Pump impellor seized (easily fixed) or pump stuffed and needs replacement.
Pump is accessible through the toilet paper holder.

Cheers,

Thanks for info Peter, I found a 10amp fuse in the cassett compartment, checked it with multimeter Which showed it was blown, pried the fuse apart & found the metal bar intact, not blown. Closer look at the fuse blades showed a light film on them, put it back together & cleaned the blades & thought ,your a clever rabbit, found the problem, checked switch terminals & power was there so put all back together & still did,nt work! Will pull pump out tomorrow as per Your suggestion which most likely will be the trouble, would never have known it was accessible from that location, Will update on progress, Joda.

New pumps are about $80 and readily available from many sources.I purchased mine from RTM. It took about 90 min to replace.

Hi Joda,

Check your main 12v fuse panel as well. I had a similar issue, and found there was a fuse for the toilet in there as well - blown.

The blown fuse generally indicates a pump problem.

All good, pump was stuck, sprayed impellor with silicon & a poke with small screwdriver brought it back to life, at least I now know there is a 10amp fuse in the cassette compartment, Joda.
