I've flushed the tank using the built in black water flush. Any other ideas? I'm in for the season so driving around with ice cubes in the tank is out.
Some folks swear by it, but I'm dubious about the ice cube method. The problem with the factory black flush is that if it's not spraying directly on the sensors (unlikely, and difficult to verify) it's not going to help de-crud a crudded up sensor.
If I were in your shoes I'd put plenty of detergent and water softener in the tank, fill it up with water, and let it soak - preferably overnight. Since you can't rely on your sensors to "fill it up" you can stand on the flush pedal while peering down into the abyss with a flashlight to watch the level.
Then I'd dump the tank and attack it from above with a wand, working your way down slowly and turning it 360 degrees to make sure every inch of tank wall gets sprayed. Again, the problem may be that if the down-tube from the toilet protrudes too far into the tank you simply may not be able to direct the spray on the offending sensor.
I was young and na´ve when I bought my first camper (three years ago - I was 59) and didn't take proper care from the start, ending up with Mount Poopmore in the bottom of the tank, greatly reducing its effective volume. It took a lot of yucky attacks with the spray wand to fix that... at which point I discovered the GEO method and had no more problems. Started GEO with the new camper on day one... and I believe that's the trick - never getting into a bad situation to begin with. Not a criticism - I was there myself - but doing what I described in my previous post from the start will prevent a bad situation from developing in the first place.
