I have an AutoPilot Total Control system running perfectly since last year.
This weekend I cleaned my FNS DE Filter and suddenly the AutoPilot is claiming error, to the check flow.
I've tried reconnecting the tri-sensor, cleaned filter screens, and checked flow without much success. The measurements from the "test" function of the AutoPilot all came in normal (3200 salt, 7.70 pH, 667 ORP) and all other components are running normal.
Could my cleaning out the filter media have caused this problem or was it purely cooincidental?
The other thing I that happened was when the pool was opened (late April) I had to jiggle the tri-sensor a few times to get the readings to come in correctly. Was this a sign of a sensor going bad?
Any ideas what could be wrong here?
