My 301 panel got in contact with the some salt water.
The display is no more, everything else works. I can order the complete panel at SVB but maybe someone knows whether the display is available as a separat spare part? I had no luck googling.
It's likely to be a standard component, rather than a unique part for Bavaria. If you dismantle your panel to get at the display, it may have an identification number on it.
After more investigations I think it will be better to replace the panel. The salt water can do damage even at a later point in time. I'll let the insurance handle it and keep the original around as a spare part.
