About these codes. Compiled from JURA Canada and global professional-machine documentation, cross-checked against our GTA repair logs. Updated August 2026

Brew unit

5 codes
Error 8 Brew group / brew unit fault Critical

The brew group failed to complete its motion cycle. The encoder didn't read the expected motor revolutions. This is the single most common Jura fault.

Likely causes

  • Coffee grounds jamming the brew piston
  • Worn brew group cam followers or gears
  • Failed encoder
  • Failed gear motor

Try this first

  1. Unplug the machine for 5 minutes (resets the cycle position).
  2. If your model has a removable brew group, take it out, rinse it warm, and reinstall.
  3. Lubricate the brew group if it's been a while (Jura-safe grease only).
When to call us

If Error 8 comes back within a day, the brew group needs refurbishment or replacement. We see this regularly at 2,000+ cycles. Call us.

Call about Error 8
Error 9 (GIGA) GIGA brew unit secondary fault Critical

On GIGA models, a brew-unit cycle fault distinct from Error 8. Indicates the secondary brew unit (GIGAs have two) or a different stage of the brew cycle failed.

Likely causes

  • Second brew unit jammed
  • Worn drive components on a high-volume GIGA
  • Cross-contaminated grind buildup

Try this first

  1. Unplug for 5 minutes.
  2. Power back on and run a rinse cycle.
  3. Document which side of the GIGA is misbehaving if observable.
When to call us

GIGA brew units work hard, so they need service sooner than a single-brew Jura. If the code returns after a power-cycle, book us in.

Call about Error 9 (GIGA)
Error 15 (GIGA) Coffee chute / dosing fault Warning

Coffee delivery from the grinder to the brew chamber failed, or the bypass doser (for ground coffee) is blocked.

Likely causes

  • Pump worn (most common at high cycle counts)
  • Internal leak bypassing pressure
  • Pressure sensor failure
  • Scale restricting flow

Try this first

  1. Power-cycle.
  2. Try a hot water dispense and listen to the pump.
  3. Note whether coffee is also weak (correlates).
When to call us

If the brew stays weak after a power-cycle, the pump likely needs replacing. It's a common service item past 3 years of heavy use; call us.

Call about Error 7
Error 22 Smart water filter not recognized Warning

The machine can't detect the CLARIS Smart filter in the water tank. Filter recognition is RFID-based: a small reader in the tank housing checks the tag on the cartridge, and when that handshake fails the machine reports Error 22 and stops tracking filter life.

Likely causes

  • Expired or defective CLARIS Smart filter cartridge
  • Non-genuine (non-OEM) filter without a working RFID tag
  • RFID sensor damaged, often by water spilled while refitting the tank
  • Faulty RFID antenna coil between the sensor and the board

Try this first

FAQ

Jura error codes, frequently asked.

9 answers about resetting codes, recurring faults, firmware versions, and when DIY ends. If the recurring ones are descale or water warnings, start with the right Jura water filter.

Updated August 2026

What does Jura error code Error 1 mean?

Every documented Jura 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.

Can I clear or reset a Jura error code myself?

Sometimes. Many Jura 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.

Why does the same Jura error keep coming back?

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.

My Jura code isn't listed. Why?

Jura 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.

How fast can you get on-site if I'm stuck on an error code?

Most calls in Toronto and the immediate GTA get same-day on-site response. 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.

Do I need to be authorized by Jura to reset an error code?

No. We're an independent service provider, not affiliated with Jura, 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.

Is it worth fixing an old Jura machine that keeps throwing codes?

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.

Will independent service void my Jura warranty?

If your machine is under the manufacturer's warranty, independent service may affect coverage depending on Jura'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.

How many Jura codes are documented on this page?

29 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.
