Monitor Panel reading false

[BessieB]

So I hit the road last week for a few days. Didn't have to fill the water tank, my monitor said full, KOOL!!!!! Not. It started sucking air after our well deserved showers and when it came time to do dinner dishes, we were sucking air. Monitor still said the water tank was full.

Anyway, came home dumped the tanks and the monitor shows full water and the black and grey tanks showing yellow. Now with that combo, I would say the panel is wrong and not suspect the sensors.

So searching these threads is not user helpful. So I am sure someone has a link to trouble shooting the monitor? Looks like my 97 Excella is a Philips? Circuit board replacement? So I need guidance as to where the circuit board is and all the dummy details.
Thanx........

It may just be a loose or corroded wire. Check the wires to the sensors, then check power and ground wires to the monitor.

BTW, it's not reading false, it's displaying alternate facts...
