Update: Contacted Pentair this morning and after only a 5 minute wait explained the problem. Tech said probably a flow switch and was going to open a case and have a rep come out to replace the switch. I told him just to send me the switch and I would replace it. After looking for their closest rep, he said the nearest one was far away, would cost a lot of money and that he would just send me a new switch, Fedex the next day. Told him I am a retired EE and would be happy doing it myself (way better than trusting a 3rd party guy and not knowing when he would show up). The Pentair rep (Chris) said that if the new Flow Switch did not solve the problem, they would send me a new IC60 (yay).
When I called Pentair, I assumed the warantee was for 60 days for a self installed part. NOT true. Intellichlor products have a 2 year warantee, even if you install it yourself. As a side note, when talking to the Pentair rep, he asked if I had done a horizontal or vertical install. I told him I did a vertical install because I did not have the space for a horizontal install. Surprisingly, he said that the vertical install seems to last longer because when the water flow is off, water does not remain in the cell. Don't know about that. When I remove the cell to replace the switch, I will see if water spills out. Going to remove the cell and do the Flow Switch swap on my workbench instead of leaning over with my 73 year old bad back.
Will update when the Switch gets installed.
