I have been battling a Polaris booster pump issue for a while and while many posts are close to the issue, this one seems unique.
My pump will not start on its own. I can energize it but no flow. Once I hand spin the shaft, it comes flying on and works like a champ for hours. I have checked the voltages and it reads fine. I have completely uninstalled it and opened it up to check for internal issues (impeller, etc) and installed all new seals. I have changed the run capacitor out twice with new ones of the exact same rating. I have tested the capacitors as well to make sure they work well. I confirmed through replacement that the supply valve is clear and fully open and my main pump runs well with good pressure. I am at a loss. Can the actual wires to the capacitor be broken and it still run? It appears to be a run capacitor and not a starting capacitor based on its numbers.
Another observation is that a couple of weeks ago, there was enough flow through the pump that it would very slowly spin the shaft while off. More recently, that is not the case.
Like I said, all I have to do is give it a slight twist and it takes off.
Any ideas would be appreciated... would love to get back to it cleaning on a schedule.
