Literature on Thetford toilet says to replace batteries if the "full" light isn't working, but it doesn't give any info on where the battery compartment is. Anyone know?
If you open the toilet cassette door and look at the model and serial number of your toilet, then go onto the Thetford website and look up the exploded drawing of your particular model, that will show you where the batteries go.
Generally in a small battery holder inside the toilet holding tank in the locker. Should be a couple of AA batteries. Open the door you can't miss it ( at least on the last 3 vans I have had)
