I posted this question on Pentair's support forum 2-1/2 days ago, but have heard nothing from them as yet...so I thought I'd try here and see if anyone has any ideas what I could do or check...
My 3-1/2 year old IC40 was no longer staying on reliably. Sometimes I'd check in the morning, and see there were no lights on the unit. Turning the pump off and unplugging/plugging in this unit would bring it back to life (although I sometimes had to do this 5 times before it would stay on).
So I decided I might as well purchase a replacement cell, and got a new one off Amazon. I checked, and am able to adjust the cell operating percentage via my Easytouch panel, so I think the two units are communicating.
Now I'm seeing the following:
The unit comes on just fine, but the green and red Salt Cell lights will flash on and off alternately. Sometimes the unit will begin giving normal readings (only the green Salt Cell light lit), but that lasts only a minute or so before it starts alternating the red and green lights. And once in a while it will flash only the green Salt Cell light, but that, too, lasts only a minute or so before both the red and green lights start blinking again.
I checked the salt level of the pool, and it reads 3200 ppm, so the salt level is OK. The rest of the pool readings are normal, too.
I'm wondering if anyone has any ideas what might be wrong here? Is there a reset sequence I could try? Is this new cell not compatible with my 3-1/2 year old Easytouch control panel? Is there something failing in the Easytouch panel?
Is there a sure-fire way to know if this new cell is good or bad?
Any assistance here will be greatly appreciated.
