HELP!!! Cassette potty won't flush!

Oh goodness!

We have been learning about our amazing camper for over a year now and think we know her for the most part all the way!

Two weeks ago we dewinterized her and the only problem we have now run into is that our cassette potty will NOT flush. I have done extensive reading and can not figure out why it won't flush! Ugh...

We have a Thetford Cassette C-402 potty.

1. The water tank is COMPLETELY full - there is well over 2 gallons in there I believe!
2. The fuse (3 amp I think) WAS blown (how I don't know) so we replaced that.
3. The water pump IS on.
4. We will move the lever so the door is out of the way for waste to go into the cassette and then we press the button and no water runs.

HELP!? Ideas? What are we missing?

(x-posted)

I should add that we are continuing to blow fuses - we have gone through an entire pack of them!
We are disconnecting all power sources before changing the fuse - we put a new one in - reconnect all our power sources and it still won't flush...

Ideas?
  • Thanks Dakota98!

    We found a YouTube video and guess what - our potty is working!!!

    It was the impeller that was seized up - go figure!
