The flush has suddenly stopped on my Thetford caravan toilet, I would like to replace either a fuse or the motor.
Anyone any idea where the fuse is??? Have unscrewed the dummy top part & there is a screw inside but not sure if this is the correct place.
Please help

if you look in where you waste barrel is . remove it and look on the top you will see a black round fuse casing unscrew and replace

Ironically, I am working on my Thetford C2 toilet. The fuse in mine is a 3 amp small glass cylinder style that I found at Radio Shack. The instruction manual, however, shows it as a two-prong automotive fuse. At any rate, to get to it, remove the waste tank and on the middle left of the underside of the upper portion of the remaining top part of the toilet is a switch cover (# 29 in the Thetford diagram) which must be turned 1/4 turn to the right in order to see the small black circular fuse cover. Unscrew the cover and the fuse comes out with it.
I replaced my fuse and the toilet still won't pump, so I'm trying to narrow it down from the pump motor, switch or wiring to either one.

In my caravan the fuse is fitted in the mechanics of the handle which controls the opening of the lid on the cassette. Take out the cassette and look in the roof of the small compartment, there you will se it.
