My Hayward Tristar 1.50 HP pump is 3 years old, and recently developed a high-pitched humming noise that is causing a noise disturbance. The performance seems to be operating okay, but it never used to...

sounds like the bearings are going out on the motor. The noise will increase as they wear out more until it locks up and throws the breaker. You can have the motor rebuilt or just replace the motor. Consult a pool professional to help out with this.

Was pumping good, water level got low and pulled air. Pump now has very low flow. Pump is a SP3207EE

If it ran very long you could have overheated the plumbing and now you might be leaking air. If you can get it to run right by putting glue around the suction pipe at the pump while running this is your problem. If so you will need to replumb pump. Do the suction and the discharge as that will probally leak also.

I need to change da motor from 110v to 240v to work at home

You can only do this if motor is made for this kind of change. The motor info plate will have a connection chart to show you if you can and what connection changes you must make. Also, the pressure switch must be a 2 pole (double contact pole) switch if you use it on 220 to 240 volt because you now have 2 hot wires and a neutral (not just 1 hot wire and neutral as in 115-120v) , and you must have a pressure switch that disconnects both hots ----therefore it must be 2pole.
Good luck, Macgivor

Have hayward 2speed pump and cant get speeds to change ontime clo

If I am following your description correctly it sounds like the booster is tied to the wrong clock...You want the booster to run with the high speed which is 'the other' timer it sounds like.

What does the red switch on the back of my dell dimendion e510 do

Don't! That's for foreign voltages. It should say 115 and 230. The 115 is for 120V systems while the 230 is for 240V systems. The actual voltage you get is usually a little less than ideal, so they design power supplies to accept a lower voltage.
