Expert guide to diagnose and fix "not turning on" on Jura machines.

⚡ TL;DR — Quick Answer

Check that the 🏔️ Jura power cord is firmly seated in both the machine and wall outlet.

What Causes Not Holding Temperature?

Jura machines use pulse extraction technology and are sensitive to water hardness settings.

Step-by-Step Fix

Follow these steps specifically for Jura machines:

  1. Check that the 🏔️ Jura power cord is firmly seated in both the machine and wall outlet.
  2. Test the outlet with another device. If the outlet has power, inspect the Jura power switch for damage.
  3. Perform a hard reset: unplug the Jura machine for 60 seconds, then reconnect. This clears temporary control board faults.
  4. If still dead, the internal thermal fuse or power supply module may need replacement. Contact Jura service.

Frequently Asked Questions

Temperature that drops quickly points to scale on the boiler or a failing thermostat. Scale builds up inside every coffee machine and eventually blocks the boiler and pipes. Run a full descaling cycle with Jura's approved descalant every 2-3 months (or whenever the machine prompts it), then rinse with fresh water. If your machine refuses to descale, see our Not Holding Temperature guide.

The quickest way to fix scale problems on a Jura is a full descaling run: use the approved descalant, follow the machine's cycle, and finish with two rinse brews. Repeat every 2-3 months, or as soon as the alert appears. Step-by-step instructions are in our Not Holding Temperature guide.

If a Jura has not been descaled for a while, limescale restricts the boiler and pipes. Buy the brand's descalant, run the descale program, rinse thoroughly, and schedule it every 2-3 months from now on. See our Not Holding Temperature guide for the full routine.

A Jura prompts for descaling based on water hardness and usage. The fix is simple: run the descale cycle with approved descalant, rinse twice, and use filtered water to make the intervals longer. Details in our Not Holding Temperature guide.
