Fresh Water 0% full

Yes, our display thinks the fresh water tank is empty despite there not being any room in the tank. And because the display thinks it's empty the pump doesn't want to turn on consistantly.

Obviously this will turn in to another warranty claim but in the meantime are there any fixes? We have 3 nights on sites where we can get fresh water and not bother about using the tank but then we go to a sports event and would like to use our own facilities.

Remove panel and do a reset ??  I know nothing about Sargent panels but I think I've heard of this before on the forum.

I will go along with Paul's suggestion

Me too.

I think I have the instructions for how to do it somewhere. Do you need them (before I start hunting them down!  )

Not sure. I have the 6" pile of books that came with the van so I'll start looking.

Thanks for the answers guys. I'll let you know later.

I don't have the tools to do a "remove panel and reset" but the book says the panel can be rebooted by turning the PSU off for 30 seconds. I still have 0% water the pump is now happy to shift it.

So to reveal ignorance but just in case other Forum members also don't know, what's the " PSU", please?

Cymro, a PSU is the power supply unit.

regards Leighton.

PSU = power supply unit.

I turned off the main switch inside the cupboard but I can't see there being any difference between that and plugging the van in. Currently my display is scrolling through 25%, 50%, 75% but at least we have pumped hot water. We will find out tomorrow in Bavarian electricity gives the same result as Luxembourgish electricity.

after reading the instructions and listening more carefully, the pump DOES work when the panel is complaining about 0% fresh water. It will show 0% some time after the 25% mark has been reached rather than waiting for an empty tank and the alarm can be turned off by hitting the sideways arrow key.

We will be back to Marquis on our return but for now we are OK.

Morning Dave

Hope I'm not telling Grandpa how to such eggs!  

Think of filling up the tank from empty . . . . .

It will show 0% all the way from empty to 24% - in theory anyway . When the water reaches the sensor peg it will show 25%, but that should be interpreted as "at least 25% - probably more".

This is because it will continue to show 25% until the tank is actually 49% full. A drop more water will take the level high enough to hit the 50% sensor peg, and it will then show 50% on the screen. Again this should be interpreted as "at least 50% - probably more", because the display won't change until the water level rises high enough to touch the 75% sensor peg.

It's a fairly crude system, but anything more sophisticated would be considerably more expensive, so we ain't going to get that, are we!! 

Enjoy your holiday, whatever!!

Thanks Dave, I was aware but my last post was as much for future refence so your explanation sits there nicely.

Holiday is going well, currently sitting in the Bavarian sun eating home made sandwiches.

Yes total pain
Fresh water beeps all night with 25 % full
Waste water beeps and indicates full when empty...surely there must be a better system.. Clearly the digital facility is failing

It's a pity they can't design in the infallible system of a clear indicator tube. I had one for the cistern on my Clubman - simple and clear. Like my central heating oil tank before they put in an unreliable and annoying wireless transmitter!

If the facility of indicator tubes for the 2 water tanks and the cistern were to be borne in mind at the design stage, it might be possible to incorporate them - at surely less cost (and hassle) than the electronic ones which are not very good.
