    • Nivona CafeRomatica NICR 646 - Machine is dispalying pictograms, as if in some kind of test mode, can't go to making coffee

      Hersteller: Nivona | Typ-/Modell: CafeRomatica NICR 646 | ca. Baujahr: 2016

      Hi, I'm writing in English, because my knowledge of German language is limited - I can understand most of it (with the help of google) but am not able to describe my problem with my nivona 646 using it. I really hope that somoebody could help me with this issue.
      I've bought used Nivona 646 - seller claimed that it's broken and didn't want to repair it. It turned out, that after cleaing and insterting the brew group properly everything was working OK - I was able to make coffee.
      I made one cup of coffee and, as the espresso machine was really dirty inside, began to dismantle it and clean thoroughly inside. I also dismantled the front with the display and disconnected it from the electronic board which manages operations of the espresso machine. After putting it back together I can't make coffee - when I switch it on I can hear the brew unit motor operating and pcitograms on the dispaly are blinking - all of them light up and, by pressing buttons and turning the knobs i can change which icon is visible , but ca;t go into coffee-making mode. I guess it's some kind of test procedure, but how to quit it? or is it some other nmalfunction ?

      long story short - after taking espresso machine apart and cleaning it, icons on display are visible and I can swtich between them, but am not able to star making coffee.

      Hope you can help me with this issue.
