Hot motor. Blowing fuse.

[Jeff Lebowski]

I ASSUME that the fuse is blowing because of excess heat. The motor is fairly hot to the touch.

Found it dead earlier today. I cleaned out the skimmer. It was a "normal" level of crud. Maybe a quarter full, loosely packed. I cleaned out the pump basket. It was 80 percent free from debris.

The motor is prob about 4-5 yrs old. This is the second one I've installed in the last 12 yrs.

Any ideas? Just an old tired motor or something more sinister? The pressure differential gauge on top of the filter doesn't appear bad at all. I last backwashed about a month ago. Pool sees very little use.

Thanks in advance.

Turn the power off to the pump.
Check the impeller for debris.
Check if the pump spins freely...either by spinning the impeller, or putting a hex wrench in the back of the motor and spinning, if that is available on your pump.

Possibly the wrong motor for the impeller size.

Impeller...........Total HP required.
SPX2600C............0.60
SPX2605C............0.75
SPX2607C............1.10
SPX2610C............1.50
SPX2615C............2.00

SP2600C...1/2 total hp (0.5 to 0.6 H.P).
SP2605C...3/4 total hp (0.75 H.P).
SP2607C...1.0 total hp (1.0 to 1.1 H.P).

Replacing a 3/4 hp with a 1hp pump?

My Hayward 3/4 hp pump just died and I was gifted a 1hp Hayward. Can/should I do it or will it wreak havoc with my system? I have a 28,000 gallon pool. I don’t have the money to upgrade to a vs pump at this point btw.

That pump and impeller match what's been on for a decade or more. And, ran just fine for the last 4-5 seasons. I Will check for internal debris. Thanks!

Fuse or GFCI breaker?

Check amps compared to breaker amp rating.

Check amps compared to motor amp rating.

Check for voltage drop.

Check the impeller model stamped on the impeller vs. the motor total hp.

If amps do not exceed the breaker rating, turn off power and check power wires for continuity to ground.

Do not do any electrical unless you are 100% sure you know how to do it safely.

Does not mean that it was correct.
