I have a year and half old Hayward motor that has recently developed some issues. One day I noticed the pump had not started and the breaker was thrown. I attempted to start the pump manually and the pump hesitated for 4-5 seconds and then started like nothing was wrong. The next day it started automatically but the following day I again found the breaker thrown. Restarting it resulted in the same 4-5 second humming but this time it blew the circuit breaker. I flipped the switch back on and it hesitated again and then turned on and subsequently functioned without an issue. With the electricity off I manually turned the impeller and it rotated without any resistance. I have also removed the capacitor and tested it with a multimeter and it seems to be good. Anyone have any thoughts on what would cause this hesitation in the motor?
