Question about AO Smith A O Smith Motors Century 1hp 115v Thru - Bolt Lomart Motor - Bv90

1 Answer

A O Smith insulated pool pump runs when turn on and is pushing water but it has a high pitched hum. Was running ok when pool was closed for the winter. I am afraid to leave it run, don't want to blow it up completely. Is there anything that needs lubed? Any other suggestions as to why it seems to be running so hard? Thanks

How to prime an A O Smith pool pump


if the pump is higher than the pool, you should have a ball valve at the front of the pump. close this valve, fill pump housing with water. close the system, open the valve and turn on pump. if the pump is below the pool level, you shouldnt have this problem.

The motor works sometimes but it is very hot.


It's normal for these to run a little hot, a couple things may cause your motor to run hotter than normal.
1. Bad bearings - a local motor shop can take it apart and replace them for around $50. Usually you can tell by a high pitched grinding or squealing noise
2. Wrong impeller - if your impeller is not the correct size for your HP you will be moving too much/not enough water through your pump causing stress to your motor
3. Blocked airway - you can use a can of air on your motors intake grille while it is running to blow out any clogs, if you have low airflow on the exhaust it probably means the airway is blocked

My new AO Smith 2HP pool pump won't pump water, just hums


I'm guessing that you replaced the motor that goes to the pump, not the pump itself. You know the motor works just fine. Is the motor rotating in the correct manner(clockwise or counterclockwise) in relation to the rotation of the pump? Have you checked the pump to see if the impeller is working/rotating? Is the motor hooked up to the pump correctly, so that the motor is turning the impeller? Are all connections to the pump tight, so there are no suction leaks? Have you primed the pump and purged it of any air locks?

High Ringing Noise


Sounds like it just needs lubricating. It's probably dry seals rubbing against the stainless shaft.

Bad bearings usually make grinding noises. Replacing bearings can be a DIY job, but not a teriffically simple one.
