Our Jura coffee machine S9 model has error message Malfunction 4 appearing, have turned machine off from power swith and left off for 30 secs, still has same error message.

It doesn't appear that you can. If there was, Google would know it.

Nothing here either

Have you tried turning the power switch on the back left of the machine on and off?

The Owner Manual for the Jura Impressa S9 One Touch identifies Error 2 as being too cold and disabled for safety, but simply instructs to "Turn the IMPRESSA off at the power switch. Contact Customer Support in your country." for all other errors.

Hi, Error 6. Haven't come accross that one before. It sounds like brew unit problem.I do know error 7&8 are brew unit problems and 1 to 5 are water flow and heating errors. Try turning off the machine at the main power button and unplug it from the wall for a few minutes. This will reset the machine and right it self. They can do this from time to time. Dazza

There is a Jura Error Guide that says:

• Turn machine off, turn the main power switch off and unplug machine for at least one minute.
• Turn machine on again. If the error message comes up again, try one more time.

This is a really strange error, but it makes some sense if you own a S9 One Touch model. Then there`s a problem with the squeezing valve located behind the steam/cappuccino outlet. If this is an older model, then it could be a problem with the ceramic valve, but normally this makes the water flud all over the frontpanel and inside. In both cases, i would recommend to send the machine to the nearest servicecenter.

If you have a rotarywheel; Press and hold to enter the menu, turn to Maintenance, select Decalcify unit; empty tray as requested, fill up 600ml water in a container. Disolve 3 Descaling tablets in the water, and then fill it in the watertank. Press Maintenance button and you`re off.

If you don`t have a Rotary; Turn off the machine and let it cool down for a while, then push the Rinse/Maintenance button for a few seconds; then you will get the message Empty tray. Fill the solution in the watertank and press button.

It`s important that you use the right amount of water, or else the process will "never" finish.
