I have a slightly different problem: the water softener (Kenmore Elite) is running continuously, or at least is sounding like it is running continuously. No leaks, no water in the tank, and salt level appears to be holding steady. Might need a new one, or maybe just repairs. I’m going to run its regeneration mode overnight and see if it might reset itself. If it still is running tomorrow morning then I’ll probably look for a new one.
