Jura Impressa S model backpanel

Stap 1

The backpanel is secured with two proprietary screws with oval head. They seem to be rivets, but in fact are screws. The only purpose is, to keep us out of our own devices. You can remove them using an oval drive bit. (Part of some IFixit tool collections or available at a Jura provider or iFixit). In a pitch try needle nose pliers. Here a DIY guide.
