I have had an Aqurite (AR) chlorinating system installed on my pool for probably 15- maybe 20 years. Last year I upgraded the Pentair automation from Suntouch to Intellitouch (IT) . I replaced the AR control box at the same time- the original has some dark areas on the PCB and the tranformer also had some dark spots on it. The AR is connected to the IT via the 4 wire com ports. The cell is an aftermarket t-15 and has worked as expected since install a couple years ago. The system has been working as expected until about a month ago when I had no cholrine when tested and discovered the no flow light blinking.
Trouble shooting included:
Filter was cleaned and elements acid/chlorine washed. good flow and pressures on restart. No leaks or air bubbles
- Tested the flow switch (hinge type) which had good continuity tested at the RJ-11 plug with pump running. I replaced it with the metal leaf contact type just for comparison- solid continuity when pump was on. good pressure on filter gauge- NO FLOW Light went off for a short period when the pump was started but then started blinking in less than 1 minute.
- I jumped the RJ-11 contacts on the PCB with a flat head screw driver- no change
- Replaced PCB with aftermarket, verified that the T-cell 15 was selected and started the pump- no change
-Retested flow switch- good continuity
-Jumped RJ-11 contact on PCB- no change
Looks like good pressure and the flow switcvh is functioning properly.
What am I missing?
