Have a Jandy 1400 throwing 120 & 121 codes. It's 2 years old and was a warranty replacement of another cell so I'm thinking I don't get warranty coverage. Nevertheless, I pulled the DC cable from the cell and the center pin is loose and can almost be pulled right out. There is also a drop of water leaking out very slowly. Is this corrosion of some sort? Is it normal that the pin is loose? Is this a defective unit and might be replaced at no charge to me? Any ideas? Thank You
