It's likely that the bearings in the motor have rusted from sitting up for 6 months. This causes resistance which in turn causes additional heat inside the motor. This is a water cooled pump that is designed to move just enough water through the pump in order to cool the motor under normal operating temps. Because the motor is running hotter than it was designed for, the motors thermal overload shuts it down. You can replace the bearings (hard) or replace the motor (easy). You can find the motor and the bearings at

SOURCE: I have new pentair 1 hp pump that was intalled by

to open the basket the pump needs to be off. all drains and the skimmer needs to be shut. otherwise all the water from the pool will leak out... now when you have done all of that. there should be a ring around the lid you take a hold of that and twist. it can be alittle stiff at first.. When you get that ring off the lid will pop off. now water will come out of it becuase it's just what's in the pump and in the line. once the water is out you can take the basket out and clean it. Now very important. when you put the lid and the locking ring back on open the skimmer and the drains to get water back into the pump. If the pump is not filling up go ahead and automatically put water in there until it's full. once the pump is full you can turn back on the pump and everything should work fine. if you have any other questions please let me know.

SOURCE: Will Pentair Intelliflo pump save me enough money to justify cost

Here are a couple of thoughts. If you install an intelliflo pump and run it for the same amount of time and at the same rpm as your current pump, you will still have a savings. If you drop the rpms by 1k, you will have an exponential savings. Go to the pentair website and use the program to estimate your actual savings. You can still run the heater at a reduced flow setting but there is a limit, you have to check with the heater manufacturer to see what the minimum is.

If you are running a conventional pump 24/7 you are using a ton of energy. You should be able to run the pump for 8 hours a day and achieve the same results. For instance, running the pump from 4am to noon should give you a good window to maintain the heat and not run it all the time. It also depends on if you have a cover on your pool when it's not in use. If you don't, you will lose significant heat when it's not running, however, running it early morning should give it a chance to heat back up before you want to use it again. You will have to experiment with timer settings, etc..

I really do think the intelliflo pump is a great pump. The rare earth magnet design allows it to be way more efficient than the conventional pump. It is so much more efficient that when it's running, you can hold your hand on the motor and it is just warm. Your pump motor probably runs very hot, heat is a by product of inefficiency. I hope this helps.

SOURCE: What are the specifications for

Take the cover off of the is the bump on the top of the motor...then look on the capacitor and find the numbers that end with mfd. that is the size or rating of the capacitor...also then look for the voltage of the need to match that also...there are so many different motors used, even for the same pump that it is hard to say for sure what you may need there with out looking at it.
You can do that and then you know you are getting the correct cap for your motor...
My guess is that you are looking for something in the range of a 20mfd 370volt cap. but please check it out for sure they vary alot!!

It is probably only getting 115V from your circuit which will cause it to overheat and trip the overload yet it will not draw high current which would trip the breaker. Can you confirm your line voltage with a meter? If it is suppoed to be a 230V line then look for a bad leg of power, again, checking each leg to ground using a meter.

Sounds like you have done eveythig correctly - since the pump is new I suggest you contact the seller of the pump, or the local service agent as it could be a thermal overload problem.
