Jura descale e8
When ‘Descaling’ appears in the Cockpit. Takes about 20 minutes; do not interrupt it.
You need
- 3 JURA descaling tablets
- 500 ml of water
- 2 receptacles
Steps
- Hold the maintenance/settings button for about 2 seconds to open the JURA Cockpit.
- Press ‘Descaling’, then ‘Start’.
- At ‘Empty drip tray’, empty the drip tray and coffee grounds container and refit them.
If the descaling agent comes into contact with the skin or eyes, this can cause irritation. Avoid contact with the skin or eyes. Rinse off the descaling agent with clean water. Should you get any descaling agent in your eye, see a doctor. If the descaling agent comes into contact with sensitive surfaces (e.g. marble), damage cannot be ruled out. Clean up any splashes immediately.
