Fiat Tribute T669 Battery/Lights/Water/Waste control panel

Our otherwise perfect night at Drum Manor was slightly marred by our control panel playing silly buggers. when pressing the Water On button, on several occasions the button above (outside light) light up and turned the outside light on instead. The Waste Tank alarm started to spontaneously beep to let us know it was 100% full when we were absolutely sure it was not even a third full. We assumed the waste water sensor had maybe frozen (the skylight had frost on it), so hubby had a look as best he could. He couldn't see anything frozen and he drained the waste water tank. Again, it bleeped spontaneously at 100% full, even though completely empty. The Water On switch also did a 'double press' when it was depressed just once, like a very quick on/off but just with one press. We wondered whether it was the low temperature - the gas ran out during the night so it was a bit baltic inside (although we were snug under the duvet and the Kerry wool blanket!). By the time we got home, it seemed to be working normally again.
I need to dig out the owner's manual from wherever hubby has hidden it, but neither of us remember any control panel manual. There is no manufacturer's name on the panel and even I, the queen of Googling, can't find our model on t'interweb, although I did come across a few posts which suggested that these panels can have a bit of a meltdown now and again and need a quick reset, the only problem being that we don't know how to do this on ours.
Just wondering if anybody has had similar experiences before we bring the van back to the dealer (still under it's warranty, thankfully).
Many thanks in advance.

Thanks, Mark and Wendy! We've made it home but we'll play around with it in the next day or two to see how it's behaving and, if needs be, we'll give your leisure battery tip a go. Enjoy the rest of your weekend, and thanks again!

Sometimes when electric panels or circuit boards go on the blind and turning them off doesn't work, disconnect the leads on the leisure battery for a few minutes. Sometimes when the power is totally removed and then reconnected the electronics reboot themselves into working order.
Sometimes the cold mades the electronics go wonky.

Just another thing to check. The earth strap on the leisure battery, check firstly the battery pole and then the connection to the chassis or the floorpan. If this spot is rusty, the 12 volt power supply will be affected. Chassis earth connections are prone to fail at this time of the year due to salted roads causing corrosion.
Happy hunting,
Malcolm

An education being had here! Where would we (I mean hubby) find the relevant earth connections? I know a bit about where mechanical/engine bits are on a vehicle, but not so good on electrics! I wonder is it best to drop into the dealer as it's still under warranty.

If it's still under warranty then drop it back to the dealer. You might end up doing that anyway, and if he discovers that someone else has been having a go at repairs he could walk away from the warranty.

Hi

I still belong to the Tribby Forum and quite a few members have your van

If you copy and paste your first note and request for info on the control panel someone might be able to assist
