Older 2HP Whisperflow on 35Kg pool with Sta-Rite (big one, don't have size written down) DE filter.
Turned pump on this morning and it just hmmm'ed with no spinning. I then turned it off.
2nd try, hmmm'ed for about 3 seconds, then started. Then I turned it off.
3rd try, hmmm'ed for 3-5 seconds. I turned it off.
4th try, hmmm'ed for 3-5 seconds, internal switch in pump turned it off. Waited 5 minutes...
5th try, hmmm'ed for 3-5 seconds, pump finally started spinning. Let it run its cycle, but removed the "On" pins on its and the booster's timers.
Since the pump is old, if the fix isn't easy/cheap, may just replace with a 4-speed Intelliflo (or similar 2-speed pump).
Any ideas? Simple fix?
