Wega down behind the bar?
Wega gone quiet mid-shift and a line forming? We repair the whole traditional range, Toronto to Hamilton: the Polaris and Polar flagships, the Nova, Urban, Airy, Rover, Pegaso Plus, IO, and compact Mininova, plus the older Concept, Atlas, and Orion machines still on the bar. A group that will not seal, steam gone weak, a PID drifting, an Err code that survives a restart: tell us the model and the symptom and we usually know the fix before we arrive.

Wega builds traditional Italian espresso machines with real group heads and steam wands a barista drives. They turn up everywhere from neighbourhood cafes and bakeries to busy hotel bars, in single-group compacts up through four-group multi-boilers. Sharing so much with Astoria, they are tidy to work on: the common faults are predictable wear, group gaskets, steam-valve cartridges, scaled elements, and the odd drifting flow meter, rather than anything exotic. The ones that get regular descaling and seal work clear 12 to 15 years without drama.

Wega faults we diagnose
These are the Wega faults that actually book service calls, from group leaks and steam drips to PID drift and EVD dose problems, each with its cause and the fix.
A group gasket gives up around the 12-to-18-month mark on a busy Wega, so a leak here is wear rather than a defect. We pull the group, swap the gasket and dispersion screen as a pair, clean up the threads, and pull several shots to confirm the seal holds under full brew pressure.
Channelling usually traces to coffee oil and fines baked onto the screen, which breaks up even water dispersion across the puck. We fit a fresh screen, backflush the group with detergent to clear the rest of the path, and check for even flow across the screen face before it goes back together.
Pressure that will not climb to 9 bar usually means a tired rotary pump, a drifted OPV (expansion valve), or a clogged inlet screen. We gauge it with a blind portafilter to pin down which, set the OPV against a calibrated gauge, and if the pump itself is below spec we quote the replacement before swapping it.
A pump that hammers or starts hard is usually fighting air in the line, a starved inlet, or a worn rotary vane. We bleed the line, confirm the inlet pressure reaching the machine sits within spec, and open the pump head to check the vane. A worn rotary assembly gets quoted for replacement.
PID-controlled Wega platforms carry a temperature offset per group, and those drift as the sensor ages or after someone changes them in the service menu without writing it down. We read brew-water temperature at each group with a Scace device, reset the PID offset to spec, and watch it hold across 10 consecutive shots before calling it done.
Nine times out of ten the culprit is scale wrapped around the heating element, with a drifting pressurestat the next suspect. We descale the boiler, measure the element's resistance and current draw, compare the pressurestat against a reference gauge, and replace whichever one reads out of spec.
Green Line firmware runs an energy-saving pressure profile, so the boiler deliberately lets pressure vary, which throws operators expecting a flat reading. We confirm the firmware is in the mode it should be, check the pressurestat and PID calibration, and if nothing is actually wrong we walk your team through what the eco cycle is doing and why.
Water on the floor is either a brew-group seal letting go, a cracked internal line, or a blocked drain backing up into the tray. We pressure-test the brew circuit, clear the drain, and follow the water back to its source. Seals go in on the spot; a cracked line gets quoted before we replace it.
If the boiler will not fill, the inlet solenoid coil has failed, scale has seized the valve seat, or the level probe is scaled over and falsely reporting full. We test the solenoid electrically, descale the valve, clean or replace the probe, and watch the auto-fill cycle run start to finish before signing off.
A wand that keeps dripping with the valve shut points at a worn steam-valve cartridge or scale on the seat. We rebuild the valve with a new cartridge and seals, descale the wand internals if scale is part of it, and cycle the valve several times to confirm it shuts off dry.
Weak or spitting steam comes down to a boiler that is not holding pressure, or scale narrowing the bore through the steam circuit. We descale, confirm the boiler holds pressure under load, and clear the jets in the steam tip. An eroded tip gets replaced rather than cleaned.
When volumetric shots start overshooting, mineral buildup on the flow meter is almost typically behind it. We pull the meter, clean the impeller, confirm a clean pulse signal back to the controller, and reprogram the doses against a calibrated shot glass. On normal volume that calibration holds 6 to 12 months.
A frozen display or a posted error code is the machine telling you something upstream tripped, so we start in service mode and read the fault history to find the actual code. From there we trace it to the root, whether a sensor, relay, solenoid, or board, fix that, clear the log, and run every group through a full test before we pack up.
Plenty of shops turn away first-gen Atlas, Orion, and older Polar machines; we do not. CMA keeps a deep parts catalogue for older platforms, and because Wega and Astoria share so much, a current Astoria part often drops straight in. When a part is genuinely gone we source it through refurbisher networks, and if the repair stops making economic sense against a newer machine, we will tell you straight.

FAQ
19 answers covering service, repair, parts, installation, warranty, and edge cases.
Updated July 2026
Yes. Wega is a regular on our bench, both the current Polaris, Polar, Nova, and IO machines and the older Concept and Atlas units. We cover Toronto and out through the Golden Horseshoe, and because we also service Astoria, the shared parts are usually already on the van.
No, and we say so plainly. We are an independent commercial espresso specialist, which means we work on out-of-warranty machines, keep discontinued Wegas running after the official channel moves on, and quote against the actual job rather than a manufacturer price book.
Group and steam wear, by a wide margin. Group gaskets give 12 to 18 months on a busy bar, steam-valve cartridges start dripping, and elements scale up on the region's hard water. None of it is dramatic, and most of it is sorted in a single visit from parts on the truck.
Yes. The Polaris and other PID Wegas carry a temperature offset per group, and those drift as sensors age. We read brew water at each group with a Scace device, reset the offset to spec, and confirm it holds across ten consecutive shots before we leave.
It can be either, so we check the machine before blaming the barista. Scaled brew temperature, a drifted pump, or a worn group screen all skew the shot, and those are ours to fix. If the hardware tests in spec, the answer is grind and recipe, and we will tell you that honestly rather than sell you a part.
A flat rate covers the visit and diagnosis, which you hear when you book, and parts are billed on top at cost. Anything larger than a routine fix gets a written quote on-site before we touch it, so the number never balloons mid-job.
The fault statistics decide it: group gaskets and dispersion screens, steam-valve cartridges, pressurestats, O-rings and seals, flow meters, and level probes. Because Wega and Astoria overlap so heavily, one stock of common parts covers both, which is why most calls finish in one trip.
Yes, that is bread-and-butter work. A full group service means new gaskets and screen, a rebuilt or replaced solenoid where needed, and the steam valve gone through, then everything tested under brew pressure. On heavy multi-group machines we do them as a set so they all behave the same.
Most calls placed in the morning see a technician the same day, with later ones booked for the next business day. A cafe with a dead bar and a queue gets bumped up the route. Tell us the model and the symptom when you call and the van leaves with the likely parts loaded.
Usually worth repairing. Wega builds last 12 to 15 years with service, and most faults are seals, valves, or a pump that cost a fraction of a new machine. We give you the repair number and an honest read on what is left in the machine, and if replacement genuinely wins we say so.
Yes. We keep first-gen Atlas, Orion, and older Polar machines running long after other shops turn them away. CMA's parts catalogue stays deep for older platforms, current Astoria parts often drop straight in, and where something is truly gone we source from refurbisher stock.
If the fault is covered, the official channel should fix it at no cost, and we will tell you that on the phone. A lot of what actually fails, scale damage, worn consumables, milk and steam hygiene, sits outside most coverage, and that is the work we handle every week.
Yes, and most cafes move to a schedule once they have seen a visit. Regular descaling, seal checks, and a steam-valve service are what keep a Wega off the critical error codes. We size the interval to your volume and your local water rather than a generic calendar.
No. We work call by call, and a maintenance schedule is always your choice after you have seen the work, never a condition of getting help. Plenty of operators start with one repair and stay because the work holds up.
We can. Much of the region runs moderately hard water, and York Region and Hamilton harder still, which is what scales elements and seizes level probes. We descale on the visit, check your filtration, and recommend a softening cartridge and a realistic descale interval for the water you actually have.
Yes, multi-site is routine. One booking can take in every bar across your locations, with a single report listing what each machine needed. Across a fleet we also spot patterns: when three bars share a fault, the cause is usually the water or the cleaning routine rather than the machines.
Yes, and we do it on the way out by default. Half of repeat faults trace back to a skipped backflush or a wrong cleaning routine, so the technician walks your team through daily steam-wand care, group backflushing, and what a drifting shot is trying to tell them.
Both are multi-boiler flagships, so the boiler, group, and pump work is similar. The Polar adds a 3.5-inch touchscreen, Autosteamer Plus steam profiles, and the SmartGrind wireless link, which brings a few electronics-specific faults the Polaris does not have. We service both and carry the diagnostic experience for each.
Have the model and any error code ready, and note when the fault shows up, on the first shot, under steam, or only at peak. If you can, leave the machine on so we can see the fault live. A photo of the display or the leak when you book helps us load the right parts before we set out.
About Wega
Reviewed July 2026
Wega is one of two flagship brands made by CMA Macchine per Caffe, the Italian manufacturer that runs what is widely cited as the world's largest single coffee-machine plant. It shares a factory and most of its engineering with sister brand Astoria, but keeps its own look and sits a notch closer to the value end of the range.
Wega Macchine per Caffè was founded in 1985 as the second brand of CMA Macchine per Caffè, which had been producing Astoria machines since 1969. The brand is headquartered alongside Astoria at CMA's 20,000-square-metre facility in Susegana, Treviso, in the Veneto region. CMA (and therefore both Wega and Astoria) was acquired by Milan-based holding company Ryoma in October 2012.
The Polaris is Wega's design-forward flagship with PID temperature control and a distinctive aerodynamic body with side RGB lighting on current generations. The Concept (and its Green Line variant) sits in the energy-conscious mid-tier. The MyConcept brings customizable side panels and modern controls to the same platform. The Atlas, Pegaso, and Vela serve high-volume café programs with multi-boiler architecture on top trims. The IO is a more value-tier commercial machine in EVD (electronic) and Tron (volumetric) variants, and the Mininova brings the platform into compact and one-group footprints.
The current lineup runs from the compact Mininova Classic and entry-level Wbar Pro up through the Nova, Urban, Airy, Rover, Pegaso Plus, and IO, to the multi-boiler Polaris Pro and Vela Vintage and the touchscreen Polar flagship. We also keep the discontinued Concept, Atlas, Orion, and Sphera machines pouring for the cafes still running them.
Wega shares its hydraulics and electronics with Astoria, down to the same pump suppliers, similar pressurestats, and comparable group designs on equivalent trims. The platform still has its own quirks, though: the Polaris's PID implementation, the Concept's energy-saving pressure logic, the IO's volumetric flow-meter behaviour. A technician who only knows one Italian commercial brand often does not know how the next one differs. We service both Wega and Astoria across the GTA, so we know the shared parts and the brand-specific ones.
