I have a kenmore Water softener Model # 625.3484500 that I can not get to regenerate automatically? I have ran the manual initiated electronics Diagonostics and all is well. I can do a manual re charge ok. I can get the screen that showes the time but does not show recharge tonight at botton of screen as discribed in operators manual . Is it the computer? since I cannot afford a 200.00 dollar face plate computer can I keep doing the recharge manually as needed? felinezoo.
