Was clean 2 weeks ago [the cell light was flashing] the guy said it wasn't that bad. Clean the cell, DE filter.... Yesterday, the light is started to flash again.
The pool is at 70 the water was tested yesterday everything was good[don't have the results in front of me].
What could it be? This is my 2nd. cell, replaced [red salt light stayed on] it in October.
Thanks, any help will is always be appreciated !
