It would stop generating chlorene, the generating light blinks, and the readout is "Cold". I was told by Hayward that the cell was dead. I replaced the cell a few days ago, but the problem continues to persist. If I turn the swimpure to off and on, it will seem ok and start generating again. This will be ok for several hours. I am positive that there is ample salt in the water, but I am not convinced that the swimpure readout is accurate. Could it be a bad circuit board?
