Must be the time for pump failures. I see a whole bunch of them posted all of a sudden.
I have a 2HP aquatools pump driven by an AO Smith motor. It ran overnight & tripped the circuit breaker. I reset it and went back out and backwashed the filter. No problem so far. Shut it off and turned the valve to rinse. The motor came on, although very slowly, and eventually the motor overload tripped.
I pulled the strainer and was able to turn the impeller by hand. I measured the resistance of the motor windings and they don't appear to be shorted, although there is a very slight burnt smell.
My next step is pull the basket assembly and make sure there's nothing stuck in the impeller. Any other ideas?
I think this pump is actually way over sized for my pool anyhow. My sand filter is 200lbs , 60 GPM, 50 psig. so I'm not sure what the correct size might be.
Thanks for any ideas.
