Thetford Cassette C262 Toilet Intermittent problems

[John-Boy]

Hi all first timer on here can anyone guide me through this as I've tried all the usual stuff - basically I have a Bailey Pegasus II Rimini 2012. The flush system works intermittently. I've checked the circuit board after checking the pump by using a 12 volt tester the pump whizzed so that was working I then put it back and pressed the circuit board an d it worked to my surprise but putting the thing back together it didn't work and now there is a continuous red neon light remains permanently on located on the left side of the circuit board not the red neon light to say the cassette is full in fact that stopped working some while ago I couldn't find a fuse inside but on removing a plastic cover where the cassette is housed I found another circuit board which I can't find anywhere on you tube the only thing I can think of is the pump has seized and creating a electrical circuit but I've no idea really as I'm not a electrician can anyone help please many thanks John-Boy sorry for the long winded version lol

Welcome to the forum.

Can only advise on my experience.
The printed circuit you found behind the toilet cassette is the reed switch, that controls the toilet full light, along with a floating magnet inside the cassette , Always corrodes. renew that, not that expensive
You may find a 3amp fuse near by, renew that and clean every thing , You say the pcb and the pump work then, you should be ok.
Clean everything until you can almost see your face. in it.

that's what my wife Pauline said (thats very strange love) lol then she said leave it loose so we can use it but thats not fixing the issue love

I wonder if there is a wire that is broken, when refitted but breaks the circuit when you refit the unit. Another hands on job to diagnose.

could be dude but if it is its in a place where I can't get at it without taking the whole system apart again

if you cannot sort it might be worth getting a AWS mobile caravan engineer to have a look at it
