WaterCare UCS875 Stuck in Filter Mode
Recently purchased a house with an early 2000's vintage CareSoft/WaterCare softener (UCS875EM). The main valve appears to be a Clack WS1 (5 button). When going in to adjust hardness, it displays -nA-, which after some research, shows to be in filtration mode, not softening mode. More research took me to the configuration menu (Next + Down for 5 seconds). From there, I can switch from Filtering to Softening mode, adjust the settings, then exit out. However, when I go back to adjust the hardness, it's still showing -nA-. It seems like it's somehow stuck in filtering mode. I tried to reset it by removing the battery and power for a few minutes, but no change.
Is there some other setting I'm missing? There are no error codes displayed, but is the board bad? For it's age, it's pretty clean.
