failures on circuit board

[Sea Angel1]

I have failures on the service panel/Circuit board of my Dufour 40 (2014).
Some switches do not close the contacts and some LED's do not lighten when the switch is closed.
The service panel is built in a Dufour 40E (built 2014). The panel is built in France or Germany. In those years Bavaria had a cooperation with Dufour.
Who can give me the supplier or mention me a repair shop in France or Germany too check the board and replace the switches. Probably the switches are supplied by Reichelt in Germany.
Dufour is just not reacting to the problem.

Picture of the circuit board and service panel will follow.

Another question is to find out who is the supplier of the water tap in the head. It is leaking by opening the upper valve and I want to replace it.

Aany ideas and Thanks

1) The switch panel was made by VDO but is probably not a standard part.

2) Are you sure it's not the fuses and breakers? There is one fuse missing, for the switch marked Refrigerateur. Some of the breakers appear to be tripped (red button out) but it's hard to tell from the photo. Did you try pushing the red buttons back in? (Replacement ATC-style circuit breakers are available inexpensively from many sources, or you can install fuses)

3) The switches themselves are made by Würth Elektronik (part number 471002268143) and, though they are soldered in place, can be swapped in by any capable electronics tech.

Those switches are simple toggle switches widely available.

You can replace the tap with something similar but not identical visit a big plumbers shop

Thanks for your ideas.
Jammer:
I checked the fuses, which are ok. The soldered pins directly right to the fuses i did shorten them and the electrial function were ok. So I have to replace them by an experienced electronic techn.
But thanks.
