My intellichlor keeps showing a flow error light. I'd opened the pool in March and it was working normally until recently.
Things I've tried:
1) Increased pump speed
2) Reapply silicone to pump lid seal
3) Removed vacuum from Vac-mate to allow for maximum water flow.
4) Back flush filter - I'm not doing a full back flush, just pulling the handle up, and then pushing it back down when I see the flow light go green. It takes seconds.
5) Cleaned the intellichlor - did this first, even though there wasn't that much build up.
I thought it might be the intellichlor, but I notice a lack of suction at the vac-mate and pool cleaner.
Any help is appreciated.
