Thetford C260 fuse location

I cant help with fuse location, but are you sure this is the cause of the problem.

My toilet refused to flush on a couple of occasions after standing a few weks, and it was the pump impeller that had stuck. To get to it, you have to peel back the top cover where the flush button is.

I believe you can also have problems with the circuit board below the flush button.

Thanks for replying. No I don't know whether it's fuse but was going to start with that. How do I know if the pump impeller has stuck? I did see a you tube video showing you how to get pump out.

I do have a caravan repair man that can look at it. 

Just a little tip Myra, put the bathroom light on and press the flush button if the impeller is just stuck the light would dim a little,also in some cassette cupboards there's a fuse in a holder at the rear base behind the tank.

Thank you for your help. I will try this.

If the impeller is stuck, it just needs a little 'help' with a screwdriver usually to free it. If you peel the label back gently, then it re-attaches easily, without needing a new one. Mines been opened 3 times and still OK.

Thank you.

This fixed my issue, thanks. Carefully eased the cover around the switch and 2 screws to remove the part that the pump hangs from. Gave the impeller a turn and it worked fine. Also helped by the comment about pushing flush button to see if the lights dim, indicating the power was being called by the switch. 

Mine is C262 model stopped flushing. The fuse is in the main 12volt fuses under Sprite caravan seat but that was ok.

It turned out to be the tiny pump in the cistern was seized and just needed a spin with pointed tool. I accessed the pump by peeling back the label on the flush switch and prising out the switch assembly. Then remove the 2 screws and pull up the pipes with the pump on the end.

Surprising how much scale and bits had accumulated in the pump impeller.
