My Jacuzzi magnum 1000 is not filling with water, there is an air leak somewhere and I cannot seem to find it. I have replaced the O-ring on the top of the machine, as well as the 2 plugs on the bottom left side. What can I do to fix this problem?

This sounds like it could be the shaft seals, which is a cheap fix. The Jacuzzi Magnum calls for seal 35-423-1021 You might consider replacing the seal plate O-Ring as well. - 35-105-1120
Where is it leaking? if it is still leaking between the wet end which is the black plastic water housing and the motor then the seal is not properly set.
If the water is leaking from the trap lid then the o-ring is not properly set or the lid is cracked. Try using some silicone based lube on the o-ring and then reset the lid making sure the o-ring is properly resting on the outer lip of the pump pot.
I think you have a air leak. A 1.5 hp motor is very strong and should vacuum well. Be careful to not over tighten the top of your pump housing.
Is your impeller in good shape? It may be worth your while to remove the pump motor from the pump. While you have it apart, replace all the seals (there is a kit for this). Inspect the impeller and all parts of the housing - any junk inside? Remove it. After you complete the rebuild, reinstall the motor, fill the pump housing with water, secure the top and start the pump.
the o ring usually would not fit if it were the wrong size. What seals is a ceramic seal, did you change that? If run without water, the ceramic seal will be damaged....
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
Your motor is going bad if it get's that hot. It is kicking off when it get's hot enough to the heat switch in the back of the motor. This resets it self and the motor probally comes on again after a few minutes. The wireing in the motor has a small short that will get worse soon enough and may even catch fire if the conditions are right. So you should get a new one and replace your seal kit and "O" rings at the same time. Odds are a small water leak got this started. Good luck
Loosen the motor and impeller from the pump by backing off the large plastic nut and take that whole section to an electric motor repair shop for inspection. If the motor is salvagable, they can quote the repair or replacement.
