Well, tried 2 capfuls of vinegar, still no dice. Took it apart, cut the wires to the sensor, stripped and twisted them together, back on the floor and now it’s working! And it is putting down *plenty* of water, will be interesting to see how much is put down and sucked up.
I suppose I could plumb in a 5800 water sensor if I really want/need to, but so far so good….
