Water sensor - any way to bypass?

[DaveHobson]

On a 2018 Bailey Advance, the water level sensor indicates 0, however full the tank is. This has the effect of disabling the pump. I know how to force the pump to run, by pressing and holding the pump switch, and I have gone through the process of recalibrating the sensor, thanks to a post on here (thanks), but still no joy. So it seems that the sensor is knackered. What I’d like to do is to just override it, as we’re part-way through a France trip without much hope of being able to replace it. Any ideas?

Without pictures I can't say for certain.. But many level detectors used the water level to complete a circuit. So if you can access the wires to a sensor and join them together it will always think it is full

Well, we have progress. When checking the connections for the sensor, I disconnected it (just by unclipping the 3-wire connector), and the pump started working, so it seems that that is the way to bypass it. Of course this leaves us with no way of knowing how much water we have, but a simple dipstick through the hole where the sensor tube usually goes gives us a pretty clear indication (probably more accurate than the gauge itself?!). I hope I’m doing no harm by running the pump without the sensor, but can’t see that’s a problem?

One other detail, possibly relevant, possibly coincidental - it seems that the grey water sensor is also showing 0%. Not sure how long that’s been the case, as we tend not to look at it - just empty the waste whenever we move on.

These are worth looking at

Water not coming out of tap...empty.....water coming out of tap...enough...

Just don’t run the pump without water in take or that may damage it.

Does anyone know whether the pump override function i.e. keeping finger on the pump switch works on a 2012 Approach? Tried it when emptying for the winter. Wanted the pump to drain out as much water as possible. Didn’t work for us.

Incidentally, have never found where the sensor in the fresh water tank is. Have reached in and felt all round but not found the sensor. Must be one because there is a readout when filling and as one uses the water.

Can’t answer your question but, just in case it helps, on our Autograph 68-2 it annoyed me that opening the water tank drain valve left over 10% of the contents still remaining.
I unscrewed the tank access lid to see if I could modify the pipework and noticed a red plastic bung on a chain in the base of the tank I’d not seen before. Removing this allowed the tank to empty completely.
Don’t know if you have the same feature (which I’d not seen mentioned in the handbook) but it certainly makes winter drain-down much easier.

On my Autograph, the sensor wire had broken at the connector. Corroded due to sitting in water on top of the tank.
Just crimped some links on and job done.
