It could be the capacitor again, but most likely if it stopped while running, its not that, unless you had a brief power failure. The motor may have a built in thermal overload which turned the pump off. If it only humms then it could either be locked up by something in the impller, or could be the bearings in the motor have failed. If the motor doesn't smell "burnt" then you might stand a change to disassemble the pump. Disassemble the motor and replace bearings. Replace the mechanical seal while you have it apart. OR you could buy a new motor, as it is 10 years old.

most likely the bearings are starting to go.

The impeller is threaded onto the end of the motor shaft and the housing (pump body) is attached to the motor with the same bolts that hold the rear cover on the motor they run all the way through on most pumps.

You should be able to remove the diffuser and then the impeller to gain access to the shaft seal on these pool pumps. Your users manual should have a diagram.

alot of companies use to have a damper ring on pump shaft which would knock down some of the noise a pump motor made pumps make noise and the bigger the pump the louder the noise if its not vibrating or clunking then its running as it should
