    First post - pump comes on and hums but won't pump

    I have been a longtime lurker and have learned vast amount here! Thank you! I finally have my first question that I can't find an archived answer for (and I may just not be searching the right terms).

    After a wonderful first season with our pool, our Intex CS15110 filter pump (and saltwater system) now turns on and hums but does not pump at all. It hums for a couple of minutes until the Low Flow light comes on and we get a Code 90. We have tested that water can flow freely through the entire system, so there's no clog. We believe that there is no air in the system either. Any other ideas?

    Yes, there is a good chance it is the starter capacitor. You can google some DIY solutions if you are handy. If not a motor repair shop can fix it for you.
