Bavaria 39 cruiser Waste tank level

[osso63]

Hi, the waste tank indicator of my 39 cruiser are always blinking even if the tank are empty.
I already tried to change the sensor without success, also if i disconnect the sensors at all the led still blinking so, i need definitively the Circuit diagram of the ESW panel 201. Is there someone who can help me ?
I'm available also to pay the document if necessary.

Thank you

Hi,
You can find ce diagram circuit of the 302 Panel in the download section of this forum.

I had the same issue with my waste tank sensor, but after cleaning the sensor with vinegar, it was ok.

You can check the wire from the sensor to the panel to be sure that it is not broken.
