De winterizing problem

[gbaglo]

I would expect that if there was residue on a sensor that it would show "full". Like when a piece of TP gets hung up on a sensor in the black tank ( shows full even though empty ).
But, your monitor is showing empty when full.
Another factor is that there are four sensors so I wouldn't think they could all be bad.
I'm leaning toward an issue with the monitor itself, not the wiring or sensors.

That could be accurate, the thing is that is was working just fine, only after de-winterizing I had this problem, but if is the System monitor it would be more easy to fix (I guess) since the sensors are all covered.

I will keep monitoring this thread, So far thank You all for Your efforts in helping with this problem, You are most kind.

Why would the sensors in the fresh water tank be affected by antifreeze? You do not put antifreeze in the tank to winterize, you empty/drain the tank and blow air in the lines to winterize?
I fali to see any connection between winterization and the sensors malfunction? You keep mentioning residue in the fresh water tank, there should not be any thing other than water.
Did you fill the fresh water tank with antifreeze?

Don't know what year and model your trailer is, so I can only guess where the monitor is located. Mine is on the cupboard, above the stove. I haven't looked, but, would it be possible for a wire to come off the monitor, inside the cupboard?

Actually, you can, and use the pump to pipe it through the lines, but there are better ways to do it.

[cpaharley2008]

That would take a lot of antifreeze, that is not the way it is supposed to be done.

Maybe fill your tank 1/2 full and go for a drive the shushing around may change things.

I agree.

I have another theory...
I assume that all three level "sensors" or electrodes (at 1/2, 2/3, and full levels) are read by checking for conductivity relative to the fourth electrode at the bottom. If only that one bottom electrode has a bad wiring connection, the indication would presumably be empty.

I would remove insulation as required to expose that bottom one, following the wiring.

[gbaglo]

Question is, how would the wiring go bad, being protected by the insulation from impact or whatever?
I was just looking at the picture of my sensors and I don't see any massive corrosion after 6 years.

Good point, but wires can break or get pulled off, and foam isn't necessarily good for preventing corrosion.

Of course checking the monitor at its inputs would isolate the problem to either the wiring&sensors, or the monitor... if one had the documentation to support testing properly, and access to the input terminals of the monitor.

Guessing is over, is one of the wires below the bench (Inside), Reace solved the puzzle,
The insulation actually traps the cables and help to keep them in place besides of protecting from corrosion.
And by the way the new instructions from Reace to winterize are the ones I followed putting antifreeze in the fresh water tank and then pump to fill the lines bypassing the water heater, You didn't receive them on Your e mail?
I followed those instructions point by point.

Thank You all for Your efforts. You are all most kind.

Another reason to have the E-Z winterizing set up option, the pump pumps 1 gallon antifreeze thru all your lines, nothing ever goes into your tanks.
