Due to careless installation, the output tube on our pool pump (hayward super pump c48k2n143b1) popped off during operation during the night after opening our pool, and it ran for long enough to bring the water level below the skimmer, therefore resulting in the pump running dry for an unknown amount of time. Since then, I have been able to prime it and get it to start pumping, with significant visible flow at the skimmer, however, after about 15 seconds, it consistently trips our 15A breaker. Now I am aware that the pump draws maximum 15A, but this has never caused problems before, so I was wondering if anybody knows what might have caused this. My theory was that due to the unloaded and uncooled operation, thermal or physical damage to the motor and/or bearings resulted in increased internal rotational or winding resistance, causing higher current draw, but I have no idea if this would have actually happened. I've also read that damage to the seals would have likely resulted from running dry due to thermal buildup, which might cause problems if there was leakage between the inner and outer parts of the impeller, but due to the fact that it seems to prime properly, I'm not sure if this is the problem and even if it would lead to the tripping of the breaker.
Thanks in advance for any assistance
