Anybody have an answer for this problem? It's so plugged that no flushing water can get through.

The nozzle is easy to remove and it is simple to unplug when removed.
Follow the water supply to the unit. If you can't find it call CC, they will tell you where it is. On my coach it was just to the right and above the flushing water supply.

Good Luck,
Paul S.

I'll bet the problem is all the liquid has been removed from the tank. If your coach is equipped with a back-flush valve, connect a water hose to it and fill the black water tank about a 1/4 to 1/2 full. You could also add some microbes to the tank to eat on the solids. Then you need to drive the coach around to mix it all up.
To prevent this from happening in the future, ensure the tank flush valve is closed securely. Do not leave it open when you are camping. Also keep the microbe level up to help brake down the solids.

If you don't have a back-flush valve, try adding water to the tank through the toilet, via a hose. Be careful not to damage the seal on the flapper.
Hope this helps.

In general this happens because there has not been enough water introduced to the tank prior to dumping. A couple of general hints:

1. Always add 3-5 gallons of fresh water after dumping. This is easy to do by just leaving the flush hose running for a minute or so after closing the black tank valve.

2. Never try to dump the black tank unless it is at least 1/2 to 3/4 full.
Add water if necessary to bring it up to this minimum level.

3. Add a little water during accumulation by occasionally running some additional water into the bowl after usage.

4. If it does clog up just keep running the flush hose to add water. It
will often "turn loose" once enough water gets in the tank.

flushing water can get through.
I'm not sure if you mean you can't flush the toilet or if you can't use the flush connector that allows you to spray-clean the tank (if you have such a tank.)

If the toilet can't be flushed:

Use a roto-rooter tool. Costs about 10 bucks at stores like Home Depot. Once you feel resistance, turn the snake and try to pull up as much of the debris as you can rather than continue to turn the snake and, thereby, shred the debris with the snake it falls into the tank.

If the toilet is stopped up like that, someone may have tried to push something down that doesn't belong in am RV tank.

If the spray-clean inlet is stopped up: This may no longer work when the problem is as severe as it seems to be in your case but worth a try:
1) Empty tank.
2) Fill with water (flush) to 1/8 of capacity or less.
3) Buy a large bag of ice and flush it down.
4) Drive coach.

The ice will knock "debris" off the walls as the water sloshes around in the tank while you drive. Go on a tour, not just once around the block. Over time, the ice will melt.
5) Empty tank.

I would be hesitant to pour any chemical solutions into the tank as it may destroy the seals and maybe even the pipes and tank themselves.

I hope this helps.

I had that problem and fixed it myself. The no-fuss flush nozzle in my Intrigue is on the tank right side accessable by removing the panel in the right side bay just in front of the rear axle. In my case, it looked like it was plugged with debris probably left from the assembly. The only way to clean mine was to remove it and clean out areound the many very small holes in the nozzle. The most difficult part was removing the fibreglass panel inside the bay covering access to the holding tanks.
Just got back from month trip to Oregon and was offline until this morning.
