The impeller on this Hayward pump unthreads counter clockwise.
Take a big flat head screw driver and put it on the center shaft on the back of the motor to hold the shaft solid while you unthread the impeller.

The capacitor is probably bad. It's under the cover on the side of the motor, Take a look and smell it. A motor shop has them, or Grainger

SOURCE: The pump only hums when plugged in. Any suggestions?

It sounds like the impellor is locked. Take this part off and then see if the pump is turning but before you do, some of them have a big screw driver slot in the shaft. If it does, turn it to see if you can free the impellor. I have done this many times and they will continue to work for years after. They just get stuck from rust, etc. and also being frozen a little. Hope this helps.

THe skimmer is not pulling much water in from the pool

if you have ever run the pump without the strainer baskets, this might be the problem. it doesnt take much debris to block the impellers and reduce the water flow. if this is the case, you will have to split the pump and use a shop vac to remove all the debris from the impeller

Pump runs but humms


What do I do if my pool/spa pump is humming and has low flow?

Answer: by Osko Pool n Spa Pool/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.

Can I upgrade from Hayward 2hp ao smith pool pump to 2.5hp

Yes you could upgrade the motor from a 2.0 to a 2.5 but this will not result in an increase of your water/pressure flow?
This would slightly reduce the load on the motor as the impeller inside the pump is specifically matched to the your motors amperage.

Check your impeller. Remove the pump motor from the housing to inspect the impeller. Be prepared to replace the seal.

Let me know what you find.

We have an older model Hayward Power Pro LX pump. The pump is running but no water is pumping through. Can't find a tech drawing.

well of course you need to make sure the filters are not blocked up, Skimmer basket etc......I have seen on few occasions the impeller shaft has broken, so the pump runs like it doesn't have a trouble in the world.....but the impeller isn't turning, therefore no water flow.

Powerflo matrix pump is humming not pumping

I think you have a start/run capacitor issue or your impeller has spun its center out. Check the impeller first. If the impeller is intact, take your motor to your full service pool professional for repair.

Hayward flo pump motor repair

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.
