    Circuit Breaker Issue

    After a cleaning, you start the pump with it having to prime itself. Pushing air is a lot easier than pushing water. So it could be a load problem. Experiment some.

    My gut feeling is the circuit breaker, but only because I had a weak breaker once in the 220 line to my electric range. I could run two burners no problem. But try to use the third or start the oven, and nothing worked because one side tripped. The hardest part of replacing it was identifying the brand and style of breaker.
    After I clean the strainer baskets or any filters, etc., the timer works properly and the pump comes on. The inrush current from the pump coming on can be enough to trip a weak or old breaker. Probably a good time to put the pump on a GFCI breaker as well, if it isn't already on one. 2nd guess would be a problem with the pump like something binding the impeller or shaft, increasing the current being pulled by the pump when it turns on. I'd probably start by replacing the breaker. Any help would be greatly appreciated. Just moved into an AZ house with a pool about 10 months ago, so still learning. One morning our pool pump did not come on. The circuit breaker had tripped.

    Any subsequent times after that, when the timer is supposed to come on followed by the pump, the circuit breaker trips. Hayward Super II Pump 1.5 HP, Has anybody else had this problem? It was driving me crazy because it would work one day, then it wouldn't for a number of days, then it work a day, etc. That's when I figured out that it works the time after I need to do something to the system, but not any times after that. Don't know if it's a pool equipment issue or an electrical issue, maybe AutoPilot DIgital Pool Pilot?

    It's pretty common for circuit breakers to get weak over time and start tripping, especially when controlling high inrush loads such as motors. I'd replace the breaker first and see if that solves the problem. And as you said it would be good to put it on a GFCI anyway.
