Hi anybody know how to reset/ calibrate water level indicator in a 2007 Joint sl154. It shows the water tank as in reserve when it is actually full ?

Caravan/motorhome water contents gauges are notoriously rubbish and utterly useless after a few years.
They use a number of probes to detect the water level rather than a flaoat and potentiometer like a cars fuel gauge. They corrode and fail to do their job

Give up now or you will drive yourself crazy trying to get it to work properly!
