How to fix Error 13
- Switch off with the On/Off button, unplug for five minutes, then restart once. A transient fault can clear.
- Empty the bean hopper completely, look for stones or clumped beans, and vacuum the hopper outlet and grinder throat with a plastic nozzle. Never push metal into the burrs.
- If it returns, stop and follow Jura's own instruction: contact Jura customer support or an authorised service centre.

Beyond the fix
Tips and tricks
- Check for a stone or foreign object in the bean container. A parts seller says a seized motor or impeded burrs, most often from a stone, trigger this code.repair guide
- Remove dirt and foreign objects from the bean container when refilling, and use only untreated roasted beans, as the GIGA manual says.manufacturer manual
- If the grinder is clear and the error stays, a technician must test the grinder, cables and boards. Do not open the machine.repair guide
Common mistakes
- Assuming the side from the number alone. Standard lines list 13 as the left grinder in the German table.
- Feeding additive-coated beans, which the GIGA manual says damage the grinder.
Easily confused with
- Error 14 is the cappuccino stepper on first-generation GIGA machines but the right grinder on second-generation ones.

Questions
What does Error 13 mean on the Jura?
Grinder will not initialise: GIGA gen 1 right, GIGA gen 2 left, standard lines left (per third-party tables). Jura's own manuals define only Errors 2 and 5 and tell you to switch off with the On/Off button and contact customer support for any other error. The meaning below comes from a third-party technician service table, which numbers GIGA and standard machines differently. The table gives opposite sides for this code: on GIGA machines Error 13 is the right grinder failing to initialise, on standard lines it is the left. Jura-parts.com, a US parts seller, adds that this is true of first-generation GIGA machines only; on second-generation GIGA machines it lists Error 13 as the left grinder. We cannot tell you which generation your machine is. The machine tried to home the grinder at startup and did not see it move, which usually means a jam or a failed grinder drive.
Can I fix Error 13 myself?
DIY difficulty: moderate. Switch off with the On/Off button, unplug for five minutes, then restart once. A transient fault can clear. Empty the bean hopper completely, look for stones or clumped beans, and vacuum the hopper outlet and grinder throat with a plastic nozzle. Never push metal into the burrs.
How much does it cost to fix Error 13?
Not published by Jura. Grinder motors are typically a service-centre part. Service prices are not published by the manufacturer. Ask an authorised service centre, and an independent espresso repairer, for a quote.
Is it worth repairing?
Usually yes on higher-end machines; get a quote first.
When does Error 13 typically show up?
Juras report Error 13 any. That timing is a useful clue when narrowing the cause.
Can I keep using the machine with Error 13 showing?
Usually you can finish the drink you are making, but do not ignore it — the underlying fault rarely heals itself. Work through the cheap checks first.
Will Error 13 clear on its own?
Sometimes. Try the reset and cleaning steps first — they cost nothing and clear the milder cases. A code that returns within a day or two needs the parts fix.
How long does the repair take?
Thirty minutes to an hour if you are comfortable opening the case; budget an afternoon the first time.
