My Hayward pool pump was humming, but I got it running. Now it is not pulling water into the filter. Does anyone know what the problem could be?

had the pump running at 1 point without being primed and burnt the pump motor up.

Your system has a suction side and a discharge side. Skimmer and bottom drain hook to the suction side. Returns (discharge) return via chlorinator or other sanitary system and heater if appropriate, to ports in the side of the pool.

I think your impeller may be stuck OR your start capacitor has failed. Your pump is going off on over load because it cannot turn or cannot start.

Depends ...

There are two primary valve styles ... a "multi-port" and "push-pull". Never change a valve setting with the pump running.

Multiport has a handle that goes around in a circle (only move it clock-wise). You should go to your pool place to identify this kind of valve and get new lables. Push-pull goes up and down. Up is filter - Down is back wash.

If you will study your system, some things will become evident to you .

Your pump pulls water from the pool through the pump ... out of the pump into the filter. Through the filter, back to the pool. You might be heating the water (would be after the filter) and you may be adding sanitiser (after the heater). One suction - two discharges (oh, the other discharge is to waste.).

Recap ... water out of the pool into the pump - out of the pump throuth the control valve to the filter - out of the filter to the heater then to the sanitiser then back to the pool.

Any help?

Pull the six bolts on the back of the pump and pull the motor and pump housing back. remove the difuser and try spinning the impeller. If it wont spin you may need a new motor. If you pull the wires. You can find a motor shop in your phone book and they can rebuild it for you usually for about 100 bucks. Or replace it with new for a lot cheaper than what your talking. Good luck.

The problem is a malfunctioning check valve. It'll be somewhere in the line on the pump output side. If it's not a separate fitting it'll be in the line, probably in an elbow.

Need further info, let me know...

Check to make sure the plumbing is in the correct inlet/outlet on the valve head. Sounds like it's plumbed backwards. Inlet is from the pump, out to pool...

The motor winding is probably shorted -- needs rebuilding/replacing.
