I have a Goldline Aqualogic PS-4 SWG and am getting an error message that indicates no flow to the filter/pump. When starting the pump, I receive a message that the chlorinator will start in 30 seconds. Then an error message indicates there is no flow and the the chlorinator shuts down. The pump stops after about 15 minutes.
I have plenty of flow on startup. I suspect it is a flow sensor. I have a tendency to scale. Where do I start?
