I was receiveing a no salt reading. Installed a new t-15 (compupool). Old Compupool was over 3 years old. Still no salt. I tested salt level with strip and I have salt. Tried the instant salt test and nothing. It has been abput 18 hours since installed. Here are the readings:
82, 32.4, 0, 100%,-0, AL-4,r 1.32
Could it be the mother board? I replaced the diode in the upper right last year.
