Impressa S9 problem
#1
Hi, forum!

I have a problem that has developed since about 2 months back but today it became a major problem.

First signs was that when I rinse the unit I felt that the amount of water coming out in the coffee pipes was not as much as it used to be but it felt a bit intermittent. Same goes for the coffee itself, doesn't come so much and some cups contain very little coffee and some more or less the normal amount (again, intermittent amounts).

The thing now is is that basically it comes only drops of water when rinsing and drops of coffee. It seems to affect the tea sprout as well. The steam function seems to be ok though.

I've openened the unit (done that before to clean from time to time as well as I've changed all the o-rings in the brew unit about 1,5 years ago), cannot see that the front detachable part with the Jura logo "sticker" is at fault from inspecting it.

Also, after several rinses, I can get coffee but it comes in drops and it takes ages to brew one cup (almost like the process was in slow-motion). Also the "pump" sound is not normal compared to when the unit is working normally.

The water comes out in the tray (not in the used coffee compartment).

Any ideas of what to look for?

Thanks in advance!

Is the coffee spout, coffee powder free? Ist the Crema valve in the brewing Unit (top) clean? You can also try decalcing your coffee machine.
Different quantities of coffee could be the Flowmeter. The Flowmeter measure the flow from the water.
If the pump sounds more quiete is something clogged after the pump. Is it more loud, then flows not enough water to the pump.

Thank you for your answer.
The coffee is basically powder free, always some tiny tiny amount comes in the cup but that's almost microscopic and very few.
The crema valve on the top is as far as I can tell clean (even though the hose is totally blackened).
The pump sounds a bit different, when the problem is "active" the pump is very quiet compared to when everything is working normally.
But the problem is intermittent. For example, yesterday evening the machine was on and I was sitting in the other room when I heard it shutting down (it shuts itself of after 3 hours of no use), then I could hear the normal sounds again, that is, the pump sounded quite good and also the water coming from the coffee spout. I then went ahead and cleaned the machine (with BND Kaffee Studios own tablets of course! :-) ) and run the water for a full cycle from the tea spout as well as steamed. It all went quite well but maybe not as good as when it works normally if I recall that correctly. Anyhow I did 3 full cleaning programmes with tablets just to run through the system as much as possible.

I will test to decalcify as you say and report back after that.

BTW, the service connector in front (as well as the loose cable hanging on the back where the PCB is, is that for connecting to a computer for troubleshooting? Is that something you sell and is that helpful to have?

Thanks!

Ran the decalcifying program now. Seemed fine during the run but afterwards it was status qou with the coffee spout (for coffee and when rinsing). The pump sounds good/normal so I'll have a go at looking before and after the pump (disconnecting the legris connectors I guess).

Is there a filter in the water tank? Then try to remove it.
I think there must be a blockage between the pump and the coffee spout.
Steam and Coffee are different ways. So the Steam-Side is okay, the coffee side not.
It´s not normal, that the pump is quiet.
I start from a calcification. A chunk of the purely dissolves and then reattached.

There is no Claris filter installed, we have very soft water here. Decalcifying has been run (see my previous post) but with the same results.

It feels like when I'm rinsing/making coffee most of the water comes in the tray (but not in the coffee waste bin) instead of the spout.

I have a new premium o-ring kit which I bought from you but the other kit I installed about 1,5 years ago and I can hear that the brewing unit sounds mechanically as it should, it sounds like when the machine was new.

If I don't find anything I'll try to post a video on YouTube or something if that helps?

Could not upload video as an attachment so I instead posted it on YouTube; http://youtu.be/CzzNksXwmno

Disregard the water in the coffee bin, it's because I didn't dry it afterwards I threw some waste coffee away.

I don't know how much it will tell but hopefully something. I can (easily) make another video of some other part or component if that's helpful.

Took out the pump and the membrane and inspected the parts, looks ok but of course hard to tell what's going on inside these parts.

Can I check something else? Should I make another video?

Should I order a pump and a membrane from you?

Thanks!

Maybe try to remove the hoses. From the coffee spout back to the pump. Then you can determine how far the water comes. I think there is something clocked. Ist there dirt in the Flowmeter?
