled reset; hardware faults are quoted before we replace anything.
It's rated to around 350 shots per group, so a three-group will carry a serious specialty volume. What decides whether it holds that pace is upkeep, not the rating: saturated-group seals, clean flow meters, and on-spec brew pressure. Run it hard with skipped descales and faults arrive faster.
Usually a worn rotary pump, an expansion valve that has drifted, or a clogged inlet screen. We gauge the group with a blind portafilter, isolate the pump from the OPV, adjust the valve against a calibrated gauge, and replace the pump head if output is below spec.
Yes. Most lockups are a firmware hang that clears with a controlled reset and, where supported, a reflash from a known-good image. If the controller board or touch module has actually failed, it's a part swap, not a write-off, and we quote it before fitting.
They share a platform family. The Storm SAE carries saturated groups, twin PID, and SAE electronic dosing; the Tempesta is the competition-tier build of the same lineage, with programmable pre-infusion and a few extras. For service that means the core hydraulics and electronics are familiar across both.
Yes, both configurations. The extra group adds another PID, NTC, solenoid, and flow meter to check, but it's the same platform throughout. We service the per-group electronics and the shared boiler and pump side the same way on either size.
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 books a tech who knows saturated groups and twin PIDs cold.
