Could be 2 reasons. If the pump is on and you are hearing a humming noise, it could be a bad capacitor. The capacitor is what starts the pump by giving it a kick start of electricity.
It could also be a seized motor, when it tries to start, it will also make a humming sound, and eventually trip the breaker.
The way to test if it seized is try to turn the motor by hand (Make sure the power is off). If the motor can't turn then it's seized.
Water sprayed on the pump occasionallyshouldn't hurt it but it might cause a ground fault circuit interupter (GFCI) to trip. If you turn on the pump and literally nothing happens then most likely the the GFCI has tripped. If it hums then this is a different issue. If you have a volt meter you can open the timer box and check whether power is available to the timer. If no power is available in the timer then it confirms that the pump is probably ok. Checking your circuit breaker panel for a tripped breaker or finding a tripped GFCI then either one can be reset and your pump will probably run without a problem.
Inside pump is a difram , it most likely is stuck, some times if you shut off pump, turn back on a few times it might release itself, but most likely needs to be replaced. Let me know, mike from fixya.com
DIRTY START SWITCH OR AND COULD BE THE START CAPACITOR OR RUN CAPACITOR,. RUN CAPACITOR IS ON TOP OF THE MOTOR. I WOULD SUGGEST YOU TAKE THE BOLTS OUT AS PICTURED AND BRING IT TO YOUR LOCAL POOL PUMP REPAIR GUY WITH FREE TESTING.. SEARCH YOUR AREA FOR HIM ..JAY LONGWOOD FLORIDA
the pump motor has a short in it, most likely to be in a field coil it may be repaired but its likely to be far cheeper to replace the motor and there should be a way to turn it off,,,the brakers will trip every time the motor starts to humm becouse the motor is pulling far to many amps for that trip so to save a "fire!" it trips out,,,,do yourself a big faver and have it looked at fast
What exactly is wrong with your pool pump? If it won't start at all, check for improper or loose connections, blown fuses or tripped breakers, and open your switches and replays. Manually check the rotation of your motor shaft. Make sure that there is free movement and no obstructions. If the motor hums, but won't start, check for obstructions and check the Centrifugal switch to see if it is stuck in the open position. If you have low flow, check pool pumps for clogged or restricted strainer/suction line and discharge line of filter. You could also have an air leak in suction (bubbles issuing from return fittings). Low voltage could cause loss of suction. Check for plugged or restricted impeller.
The motor may have blown the start capacitor. It is the black cylinder about 1-1/2" dia x 2-1/2" long. Look at the end with the wires for a small hole. Is it blackened or have a hole blown thru? If so replace it. Otherwise have a local electric motor repair shop look at it for possible repair or replacement.
it sounds like your pump is stack it could bee that something is stack in the pump, try somehow to turn the motor to see what is binding get accessthrue the pump.
