Water tank gauge on 330 express

Anybody know what activates the fresh water gauge in the head compartment?

The fresh water pressure switch on the DC switch panel activates the gauge. The sender is aft on top of the tank. Hope that helps.

Thanks! I‘ll start tracing the issue today. Nothing else to do with the country shut down.
