Hayward Matrixs' have a one year warranty.

If it is tripping the circuit that is usually an electrical problem, and has nothing to do with the motor. Open up that back with the motor off and try to turn that shaft with a flat head, if it turns than it is an electrical problem; if it doesn't then contact Hayward directly for warranty information. Hayward is a pain to get ahold of but they are great about honoring their warranties.

The Matrixs' are fairly new and I have yet to see a shaft freeze up.

I have a 1 hp power flo matrix. When I run the pump without water on a bench it runs fine. I put the hoses back on and run it, it starts slow never kicks into full power and trips the braker. Any thoughts?

It sounds like something is causing the motor to not only have limited torque but also draw more than normal current. It sounds like a problem in the motor but exploratory surgery would indicate the cause for sure.

If you are not wanting to turn wrenches yourself then my best suggestion is to bring it to Leslies Pool Supplies and they often can put it right for the price of the parts while you watch.

I hope this helps.

I have hayward 1 h.p. pump cant get it to prime it will pump at a trickle it has to pull 3-4' rise to the pump is this to much height? or is my intake line clogged? or?

The rise is more than ok. You could have a plugged line or a plugged impeller or an air leak. I would look to the suction pipe coming into the pump and the lid and "O" ring on it.

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.

High psi, low intake and output. That possible?

Thank you for posting your question here on

High pressure at the filter means the water is held up and not able to freely flow thru, hence the rise in pressure. If repeated bumps and refills are not working your filter fabric is clogged. You can try to wash them (again I assume) and if necessary even try acid washing as well. If none of these works you'll need to replace the fabric or the entire assemblies which is usually near the price of just replacing the filter.

My new ec50 is clogging frequently. Is at 18 psi

lower the better (psi) this means the water is flowing fast through the filter, high pressures means it's time to clean filter again. keep cleaning until the pool is squeaky clean, then you can go back to cleaning once a week

No water in pump after running for short time

suction side leak... your grabbing air somewhere in the suction line.... take a hose at low pressure and with the pump running put it over various parts of the suction line... including your pump lid... if the problem goes away and you have no more air in the pump then you know what your problem is
