apparently this isn't a theoretical "what-if" question, and you have some sort of issue?
If I'm reading correctly, it might be just that your tank sensors aren't working correctly. If that's all it is most folks just learn to live with it. They aren't really all that useful anyway. I'm the type of person that is bothered by something that doesn't work....so honestly I'd almost rather that the lights were never installed! Mine still work most of the time, at least sorta kinda....
I have had occasion when they didn't work right at all, and then after a did a couple rounds of fill and flush with clear water they seemed happy again.
OR....The wand through the toilet is really no big deal, and I have even dragged a hose through the door a few times just to fill the black tank with clear water faster.
Depending on your issue, you might try soaking it a few days with your chemical product, followed by drain, and then if you feel like there's still too much stuff refill with clear water and drain again...maybe repeat the clear water a time or two.
But really, it's a blackwater holding tank. No need to get it pristine!
