When I turned my pump off to backwash and then turned it back on it made a humming noise then stopped running. Now it is doing nothing. what could the problem be?


sounds like a bad start capacitor, or there is something (rock, sand, or some debris) caught in the impeller.

The start capacitor not working will cause your motor to hum, then it will overheat and trip the high limit. It won't attempt to come back on until it has cooled. It's a common problem.

try clearing the impeller first, if that doesn't work and the motor shaft spins freely, then it's a capacitor.

I plug in the pump it hums, the shaft spind freely however the motor when plugged in hums, can the bushing around the shaft be placed wrong or something?


Couple things to consider.... First off when you plug it in, or hook it up, are you doing it with the impeller and diffuser attached? If so the diffuser can rub on the impeller and cause it to scrape, and make a noise. If your running the motor free load meaning nothing attached to the shaft, well it will naturally have a low humming sound no matter how new it is. If however your sure it's louder than it should be, the bearings can certainly be going out. Is this a new motor? if not then how old? It's not uncommon for a motor over a year or so start having problems with the bearings. It is unlikely the bearing on the shaft is missaligned, but if the four bolts holding the motor together have come loose, then the front and tail pieces could have shifted allowing the rotor to rub the stator. Also if the bearings are worn and/or starting to go out, they may sound perfectly normal when spinning by hand, but at high speed can make significant noise.

The impeller is still jammed you need to get it cleaned out. You can try with a pair of needle knose pliers if that doesnt work your gona have to remove the pump bolts that hold the motore to the pump pod. Remove the bolts around the motor and seperate it this will give you better axcess to the impeller. Clean it out and try to move it if the impeller will not spin freely with the debris removed the motor has burned up .

Pump does not turn on except for a humming sound and shuts off jumping the electric breaker


This could be anything from a stuck impeller to bad windings in motor. If you open the pump at the lock ring and remove the difusser from the impeller you can see if you can spin the impeller, If it won't move is it something holding the impeller up remove it. If notit is probally a bad bearing and you should replace the motor. If the Impeller turns try turning it on and caerfully try to spin before it kicks the breaker. If it is sort of stuck and does not want to turn the motor is bad and needs to be replaced. If it spins and won't start same thing, If it spins and starts it is probally a start capicator. Shut the power off at the breaker remove the back of the motor the capacitor will be a small black or silver cylinder with 2 or 3 wires clipped to it. Remove this and take it to a motor shop and get an exact duplicate. and that should fix it. When putting back together be sure to lube all "O"rings and refill with water. Hope this helps.

Jandy jhp .75 hums when you turn it on does not pump


It sounds as if motor is spinning and pump is free so the impellar must not be attached to the motor shaft. There is a set screw on the impellar to hold it to shaft or the pump impellar could be cracked. Only way to tell is take the impellar housing off.

what kind of motor or pump? Hayward, pac flo?
