Just wanted to post this as an FYI for people seeing the same issue - for the past few months I've notice the power cord on my Pentair Warrior SI (same as Maytronics S300 / Active 30) has been sticky. I saw some other threads on here where people had the same issue and got warranty replacement. I was being a bit lazy about getting that taken care of, now I see my cable has bits of rubber coming off it. So I called up Pentair, gave them the serial number, and they are sending me a new power cable under warranty. If anyone else is seeing the sticky cable thing, probably better to get it taken care of sooner rather than later before the rubber starts sloughing off like mine and getting up in your pool filter.
