Newbie here... Please tell me if this isn't the place for my question, and where I should post it -

Is it practical/easy to open the head and correct this? My Kinetico 2100 FOD dual tank filter (ca. 2004) won't stop regenerating. A rust film on the disk keeps me from seeing where the indicator is in the cycle. Push&Turn, I can feel minor clicks and the head switches to and from Regen and Purge but water never stops flowing water unless I bypass the filter system to cut off H2O pressure. Any help appreciated!
