My Aquascape 4500 pump immediately trips the GFI when I plug it into an outlet. This happens both when it is submerged and out of the water. The impeller is not obstructed.

The seal has failed allowing water into the sealed motor unit and it is now shorted to other words the unit is shot and needs to be replaced.

Pump runs for about 3 to 5 minutes and then cuts out the breaker. The outlet is good because I've checked it with other appliances.

You have checked that sure thing, but if you have that pump on a shared circuit that thing draws more amps than normal appliances or is competing with another appliance and popping the circuit. Try isolating the pump and also make sure the circuit can handle the amp load the pump is giving off. Hope this is helpful.. Good Luck!

Torpedo pump...I have one when I plug it trips breaker

I had the exact same issue. I left mine out for the winter and when I plug it in, the breaker trips. My warranty was up so my friend took it apart. The seal had broken alowing water to leak into the bottom the pump where the wires connect to top of motor. This is supposed to be water free and is protected by several seals.

I am currenlty trying to put sealant where the cord goes into unit to stop water from going in. I will let you know how that works.

One tip my friend recommeded is to make sure there is no stress on the cord as it appears this seal is weak and and kind of stress will break it. hope this helps -- Rob

I have a AquaScape 4500 GPH Pump it has worked fine. Today I spent all day cleaning out my pond. All I did was lift the pump out of the pond and spray the muck off it. After completly cleaning the pond and...

Where the wire goes into the pump there is a o ring thatis probably leaking and any sort of water the motor might be getting is tripping the breaker. You probably have it plugged into a gfi and it sense very low amounts of water, and trips, You can determine by plugging it into a regular outlet and it should work. But definently fix the oring at the point of entry on the pump

Aquascape 4500 not working

Typical with these pumps, pumps I have rebuilt that have done the same thing what happens is the bearings get loos and cocks the armature that is why it won't spin. I did serious research on these pumps and came up with a rebuild kit some parts bought some I make. I did mine 2 years ago and still working like a champ and have done over 20 locally with no problems. If your pump is noisy or the impeller has fallen off (typical) due to water getting in the unit and causing the bearings to fail email me and I can rebuild your pump. The process is simple send me the pump I will look at it and see if it can be rebuilt at NO CHARGE if it can be rebuilt you will save over 60% of a new one. Don't spend $349 - $599 on a new one let me look at it for free if I can rebuild it great if not you will have to buy a new one. I am not a dealer for any pumps so you will not have to worry about me selling you a pump and if you want the old one back pay the shipping and it it all yours.
