Jura Error 10 – meaning and fix

Applies to: automatic machines (E6, E8, ENA, S8, J8, Z10, GIGA).

Short answerJura'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. Jura-parts.com, a US parts seller, splits the GIGA line into a first and a second generation and gives different meanings for them. On first-generation GIGA machines Error 10 is the left grinder's Hall sensor giving no pulses, meaning the grinder did not turn, and a second source agrees. On second-generation GIGA machines the seller instead lists a power board or heating threshold fault. On standard lines the German service table lists the heater running too hot. We cannot tell you which generation your machine is. Some retail blogs call Error 10 a milk-system fault; no technical source supports that.

How to fix Error 10

Switch off with the On/Off button, unplug for five minutes, then restart once. A transient fault can clear.
On a GIGA with a grinder fault: switch off and unplug, 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.

Common mistakes

Taking retail blog claims of a milk-system fault at face value. The technical sources we read describe a grinder sensor.
Reading a standard-line table for a GIGA. The German table lists Error 10 as a heater running too hot there.

Standard lines use Error 10 for a heater that ran too hot, per the German table. Error 11 and 12 are the neighbouring grinder-side codes on GIGA.

When does Error 10 typically show up?

Juras report Error 10 any. That timing is a useful clue when narrowing the cause.

Can I keep using the machine with Error 10 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 10 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.
