Jura automatic machines (E6, E8, ENA, S8, J8, Z10, GIGA) error codes
Jura uses the same numbered errors across its range. Errors 1 to 5 are the thermoblock heaters and their sensors, 6 is the ceramic valve, 8 is the brew group. Messages such as "Fill water tank" are separate and covered below.
Source note: Jura's own manuals define only Error 2 and Error 5 (the machine is too cold; warm it to room temperature) and tell you to switch off with the On/Off button and contact customer support for any other error. The other meanings here come from technician service tables, which number the GIGA line differently from the standard lines, so the same number can mean different things. Each page says which family it describes.
All codes
| Code | Meaning | Fault | DIY |
|---|---|---|---|
Error 1 | Coffee thermoblock temperature sensor fault (S/X/J/Z family); damaged sensor on F/E80 | thermoblock sensor fault | hard |
Error 2 | Machine too cold to heat (Jura manuals); technician sources also list a heating or sensor fault | sensor open or machine too cold | moderate |
Error 3 | Steam thermoblock temperature too low or its NTC sensor failed | steam thermoblock sensor fault | hard |
Error 4 | Steam thermoblock overheating or a defective sensor | steam thermoblock overheat | hard |
Error 5 | Machine too cold to heat (Jura manuals); technician sources list a heating failure | heater not reaching temperature | hard |
Error 6 | Electronic ceramic valve not operating correctly | ceramic valve fault | hard |
Error 7 | Ceramic valve / multi-valve or brew-group drive fault (valve did not reach its commanded position) | valve or brew-group drive fault | hard |
Error 8 | Brew unit cannot position or complete its cycle | brew unit cannot complete its cycle | hard |
Error 9 | GIGA: heating failure, brew temperature not reached. Standard lines: logic relay defective (per a third-party service table) | heating failure or relay fault | hard |
Error 10 | GIGA gen 1: left grinder sensor, no pulses. GIGA gen 2: power board or heating. Standard lines: heater too hot | left grinder sensor (GIGA) or heater overheat | moderate |
Error 11 | GIGA: grinder-side fault; sources disagree on the side and differ between GIGA generations | grinder fault (GIGA) | moderate |
Error 13 | Grinder will not initialise: GIGA gen 1 right, GIGA gen 2 left, standard lines left (per third-party tables) | grinder will not initialise | moderate |
Error 14 | GIGA gen 1: milk stepper motor; GIGA gen 2 and standard lines: right grinder. Will not initialise | stepper or grinder will not initialise | hard |
Error 16 | GIGA gen 1: multi-way valve; GIGA gen 2: hopper-vent stepper motor. No code 16 on standard lines | multi-way valve will not initialise (GIGA) | hard |
Fill water tank (tank is full) | Water tank message will not clear although the tank is full | false "fill water tank" message | easy |
Empty drip tray (tray is empty) | Prompt to empty the drip tray and grounds container, which can persist after emptying | drip tray message will not clear | easy |
Error 12 | Grinder failed to activate: motor seized or burrs impeded, often by a stone; sources disagree on left or right | grinder jam or motor fault | moderate |
