Our pool is almost 2 years old and everything was working fine yesterday. This morning I notice the water is not moving at a time when the pump is scheduled to be on. At the control panel the breaker for the pump motor was tripped. I reset the breaker and the motor turned on for about 30 seconds and shut off. The motor sounded strained to me, but that's subjective. Apparently, it's the thermal overload that's shutting the motor off. Once it cools, I can run it again for about 30 seconds.
I've checked the voltage and amperage to the motor. It's on a 240VAC circuit. The voltage is fine, the amperage is high. But, that's to be expected at this point.
I looked at the pressure in the filter when the pump was running and it's about half of what it normally runs.
So, to me, it appears I either have a defective motor, or something is wrong with the pump that's putting a large strain on the motor. I'm actually leaning more toward the pump. How can I determine the cause? What I have is a Hayward TriStar Pump Series. Is it logical to just mechanically separate the two and run the motor with no load?
I'm about to head out to a Titan's game so I won't have time to work on this until later this afternoon. I appreciate any assistance you can offer.
