(quick backstory: similar issues at the end of last fall, though not as bad as it always started - during this spring opening, pump worked without issue until now)
I had my pump off for the majority of the day, and came back to turn it on in the evening
It made a very loud buzzing noise and would not start.
Left it off for the evening.
Buzzing, not starting : Pump buzzing - no flow - YouTube
Next morning, I removed the end cap, ad was able to turn the shaft, it did not seem stuck and turned easily.
Then I turned on the power, and it did start, after some non-typical noises and a very slow start - it is now running.
Starting and running: After manual spin - startup - YouTube
It has been running for a few hours, though has a sound that is different than normal (sort of a pulsing sound, which is not typical)
Running: After manual spin - noisy - YouTube
Any thoughts on if this may be
- capacitor related (starting issue perhaps - but what about the noise it's making while running)
- bearing issue?
- something else?
Thanks very much for the input.
