The transformer can break, especially if water drips on it from above. You should definitely eliminate leaks at the heaters. A typical error is when the machine can be switched on, the solenoid valve clicks loudly several times, but the brew group does not move and then "Error 8" (brew group not positioning) appears in the display.
Note: In these instructions, the top and right covers are removed. This is not difficult and makes the repair easier. However, it is not absolutely necessary. You can also just remove the back and get started.

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.

Can i use 16.5 v transformer?
The right voltage ist 15 V. I don't know, what happens if you use 16.5 V. I personally would not dare to do so. Perhaps you can buy a used one, all transformers of Jura and many other brands use exact this model.
