Priming the pump just means to allow any air that is trapped in pump to escape. Open the skirting on the spa to expose the pump then loosen the union on the front of the pump and allow water to leak out for 10 seconds then re-tighten the union and turn the spa power back on.
The pump that supplies water to the heater is the one you want mainly, but you can do this to any pump you find inside.
OK you have the pump on left side and in the front center of the pump you will see the Black union that screws onto the front of pump. Loosen this union so as to let water leak out for 10 seconds or so then re-tighten the union and turn the breaker back on and the pump should start to push the water through the system. If you cant get that union off you can loosen the white union on the left side of the control box in picture 2.
The PR means prime and that is fine it means it is starting up in normal mode. Now that you have a buzzing sound that means the pump starting capacitor is not working. This is located on top of the motor under a bump cover or in the back of the motor inside the wiring plate. You would need to remove the pump from the spa and find the capacitor and replace it with a new one of the exact same number. Now with that said, it is most likely the capacitor but it may be a bad pump as well (frozen shaft) in this case you would need to have motor re-built or buy a new complete pump.
The OH code you got was overheat and that is usually a bad high limit or thermostat, but since the pump is not working that could be the reason for that code as well.
Well that is up to you. I can be a pain to get the pump out of that location but replacing the capacitor is easy.
