Choose the warning shown on your machine. Check the model number and compare the full pattern with the manufacturer’s instructions before trying a fix.
Select your brand, then confirm the exact model and full code or light pattern. Indicator lights can change meaning when they flash instead of staying on. This database distinguishes manufacturer-documented meanings from possible causes; it does not diagnose an internal component from a display alone.

Displayed code
ERROR 8
What it means
The E8 reports a fault that needs diagnosis. Public E8 documentation does not establish one failed part from this number alone; E8 model generations differ.
Possible causes
- An interrupted start or internal positioning problem may be involved.
- An internal drive or sensor fault is possible, but the display alone cannot confirm it.
What you can check yourself
- Note the entire message, model generation and any abnormal noise.
- Make sure the external tray and grounds container are correctly seated.
Diagnostic sequence
- Use the power button to switch off and let the machine stop.
- Disconnect power briefly only after normal shutdown; inspect only removable external parts.
- Restart once and record whether the same message returns.
When to contact service
Arrange JURA service if ERROR 8 returns, movement is blocked, or grinding noises occur. Do not force the internal brew mechanism.
The official product support identifies E8 variants and manuals; component-level causes are possibilities, not a manufacturer-confirmed definition of ERROR 8.
