Check/Clean Cell Purifier off

[Poolsean]

It sounds like its a bad power module, unfortunately.

This might not make sense but I believe in trying everything before ordering new stuff

I had a check/clean cell warning one time and like you even though it didn't look really dirty I cleaned the cell as directed but the message came back shortly after putting everthing back together. After playing a bit (cleaning contacts, etc) I finally thought about checking the inline filter screen and even though I didn't have a flow warning it was pretty dirty so I cleaned it out and Viola!! the message went away.

I didn't get as far as checking voltage/current readings and have no idea why the system was reporting cell warning rather than flow warning (which it does when the filter screen gets really dirty and the pump is on low). Maybe it triggered both alarms and the cell warning has a higher priority so it was the one being displayed and would not clear until the flow was sufficient to check the cell. Perhaps Poolsean can explain or tell me I'm crazy or it could be one of those pool mysteries that is never solved but it worked for me so maybe it will work for you!! Good luck.

dc, you're crazy! lol
The flow is the priority protection so there must have been enough flow to trigger the flow switch but not enough to saturate the cell with water to achieve full amperage and voltage to the cell, hence, Check/Clean Cell.
It is unusual for that condition to exist, sooooo..... I would suggest checking to make sure your tri-sensor is working correctly. Block off flow to the tri-sensor and ensure you get a Check Flow warning.

I haved cleaned everything, even the contacts with CRC electronic cleaner. I've had the system for 4 years out of the weather. I can understand the cell getting used up, its design for that. But the control module? if your gonna replace the pcb, it seems more cost effective to buy a new control module. The internal components are too expensive. Does anyone have reviews on Jandy Aquapure. The replacement components are cheaper to replace if they ever go bad.

Its been a while back from a long sabatical. I rechecked everything again after being without a SWG for about 7 months. I found 4 of the medium size capacitors on the power control board to be swollen. I desoldered them and checked and sure enough they were bad. I ordered them online for $1.50 each. I replaced everything and I'm up and it's running like new. I came close to buying a complete control unit. Thanks guys for all your help.
