I recently had my IC60 fail somewhat violently. I came home to find the top portion or “cap” of the cell laying a good 15-20 ft from the equipment pad with a burn mark on the inside of the cap and a small puncture through the black membrane inside the cell. Very similar to the images in this thread: Top panel blew off IIntelliChlor IC40
It has been replaced, but wanted to see if anyone had any theories on what may have caused this, to hopefully avoid it from happening again.
Would it be plausible that a flow rate at or near the trigger rate for the flow sensor could be the culprit? Just speculating that maybe the control system implements poor or no hysteresis, and that with a flow rate near the trigger rate for the flow switch, it could have been rapidly being triggered on and off, causing some sort of issue. I’m only throwing out that guess because I do run the pump at a low speed for most of the day, and once I lose enough flow that the spa stops or nearly stops spilling over, that’s my cue (and right on schedule anyways) to backwash the filter. So the flow rate can get awfully low, and while I wouldn’t let it get to zero, maybe I got too close?
