Fresh water tank alarm

[Bailey 15]

Hi, we have Bailey 625 and recently having trouble with the fresh water tank alarm.
It seems to have gone very sensitive, on our last day of camping we used to b able to leave 15% water init, now when we get to 30% the alarm goes off.
We thought it might b due to grass pitch and unsteady but home on drive still doing it.
Any thoughts please

Hi,
The metal straw like Sensors in the tank 'furr' up with scale a bit like inside a kettle and give an erroneous reading.
I had the opposite with My Burstner fresh water tank. It was full but an alarm sounded { usually in the middle of the night } telling Me that I was low on fresh water.
Carefully remove and clean the sensors inside the tank with a dish washing white sponge to remove the scale and refit the sensor and test.
Far cheaper than buying a new tank sensor.
It worked for Me.

Probably a calcium build up on the probe/probes, descale them with some white vinegar and it will probably work.

I am reliably informed they are extremely sensitive in the first place. If you take them out for cleaning, they can be recalibrated on refitting through the control panel. Never done it, I just switch the alarm off through the control panel and keep topping up with what We need for a few days
