Freeflow spa 2hp motor, when running seems to have lots of flow ran for 2 weeks without trouble

if it is a used pump, these have a tendency to have a little rust. just get some pump pliers and rock the shaft gently back and forth. then plug it back in.

Probably the heater. Turn the heat off and try it. There should be a flow switch to prove pump is on before the heater works, but sometimes if you're running low, it will work intermittent. Do you know how it got low? evaporation? Is the pump leaking? If the pump is leaking, and has leaked for awhile it may have shorted out the motor. While running the pump low on water will damage the mechanical seal that keeps the water in the pump, it should not affect the motor itself.

Thank you for posting your question here on Fixya.com. Something is causing the pump motor to overheat and shut off to avoid permanent failure. The motor is likely failing. It may be a small part such as the capacitor or the starting switch, but could also be more severe such as the winding itself. You will also want to examine the shaft to see if it is damaged, bent, or the bearings failing or seized. If this answer does not fix your problem, please comment with additional details prior to rating the answer. Positive feedback is appreciated once your problem is solved!
If you are not familiar with testing these parts your best bet would be a local electric motor repair shop to see if the motor can be repaired or if it would need to be replaced.
*All of this assumes this is an older/existing installation that has worked properly in the past and is just now showing signs of failure. If this is a new install look at your line voltage versus the voltage the motor is set to accept. If feeding 115 to a motor wired to be on 230 you will also get the situation you describe.

It sounds like there was a lack of water to the reservoir, which is, I assume the inlet reservoir with the basket strainer in it.
1. Is your water level in the pool high enough to keep the reservoir full?
2. There is an o-ring or gasket on the reservoir cover, is it there and lubricated so there is no air leakage?
3. Put a garden hose into the open reservoir to see if the pump moves this water out.
Do all of this with the filter set to just go back to the pool so you can see the results.
Try this and comment back.
Good Luck,

what happens is the pump gets staved for water and this damages the shaft seal, water slowly over time leaks into the motor and pollutes the grease int the bearing and causes it to fail. it's fairly easy fix, just have the motor rebuilt by your local pool pump motor repair guy for about 75.00 and your back up and running. beats paying 200.00 or more for a new motor.
the sta rite is the top of the line pump, i have had them in my shop over 40 years old ! ask your motor repair guy how to get the most life out of your pump. knowledge is king .. remember to prime the pump after any pump repair !! .. jay longwood florida
