I just had my six month old Hayward Aquarite board replaced 'cuz it was randomly changing the T3-15 setting and showing zero instant salt ppm and sending zero current to the cell. Eventually the display was just showing gibberish.
The new one is showing zero ppm on its instant reading and sending zero current to the cell, unless I turn the knob for percent chlorine generation above 50-70%.
Is this normal, or do I have a bad cell, or perhaps a new, but bad board?
Thanx in advance for any insight.
