I make this post as a public service, from one person who could not find answers to the “System Filling” error on a Jura super-automatic.

Weeks ago my Jura C9 displayed the message “Change filter”, prompting me to put in a new Claris filter. I am not sure if I missed a step or did it wrong, but all of a sudden I kept getting the error message “Press Rinse” followed by the message “System Filling” and nothing happening. Over and over and over and the terrible loud grinding noise making me cringe (and I stood there envisioning a pump burning out).

Searching the message boards delivered few clear results and no action. The feedback from the Jura helpline in Switzerland was to do the following:

  • Fill your water tank with hot water (not boiling) and press the rinse button a few times. That may have worked if there was an air bubble in the line.
  • The way to prevent air bubbles with the Claris filter is by emptying the water, putting in the new filter, refilling the water and going through the filter rinse cycle.

In my case, no joy. I tried to call Canada help (because there is no Jura dealer in Japan) but each time I was too late (Jura closes at 5PM in Canada, 6AM in Tokyo). Very frustrating. So I emailed them and a technician emailed me back suggesting I call in. I explained my time zone issue and he did the amazing, he sent me his cell phone and said he would help me after hours. We talked at length and he helped me solve my problem.

Now, for those of you who have a depot nearby, I would probably not do this. I would take it in for service as it required opening the machine.

But if you are stuck like me (No depots in Tokyo), then chances are if you have this problem and a Claris filter installed, some carbon came loose and jammed the tiny little micro-filter inside your machine. Here is how you fix it:

First – pop the side off your Jura. This is what mine looks like – looking at the right side.


Looking at the side panel in the bottom left there is a pump. It looks like this.


Pull the little metal clip out and pull the plastic pipe out. Next, the “cream” coloured piece where you removed the pin from needs to be removed. You do this by “unscrewing” it from the white piece which goes into the boiler.

Below is what it looks like with the cream piece removed.


Now take that little piece with the micro filter and attach it to a compressor and blow it out. Trying to do this manually will not work (i.e. blowing in it). I had to drive to a gas station and use their compressor to truly get the bits out as my compressor is in my father-in-laws garage.

Then simply reinsert. Turn on the machine and the boiler should prime and you are good. Once confirmed, put the sides back on. I have had 2 Juras and used filters in both with this never happening. Hopefully it never happens again.

To avoid it in the future, empty the water container first, put in your new Claris filter, add water and then turn on the machine (in other words – follow instructions) and pray that random carbon chunks do not leak out.

Hopefully this helps someone.



I am a big coffee fan. Not really the Starbucks kind, more of the ‘hanging out at home using my machine’ kind.

Last week I made a big upgrade purchase – a Jura C9 – as my old Jura (circa 2007) has a UK power supply and when we move, I am not sure I can jerry-rig a solution. My impression? Amazing. I bought my first Jura for the automatic milk frother. Personally, I find frothing milk an arduous task that rarely turns our right and I am not about to get a part-time job at Starbucks so that I can learn to do it the right way on their $20,000 machine.

Not so with a Jura, it is a no brainer. Place the tube into a milk container, turn the dial and voila – a perfectly made cappuccino. The C9 takes it a step further; simply press the button and it froths the milk and then drops in the shot of espresso, following it up with an automatic clean cycle. Doesn’t get much easier than that.

Along the way I came across another find – Bodum double walled glasses. The issue with a traditional coffee mug is that the porcelain absorbs the heat from the coffee – cooling it quickly. The new double wall mugs keep the heat just like a thermos – no loss from a cold hand or from the side wall materials. I bought the espresso and the Pavina glasses/mugs – a cappuccino through a clear glass mug looks fantastic.

Now, where is that guilty pleasure – the Guardian – lying? (smile)
