Hi

Excuse me posting here in English, but my German is not good, and this seems to be a very good forum for Jura technical topics. Please reply in German - I can use Google translate to help me!

I have a problem with a leak from the outlet valve/Auslaufventil - see the picture. The coffee maker still works, but there is always water under the machine after each coffee.

I have already fitted a new silicon tubing and new hose clamps (new
Silikon Gewebeschlauch and new Schlauchschelle, Sicherungsblech und Klemmfeder). This made a small improvement only. The problem happens under the high pressure only, when putting water into the espresso brewer.

Any ideas on what other problems it could be? I checked to see if the outlet valve/Auslaufventil is cracked, but it looks OK, and I see the water coming from the connection. Maybe is the pressure too high? Or do I have another problem in the fluid system that is causing this leak. Any suggestions are helpful.

Thanks, Andy

Thanks, BS. I did not see any problem with the tubes, and they seemed to slide onto the Auslaufventil quite easily.

So is there some special tip for fitting the tubes? - I have a meter of silicon tube so can easily cut a new piece and try again.

Or is it good to try some silicon grease or silicone sealant to make a good joint?

I did eventually change the Auslaufventil and that fixed the problem. There was a hairline crack, although I could not see only. It only leaked when under pressure.

Thanks for your help, BS
