I have problems with my jura capresso f60, it no longer makes coffee, it grinds the beans, but no liquid comes out. On the screen it says open tap, we have no idea how to fix this.

Machine thinks that there is no water getting to the machine. Majority of the time, this is caused by blockages of coffee in the brew group due to improper cleaning. I'm not saying that you haven't been cleaning it but that is usually the cause. How old is the machine? And has there been a cleaning tablet been put through it every day? Advise removing the brew group and check all pipes are clear, clean all loose coffee and check if you can blow through all of the pipes if you can loosen them. Clean coffee outlet/spout also. If the machines water is fed from a tank, It could also be a small bit of dirt has been pulled through. Hope this helps.
