Tank monitor display quit working

[homer1959]

Hello guys,any idea when we returned to the trailer tonight the wife noticed that I have one light lit on the tank monitor the one indicating Empty however none of the button works. Battery ok, water heater pump etc etc works , only the tanks level and battery charging condition dont work .The push button if you prefer

I opened the box and disconnected the elect. board wait for a minute for it to reset, plug again same problem one light on nothing else works , ground in tank wiring maybe ?
thanks for you suggestion

Welcome to the "Idiot lights don't work any longer" club (no offence intended, 60's term) . Ours became inaccurate within the first 6 months (4+ years ago) and died a little after that. The sensors in the tanks get coated and stop working. Actually they don't stop working, with the coating on them, they do not sense the water. As for the battery monitor, it is about as useful as the thank monitors.. so do not depend on that one either.

There is an outside chance that the connections on the back of the display/switches may have come off. You can remove the display and check the connections.

There are kits to change them to a "Capacitive" sensor$$$$ but we just empty them every few days.

Do you have an open underbelly on your WH?

If so, I would crawl under the unit and check the wire connections at the tank sensors. When we bought HTT, the wires where hanging down and could easily be damaged by road debris. I pulled them up and sealed the connections with liquid electrical tape (messy stuff).

Mustang, I am fully aware that the sensor arent reliable however they worked unreliably before... ;-) and now nothing on all tank or batt.all I can get is an E when I press any button.

Jagiven, enclose belly on my WH, anyway the tt is still under warranty so the dealer will have to deal whit that one thanks guys

That's exactly what the problem was with mine also

I have (I should say had) an enclosed underside on our 145RB slx baja edition. I was forced to remove the Plasti-core liner due to rodent infestation. Poor quality installation left more than a dozen entry points between the usual vapor barrier and the plasti-core liner, along with the unseen and inaccessable plumbing and wiring poke thoughs from the interior of the TT. Thus creating a full length rodent hotel between the plasic-core liner, the vapor barrier and the flake board floor panels. "All", repeat, all wires to the tank/battery sensors were chewed apart by the offending rodents. It was necessary for me to completely re-wire the tank/battery sensor wires because the factory terminal connectors at the tank connections were left with too little wire length for crimp-on repair connectors, so all new wire and connectors were required.The "idiot lights all worked, but only sensed the low setting for tanks due to lack of a completed circuit.
As previously stated the lights are unreliable,but don't work at all if chewed apart by rodents.
