About two weeks ago, I had the classic No Cell Power msg on my AquaLogic PS-8. I removed the board, found the burned out joint, and resoldered it per the recommendation. Put it back together and all was fine for a week. Now I am getting the Cell Power Error message. I cut the power for 10 minutes and it comes back up, runs fine for 2 days or so, then I get the Cell Power Error back. I have read various posts on the new that range from the system board is bad vs the salt cell is bad or needs to be cleaned. Any thoughts of where to look next is much appreciated.
