Hoping Pool Clown can help with this issue. Salt water pool 6 years old. Water level and flow are fine but Aquapure Zodiac system keeps blinking no flow. I have cleaned filter and salt cell. I noticed one panel on cell was all chewed up and swapped it out for a full panel. I have read many posts and they all talk about a flow sensor. I can't seem to locate mine unless it's internal somewhere. Just cleared an algae issue and would really like the system to run to keep the water clear.
