Heloo everybody. I have a problem with water tank sense on the new 505. On the panel they are always empty 0%. The disel tanks are ok, they are showing good. The electrician came on board and tested the sensors, they are showing good measurments. The sensors are analog. He also tested measurments on the small connectors which are going into the panel hose, and everything was ok. He also disconnected the water tank sensors jacks and plugged them in the disel tank sense on the panel, and the reading on the panel for diesel tanks (with water sensors now) was accurate. But when he plugged in the diesel sensor jacks into the water sense jacks on the panel, panel was showing 0% again! He told me that probabbly the inputs on the panel are dead because everything works ok except that the panel doesn't reed water inputs at all. I agreed with him. But, new panel came, and I have the same problem! Can anybody help? What could be the problem?

The problem is the crappy camping car sensor Hanse fits to the freshwater tanks. They are unreliable and fail suddenly, especially when you use some silveriodid additives to Keep your water fresh. The best is to replace it with a magnetic sensor from Philippi or Wema.

But why are they showing good when we unplugged it from water tank jack at the back of the wurth panel and plugged them in diesel tank jacks? Doesn't make sense. They are showing good measurments, if they didn't work as they should they wouldn't show anything when plugged into the diesel tank sense jacks? The common problem is that they are not showing good measurment at the panel, but my doesn't show anything in the water tank ever. The diesel sensors also work good until I connect them to water tank sense jack in the wurth panel.
