Two yeas ago I fitted a S.O.G modification to our toilet cassette and about 3 weeks ago it went from nearly completely silent operation to (for a small motor) quite a noisy one.
I at first suspected that the fan drive shaft was made of normal steel and had collected corrosion and the corrosion build up was touching something.
On stripping the fan unit from the cassette door I found that the inside fan feed pipe from the cassette and the fan body were infected with tiny wood lice type insects. How they got there or even why the went there is a complete mystery to me (A free drink to the winning suggestion)
The insects where dead or at least they did not move (quite right too) so I reconnected the power cable and run the motor and sprayed WD40 into the fan, this washed out the offending items and the unit has been as good a gold ever since.
