Many thanks again. I did replace the electrodes some years ago and
also the solenoid. It is the stove timer sort of dial. The cleaning
instructions I had not seen before. Indeed, the new manual is a vast
improvement over the one I have, which is pretty much
incomprehensible.

If we don't add salt, we get visible effluent and odor. If we add
salt, there is neither visible effluent nor odor.

Then the answer is obvious: you need to add salt. 'Cuz odor and/or color
mean the unit isn't treating. If adding salt corrects it, then that's
the problem...But unless LIS is a lot more brackish than I thought it
was, you shouldn't have to. Low voltage can also prevent it from
treating. So I strongly suggest you have a chat with Vic. He's been
there 30 years and knows more about the older systems than anyone else
on the planet.
