My polaris PB4-60 booster pump does not turn over.

I was able to save a service call by doing the following in under 8 minutes:
1.Switch off electric to pump.
2. Turn off valve on supply side of pump so water does not flow during this procedure.
3. Turn offf filter.
4. Unbolt the six bolts (1/2" socket) on the front side of the pump.
5. Carefully separate the pump from the front panel which contained the six bolts.
6. Grasp with both hands the black round thin disk (impeller) which is part of the pump and turn it either clockwise or counter clockwise. It may be slightly difficult initially but once it it freed it will move easily.
7. Reassemble.
8. Open valve and turn on filter and the power to booster pump.
