Hi can anyone advise where the fuse or resister is for this toilet mine is not working and having read up on it there is a fuse or some have called it a resistor behind the flush tank but I don't know how to get to it, I had a friend check the power to the PCB and that's ok but there's no power going to the pump, he has checked the pump and that is working but was a bit slow to start with but fine now so we thought we would check the fuse first???
