Toilet full light!

I have to admit, I have not investigated this further, but it occurred to me while reading the other cassette toilet problem.

My little red 'toilet full light' seems to have a mind of its own - not that it's a major problem - a quick look down the hole reveals the current state of play.

Sometimes my little red light doesn't come on when the cassette is full.  This happened last week.  I emptied the cassette and when I put the cassette back in, the light came on with the cassette empty.  A wee strange (see what I did there).  It seems to have a will of its own.

Any ideas folks?

    We had problems with the toilet suddenly deciding to flush of its own accord, and it turned out to be moisture in the compartment which houses the printed circuit board (PCB). This is accessed by peeling off the sticky-backed cover with the push button on it. We replaced the PCB and also squirted sealant round both the small 'hatch' inside the compartment and also the wires which come through a rubber grommet. We were also advised not to overfill the flush tank, especially when travelling. 

    So far, so good.

    I had the phantom flusher too!  Dealer fixed it several times then the cassette leaked "my fault" except they didn't notice the two plastic halves had come adrift!  Fast forward to mobile fitter and no further probes except I do travel with the flush tank empty or almost empty now!  No warning light though for several years!

    I think that the toilet full light is lit by a magnetic reed switch which is in the cassette locker. This switch is energised by a magnet in the cassette responding to the fluid level within. Maybe your reed switch is sticking? I have read that you can test the reed switch by passing a magnet over it.

    I have never seen my cassette full lamp lit as I empty the cassette daily. If it gets too full I find it too heavy.

    btw all wiring diagrams seem to suggest that the lamp is lit by a replaceable battery located in the cassette compartment. In my 'van, a 2008 Swift, the lamp seems to be permanently wired into the leisure battery.

    Our Bailey 'toilet full' warning light has never operated properly since the day it was born! I don't worry over it - the other voice controlled system works far better. "Isn't it time you emptied the toilet!" Remarkably it never fails.

    Yes the float thing that activates the switch was stuck on ours and hence the constant red  light. I had to pull it up every time i emptied the cassette. You could take the battery out if it is powered by one.

    One time the switch arm thing came out with the contents and down the emptying point plughole!

    Ours is probably best described as pessimistic, so I know if it comes on I have some leeway.

    No idea if the light on mine works as being on my own I have to use my inner voice to say "time you emptied the loo"

    When emptying the cassette, if shaken too vigorously the device to make the light work either becomes dislodged or disappears down the Elsan hole, never to be seen again. Mine has never worked, so I reckon the previous owner of our van was heavy handed. I've no intention of giving the cassette an internal examination.
