Hey guys, My water tank shows 0% full even when its full, no other indications. I also have the EPLEX system in my 2007 36DB. What part do you think has failed in this system? BTW waste system tank level indicator works fine...TIA Lance

Come on guys, where's the tank sensor specialists?? ;)
 
Have no experience with the water tank sensors, but I would think they are identical to the holding tank sensors. If so, either the floats are hung up or you have an electrical issue. I would start by pulling the probes and checking out the floats and then go electrical troubleshooting. Maybe an Eplex issue....

Another member here was generous enough to help me out with my tank gauge. He swapped out some transistors for me and it’s working perfectly now.
But my symptom wax it always read full no matter what the level was.
But, I remember looking at a 36 Sedan Bridge a few years back and it had the EPlex system. Rare bird indeed.
If your fresh water tank sensor is part of that system you may be better off touching base with other 36 Sedan Bridge owners to see what their experience has been.
