Hi ,I have a red light appear on my toilet unit (inside the toilet cubicle) , Im assuming its telling me my toilet is full , but its not , the light goes off when I remove the cassette , Am I right in assuming that the sensor board inside the cassette compartment is faulty ? or would it be something in the cassette ? , Im not really bothered about the light , but I cant use the flush , also How to I find out what thetford I have ?? , I cant see any info anywhere , Ive found a board on Amazon , but it looks different to mine , are all sensor boards compatible with all toilet
Simple answer!
There is a white plastic float inside the cassette that has jammed in the "up" position.
Remove the cassette and open the top hole. Either with a gloved hand or a screwdriver simply tap the float and it should drop down. Ensure there is no paper (or anything else) stuck around it and job done.
Before replacing the cassette make sure that the top 'door' is fully closed.
Good luck, DaveS1
To answer second question: the model number is usually shown on the underneath of the cassette. If not, look at www.leisureshopdirect website where they have exploded views of most things. Yes, there are different little circuit boards and they do sometimes suffer from damp and pack up.

Yes, I think DaveS1 has it spot on. If the sensor board, (little more than a reed switch) was faulty, it would make no difference whether the cassette was in or out.

Thank you all
I think it's the circuit board because the toilet was working last time we used the van . And we never let the cassette fill up. So I font think the float would be up the top . But will check . I think I've found a new board with the same board number ie 50569 even though it looks different it has the same board number . Do should fit surely?
Update >> Yes the Float was stuck up , freed it and float working fine , Thank you for that info , no paper in there as we never put paper in the cassette , checked in side , red light gone out , however >> toilet still not flushing , so will order a new sensor , also found out from a kind replier to my post , I have a 250 toilet :-) thank you all for your help ,
You perhaps don't let the cassette fill up but that doesn't make any difference really because when you withdraw and remove the tank, the contents and liquid tip to the end of the tank due to gravity. That movement could cause toilet paper to jam between the plastic float and the tank side wall as mentioned above by DaveS1. If the float has jammed then this could possibly activate the red light (tank full) as the position of the float dictates the warning light but not in any way is it fool proof.
As well is two words!
How does a sage know everything about everything? or does he? or does he just think he does?
Remember, if you buy something you bought it, not brought it.
The tank full warning light is just a 'dumb' indicator light, it has no interlock or control over the flush, so you should be able to carry on flushing even when tank indicated full! If you can no longer flush, that's a DIFFERENT problem!
The solutions already given about freeing the float within the tank are spot on, it's quite a common problem! You don't have to fill the tank to cause a jammed float, the float is effectively at the bottom of the tank when you carry it by the handle to empty, so 'debris' can jam it then! Over vigorous 'shaking' of tank when rinsing out after emptying can also cause float to jam, even become dislodged! If the light goes out when the tank removed, then it's a pretty good sign that the circuit boards are OK and replacement NOT necessary.
BTW, Thetfords idea of full (when the light comes on) and a truly full to the brim tank (when you peer down the hole to judge!) differ by a 'use or two'! - wise to heed the warning light though, but there will still be space above contents level if judging by eye (you REALLY do not want an overfull/overflowing tank!!!! - horrible mucky process to rectify, and it WILL spill INSIDE your van bathroom!).
Pumps sometimes get 'sticky', especially after a period of being unused, and the rotor won't spin (wont pump!). Easy to diagnose, turn on the bathroom light, press the flush button and a 'stuck rotor' will cause the lights to dim slightly (as does normal function of the pump, but without the whirring noise)! If the lights don't dim, then it could be the switch, circuit board, connectors, or pump gone faulty. Stuck rotors can sometimes be freed by repeated pushes of the flush button to jolt it back to life, but DON'T hold the button on for a prolonged time, you risk burning out components as the motor draws quite a high current!
If diagnosed as a stuck rotor that wont free itself, taking the pump out and gently tweaking the rotor blades to rotate a bit with a thin bladed screwdriver or the like that can reach them, often brings the pump back to life. The whole process is too long winded to describe here, but several Youtube videos show the process pretty well.
I thought it would spill in to the cassette compartment, NOT the bathroom floor.
------------- XVI yes?

My understanding of an overfilled toilet waste tank, is that the overfill stays in the toilet bowl. If you then try to remove the waste tank, the overfill will flood the tank compartment. Nasty.
I believe the waste tank is designed such that the spout for emptying the waste tank, is in a section of tank slightly lower than the top. This should make it possible to rotate the spout to point out of the compartment, hold a bucket beneath it and remove the screw cap (gloved hand recommended ). That should allow sufficient of the overfill to run into the bucket to make it dafe to remove the tank for normal emptying.
Never been in this situation, so no personal experience, but got to be worth a try if you are ever caught in that predicament.

.... it does initially and to a degree, but the cassette compartment is above the bathroom floor and not sealed in any way, so what's in the compartment can leak into interior and the floor, it's NOT really contained! Evidence of that when I first got my van, and previous owners must have had a problem!
Ancient Uncle's explanation of draining an overfull tank through outlet spout makes sense, although seemingly an undocumented feature. Racking my brains to recall exact post from a few years back now, but someone, and supported by others IIRC, flooded their bathroom when dealing with an overfull tank that had backed up into the bowl! Tales of needing to bale out, suction pumps etc. to lower bowl level sufficient to avoid flooding! What many didn't grasp was that the flap and seal were part of the cassette, NOT the bowl, so removing the cassette with contents still in bowl was a BAD idea!
Hi , after a long battle , I have now found out it was the pump , I have replaced the pump and the flush is working , Hoorraaayyyy , however >>> I now have a leak dripping down from the pumps housing , I believe it to be coming from the Vacuum Breaker ??? , is this gadget attached to anything ?? aprt from the 2 pipes that are pushed on the bottom of it , it came down when i removed the pump , it does have what looks like a clip type thing on the side , but apart from just pushing it up the housing I cant see how to attach it ???? or where to attach it
