I'm not familiar with your specific model, but the tank rinse function lets you spray fresh water into the waste tanks to help flush them out after dumping the contents. Rinsing (flushing) is a precautionary measure - think of it as preventive maintenance. You can and should flush away any remaining crud when & if you have time and plenty of fresh water available.
Some RV have both black & gray tank rinses, while others have black only. If there are rinsers in both tanks, there is probably just a single inlet port (hose connection) and a valve to select which waste tank will be rinsed (flushed)

We have one for the black tank. I use it whenever we're at a park with hookups. It either doesn't reach the top two sensors or the previous owner didn't rinse adequately. When I check the tank level after rinsing, the first two show empty and the top two, meaning 3/4 and full, light up indicating they are still full. Suspect some hardened waste on the top two sensors. Either the previous owner didn't rinse enough or the spray does not reach the top.
Suggest you spray frequently to keep them clean.

It's a fleetwood motorhome but I have no idea what system is used. Immediately after I rinse the black tank it shows empty at the quarter and half levels. The 3/4 and full have always registered full. However, within an hour or less of rinsing, the quarter and half level lights are lit. I have a through the toilet spinning device that I plan on trying. We'll see what happens.

Welcome to the forum. You must be a newbie at RV'ing. One thing when it comes to black tanks and is very important. Always leave the drain valve closed while camping. Let the tank fill up to at least 3/4 full before you dump. Add water if need be. This will give you a good flush of all the solids. It won't get all the solids but then you can use your flusher. The gray tanks drains can be left open while hooked up to a sewer system. Some will say don't leave them open. You'll just have to try it either way.

Just be careful when you use the through the toilet tank spinner that you are wearing old clothes and have removed the nice towels and rug. You have to open the toilet valve to put it down the toilet, which means it may end up spinning and spraying a lot of gook up through the open valve.
Maybe cover the toilet with an old towel while you do it??

Since it hasn't yet been mentioned, and you may find it useful, here's the dump/flush procedure I use. We do have a built-in flush connection.
By the way, this takes place at either a full hook up site, or a dump station with flush water (and not a big line of others waiting).
1. Connect sewer hose to coach, install clear elbow on hose, insert hose into sewer pipe. (Definitely get a clear elbow. It's invaluable to see what's going on as you dump.)
2. Connect flush water hose to inlet fitting. (DO NOT use your drinking water hose for this!!)
3. Pull black tank dump valve, wait until flow of waste stops.
4. Turn on flush water. Takes a moment to begin draining - you'll see it happen at the clear elbow.
5. Let it flow until the exiting water starts to become clear. This could take a moment. You'll be surprised how much "stuff" still comes out at this step.
6. With flush water still running, close dump valve and let it fill for a few minutes. (CAUTION - DO NOT leave it unattended during this step, and be sure you aren't letting it fill long enough to get the tank too full. This step is just to loosen up any remaining waste.
7. Turn off flush water, re-open black dump valve.
8. When flow stops, close black and open gray.
9. When gray stops, close dump valve, disconnect hoses. You're done!
Usually takes me less than 10 minutes.
