    What is the most USUAL reason for the control panel saying there is 100% water in the tank when you know for a fact that there isn't, please?

    My theory is that until the water level drops to the next sensor the reading doesn't change.
    The other problem is that the position of the sensors may be incorrect.
    If the MH is not level this will affect reading.
    Water level indicators are renouned for being inaccurate.

    We very rarely take any notice of the readout. They are generally wrong :(

    we cant ever get ours to show 100%, even when it has overflowed back out of the filler pipe best we get is 75%

    but do you still have 100% even when completely empty?

    That could be because your float is stuck up :D

    I thought I was daft ................. then I read most of your answers and realised it was you lot....:) Thanks all for your responses... Yep. think it cos my van not quite level, or that my sticker up is stuck up.. or the panel not accurate, which I can cope with.

    Don't think my van is upside down but one never knows these days... could be the clever manufacturers put the wheels on top of the van instead of the bottom ....

    You never know..............

    Most of these gauges are hopelessly inaccurate and a rough guide at best. Cheers!

    Ours always says it's full till it's got about enough to wash up a couple of times then it jumps to empty, don't really take much notice of it and fill up whenever we see free water thingy

    What we want is SOLUTIONS! It's no good all of us saying they're unreliable.

    The one on my previous old van was spot-on. So I spend zillions on a new 'van and as soon as you put a cupfull of water in it, the needle goes past the full to end-stop! It's not something you can check at the dealership and I can't 'dip' the tank because it's under-floor.

    I'm cheesed off with it. It's not just a question of having to leave the dishes till the morning. For me, a lack of water means no toilet flush either!

    On my last sortie a few days ago, I had to fill up until it overflowed, then open the drain cock and drain off bucket loads of water until I thought I had the right level for the journey:mad:. I rarely travel with a full tank, coz for me (with a 70 litre tank) it's over 150 pounds in weight!

    It ain't good enough!

    But there are usually sensors only at 25%, 50% and 75% as well as allegedly full and allegedly empty. The manufacturers have to strike a balance between what most people will be happy with and the costs associated with an accurate system, which most people don't think you need anyway........... Most of us don't need a solution, really.

    To be honest, I did check out the system readouts on the Pilote and it is surprisingly close. Works for us! (y)

    The sensor rods get 'furred up' with salts and need cleaning, cloth with a dab of Vinegar usually does the trick

    there is a difference between ideal technology that works correctly and a simple system that+ is cheap and easy to fit. most vans have the cheap version...... a set of brass pins stuck through the side of the tank. as the water level goes up, it covers the pins in sequence making an electrical circuit. simple and effective till the pins corrode

    if the gauge constantly says full, its likely a short circuit on the wires on a basic system and a stuck float in a more expensive one
