Fresh water tank not giving a level help?

Hi guys i have a 2015 bailey 540. My fresh water tank has stoped giving a reading. I have tried re calibrating it with no joy. Is there any other way i can test the sensor before buying a new one?

Common problem as the gauges are often unreliable. If you have an access to the freshwater tank open it and have a look/feel of the electrodes in there - they may have calcareous deposits on them which can usually be cleaned off using a mildly abrasive scrubbing sponge (the ones with a white scrubber, not the more abrasive green ones) if that does not remove it, try wiping it over with a cloth soaked in vinegar (not malt vinegar as it is too strongly flavoured).

If those measures do not work it may be worth disconnecting the 12v supply and all connections to the control unit - so that resets the whole system. On our Sargent system that means removing it from the fascia and disconnecting the single plug and leave it out for 1 minute, that resets the whole lot on reconnecting.

If all of those measures fail, you may have to bite the bullet and either try a new sensor, or take it to an agent for checking.

Good luck, I hope that gives you some ideas, do let us know how things pan out, by the way, welcome to the forum.

Thinking of ALL the front line staff working to try to help others;Doctors, nurses, paramedics, cleaners, NA's, catering staff, support services and all others. Their work is appreciated more than you can ever realise-keep strong and safe.

Any typo that I make means the errorists win.

Remember Jo Cox and what she stood for.

Any comments above are only MY OPINION and should be read as that.

Unfortunately mine is a different kind. Its got one single what looks like a straw coming from it in a plastic tube to keep it ridged. Have removed it and gave it a good clean. No joy.
