Error code reference
If your Dalla Corte is flashing a code mid-service, this page tells you what the machine is trying to say. Because every group carries its own boiler, sensor set, and PID, most coded faults point at one specific group rather than the whole machine, which is good news: the rest of the bar usually keeps pouring while you sort it out. Find your code below, run the safe checks, and call us when it crosses into tech work.
We'll get back to you today with what it likely is.
Thanks. We received your request.
A Grajqevci technician will get back to you today to confirm your machine and book the visit. If it's urgent, call us directly at (289) 217-3796.

About these codes. Compiled from Dalla Corte service documentation, Franke parts portal references, North American distributor support, and our own service log. Display wording shifts between XT, Zero, and Evo2 firmware generations, so treat each entry as the family meaning. If what your machine shows doesn't match exactly, call us with the exact text. Updated July 2026
One of the boilers didn't reach its setpoint inside the heat-up window, and the display tells you which one.
Element testing and SSR diagnosis is technician work. When we come out we check every boiler, not just the one that timed out.
The controller commanded a brew cycle on a specific group and didn't see the expected actuation or flow.
On the XT the brew solenoid sits alongside the flow regulator, so this is panels-off work. Call us; don't bypass anything.
The pre-infusion solenoid on one group isn't actuating in the expected sequence.
Pre-infusion solenoids are per-group on these machines. We test the coil and the driver, then replace or descale whichever is at fault.
The flow meter on one group isn't sending pulses during a shot. On the XT, the real-time weight system can stand in for flow metering on profile shots, so dose-by-volume may be disabled while weight is in use.
A meter swap is quick, but it's a planned tech visit. Until then, manual mode on the affected group keeps you serving.
The main controller has lost contact with a group board, the UI module, or the scale module.
Boards come through the Franke parts network and lead times can stretch, so call early and we'll confirm availability before the visit.
On the XT, the real-time scale isn't registering weight changes, or its load-cell readings are jumping around.
Re-zeroing and recalibration with reference weights is tech work, and load cells are precision parts. If cleaning the platform doesn't settle it, book the visit.
Autofill ran past its safety window without the level probe registering full, and the display identifies which boiler. The machine stops filling to protect the pump.
Each boiler has its own probe and inlet solenoid, so this needs multi-boiler diagnosis rather than a single-boiler guess. If there's water under the machine, mention it when you call.
On the Mina and XT with manual flow regulation, brew pressure isn't following the expected profile during the shot.
The manual flow regulators use precision needle-valve geometry, and disassembly is service work. If the lever binds, stop using that group and call.
The NTC temperature probe on Group 1's brew boiler is reading open or shorted, so the controller locks that group out. The other groups stay live.
The probe needs testing at the controller, and after replacement the group's PID offset has to be re-baselined with a Scace device. Both are service-call work.
Same family as E01, one group over: the NTC on Group 2's brew boiler is out of range and Group 2 locks out.
Group 2 needs probe testing and likely replacement, then a PID re-baseline. Call us and keep pouring on the groups that still work.
The NTC on Group 3's brew boiler is out of range. On a 3-group rotation Group 3 often works hardest, so slightly faster probe wear is normal.
Probe testing and replacement, the same procedure as E01. It's a service call, not a counter-side fix.
The steam boiler's NTC probe is out of range, so the steam side locks out while the brew groups stay live.
Steam-side probes run hotter and fail sooner than brew-side ones. Replacement is service-call work, so book it rather than power-cycling around it.
A maintenance counter has hit its threshold: shots pulled, water volume, or descale hours. It's a reminder, not an active fault.
Dalla Corte's brew-boiler service intervals are deliberately aggressive, and stretching them shows up later as scale damage. If you want the interval changed, have us confirm your water quality first.

Every documented Dalla Corte fault we see is listed above, with its meaning, common causes, and what to try before calling a technician. If the code on your machine isn't on this page, call us with the exact display string and we'll work it out by phone.
Sometimes. Many Dalla Corte codes clear after a power cycle, a completed descale, or a counter reset through the service menu. Codes tied to a hardware fault (failed sensor, blown element, board issue) will return immediately and need a technician. Each code above lists what's safe to try first.
A code that returns after a power cycle is signalling a real fault, not a glitch. The underlying part (sensor, heating element, valve, motor, board) needs replacement. Repeat codes are diagnostic gold for us, so call with the exact code and any timing or symptom pattern you've noticed.
Dalla Corte updates fault tables across firmware revisions and model generations, and not every code is documented publicly. We see codes in the field that aren't in any published list. Call us with the exact display string and the model and we'll work it out from our service log.
Most calls in Toronto and the immediate GTA get same-day on-site response when scheduling allows. Tell us the code and the model when you book and we'll bring the right parts on the first visit so the repair finishes the same day in most cases.
No. We're an independent service provider, not affiliated with Dalla Corte, and we work on machines outside the manufacturer's authorized network routinely. That independence lets us service older or out-of-warranty machines authorized networks may decline, and quote transparently every time.
Depends on the machine, the code, and the cost. We give you honest math on this. If repairs are starting to exceed roughly 50% of a refurbished replacement and multiple major systems are throwing codes, we'll tell you it's time to look at replacing rather than running up the repair bill.
If your machine is under the manufacturer's warranty, independent service may affect coverage depending on Dalla Corte's specific terms. Try the manufacturer's authorized network first. If their response is slow or they decline coverage for your code, call us and we'll service it on standard terms.
13 codes are documented above, organized by the system they affect. The list is compiled from manufacturer service literature, technician forums, and our own service log. We update it as new codes appear or firmware adds new states.
Track record
Two of our property's espresso machines went down the morning of a corporate breakfast for 200. Their team had both running before service started.
We diagnose Dalla Corte codes by phone routinely. Same-day on-site dispatch if it needs hands on the machine.
