My Saniplus, about 4 yrs. old, is just emitting a hum and not pumping.
Having taken the unit apart, there is nothing blocking the blades, etc.,
and the
impeller turns freely, so I suspect the capacitor and would like to try
replacing it before contemplating new motors, etc..

Can anyone tell me where the damn thing is?! The schematic shows it
alongside
the pressure chamber, but I can't see it. If it's inside the chamber, how
do I
get at it?
I've taken the membrane off but that doesn't help.
