What do I do if my pool/spa pump is humming and has low flow?
by Osko Pool n SpaPool/Spa Pump Humming and No Flow
If your Swimming Pool or Spa Pump Motor is humming and/or has very little or no water flow, please follow the following directions.
1) Remove the pump motor from the system.
2) Disassemble the front half of the Pump Pot Housing from the back half.
3) Check for any foreign obstructions which would jam the Impeller and remove it
4) Next, inspect the Pump Motor Impeller itself. (This is a high suspect part). See if there is any sign of wear or breakage. (This happens over time from debris in the water passing over the impeller). If so, your Impeller is damaged and requires replacement.
5) Next, remove the cover from the rear of the Pump Motor. Using a large standard blade, (straight), screwdriver or wrench... turn the main motor shaft. Listen for grinding and/or rumbling and feel for any restrictions while turning. If you hear or feel either, your bearings and/or brushes are damaged and need replacement.
If everything seems to be in good working order, then you need a new pump... not just replacement parts.

Causes are bearings, debris, windings, or capacitor.
Cut the power and remove the rear end cap covering the motor shaft. Use a 9/16 wrench to turn the motor shaft back and forth. Sometimes this will unseize the bearings. If it gives a lot of resistance the bearings are shot or there is debris jamming the impeller.
The capacitor may have blown out. This is under the cover that sits on top of the motor. See if replacing works.
If all seems okay otherwise, your motor has lost (opened or shorted) some windings and needs to be replaced.
Usualy if it is some years the ball bearing on the motor shaft are rusty and if you can desasemble and use a UD40 lubricant or similar it can be fixed, or replace the bearing. One more posible case is the starting capacitor if it replaced can run the motor again.
Keep trying - It is stuck and will likely break but you have to remove it to change the seal. It is not uncommon to need to replace the impeller when the seal fails since the water gets behind the impeller shaft and rusts the metal causing the impeller to bind. If you still cannot get it free pull the motor thru-bolts and lock the rotor once removed from the motor in a vice. Use a large pair of channel locks to break the impeller free...replace it if necessary.
Inside the back case on the motor you'll see a white piece with two copper colored arms that have two silver points that almost touch. If these are rusty I've found that the motor won't turn over . A quick fix is to take some 600+ grit Aluminum oxide sandpaper and give each of those contact points a brisk sanding to remove any oxidation. This will help the points make a positive contact . Make sure while very obvious that the motor is unplugged first. If your pump has been leaking water it could be that rust has formed on the inside and is preventing the motor from operating properly. Which requires more aggressivedis-assembly to diagnose. You can take it to a motor repair shop if the above listed doesn't work
you are clogging your impeller take a wet vac put hose your using for pump in pool put vac on end of hose to woods and turn on vac long enough to get a water flow and shut of vac it is slower but will save pump
