My Intellichlor IC40 is ~4 years old. Low salt light was on last night so I added one bag as usual. Noticed this morning the Cell light started flashing green. Acid washed three times today and the cell light continues to flash. Disconnected the power for >45 minutes to "reboot" the system, no help still flashing. Holding the "more" button indicates I have ~60% cell life remaining. What to do next?
Thanks in advance,
