Jura Professional Coffee Machine Error Code 2 / Error 5: Machine Too Cold
Error 2 or Error 5 can appear when the machine has been exposed to cold for a long time, because heating may be disabled for safety reasons. Let it warm to room temperature. If the message stays, switch it off with the On/Off button and contact customer support.
Medium: heating is disabled, but a warm-up often clears it.

What does Jura Professional error 2 / error 5 mean?
The heating system of a coffee machine is not allowed to run when its own temperature is far below normal, so the control disables heating if the machine has sat in the cold for a long period. In that case the display shows Error 2 or Error 5 (ERROR 2 or ERROR 5 on the WE8). The manual explains this one reason and says the cure is to warm the machine at room temperature. It does not list the other Error messages individually: for those, the instruction is to switch the machine off and contact customer support. So this page covers the cold-exposure case, and an Error 2 or 5 that stays after the machine has warmed up is outside what the manual describes. The machine is not stopped for a clear reason you can fix other than temperature. A delivery left on a cold dock overnight is a typical trigger.

Possible causes
Listed in Jura Professional's documentation
- Machine exposed to the cold for a long period of time
Other likely causes — what usually sits behind error 2 / error 5 on this control. A technician confirms which one it is before any part is replaced.
- Machine still cold inside after only a short warm-up
- Unit placed in a draft near an outside door or loading area
- A different Error cause that the manual does not list individually
Safe checks before calling for service
- Move the machine to a room at normal temperature and leave it there for a few hours.
- Switch it on again and see whether the message clears.
- If it stays, switch off with the On/Off button, as the manual instructs.
- Keep the machine away from drafts and cold walls afterward.
- Note how the machine was stored or moved before the message, and tell the technician.
How a technician diagnoses error 2 / error 5
- Read the display and confirm Error 2 or Error 5 on the specific model.
- Ask how the machine was stored and how long it has been at room temperature.
- Check the heater and temperature sensing for open circuits once the machine is at room temperature.
- Check the supply and the heater safety devices.
- Replace the failed part only after a meter test, then verify the machine heats.
- The heater and its safety devices are wired at line voltage.
- The manual does not list individual meanings for other Error messages, so a technician has to test the machine.
- Temperature sensing and heater circuits need a meter.
How error 2 / error 5 differs from similar codes
