Hello, I have purchased Jura Impressa F9 about 4 years ago and have been using it a couple times daily since that time. Some time ago, I have started having problems with brewing coffee on each program. The coffee wont go through coffee spout, the machine shows that the coffee is being made but nothing comes out of the spout. sometimes it does make the coffee but then the program wont turn off and it says Malfunction 8.Can you please tell me what is wrong, thanks.

Machine is most likely clogged with old coffee grounds and needs a good cleaning cycle malf 8 is problem with the stoke of the piston can not make a complete cycle thur get your book out for machine and read list for cleaning machine follow remove power cord for a few mins. let machine cool down if hot from prior use then plug back in power up and do cleanning cycle with tablet follow book worst case would be oring seals on piston are no good or very dry making machine work to hard to move piston in this case service is needed good luck steve
