Received a maintenance update from our clever mechanic, Nick. He said that it was not a filter issue, but a "Impeller Issue".
Nick said that no water was making into the generator for cooling. My reply was that I checked for water flow (I did...) and saw water coming out of the exhaust.
This is why I am in insurance, and not a mechanic! The Nickster is running probes around the innards of the cooling system, looking for rubber impeller blades. The other issue with the sanitation system has been isolated and a pump replacement is in progress.
We pay for professional maintenance so that things work. Whenever I do these small repairs, it means taking three trips to various parts places untill all gaskets, fasteners and special tools are acquired, usually with the job hanging there half completed.
Really fun when the parts store clerk speaks only French or Spanish. I have had these problems before, in far away places, where I didn't have a car to get around.
